Concrete Resurfacing: How an Overlay Renews a Worn Slab

Cory Parks — Thu, 15 Oct 2026 09:22:32 GMT

Concrete resurfacing is a repair method that bonds a thin overlay to the top of an existing slab. The overlay fills shallow pitting and spalling, evens out a rough or worn finish and gives the slab a uniform new surface, without breaking out the old concrete. It is used on walkways, patios, porch slabs, pool decks and garage floors where the slab is structurally sound but the top has worn.

Surface wear in the Carolinas has a few common causes. Freeze and thaw cycles in the mountains and the Piedmont can flake the top of a slab, especially where water sits on it. Heavy summer rain and standing water speed that wear. Settlement is a different problem: a slab that has dropped or tipped needs support from below, and an overlay alone does not change its height.

HydroHelp911 levels settled slabs with polyurethane foam and seals joints and cracks, and this page explains resurfacing so you can compare it with those repairs. Every concrete leveling visit starts with a free inspection of the slab and the cause of the damage.

What to Know About Concrete Resurfacing and How the Method Works

HydroHelp911 lifts settled slabs with expanding polyurethane foam and seals joints and cracks, and this page explains resurfacing so you can compare. In resurfacing, the old surface is cleaned and roughened so the overlay can bond to it.

Damaged spots are filled first, then a thin cement based overlay is spread across the slab and finished to a uniform texture. Because the overlay is thin, it follows the slab beneath it, so a slab that has settled, cracked through or tipped needs its support addressed before any surface work. Foam lifting beneath a settled section fills voids and raises it back toward level.

Resurfacing does not seal the joints between slabs, where water reaches the soil. Joint and crack sealing closes those gaps, and cracks running through the concrete are a sign to look below the surface before renewing the top.

Common Questions About Concrete Resurfacing

What Is the Difference Between Concrete Resurfacing and Concrete Leveling?

Resurfacing renews the top of a slab with a bonded overlay and leaves the slab at the height it sits. Leveling raises a settled slab back toward its original height from below. HydroHelp911 levels settled slabs with polyurethane foam, and the inspection shows whether a slab has a surface problem, a support problem or both.

Can Concrete That Has Cracked or Settled Be Resurfaced?

An overlay follows the slab beneath it, so cracks that are still moving and settlement tend to show through again. A settled slab is usually lifted and its cracks addressed first. The inspection looks at whether the slab is stable before any surface work is discussed.

Is Resurfacing Less Disruptive Than Replacing the Concrete?

Usually, yes. Resurfacing keeps the existing slab in place and adds a thin layer on top, while replacement means breaking out the old concrete and pouring new. For a sound slab with a worn top, an overlay is the lighter repair. For a slab that is broken through, replacement may make more sense.

Will Resurfacing Fix the Reason My Concrete Is Damaged?

Not by itself. Resurfacing renews the surface but does not change the water, soil or drainage that wore or moved the slab. Standing water, open joints and settled sections are part of the inspection, so the cause is addressed along with the surface.

How Much Does Concrete Resurfacing Cost?

There is no set price for concrete resurfacing, because the cost follows the size of the slab, its condition and the overlay used. HydroHelp911 levels settled slabs with polyurethane foam and seals joints and cracks, and the free inspection ends with a written estimate at no cost before any work is scheduled.

DIY Foundation Crack Repair vs. Hiring a Pro: What Every Homeowner Needs to Know

Cory Parks — Tue, 09 Dec 2025 13:31:28 GMT

A thin, dry foundation crack that is not growing can often be sealed yourself with a patch or injection kit. A crack that leaks, keeps growing or comes with bowing walls, sticking doors or uneven floors needs a professional, because the cause has to be found and addressed for the repair to hold.

At HydroHelp911, homeowners across North and South Carolina ask us this question often. This guide compares DIY foundation crack repair with hiring a professional.

Why Do Foundation Cracks Matter?

Foundations crack for many reasons: settling soil, water pressure, changing moisture levels and poor drainage among them. Some cracks are cosmetic. Others can point to movement in the foundation.

When the cause is not addressed, a crack can lead to:

Mold from moisture coming through
Water seepage
Bowing walls
Further movement in the foundation

Freeze and thaw cycles can also widen a crack over time.

Can You Repair Foundation Cracks Yourself?

Sometimes. Here is what a DIY repair usually involves and when it fits.

What Is in a Typical DIY Crack Repair Kit?

Hydraulic cement or epoxy filler
Concrete patch kits
A caulking gun

These work for small cracks that are not structural, such as a crack in a poured concrete wall that is dry, stable and showing no signs of movement or moisture.

When Does DIY Foundation Crack Repair Work?

The crack is hairline thin and not growing
No water is coming through
The crack is on a cosmetic surface, not a load bearing wall
You are not seeing other signs, such as sticking doors, uneven floors or damp smells

If the crack is small, cosmetic and stable, a DIY repair may be all it needs. When you are not sure, an inspection can tell you, because sealing the wrong crack can hide a problem that is still moving.

What Are the Risks of DIY Crack Repair?

The Cause Can Be Missed

A crack can be a symptom of soil movement or water pressure. A DIY patch can cover the crack without addressing that cause, and the wall can keep moving.

Water Can Be Trapped in the Wall

Sealing a crack without dealing with the water around it can hold moisture inside the wall.

A Patch May Have to Be Redone

A DIY kit costs little, but a patch that does not address the cause often has to be redone.

There Is No Warranty

A DIY repair comes with no warranty and no inspection. Our warranty terms and their conditions are on our warranties page.

What Does a Professional Foundation Crack Repair Include?

At HydroHelp911, we look for the cause of a crack and repair it with that cause in mind.

What You Get With a Professional Repair

An inspection of your home's foundation
The likely cause of the crack, such as settlement, water pressure or poor drainage
A repair that fits, from epoxy or polyurethane injection to structural reinforcement
Warranty coverage, with terms and conditions on our warranties page

How Does DIY Compare With Professional Foundation Crack Repair?

Feature	DIY Repair	Professional Repair
Cost Upfront	Low	Set in a written estimate
Finds the Cause	No	Yes, through the inspection
Tools Required	Basic	Specialized
Warranty Included	No	Terms on our warranties page

A DIY repair can make sense for a small, stable crack. For a crack with water, movement or other signs, a professional repair addresses the cause.

What Should You Do About a Foundation Crack?

That depends on the crack. A simple rule of thumb:

If the crack lets water in, is growing, or is part of a larger pattern (such as diagonal cracks, several cracks or bowing walls), have a professional look at it.

If you are unsure, that is what free inspections are for.

Cheapest Ways to Repair a Cracked Foundation

Cory Parks — Tue, 09 Dec 2025 13:04:41 GMT

The cheapest way to repair a cracked foundation depends on the crack. A thin, dry crack that is not moving can often be sealed with an injection kit or sealant for little cost. A crack from soil pressure or settlement needs a repair that addresses that movement, and a free inspection shows which kind you have before you spend anything.

If you have spotted a crack in your basement wall or crawl space, you are probably wondering what it will cost to fix. Foundation repair sounds expensive, but it does not always have to break the bank. At HydroHelp911, we give you options that fit the problem and your budget.

This guide walks through some of the most affordable foundation crack repair options, starting with how to tell what kind of crack you have.

What Kind of Foundation Crack Do You Have?

Before looking at lower cost fixes, it helps to know which kind of crack you have. There are two main types.

Cosmetic Cracks

These are small, narrow cracks, usually vertical or hairline. They often come from concrete curing or minor settling.

Budget tip: These are usually the lowest cost repairs. A tube of sealant may be all you need.

Structural Cracks

These include horizontal, wide or stair step cracks. They come from things like soil pressure, water intrusion or a shifting foundation.

Budget tip: These need more than sealant, but there are still ways to keep the repair cost under control.

What Are the Cheapest Foundation Crack Repair Methods?

A serious foundation problem needs a repair that fits it, but there are ways to keep the cost down and still get a reliable result. These methods run from lowest cost to more involved.

DIY Epoxy or Polyurethane Crack Injection

Best for: Hairline or narrow vertical cracks. Tools needed: An injection kit from a hardware store, safety gear and some patience.

How it works: These kits fill small cracks from the inside with a resin. Polyurethane is flexible and suits cracks that leak. Epoxy cures hard and suits dry cracks.

Pros:

Low cost and fairly easy
Can seal minor water seepage through the crack
Good for small cracks that are not structural

Cons:

Does not address the cause, such as settling or soil pressure
Not for structural damage
The crack can reopen if the wall keeps moving

Our take: For a crack as thin as a pencil line, a kit is one option. If the wall is moving, sealing alone will not stop it.

Waterproofing Paint or Sealant on the Wall

Best for: Damp spots on exposed foundation walls. How it works: A thick waterproof coating on the inside face of the wall helps keep moisture from seeping through.

Pros:

A simple weekend project
Helps with a damp basement
Pairs well with other interior fixes

Cons:

Treats the symptom only
Does not stop deeper cracking
Not a fix for foundation movement

Our take: A coating helps with dampness, but it does not change what is happening in the wall.

Interior Drainage or Vapor Barriers

Best for: Homes with recurring water near minor cracks. How it works: Interior drainage carries water that reaches the wall to a sump, and a vapor barrier helps control moisture. It is not crack repair on its own, but it helps keep water from working on the crack.

Pros:

Helps relieve water pressure on the wall
Helps control basement moisture
Can be combined with crack sealing

Cons:

Does not fix foundation movement
May mean lifting flooring or working in the crawl space

Our take: Water often makes cracks worse, so controlling it is one part of a repair.

Carbon Fiber Reinforcement Straps

Best for: Walls with early horizontal or stair step cracks. How it works: Thin carbon fiber reinforcement straps are bonded to the wall to help keep it from bowing or moving further.

Pros:

Installed from inside the basement
Reinforces the wall
Low profile once installed

Cons:

Works only if the wall has not moved too far
Best installed by a professional

Our take: Carbon fiber is light and strong, and it is installed to help keep a wall from moving further. Warranty terms and their conditions are on our warranties page.

Targeted Piering

Best for: Settling foundations with visible cracks or sagging. How it works: Helical or push piers reach more stable soil to support the foundation.

Pros:

Supports the foundation on more stable soil
Helps stabilize the area against further settling
Can often lift a settled foundation back toward level

Cons:

A larger repair than the options above
Not a DIY option

How Much Does Foundation Crack Repair Cost?

The cost of a crack repair depends on the crack's length and type, the repair method, and whether the crack comes from movement that needs stabilization first. For repairing a foundation crack, our inspector explains the price in a written estimate after a free inspection.

There is no set price for a crack repair, because the method and the cause behind the crack set the work. For a ballpark figure before an inspection, try our foundation cost calculator.

How Can You Save Money Without Sacrificing Quality?

Even when you need a professional repair, there are ways to control the cost.

Get a Free Inspection First

HydroHelp911 offers free foundation inspections, so you know what the crack needs before you spend anything.

Talk Through Your Options

If the budget is tight, tell us. We will walk through your options with you.

Ask About Financing

We offer financing, so the repair can fit your budget.

Does Lower Cost Mean Lower Quality?

A horizontal crack in a wall needs more than caulk. A lower cost repair is about finding the right fix for the problem, not the biggest or most expensive one.

What Are the Signs a Crack Needs a Professional Look?

These signs point to a professional inspection:

It is horizontal or stair stepped
You notice bowing walls or sticking doors
Water is leaking through the crack
The crack is getting bigger over time

Common Questions About Foundation Crack Repair Cost

How Much Does Foundation Crack Repair Cost?

It depends on the crack's length and type, the repair method and whether the crack is a sign of movement that needs stabilization first. There is no set price for a crack repair. Your free inspection gives you a written estimate.

Can I Seal a Foundation Crack Myself?

A thin, dry crack that is not moving can sometimes be sealed with a store bought injection kit. A crack that is horizontal, growing or leaking, or a wall that is bowing, needs an inspection first, because sealing does not address movement.

Does HydroHelp911 Offer Financing?

Yes. We offer financing plans, and your inspector can walk you through them with your written estimate.

Can a Foundation Crack Be Fixed From the Inside?

Cory Parks — Tue, 09 Dec 2025 12:43:37 GMT

Yes, many foundation cracks can be repaired from inside the basement or crawl space. Whether an interior repair is enough depends on the type of crack, what caused it and whether water comes through it. This guide covers how each kind of crack is usually handled and how HydroHelp911 approaches interior foundation crack repair.

What Causes a Foundation Crack?

A crack in a foundation wall can come from concrete shrinking as it cured, from the house settling, from soil movement around the foundation, or from water pressure against the wall. Not every crack points to a problem, and an inspection shows which kind you have.

Can Foundation Cracks Be Repaired From Inside the House?

Short answer: yes, many foundation cracks can be repaired from the inside. Not all of them should be, though.

It depends on three things:

The type of crack
The cause of the crack
Whether the crack is leaking or structural

Here are the most common cases.

Can Hairline and Vertical Cracks Be Repaired From the Inside?

These are the most common cracks we see in poured concrete walls. They usually come from concrete shrinking as it cured or from minor settling, and they are typically vertical or slightly diagonal, and narrow.

Interior crack repair method:

Polyurethane or epoxy injection
Surface seal followed by pressure injection into the crack

How it works: With a clean, dry wall, the resin is injected into the crack from the inside. Polyurethane expands into the crack, and epoxy cures into a rigid bond. The work happens inside the basement, so nothing outside the house is dug up.

Can a Leaking Foundation Crack Be Repaired From the Inside?

A crack that lets water in can often be sealed from the inside, and an interior drainage system can handle the water that reaches the wall.

Interior crack repair method:

Polyurethane injection, which can be used on wet cracks
An interior drainage system (an interior French drain or baseboard system)
Vapor barriers or sealant coatings

How it works: Polyurethane is flexible, so it can move with the wall and expand inside the crack even while it is wet. Paired with an interior drainage system, it can help relieve water pressure against the wall and help keep the basement dry.

If your basement smells musty, sealing the crack may not be enough on its own. The source of the water needs attention too.

Can Horizontal or Stair Step Cracks Be Repaired From the Inside?

Horizontal cracks or stair step patterns in block or brick walls often point to structural movement: the wall may be bowing or being pushed inward by soil pressure.

Interior repair methods that may apply:

Carbon fiber straps, for walls that have started to bow
Wall anchors or steel braces
Polyurethane injection to seal against water, when the crack is not structural

What to expect: If the wall is still moving, the inspection shows which stabilization method fits. Wall anchors and braces stabilize a wall against further inward movement; they do not straighten it.

What Is the Difference Between Inside and Outside Crack Repair?

An interior repair is done from inside the basement or crawl space. The crack is injected, reinforced or stabilized from the inside face of the wall, and water is handled with interior drainage. An exterior repair means digging beside the foundation to reach the outside face of the wall. HydroHelp911 repairs foundation cracks from the inside.

How long a repair takes and what it costs depend on the home, the crack and the soil. The inspector explains both in your written estimate.

What Are the Benefits of Interior Foundation Crack Repair?

Interior crack repair is often a practical first step. When it fits the crack, it offers:

Less disruption: No digging around the outside of your home
Help with leaks: It can seal minor water intrusion and seepage through the crack
Access from inside: The work happens at the wall inside the basement or crawl space

When Is Interior Crack Repair Alone Not Enough?

Sealing alone may not be the right repair if:

The wall is shifting or bowing
Water keeps coming back after the crack is sealed
Several new cracks appear at once, which can point to movement across the foundation

In those cases, an inspection looks for the cause of the movement or the water, so the repair can address it.

How Does HydroHelp911 Handle Interior Foundation Crack Repair?

Here is what happens when you call our team.

Step 1: Free Foundation Inspection

We look at the crack's type, size and likely cause, and you get a written estimate.

Step 2: Interior Crack Sealing (If Appropriate)

Step 3: Further Repairs (If Needed)

We tell you whether interior drainage or wall stabilization would help. We believe in fixing the problem at its source.

Step 4: Warranty Coverage

Our repairs carry warranties with conditions, listed on our warranties page.

Is Interior Crack Repair Right for Your Home?

Many foundation cracks can be fixed from the inside, and for those cracks it is often the simplest repair. The right repair depends on what caused the crack. At HydroHelp911, we recommend the repair a crack needs, and sometimes that means telling you it does not need one.

How to Seal Foundation Cracks: Epoxy vs Polyurethane

Cory Parks — Tue, 11 Nov 2025 18:29:46 GMT

To seal a foundation crack, the two most common methods are epoxy injection and polyurethane injection. Epoxy is the usual choice for a dry crack in a stable wall, because it cures into a rigid bond. Polyurethane is the usual choice for a crack that leaks, because it expands, seals against water and stays flexible. A crack from a bowing or settling wall needs structural repair as well as sealing.

Homeowners often ask us whether a crack is a big deal, whether they can seal it themselves and who to call. Not all cracks are the same, and neither are the methods used to seal them. This guide compares the two most common foundation crack repair methods: epoxy crack repair and polyurethane injection.

Why Do Foundation Cracks Form?

Foundation cracks usually come from one of three things:

Shrinkage: Concrete shrinks as it cures, which creates hairline cracks.
Settlement: The home shifts as the soil underneath moves, from rain, drought or poor grading.
Pressure: Water pressure from outside (hydrostatic pressure) pushes against the walls.

The type of crack says a lot about what is going on. Depending on the cause, foundation crack sealing may be enough, or the wall may need reinforcement or piers.

If the crack is not structural, sealing it properly can help prevent larger problems later.

How Does Epoxy Crack Repair Work?

Epoxy is a two part resin used to bond concrete across a crack.

How It Works

We clean out the crack, install injection ports and pump in two part epoxy resin under pressure. When it cures, it forms a rigid bond across the crack.

Best For

Dry cracks
Vertical or diagonal cracks from shrinkage or minor settling
Cracks in a stable wall that need a structural bond

Not Ideal For

Wet or actively leaking cracks
Cracks that are still moving
Very wide or irregular cracks

Pros of Epoxy Crack Repair

High strength bond across the crack
Flows into fine cracks
Holds up well when the wall is stable and dry

Cons

Does not stop water if the crack is still leaking
Rigid: the crack can reopen if the foundation moves again
Takes longer to install and cure than polyurethane

Bottom Line

If the crack is dry and the wall is stable, epoxy is a strong option.

How Does Polyurethane Injection Work?

Polyurethane is a flexible, expanding resin used to seal cracks that leak or may move.

It is not as rigid or strong as epoxy, but it seals against water, stays flexible and installs quickly.

How It Works

We inject a flexible polyurethane resin into the crack. As it reacts with moisture, it expands and fills the crack, forming a seal against water that can flex with the wall.

Best For

Leaking cracks or cracks exposed to moisture
Cracks that may move with the seasons
Poured concrete walls

Not Ideal For

Major structural repairs
Dry cracks that need a rigid bond

Pros of Polyurethane Injection

Expands to fill the crack
Works on wet or weeping cracks
Flexible, so it can move with the wall through seasonal changes
Cures quickly, with little disruption

Cons

Does not add structural strength
May not bond well in very dry cracks without wetting them first
May need another application if the wall keeps moving

Bottom Line

Polyurethane is a common choice for sealing leaking cracks and controlling moisture. It is less about structure and more about keeping the basement dry.

How Do I Know Which One I Need?

There is no universal rule, but this table shows how the choice usually goes:

Crack Type	Usual Method	Why
Hairline crack, dry	Epoxy	High strength bond across the crack
Leaking crack	Polyurethane	Expands and seals against moisture
Bowing wall with cracks	Structural repair as well	The wall needs reinforcement such as carbon fiber or anchors
Cracks reappearing after repair	Polyurethane, plus finding the cause	Flexibility helps where walls move

A trained inspector looks at:

The direction of the crack
Its width and depth
Moisture conditions
The likely cause, such as settlement or water pressure

At HydroHelp911, we look at the whole foundation and build a repair plan that makes sense for your home.

For more information, see Cracks in Basement Walls: What Do They Mean?

When Is Sealing a Foundation Crack Not Enough?

Crack sealing is not always the whole answer.

If your foundation has structural movement, sagging floors or repeated cracks, sealing alone will not address the cause. The repair may also need:

Steel helical piers to stabilize a sinking foundation
Carbon fiber reinforcement for bowing walls
Interior drainage systems to relieve water pressure

That is why we start with an inspection, with no scare tactics.

Can I Seal Foundation Cracks Myself?

Sometimes. Store bought kits can work on small cracks near the surface. They do not have the pressure injection equipment professional crews use, so they reach less of the crack.

If the crack is structural or leaking heavily, a DIY sealant may hide the symptom while the cause continues. A professional inspection can tell you which kind of crack you have.

For more information, see Fixing Foundation Cracks From the Outside.

Summary of Epoxy vs Polyurethane

How do you seal foundation cracks, and what is the best method? The two most common foundation crack repair methods are epoxy crack repair and polyurethane injection.

Epoxy is used for dry cracks in a stable wall, where it bonds the concrete.
Polyurethane is used for wet or moving cracks, where it expands to seal leaks and flexes with the wall.

HydroHelp911 offers professional foundation crack sealing across North and South Carolina, matched to the type and cause of your crack.

What Is the Best Foundation Repair Method?

Cory Parks — Tue, 11 Nov 2025 18:11:27 GMT

There is no single best foundation repair method for every crack. Epoxy injection suits dry, stable cracks in poured concrete; polyurethane injection suits cracks that leak; carbon fiber straps suit walls that have started to bow; and piers or wall anchors suit cracks caused by settlement or soil pressure. The best method is the one that matches what caused your crack.

At HydroHelp911, we see every kind of foundation crack, from hairline shrinkage cracks to wide cracks that leak. This guide walks through the main foundation repair methods for cracks, how each one works and when each one makes sense.

For more information, see Hairline vs Structural Cracks.

Why Do Foundation Cracks Happen?

Cracks have a cause. In the Carolinas, the most common causes we see are:

Foundation settlement: soil shifting or sinking under the home, often clay rich Piedmont soil that shrinks in dry periods
Hydrostatic pressure: water building up against the outside of a basement wall
Concrete shrinkage: a normal part of curing that creates small cracks
Freeze and thaw cycles and temperature swings: movement that stresses rigid concrete
Poor drainage or grading: water collecting around the foundation

A crack rarely closes on its own, and the right repair depends on its cause.

What Are the Foundation Crack Repair Methods?

Epoxy Crack Injection

Best for: Dry cracks in poured concrete that are not moving. Not ideal for: Wet, leaking cracks or walls that are still moving.

Epoxy crack injection fills the crack under pressure, and the epoxy cures into a rigid bond.

Why epoxy is used:

It bonds the two sides of a crack in a wall that is stable
It flows into thin cracks
It works well on vertical or diagonal cracks

What to know:

Epoxy is rigid, so if the wall moves again, the crack can reappear
It is not the usual choice for a crack that is actively leaking

We typically recommend epoxy when the wall is stable and dry and the homeowner wants a structural bond across the crack.

Polyurethane Foam Injection

Best for: Leaking cracks in poured concrete walls. Not ideal for: Structural cracks that need reinforcement.

Polyurethane injection expands inside the crack and forms a seal against water that can flex with the wall. It does not fix structural problems, but it is a common choice for leaks.

Why polyurethane is used for leaks:

It can seal cracks that are leaking
It stays flexible
It fills irregular gaps

When it is used:

Water is coming through the crack
The crack changes with the seasons
The goal is to seal out water

At HydroHelp911, we often use polyurethane injection as part of a larger foundation repair, especially paired with structural reinforcement.

Crack Sealing (Surface Sealants)

Best for: Hairline cracks that are not leaking or affecting the structure. Not ideal for: Deep, structural or wet cracks.

Crack sealing covers the surface of a crack. It can help with surface water and appearance, but it does not address the cause.

Surface sealants, such as masonry caulk or waterproof paint, are best for minor cosmetic cracks or as a temporary step.

Crack sealing is used when:

The crack is hairline thin
A larger repair is planned later
The area needs protection from surface water

Carbon Fiber Reinforcement

Best for: Structural cracks in walls that have started to bow. Not ideal for: Hairline or surface cracks.

If a basement wall is bowing inward, or cracks run in a stair step pattern along concrete blocks, carbon fiber reinforcement straps are a common repair.

They are thin, sit nearly flat against the wall, and help stabilize foundation walls.

Benefits of carbon fiber:

High strength for its weight
Helps keep cracked walls from moving further
Installed with little disturbance
Warranty terms and conditions on our warranties page

We use this method when a wall needs structural support, often along with crack injection.

Wall Anchors and Pier Systems

Best for: Foundation settlement, larger horizontal cracks and sinking foundations. Not ideal for: Hairline, cosmetic cracks.

When a crack is a symptom of foundation movement, the repair goes below the surface.

Our foundation pier systems (helical or push piers) reach more stable soil below the weak upper layers. Once installed, they support the foundation and help stabilize it against further settlement, and in many cases they can lift it back toward level.

Wall anchors stabilize a bowing wall against further inward movement; they do not straighten it.

If you have cracks along with:

Uneven floors
Doors that stick
Noticeable settlement or tilting

this is the kind of repair we are likely to recommend.

So, What Is the Best Foundation Repair Method?

The short answer: there is not one best method.

The best foundation crack repair method is the one that fits your crack, soil, structure and budget.

That is why every repair HydroHelp911 does starts with a free inspection and a repair plan for your home. We look at the whole structure and recommend a repair that addresses the cause of the crack.

How Does HydroHelp911 Repair Foundation Cracks?

We inspect the foundation inside and around the house
We identify the cause: soil movement, water, construction problems or something else
We match the repair: from injection to full stabilization
Trained crews do the work, and where a repair carries a warranty, its conditions are on our warranties page
We keep you informed: no surprises

Summary

What is the best foundation crack repair method? It depends on the type and cause of the crack. Epoxy crack injection suits dry, stable cracks, while polyurethane injection suits leaks. Carbon fiber reinforcement suits walls that have started to bow, and pier systems or wall anchors are used when cracks come from foundation settlement or soil pressure. HydroHelp911 offers foundation crack repair across North and South Carolina matched to each home.

Are Foundation Cracks Normal?

Cory Parks — Tue, 11 Nov 2025 17:48:24 GMT

Yes, some foundation cracks are normal. Small, vertical hairline cracks often come from concrete curing or minor settling and are usually not a structural concern. Cracks that are wide, horizontal, stair stepped, leaking or growing are different: they often point to foundation settlement or pressure and are worth a professional look.

Owning a home comes with surprises, and a new crack in the basement wall is one of them. This guide covers how to tell normal cracks from serious ones, what causes them and how they are repaired.

Are All Foundation Cracks the Same?

Homes settle, concrete shrinks as it cures, and Carolina weather swings between wet and dry. So some small foundation cracks are normal.

That is why it helps to understand the difference between normal and serious cracks in a foundation.

What Does a Normal Foundation Crack Look Like?

Homeowners across the Carolinas often ask us about a hairline crack in the basement wall and whether to be worried.

In many cases, small, vertical hairline cracks are a result of concrete curing or minor settling. They can appear in the first couple of years after construction and often are not a structural concern.

What Are Normal Cracks Usually Like?

Vertical or slightly diagonal and narrow
Not leaking water or paired with bowing walls
Stable over time, not growing longer or wider

A common crack can still be worth a look, especially if it changes.

For more information, see Are House Settling Cracks Normal?

When Do Foundation Cracks Signal Something Serious?

If you see cracks that are wider, spreading, leaking or paired with other signs, you may be dealing with foundation settlement cracks, and those are worth a professional look.

What Are the Signs a Foundation Crack Is Not Normal?

Cracks that are wide or getting wider
Horizontal or stair step cracks in block walls
Cracks along with bowing walls, sinking floors or sticking doors
Water coming in, or musty smells
Daylight showing through the crack

This is where professional foundation crack repair comes in.

What Causes Serious Foundation Cracks?

In the Carolina Piedmont, homes sit on clay rich soil that swells in wet seasons and shrinks in dry ones, and humidity and uneven rainfall add to that movement. On the coast, sandy soil and a high water table are the bigger factors.

These are the usual causes:

Poor soil compaction during construction
Water pooling around the foundation
Drought or heavy rain
Tree roots pulling moisture from the soil
Aging materials in older homes

All of these can lead to foundation settlement cracks.

For more information, see Cracks in Basement Walls: What Do They Mean?

Why Do Foundation Cracks Matter?

When the cause of a crack is not addressed, it can lead to:

Moisture coming in, which can lead to mold and wood rot
Further movement that can lead to sagging floors and weakened supports

How Does HydroHelp911 Fix Foundation Cracks?

We use foundation crack repair methods that match the cause, such as:

Helical pier systems and push piers to stabilize a settling foundation
Carbon fiber straps to reinforce bowing walls
Epoxy and polyurethane injection to seal cracks
Interior drainage where water is part of the cause

Each home gets a repair plan for that home. Our warranty terms and their conditions are on our warranties page.

How Much Does It Cost to Fix Foundation Cracks?

How much it costs to fix foundation cracks depends on the crack's length and type, the repair method and whether the crack comes from movement that needs stabilization first. Your free inspection gives you a written estimate.

A Quick Summary: Are Foundation Cracks Normal?

Some small, vertical foundation cracks are normal, especially in the first years after construction. They usually come from concrete shrinking or mild settling.

Cracks that are wide, horizontal, leaking or growing over time often point to foundation settlement, and an inspection shows what they need.

If you are unsure whether your crack is normal or serious, HydroHelp911 offers free inspections and foundation crack repair across North and South Carolina. We explain what we find and how it can be repaired, without scare tactics.

Most foundation cracks come from soil movement under or around the house, water pressure against the foundation, construction or material problems, tree roots, seasonal weather and heavy loads. The cause matters because the right repair depends on it.

At HydroHelp911, homeowners across North and South Carolina ask us this question often, and there is usually more than one cause behind a cracked foundation. This post covers the most common causes of foundation cracks, why they happen and what they can mean for your home.

What Are the Most Common Causes of Foundation Cracks?

Soil Movement and Settlement

This is one of the most common reasons for foundation cracks in homes.

Your home sits on soil. When that soil shifts, whether from moisture, poor compaction or natural settling, it can push, pull or drop parts of the foundation unevenly.

How Does Soil Movement Crack a Foundation?

Expansive clay soil, common in the Carolina Piedmont, swells when wet and shrinks when dry.
That movement puts pressure on the foundation from underneath or from the sides.
Over time, the stress can cause vertical, horizontal or stair step cracks.

When the cause is not addressed, this kind of movement can lead to a sinking foundation, bowing walls and further cracking.

How it is repaired: Helical pier underpinning uses steel piers that reach more stable soil and help stabilize the foundation against further settlement in the area where they are installed.

Water Around the Foundation

Water that collects around the foundation, from poor drainage, clogged gutters or ground that slopes toward the house, builds hydrostatic pressure. That means soil heavy with water pushes against the foundation walls.

What Are the Signs of Water Related Foundation Damage?

Cracks near basement windows or doors
Damp or musty smells in the crawl space
Efflorescence (white powdery residue) on concrete walls

Over time, that moisture can lead to cracks, and cracks can let in more water.

How it is repaired: Foundation crack repair paired with interior drainage (such as an interior French drain and sump pump) addresses both the crack and the water. Interior drainage relieves the water pressure, and the crack is sealed.

Construction or Material Problems

Sometimes foundation cracks appear because of how the foundation was built.

What Construction Problems Can Cause Cracks?

Too little reinforcement, such as missing rebar or weak footings
Concrete that shrinks more as it cures
A foundation poured on soil that was not compacted well

These issues can cause early cracking, sometimes within a few years of the home being built, so newer homes can have foundation cracks too.

How it is repaired: An inspection shows what the foundation needs. The repair may reinforce weak areas or add foundation supports.

Tree Roots and Vegetation

Large trees close to the house can affect a foundation in two ways:

Roots displace soil, which creates uneven pressure.
Roots draw moisture out of the soil, which can make it shrink and lead to settlement.

This tends to show up in drier months, when the soil shrinks.

How it is repaired: Stabilizing the settled area addresses the foundation. Trees and landscaping are a homeowner decision, often made with an arborist or landscaper.

Seasonal Weather in the Carolinas

The Carolinas see humid summers, rainy springs and occasional freezing winters. Those temperature and moisture swings make the soil expand and contract, which stresses the foundation over time.

A hairline crack can widen in cold weather and let in water during spring storms, and freeze and thaw cycles can add to that. This is why some foundation cracks change from year to year.

How it is repaired: Foundation crack repair with polyurethane or epoxy injection seals the crack. Moisture control in the crawl space or basement can help keep indoor humidity steady.

Heavy Loads or Structural Changes

Sometimes the cause is what sits on top of the foundation.

A second story, a large deck or structural changes made without reinforcing the foundation can lead to cracks. Heavy features such as stone fireplaces can also stress a foundation that was not designed for the load.

How it is repaired: Piers can support the added load, and wall anchors can stabilize a wall that has started to move inward. We see this often in older homes with newer additions.

What Are the Signs of Foundation Problems?

You do not need to be a contractor to spot the signs. Look for:

Cracks in basement walls or floors
Doors and windows that stick or will not latch
Gaps between walls and ceilings
Sloping or sagging floors
Water stains or pooling in crawl spaces

Why Does Foundation Crack Repair Matter?

A foundation crack does not close on its own. When the cause is not addressed, it can lead to:

A larger repair later
Water getting in, and mold from that moisture
Further movement in the foundation

What Happens If You Don’t Fix Foundation Cracks? Risks Explained

Cory Parks — Tue, 11 Nov 2025 17:07:21 GMT

When a foundation crack is not repaired and its cause is not addressed, water can come through it, and the movement or pressure that opened it can continue. Over time that can lead to moisture damage, bowing walls, uneven floors and sticking doors. Many small vertical cracks are cosmetic, so an inspection is the way to know whether a crack is a problem.

Plenty of homeowners spot a crack, decide it is probably fine and move on, and sometimes it is. This guide covers when foundation cracks are a problem, what they can lead to and how they are repaired.

Are Foundation Cracks Cosmetic or Structural?

Cracks in a foundation fall into two main groups:

Cosmetic cracks: Usually thin, vertical lines that appear as concrete cures or settles. They are worth watching.
Structural cracks: Wider, deeper, horizontal or stair step cracks. They can signal shifting, bowing or settling of the foundation, and they are worth a professional inspection.

It is not always easy to tell the two apart. An inspection shows which kind of crack you have.

What Problems Can Foundation Cracks Cause?

Water Intrusion and Moisture Damage

A crack can let water seep into your home, especially during heavy rain. Once moisture gets in, it can lead to:

Mold and mildew
Musty odors that spread through floors and HVAC ducts
Rot in wood framing and damp insulation
Poorer indoor air quality

A small foundation crack can turn into a basement waterproofing problem.

Structural Movement Over Time

The forces behind a crack, such as shifting soil, water pressure and poor drainage, can keep working on the foundation. Over months or years, when the cause is not addressed, this can lead to:

Bowing or leaning basement walls
Cracked drywall and ceilings inside
Sagging or uneven floors
Doors and windows that stick

These can be signs that the structure is moving.

Problems Throughout the House

Foundation movement can also show up in the rest of the home:

Uneven floors that are easy to trip on
Cracks in plaster and drywall
Water near electrical equipment in a damp basement
Crumbling concrete or masonry

How Does Foundation Crack Repair Work?

A crack does not close on its own, and many widen with seasonal movement. Foundation crack repair addresses the crack and the cause behind it.

At HydroHelp911, we use repairs matched to your home, including:

Pressure injection with polyurethane or epoxy to seal a crack in a foundation and block water
Wall anchors or braces for bowing walls
Helical or push piers to stabilize foundations that have settled
Crawl space repair and encapsulation when moisture comes in from below

Every repair starts with a free inspection, because the right repair starts with the right diagnosis.

What Should You Do If You See Cracks?

Here is a quick checklist:

Watch the crack: is it getting wider or longer, or changing shape?
Check for other signs: sticking doors, sloping floors or water stains
Know the limits of caulk: a DIY patch can hide the crack without addressing the cause
Schedule a professional inspection from a team that works on foundation and moisture problems

What Does a Foundation Crack Look Like?

Cory Parks — Tue, 11 Nov 2025 12:32:21 GMT

A foundation crack is a break in the concrete or masonry of a foundation, and its shape says a lot about its cause. Thin vertical hairline cracks often come from concrete shrinking as it cured. Horizontal cracks often come from soil or water pressing on the wall, and stair step cracks through mortar joints often come from uneven settlement.

At HydroHelp911, we work in crawl spaces and basements across the Carolinas to fix the foundation problems homeowners find. This guide covers what each type of foundation crack looks like, what it can mean and when to have it looked at.

What Is a Foundation Crack?

A foundation crack is a break or split in the concrete or masonry that makes up your home's foundation. Some cracks are cosmetic. Some point to structural movement.

What Are the Most Common Types of Foundation Cracks?

Hairline Cracks

What they look like: Very thin lines, often vertical.

What they can mean: Usually concrete shrinking after it was poured. Most of the time they are cosmetic, but moisture can find its way into a hairline opening.

Vertical Cracks

These run up and down the foundation wall, straight or slightly jagged.

What they look like: Thin to medium width, often running the full height of the wall.

What they can mean: If they are growing, they deserve a closer look. The cause could be soil pressure, water pressure or settling.

Horizontal Cracks

What they look like: A crack that runs across the wall from side to side, usually around the middle of the wall.

What they can mean: Often a structural issue, commonly from water and soil pressure pushing against the foundation. Over time, the wall can bow inward. See signs of a bowing wall.

Stair Step Cracks

These follow the joints of a block or brick wall, up and over like a staircase.

What they look like: A zigzag pattern through the mortar joints.

What they can mean: Common in brick or block foundations, and often a sign of uneven settlement, where one part of the house is sinking more than the rest. See stair step crack signs.

What Other Signs Point to a Foundation Crack?

Even if you do not see a crack, other signs can point to one:

Doors and windows that start to stick or will not latch
Sloping or uneven floors
Gaps between walls and the ceiling or floor
Water seepage or musty odors in the basement or crawl space
Crumbling concrete or brick

Each of these can trace back to foundation movement, and sometimes to a crack that has widened over time.

Why Do Foundation Cracks Matter?

When the cause is not addressed, small cracks can let water in, and moisture can lead to mold, wood rot and further damage over time.

How Do You Tell Structural Cracks From Cosmetic Ones?

Cosmetic cracks, such as small hairline or vertical cracks, are usually minor, but they are worth watching.

Structural cracks, such as horizontal cracks, wide vertical cracks, stair step cracks or any crack that leaks water, are worth a professional inspection. They can be signs that the home is moving.

If a crack is growing or comes with signs of movement, such as tilting walls or shifting floors, that is a good reason to schedule an inspection.

How Does HydroHelp911 Fix Foundation Cracks?

We look for the cause behind a crack, such as soil movement, water pressure, poor drainage or construction problems, and repair it with that cause in mind.

Step 1: Free Inspection

We look at your home inside and around the foundation, check for movement and moisture, and identify the likely cause.

Step 2: Repair Matched to the Crack

Depending on the crack and its cause, we may recommend:

Foundation Repair Methods for a Shifting House

Cory Parks — Mon, 29 Sep 2025 11:44:26 GMT

The main foundation repair methods for a shifting house are steel piers (helical, push or slab piers) that carry the house down to more stable soil, wall anchors and carbon fiber straps that stabilize bowing basement walls, and crawl space jacks that support sagging floors. Which one fits depends on what is moving and why, and an inspection shows that.

If floors feel uneven, doors do not shut the way they used to or new cracks appear, the house may be shifting. Here is a look at foundation repair methods, the signs of a problem and the repair options.

What Causes a House to Shift?

A shifting house usually comes down to the soil under it. Much of the Carolina Piedmont has clay rich soil that swells in wet weather and shrinks in dry weather. On the coast, sandy soil and a high water table are the bigger factors, and in the mountains, slopes and runoff. Poor drainage, erosion and heavy rain add to that movement.

Other causes include:

Poor grading around the home
Plumbing leaks under the foundation
Tree roots drawing moisture from the soil
Time and gravity

A house is only as stable as the ground it sits on. When that ground shifts or sinks, the house moves with it.

What Are the Common Signs of Foundation Problems?

If you see these signs, an inspection can show what they mean:

Cracks in the drywall, especially around doors and windows
Uneven floors or sloping rooms
Sticking doors and windows
Gaps between walls and ceilings
Cracks in the foundation itself
Water pooling around the foundation after rain

If you have any of these, it is worth looking at your foundation repair options for a shifting house.

Which Foundation Repair Methods Work for a Shifting House?

These are the methods we recommend, depending on what the inspection finds.

Helical Piers

Helical piers are steel shafts with plates shaped like a screw. They are turned into the ground beside or under the foundation until they reach stable soil or rock.

Best for: Lighter structures or areas with poor soil. How it helps: The piers carry the weight of the home down to firmer soil below the weak upper layers. How deep they go depends on the soil at your home.

Push Piers

Push piers work on a similar idea, but they are driven straight into the ground using the weight of the house.

Best for: Heavier homes with more settlement. How it helps: The piers support the sinking sections of the foundation and help stabilize them against further settlement.

Slab Pier Systems

If your home is built on a concrete slab and you have noticed cracking or settling, slab piers can support those areas from underneath.

How it helps: The piers support the slab directly and help limit further movement.

Wall Anchors

If foundation walls are bowing inward, wall anchors can stabilize them.

Best for: Basements with bowing walls. How it helps: Steel plates on the inside of the wall are connected by rods to anchors set in firm soil outside the home, which stabilizes the wall against further inward movement. Anchors stabilize a wall; they do not straighten it.

Carbon Fiber Straps

When a wall has moved only a little, carbon fiber straps reinforce basement walls without taking up space.

How it helps: The straps help keep the wall from moving further and sit nearly flat against it. Warranty terms and their conditions are on our warranties page.

Crawl Space Jack Posts

If floors feel bouncy or sloped, the cause may be under the house. Crawl space jacks add support where beams have sagged or their supports have failed.

How it helps: The jacks support the beams on solid footings and, where the framing allows, can raise a sagging floor back toward level. Tip: Pairing them with crawl space encapsulation helps control the moisture that can weaken wood framing.

What Can Happen When Foundation Problems Are Not Addressed?

When the cause of a shifting house is not addressed, cracks can grow and floors can sink further. Foundation problems can also lead to:

Water getting in
Insects in damp wood
Mold from moisture
Further structural movement

Most Common Crawl Space Problems and How to Fix Them

Cory Parks — Sun, 28 Sep 2025 16:25:28 GMT

The most common crawl space problems are standing water, high humidity, mold, pests, sagging floors, failed insulation, wood rot, open vents and musty smells. Most of them trace back to moisture, so the usual fixes are drainage, encapsulation and a dehumidifier, with structural repair where the floor framing has weakened.

Your crawl space is out of sight, but its condition affects the rest of your home. This guide covers the most common crawl space problems and how they are fixed, with no scare tactics.

Moisture and Standing Water

A crawl space that holds water after every rain can lead to mold, wood rot, pests and structural problems.

What causes it?

Rain and roof water that does not drain away from the house
Cracked foundation walls
Groundwater seepage
A missing or failed vapor barrier

What is the fix?

An interior drainage system: an interior crawl space drainage system (interior French drain) and a sump pump carry water out of the crawl space.
Encapsulation: a heavy liner and a dehumidifier help keep ground moisture out of the air under your floors.

High Humidity

Even without standing water, high humidity can damage a crawl space over time. Humid air can lead to mold, musty smells and poorer air quality that reaches the rooms above.

What causes it?

Open vents
Poor air circulation
No dehumidification
Moisture from the ground below

What is the fix?

A dehumidifier for an encapsulated crawl space to control the moisture level
Sealed vents and doors to keep humid outside air out
Encapsulation to block ground moisture at the source

Why it matters: Some of the air in your home comes up from the crawl space, so a drier crawl space helps the air upstairs.

Crawl Space Mold

Mold grows in damp, dark places like a crawl space. It is a symptom of moisture, and it can affect the air quality in your home.

What causes it?

Long term moisture
Little air movement
High humidity and wood to grow on

What is the fix?

Long term moisture control with encapsulation and a dehumidifier
Replacing damaged insulation or wood where needed

Rodents and Pests

Mice, snakes, insects and other animals can move into a crawl space that has a way in.

What causes it?

Gaps around vents, pipes and doors
Damaged crawl space walls
Easy access from outside

What is the fix?

Sealing entry points with proper covers
Pest resistant vent covers
Encapsulating and closing off the crawl space, which leaves animals fewer ways in and less shelter

Tip: A sealed crawl space can help keep pests out.

Sagging Floors Above

A floor that bounces or dips can point to the support system under it.

What causes it?

Floor joists weakened by moisture
Support beams that are too few or failing
Soil settling under the piers

What is the fix?

Crawl space jack posts to support sagging areas
Replacing damaged wood or framing
Fixing the moisture problem first, so the new support is not working against damp wood

Insulation Failure

Old insulation can absorb moisture. Once it is wet, it can sag, fall and lose its insulating value, and sometimes grow mold.

What causes it?

Moisture
Rodents nesting in it
Age and wear

What is the fix?

Removing the old insulation
Encapsulating the crawl space to control moisture
Using insulation suited to crawl spaces, such as rigid board insulation on the walls

Tip: Failing insulation can raise energy bills. A dry, sealed crawl space can help your heating and cooling system work less.

Wood Rot

Wood rot in a crawl space can weaken beams and joists over time, and it can be hard to see from above.

What causes it?

Long term moisture
Fungus growing on damp wood
No drainage or moisture control

What is the fix?

Replacing rotted wood
Fixing the source of the moisture

Open Crawl Space Vents

Many older crawl spaces were built with vents meant to let them breathe. Those vents can also let in humid air, pests and temperature swings.

What causes it?

Open crawl space vents
No control over the air coming in

What is the fix?

Sealing the crawl space vents once the crawl space is encapsulated
Encapsulation to keep the air clean and dry
A dehumidifier to manage the air inside

Bottom line: With full encapsulation and a dehumidifier, the vents stay closed.

Musty Smells

A musty odor in your living room can come from the crawl space. Mold, mildew or animal droppings can cause it.

What causes it?

Mold and mildew
Rotting insulation or other materials
Standing water or pest waste

What is the fix?

Removing wet, decaying materials
Encapsulation and moisture control to help prevent odors

How Do You Fix Crawl Space Problems?

At HydroHelp911, we see sagging beams, flooded crawl spaces and animals that have moved in. Here is how our process works:

Free Crawl Space Inspection: We check the whole crawl space and show you what we find.
Repair Plan for Your Home: We match the repair to your crawl space.
Permanent Solutions, Not Patch Jobs: Encapsulation, drainage, jacks and dehumidifiers that address the cause, so the crawl space stays drier and cleaner.

Our warranty terms and their conditions are on our warranties page.

What Can Happen If Crawl Space Problems Continue?

When the cause is not addressed, crawl space problems can grow over time. If you have noticed a sagging floor, a musty smell or signs of moisture under your house, a free inspection can show what is causing it. Book your crawl space inspection online.

Concrete Grinding: How a Raised Slab Edge Is Shaved Flush

Cory Parks — Tue, 16 Sep 2025 18:01:19 GMT

Concrete grinding is a surface method that removes concrete from the top of a slab. A grinder with diamond tooling shaves down the raised edge where two slabs meet, or a high spot on one slab, so the surface sits flush and walks evenly. It comes up most often on sidewalks, patios and garage floors, where one section has risen or another has dropped and left a lip that catches a foot or a wheel.

The lip itself usually starts in the ground. Across the Piedmont, clay under flatwork swells in wet seasons and shrinks in dry ones, so sections rise and fall unevenly. In the Sandhills and along the coast, sandy soil can wash out from under a slab and let it drop. Tree roots can also push a section up from below. Grinding works on the high side of the joint, so it suits a slab that is stable and only slightly out of line.

HydroHelp911 levels settled concrete by lifting the low slab with polyurethane foam, and this page explains grinding so you can compare the two. Every concrete leveling visit starts with a free inspection of the slab and the cause of the movement.

What to Know About Concrete Grinding and How the Method Works

HydroHelp911 lifts settled slabs with expanding polyurethane foam, and this page explains concrete grinding so you can compare them. Grinding removes material from the high side of an uneven joint until it meets the low side.

The grinder makes controlled passes across the raised edge, feathering the surface so the change in height is gradual. The slab stays where it is, so grinding suits a small, stable offset. When a section has sunk, lifting the low slab with foam addresses the low side instead, and foam injected beneath the slab also fills the void that let it drop.

Grinding does not change what moved the slab, so a trip hazard at a joint can return if the soil or a root keeps moving it. Sealing the joints between slabs keeps water from soaking the soil below, and it is one of the concrete services HydroHelp911 provides.

Common Questions About Concrete Grinding

Does Concrete Grinding Lift a Sunken Slab?

No. Grinding removes concrete from the high side of a joint, so it lowers the raised edge and leaves the low slab where it is. Lifting raises the low slab back toward level. HydroHelp911 lifts settled slabs with polyurethane foam, and the inspection shows whether a slab has sunk or the neighboring one has risen.

What Kinds of Surfaces Is Concrete Grinding Used On?

Grinding is commonly used on sidewalks, walkways, patios, porch landings and garage floors, wherever a raised edge creates a trip hazard on concrete that is otherwise sound.

Will Grinding Fix the Reason My Slabs Became Uneven?

Not by itself. Grinding smooths the surface but does not change the soil, water or roots that moved the slab, so the offset can return if the cause stays active. The inspection looks at drainage near the slab, the soil and any nearby trees.

Does Concrete Grinding Weaken the Slab?

Grinding takes material off the top surface, so it is generally used for small offsets where enough concrete remains. A larger offset usually points to a slab that has moved, which is a leveling question for the inspection.

How Much Does Concrete Grinding Cost?

There is no set price for concrete grinding, because the cost follows the number of joints, how far each edge stands up and access to the area. HydroHelp911 levels settled slabs with polyurethane foam, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Foundation Replacement: When It’s Necessary and How It Works

Cory Parks — Tue, 09 Sep 2025 13:02:19 GMT

You’ve probably heard the saying, “built on a solid foundation.” It’s true for relationships, businesses, and, most importantly, your home. If that foundation fails, the rest of the structure is affected.

Sometimes, repairs are enough to keep things stable. Other times, your home needs a complete foundation replacement, a full reset of the very thing holding everything up. This isn’t a “slap on some mortar and call it good” situation. We’re talking about pulling your house up off the ground, ripping out the old bones, and giving it an entirely new base to stand on.

Let’s break down when it’s necessary, what it takes, and what you can expect from the process.

When You Might Need to Replace a Foundation

Foundation replacement is the largest kind of foundation project. It’s not the first move, it’s the last resort. Most foundations can be stabilized or repaired with solutions like piers, wall anchors, or interior drainage. But there are times when a full foundation rebuild is the only real fix.

Here’s when you might need it:

Severe Settlement

If the settlement is extreme or very uneven, repairs may not be enough. Severe settlement often comes from poor soil conditions, erosion, or improper construction.

Structural Failure

This is the big one. If your foundation walls are bowing or crumbling, that can be a sign of structural failure. Think rotting wood in a crawl space rebuild or concrete slabs that are more crack than concrete.

Irreparable Cracking

Some cracks are cosmetic. Others are warning signs. When the cracks are wide, jagged, and keep growing despite repairs, you may be looking at a foundation replacement.

Water Damage Beyond Repair

Water is sneaky. Over the years, it can undermine footings, wash away soil, and rot supporting beams. If drainage issues continue long enough, you may need more than a sump pump, you may need a new foundation.

Major Renovations or Home Lifting

If you’re adding a basement where there wasn’t one before, or doing home lifting to protect from flooding, replacing the foundation might be part of the project.

The Process: How a Full Foundation Replacement Works

You can’t exactly swap out a foundation like a pair of socks. It’s a carefully planned process done in steps that takes precision, the right equipment, and a crew who knows what they’re doing.

Here’s what the journey looks like:

Step 1: Inspection & Planning

Before any dirt is moved, a structural expert inspects your home to confirm a replacement is necessary. It is a detailed assessment of soil conditions, the structure and safety risks.

Step 2: Permits & Engineering

Replacing a foundation is not a “weekend project.” You’ll need engineered plans, building permits, and sometimes inspections from local authorities.

Step 3: Lifting the House

This is the part that blows most homeowners’ minds. Using hydraulic jacks and steel beams, the entire house is lifted off the old foundation. Every inch counts: lift too little, and you can’t work underneath; lift too much, and you’re starring in your own “DIY disaster” video.

Step 4: Foundation Demolition

Once the house is safely supported, the old foundation is demolished. This can mean breaking apart concrete footings, removing rotted wood beams, and clearing debris down to bare soil.

Step 5: Building the New Foundation

Here’s where the magic happens. Whether it’s a slab replacement, poured concrete walls, or block foundation, the new structure is built to today’s codes and customized to your home’s needs. For crawl spaces, this might include moisture barriers and reinforced piers.

Step 6: Lowering the House & Reconnecting Utilities

The home is carefully lowered back onto its new foundation and adjusted to sit level. Utilities (plumbing, HVAC, and electrical) are reconnected.

Step 7: Final Inspection & Cleanup

Before anyone signs off, the work is inspected and the site is cleaned up.

How Long Does Foundation Replacement Take?

How long a full foundation rebuild takes depends on the size of the home, the soil and how complex the job is, and the contractor who does the work sets the schedule.

And yes, weather matters. Rain, snow, or frozen ground can slow the process.

The Cost of a New Foundation

Let’s address the question that’s already rolling around in your head: “What’s the cost of a new foundation?”

There is no single answer. The price depends on:

Foundation type (slab, crawl space, full basement)
Square footage of your home
Extent of structural failure
Soil conditions
Access to the site (a tight city lot or an open rural lot)
Additional work (like drainage systems or home lifting)

Foundation replacement is a large project. The good news is that it often is not necessary.

What If You Don’t Need a Full Replacement?

Foundation replacement sounds extreme, and sometimes it is. But here’s the good news: many homeowners don’t need it. Many foundation problems can be addressed with repairs that leave the existing foundation in place.

Foundation repair options are designed to stabilize and protect your home without tearing everything out. That’s why the first step is always a professional inspection. What looks like a total failure might actually be repairable with the right tools and techniques.

At HydroHelp911, we specialize in foundation repair solutions like:

Helical and push piers to support and help lift sinking foundations.
Wall anchors and carbon fiber straps to stabilize bowing or cracking basement walls against further movement.
Interior drainage and waterproofing to help keep water from weakening the structure.

These repairs help protect your home without the disruption of a full replacement.

What Can Happen If Foundation Problems Continue?

Foundation problems can get worse over time, with more cracks, more settlement, and more water damage. An inspection shows what is happening and which repair fits.

When in doubt, get an inspection. A repair may be all your foundation needs, and an inspection shows whether it is.

Are House Settling Cracks Normal? Signs, Causes & Repairs

Cory Parks — Tue, 09 Sep 2025 12:49:14 GMT

Small cracks from normal settling are common in most homes, and many of them are cosmetic. Cracks that keep growing, run horizontally or in a stair step pattern, let water in or come with sticking doors and uneven floors can point to foundation movement, and an inspection shows which kind you have.

Cracks in a home are unsettling, so this guide covers which ones are usually normal, what causes them and how they are repaired.

Are All Settling Cracks the Same?

Every home settles. Soil moves, temperatures change, and building materials expand and contract. That normal movement often causes small cracks, such as hairline cracks in drywall or minor gaps near windows or doors, that can be patched and painted.

When cracks grow longer, wider or more jagged, they may be more than cosmetic, and an inspection can show what is causing them.

How Can You Tell What a Crack Means?

You do not need to be a structural engineer to notice when something has changed. These are the common types:

Vertical Cracks

Vertical cracks in foundation walls often come from normal settling. They are usually the least concerning, but they are worth watching. If one grows or lets water in, an inspection can show the cause.

Horizontal Cracks

A horizontal crack along a basement wall can mean pressure from the soil outside, often from soil movement or water. Over time, the wall may start to bow.

Stair Step Cracks

If a crack in a brick or block foundation runs in a stair step pattern, especially near corners, it can point to foundation movement. It is one of the more common signs of settlement in homes on soil that shrinks and swells.

Drywall Cracks

Drywall cracks often show up above windows, doors and in ceiling corners. Some are cosmetic. If doors are sticking, floors are uneven, or cracks come back after repairs, the house itself may be shifting.

Floor Settling or Uneven Floors

Sloping or bouncing floors often point to a problem below the surface, such as foundation settlement or weakened support beams in the crawl space.

Why Do Settling Cracks Happen?

These are the usual causes:

Expansive Soil: The Carolina Piedmont has clay rich soil that swells when wet and shrinks when dry, and that movement pushes on the foundation.
Poor Drainage: Water that does not drain away from the home can erode soil or saturate the ground, which can lead to movement.
Footing or Construction Problems: Sometimes the cause goes back to how the home was built.
Time and Gravity: Even well built homes settle. How they settle makes the difference.

When Should You Have a Settling Crack Inspected?

Size is only part of it. What the crack is doing matters too:

Is it growing?
Is it horizontal or stair step?
Is water getting in?
Are doors and windows harder to open?
Are your floors uneven?

If you answer yes to any of these, the cracks may be more than cosmetic. An inspection can show what is causing them.

How Does HydroHelp911 Repair Settling Cracks?

We look for the cause of a crack before recommending a repair, because a repair works best when it addresses that cause.

Foundation Crack Repair

Our crack repair work seals cracks with injection and, where a wall needs it, adds structural reinforcement. Addressing what caused the crack helps keep new cracks from forming.

House Leveling

Using pier systems such as helical or push piers, we stabilize the foundation and, where the house allows, lift it back toward level.

Crawl Space Support

Sagging floors often trace back to the crawl space. Adjustable crawl space jacks can support the floor framing from below, and a vapor barrier helps control the moisture that can weaken wood.

Basement Wall Stabilization

For bowing or cracked basement walls, wall anchor systems or carbon fiber straps stabilize the wall against further inward movement. They do not straighten the wall.

Why Does a Crack Inspection Matter?

A free inspection shows what is causing a crack and whether it needs repair. The inspection costs nothing.

So, Are House Settling Cracks Normal?

Often, yes. Small cracks from natural settling are common. Cracks that grow, shift, leak or multiply are different, and they are worth having inspected.

An inspection shows what is happening. Caulk can cover a crack, but it does not address what caused it.

Hairline vs. Structural Cracks: What’s the Difference?

Cory Parks — Thu, 26 Jun 2025 17:07:25 GMT

A hairline crack is a very thin, surface crack that usually comes from concrete shrinking as it cures, and it is usually cosmetic. A structural crack is wider, may go through the wall, often runs horizontally or in a stair step pattern, and can grow, which can point to foundation movement. The difference between hairline and structural cracks often shows most clearly in how a crack changes over time.

This guide explains what each type of crack means, why it happens and how foundation crack repair addresses it.

What Is a Hairline Crack?

A hairline crack is a very thin crack in concrete. These cracks often show up when concrete dries and shrinks, especially in new foundations or patios.

Are Hairline Cracks a Structural Problem?

Most hairline cracks are cracks that are not structural, which means they don’t harm the strength of your home. But they still matter.

Water can seep in through small cracks. This can lead to mold, mildew, or even more damage over time. Bugs and pests can also enter through hairline cracks. So, even though these cracks are usually not structural, they can still let water and pests in.

Common Causes of Hairline Cracks

Hairline cracks can happen when concrete dries too fast or when a new home settles a little bit after being built. They also show up due to changes in temperature or from shrinking while the concrete cures. If you’re seeing tiny cracks but no other problems, it’s likely a hairline crack. It is still worth keeping an eye on it, or sealing it to help keep moisture out.

What Is a Structural Crack?

A structural crack is more serious. These cracks can show that your home’s foundation is moving or shifting.

Signs of a Structural Crack

You might be dealing with a structural crack if the crack is wide, goes all the way through the wall, or forms a stair step shape in brick or block walls. Cracks that are horizontal, jagged, or continue to grow are also signs. If doors or windows start sticking or won’t close, it may point to a deeper foundation problem.

What Causes Structural Cracks?

Structural cracks can be caused by soil moving under the home, water damage from poor drainage, or freeze and thaw cycles in colder weather. Sometimes, tree roots push against the foundation, or poor construction methods weaken the structure. When the cause is not addressed, these cracks can grow and can lead to uneven floors, wall damage or other foundation problems.

How Can You Tell a Hairline Crack From a Structural Crack?

Knowing whether a crack is just a hairline crack or a structural crack can be tricky. Here are some tips:

Feature	Hairline Crack	Structural Crack
Width	Very thin	Wider, often wide enough to see into
Pattern	Thin and straight	Stair step, horizontal or jagged
Depth	Surface only	Goes through the wall
Change Over Time	Stays the same	Gets bigger or longer
Impact	Cosmetic	May point to structural movement

Width alone does not decide it. When you are not sure, a professional inspection can tell you.

Why Do Foundation Cracks Matter?

A small crack can grow. Cracks can let water in, which can lead to mold, and they can let ants, termites or rodents in.

A crack can also be a sign that a home is settling unevenly. When that is not addressed, it can lead to uneven floors, leaning walls, cracked ceilings or water in a basement or crawl space.

What Is Foundation Crack Repair?

Foundation crack repair means sealing or reinforcing cracks in a foundation and addressing what caused them. The repair method depends on the crack type.

How Are Hairline Cracks Repaired?

Hairline cracks are often repaired by injecting epoxy or polyurethane into the crack. Surface sealants can be used to keep out water. It’s also a good idea to monitor the crack over time to see if it grows or changes.

How Are Structural Cracks Repaired?

Structural cracks need more than sealing. Carbon fiber reinforcement can strengthen a wall that has started to bow, and wall anchors or braces can stabilize a bowing wall against further inward movement. In some cases, underpinning with piers is used to stabilize a settling foundation.

Each repair starts with an inspection that finds the cause of the crack and the repair that fits it.

Can You Repair a Foundation Crack Yourself?

It might be tempting to fix a crack yourself with a quick patch from the hardware store. But a patch may not address what caused the crack.

DIY repair often only treats the surface. You might seal the crack, but not fix what caused it in the first place. That means the crack can come back or get worse.

The wrong material can also cause problems. A product that does not bond well with concrete can leave leaks or a poor seal.

Without an inspection, signs of a structural problem can be missed, and the cause can go unaddressed. That is why a foundation inspection can help.

When Should You Call a Professional?

Not sure what kind of crack you have? Here are signs a foundation expert should take a look:

If the crack is growing, if you see more cracks forming, or if the crack goes through the wall, it needs a closer look. Horizontal or stair step cracks also deserve a closer look. If your doors or windows won’t close right, or if the crack is leaking water, a professional inspection can show the cause.

Even if a crack seems small, having it checked can tell you where you stand.

How Can You Help Prevent Future Cracks?

You cannot stop every crack, but a few homeowner habits help: keep gutters clean, make sure downspouts drain away from the house, plant large trees well away from the foundation, and watch for early signs such as sticking doors or sloping floors.

Cracks in Basement Walls: What Do They Mean?

Cory Parks — Thu, 26 Jun 2025 17:07:24 GMT

Most cracks in basement walls come from concrete shrinking, normal settling or water and soil pressure against the wall. Thin vertical cracks are often minor; horizontal cracks, cracks that grow and cracks that leak usually point to pressure or movement that an inspection should look at.

Let’s talk about the different kinds of cracks in basement walls, what they mean, what causes them, and how to fix them.

Why Do Basement Walls Crack?

Basement walls can crack for a few reasons. One common cause is the natural settling of your home. As soil shifts or compacts under the foundation, the pressure can lead to cracks. Changes in temperature, water pressure, and construction flaws can also play a part.

When the ground around your home gets too wet, it expands. When it dries, it shrinks. This movement can stress your basement walls. Over time, cracks appear.

Some cracks are normal. But others can let water in, weaken your walls, or point to a structural problem. That’s why it’s important to look closely.

What Are the Types of Basement Wall Cracks?

Hairline cracks in basement walls are very thin and often caused by concrete shrinkage. These are usually not a structural concern, and sealing them helps keep water and pests out.

Vertical cracks in basement walls run up and down. These cracks are often due to settling and may not be serious if they don’t grow over time.

Horizontal foundation cracks are a bigger concern. They often mean that outside pressure is pushing against the wall. This can happen from water buildup, heavy soil or poor drainage. When the pressure is not addressed, these cracks can widen and the wall can start to bow.

Diagonal cracks can form from uneven settling. One side of the wall might be moving more than the other. These cracks may be small at first, but they can lead to larger problems over time.

What Do Cracks in Basement Walls Really Mean?

A small crack doesn’t always mean big trouble. But some cracks are signs of structural damage. It depends on the size, shape, and location of the crack. If the crack is getting longer or letting in water, an inspection can show what is causing it.

Water stains or a musty smell near the crack could mean you have a leaking basement wall. Moisture can cause mold, rot, or damage to anything stored in your basement. It can also weaken the wall itself.

When cracks grow quickly or show up in several places, it might mean the foundation is shifting. In that case, you may need structural wall crack repair.

How Do You Fix Cracked Basement Walls?

Fixing a crack depends on what caused it. For minor cracks, sealing with epoxy or polyurethane can keep water out. This is usually done through basement crack injection, which fills the crack from the inside.

For larger or more serious cracks, the wall may need reinforcement, such as carbon fiber straps or wall anchors. These help stabilize the wall against further movement; wall anchors stop further inward movement but do not straighten a wall.

If water is part of the problem, waterproofing is part of the repair. That can mean sealing the walls or adding interior drainage and a sump pump. Managing the water around the wall helps keep cracks from coming back.

Can You Repair Basement Wall Cracks Yourself?

It might be tempting to fix a crack yourself. You can find sealants and fillers at hardware stores. But a surface repair may not address what caused the crack.

Most DIY repairs cover the surface only. If the crack comes from structural movement or water pressure, sealing it may not stop the problem, and the crack can return.

A professional inspection shows which type of crack you have and what caused it.

When Should You Call a Basement Crack Expert?

If a crack leaks, gets bigger or looks serious, a free inspection can show what is causing it. Even when a crack seems small, an inspector can tell you what is going on.

The inspector looks at your basement, finds the cause and recommends a repair that addresses it, along with any waterproofing that would help.

How Can You Help Protect Your Basement From Cracks?

A few homeowner habits help: keep gutters working, keep roof water away from the foundation, and plant new trees well away from the house.

Regular inspections also help, because small cracks are often easier to repair. If your home is older, or you have had water problems before, it is a good idea to have your basement checked.

Slab Lifting for Garage Floors: Is It Worth It?

Cory Parks — Thu, 26 Jun 2025 17:07:24 GMT

Slab lifting is often worth it for a garage floor that has sunk or tilted, because it raises the existing slab back toward level instead of tearing it out. Whether it fits your garage depends on why the slab sank and the condition of the concrete, which a free inspection shows.

If your garage floor looks uneven or cracked, one side has dropped, or water will not drain, you are not alone. This guide covers what slab lifting is, how it works, what affects the cost and whether it is right for your home.

What Is Garage Floor Leveling?

Garage floor leveling means raising low or uneven spots in a concrete floor. Over time, concrete can sink or settle because of soil movement, water or poor construction. Slab lifting, also called concrete lifting, raises the sunken concrete back toward its original position.

It addresses an uneven garage floor without replacing the slab. Instead of tearing out the floor, slab lifting fills the gaps under the concrete and lifts it back into place.

Why Do Garage Floors Sink?

A garage floor can sink for several reasons. The soil under the concrete can shift as its moisture changes, heavy rain or poor drainage can wash soil away, and sometimes the soil was not compacted well when the slab was poured. In the Carolina Piedmont, clay soil that shrinks in dry weather is a common cause; on the coast, sandy soil that washes out is more common.

When the ground under a garage floor is not stable, the concrete above can sink, crack and dip.

What Are the Signs You Need Garage Floor Repair?

You may notice cracks across the garage floor, gaps between the floor and the walls, or water that pools in one spot and will not drain. These can all mean the floor is no longer level.

A floor that has dropped on one side can also put stress on the garage walls, so garage floor repair can be about more than looks.

How Does Slab Lifting Work?

Our garage floor leveling uses polyurethane foam injection. Small holes are drilled in the sunken areas, and polyurethane foam is injected under the slab. The foam fills the gaps and lifts the concrete back toward level.

The holes are then patched and the area is cleaned up. How long the work takes depends on the size of the area and the soil, and the inspector explains it with your estimate.

Why Is Garage Floor Leveling Worth It?

An uneven garage floor is not only about looks. Cracks and low spots can be a tripping hazard and can let water collect. Lifting the slab helps make the garage safer and helps protect the concrete you already have.

Because slab lifting raises the existing slab, it avoids tearing out and replacing the floor.

How Much Does Garage Floor Leveling Cost?

The garage floor leveling cost depends on how much of the floor needs lifting, how far the slab has sunk and what is under it. Your free inspection gives you a written estimate, and our cost calculator gives a ballpark figure first.

Can You Level a Garage Floor Yourself?

Hardware stores sell self leveling mixes for garage floors, but slab lifting itself takes equipment most homeowners do not have.

A DIY topping covers the surface only. It does not fill the gaps under the concrete, so the slab can keep sinking.

A professional team can lift the slab and look for the cause of the settling at the same time.

How Do You Level Uneven Concrete Slabs Safely?

Leveling an uneven slab starts with an inspection. The inspector looks at the whole area, checks for signs of soil movement and recommends the lifting approach that fits. After the work, the garage is ready for use again once the crew says the patched holes have set.

What About Garage Floor Crack Repair?

Cracks are often the first sign of a sinking slab, so crack repair often goes with slab lifting. After the slab is lifted, cracks and joints can be sealed to help keep out water and debris.

Mudjacking: Raising Settled Concrete Back to Level

Cory Parks — Mon, 16 Jun 2025 22:15:07 GMT

Mudjacking is a concrete leveling method that raises a slab which has settled below its original height. A slurry made with cement is pumped through small holes drilled in the surface, and the existing concrete stays in place. The slurry fills the empty space beneath the slab and lifts it back toward level. It is a less disruptive way to restore a settled surface than tearing it out, which is why homeowners often consider it for driveways, sidewalks, walkways, patios, porch slabs, and garage floors.

Mudjacking serves three goals at once: it restores stability so the slab is properly supported again, it removes the trip hazards that form where two sections of concrete no longer sit flush, and it improves the appearance of a surface that has sunk, cracked, or pitched to one side. The reason a slab settles, though, is almost always in the ground beneath it, and that is where the Carolinas matter. Across the Piedmont, from Charlotte to Greensboro and the Triangle, clay soils take on water through wet seasons and contract through dry stretches. That seasonal swing opens voids under slabs poured on top of the clay, and the concrete drops into the space left behind. In the Sandhills near Fayetteville and Pinehurst, sandy soils drain fast and let fine particles wash out, which quietly loosens the support beneath flatwork. In the Upstate and Midlands of South Carolina around Greenville and Columbia, foothill clay combined with heat and humidity drives a similar moisture load.

Mudjacking suits some of these slabs, but it is not the answer for every one. Whether a slab is a good candidate depends on its condition and on what caused the settlement. HydroHelp911 lifts settled concrete with polyurethane foam injection, and this page explains mudjacking so you can compare the two methods. Every concrete leveling visit begins with a free inspection of the slab and the cause of the settlement.

What to Know About Mudjacking and How the Method Works

HydroHelp911 lifts settled slabs with polyurethane foam, and this page explains mudjacking so you can compare the two. Mudjacking fills the voids under a settled slab with a dense, flowable cement slurry, blended from sand, water, and other fine material, that supports the concrete and pushes it back up.

In mudjacking, a pattern of small holes is drilled through the slab and the slurry is pumped through them under pressure. The lift is done in small, controlled increments so the slab rises evenly. At the target height the holes are patched, and the surface sits flush again, with the trip hazards and the pitched, uneven look corrected. To compare, the polyjacking with expanding foam page shows the method HydroHelp911 uses.

Mudjacking does not change the soil behavior that let the slab settle. Where the soil is already weak or washed out, a lighter polyurethane foam adds less load. In active Piedmont clay, in Sandhills sand where fines keep washing out, or where water drains against the slab, the cause may need correcting first, or piers may be needed.

Common Questions About Mudjacking

What Is Mudjacking and How Is It Different From Replacing the Concrete?

Mudjacking is a concrete leveling method that lifts a settled slab back to level by pumping a slurry made with cement through small holes drilled in the surface. The slurry fills the voids beneath the slab and raises it in place. Replacing the concrete means breaking out the existing slab and pouring a new one. For a slab that is structurally sound but has settled, mudjacking is usually less disruptive. If a slab is badly cracked or deteriorated, replacement may make more sense.

What Kinds of Concrete Can Be Mudjacked?

Mudjacking is commonly used on residential flatwork such as driveways, sidewalks, walkways, patios, porch slabs, and garage floors that have settled and become uneven. Whether it is the right fit depends on the condition of the specific slab and what caused the settlement, which an inspection of the slab establishes.

Will Mudjacking Get Rid of the Trip Hazard Where My Walkway Has Lifted?

That is one of the main reasons homeowners ask about it. When one section of a walkway or driveway settles below the next, the lip between them becomes a trip hazard. Mudjacking raises the low section back flush with the rest so the surface is even again, which removes the hazard and improves how the concrete looks. Whether the slab is a candidate for lifting is confirmed first.

How Much Does Mudjacking Cost?

There is no set price for mudjacking, because the cost follows the slab and the soil beneath it. In general, mudjacking cost depends on the size of the slab, how far it has settled, the number of injection points, access to the area, and the soil conditions. HydroHelp911 lifts settled slabs with polyurethane foam, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Does Mudjacking Fix the Reason My Slab Settled?

Not by itself. Mudjacking lifts the slab and fills the void beneath it, but it does not change the deeper soil behavior that caused the settlement. If the cause is something like water draining against the slab or unstable subgrade, it needs to be addressed as part of the plan, and where the ground needs deeper support a structural solution may be needed, so the lift is more likely to hold.

Why Driveways Sink and How Leveling Works

Cory Parks — Sat, 14 Jun 2025 14:17:59 GMT

A driveway that dropped at the apron or dipped in the middle is usually following the soil under it down. This guide explains why driveways settle, how polyurethane leveling lifts a settled slab, and when lifting is not the right fix.

What Is Your Driveway Doing?

Driveway problems usually fall into a few patterns, and the pattern points to the kind of repair that fits.

A Section Dropped as One Piece. A step at the garage or street joint. An intact slab that has settled can usually be lifted back to grade.
A Hollow Sound, Surface Still Level. A drum note underfoot. A void may have formed while the slab still sits at the right height, and filling it supports the slab again.
Cracked Into Loose Pieces. Fragments that rock under the tires. Concrete broken into pieces cannot be lifted as a unit, so lifting is not the right repair for that section.

Why Do Driveways Sink or Become Uneven?

A driveway is one of the first slabs to show soil movement, partly because it carries the weight of vehicles and partly because of where it sits. The most common spot to see it is where the driveway meets the garage or the street, because the transition makes any drop obvious.

In the Piedmont around Charlotte and Greensboro, clay soil under a driveway swells in wet months and shrinks in dry stretches, and over years that cycle opens voids the slab settles into. In the Sandhills near Fayetteville and Pinehurst, sandy soil shifts and drains differently, and around Asheville, runoff from sloped lots can wash the supporting soil out from under the apron.

These are the same conditions behind uneven concrete slabs around the rest of the property, and some driveways also show cracks across the slab as it loses support.

How Does Driveway Leveling Work?

Driveway leveling lifts the settled section back toward its original elevation, and the existing concrete stays in place. Small ports are drilled through the slab, and material is pumped underneath under controlled pressure until the concrete rises evenly and the void below it is filled.

The most common material today is polyurethane foam. Each leveling method is explained on the concrete leveling solutions page.

Because the solid concrete is supported from below again, the soft spot that let the slab sink is filled at the same time. The ports are patched afterward, which is part of why lifting is less disruptive than tearing out and repouring.

When Is Driveway Leveling Not the Right Fix?

Lifting is the right approach when the driveway slab is structurally sound and simply sitting too low. It is not the answer when the concrete is crumbling or broken into multiple pieces, or when the movement traces back to a deeper issue than flatwork settlement.

A slab that is too far gone is not a candidate for lifting, because material pumped under it has nothing sound to hold up. Once a lifted slab is back to grade, sealing the joints and cracks helps limit water working beneath it.

Common Questions About Driveway Leveling

What Causes a Driveway to Sink or Become Uneven?

Almost always the soil beneath it. In the Piedmont, clay soils swell with moisture and shrink as they dry, opening voids the slab settles into. Other causes include fill soil that was never fully compacted when the driveway was poured, and water washing fine particles out of the supporting soil over time, which is common on sloped lots around Asheville. The slab simply follows the ground down, which is why the cause matters as much as the dip.

Can Concrete Leveling Fix a Cracked Driveway?

It depends on the cracking. If the slab has settled but the sections are still intact, lifting it back to grade can close the gap at the joints and remove the trip hazard. If the driveway is broken into many loose pieces or is crumbling, lifting alone will not restore it, and replacing that area may be the better option.

How Long Does Driveway Leveling Last?

A lift holds as long as the slab stays supported, so it depends on what the soil does over time. In areas with active clay movement or ongoing water intrusion, conditions can change, which is why drainage and soil behavior matter as much as the dip in the slab. Addressing the cause is what makes a lift hold.

Which Slabs Around a Home Does HydroHelp911 Level?

HydroHelp911 uses polyurethane foam lifting on sidewalks and walkways, patios and porches, garage floors, pool decks, interior slabs and concrete steps. Each job starts with a free inspection that finds why the slab moved and ends with a written estimate.

Crawl Space Ventilation: Managing Airflow and Humidity Under Your Home

Cory Parks — Thu, 17 Apr 2025 20:30:32 GMT

Crawl space ventilation is the practice of managing the air that moves through the space beneath your floor. Traditionally, the standard approach was passive: open vents cut into the foundation walls were meant to let outside air flow through and carry moisture away. The idea was simple, and in a dry climate it can work. In the humid Carolinas, the reality is more complicated, and that is where an assessment of your specific home matters more than one rule for every home.

The complication is the air itself. Across much of North and South Carolina, outdoor air carries a heavy moisture load for a large part of the year. When warm, humid summer air enters a cooler crawl space through open vents, it does not always dry the space out. It can do the opposite, because moisture condenses on the cooler surfaces it meets, the floor joists, the subfloor, ductwork, and insulation. So a ventilation strategy that looks reasonable on paper can, in our climate, end up adding moisture to the space. Finding out which is happening under a specific home is the first job.

The right airflow strategy also depends on where you are. In the Piedmont around Charlotte, Greensboro, Winston-Salem, and the Triangle, clay soils hold and release moisture through the seasonal wet and dry cycle, feeding ground moisture vapor up into the crawl space. Around Asheville and the mountains, hillside lots, runoff, and heavy rainfall push water toward and under homes. Along the coast near Wilmington, Brunswick County, and Leland, a high water table and saturated, sandy soils keep the ground beneath a home damp, and salt air adds its own corrosion load. In the Sandhills near Fayetteville and Pinehurst, sandier soils drain differently again. In the SC Upstate around Greenville and the Midlands around Columbia, foothill clay paired with long, humid summers loads the air with moisture for months at a time. Each of these conditions changes what ventilation can and cannot accomplish.

HydroHelp911 treats crawl space ventilation as a question to be answered. We start with a free inspection to measure what the air and the soil are actually doing under your home. In a humid Carolina crawl space, controlling moisture at the source through sealing and encapsulation usually gives a more durable result than open vents. With full encapsulation and a dehumidifier, the vents stay closed all the time. We explain what we find in plain terms and recommend the approach that fits your home, even when that means less work.

What to Know About Crawl Space Ventilation and How the Method Works

Ventilation changes the air in the crawl space, and its effect on moisture depends on the air brought in. Passive vents rely on outdoor air moving through on its own. In a dry climate, that air can carry moisture away. In the humid Carolinas, it is often more humid than the air under the home for much of the year, so passive ventilation can add moisture and feed condensation on cooler surfaces.

Moisture in a crawl space typically arrives through one or more paths:

Ground moisture vapor rising from the soil
Humid outdoor air entering through vents and gaps
Condensation where warm, humid air meets cooler surfaces
Liquid water intruding through drainage issues

Moving air does nothing to stop vapor rising from bare soil or water seeping in at the footing, so we find the source first. In many Carolina crawl spaces, the fix is sealing the space against humid air and ground vapor by encapsulating the crawl space. In others, managing water with interior drainage and a sump is the proportionate fix.

Common Questions About Crawl Space Ventilation

Do Open Foundation Vents Actually Keep a Carolina Crawl Space Dry?

Not reliably. Open vents were designed on the assumption that outside air is drier than the air under the home. For much of the year across North and South Carolina, the opposite is true: warm, humid outdoor air entering a cooler crawl space can condense on joists, subfloor, and ductwork and add moisture to the space. Whether vents help or hurt depends on the specific home, which is what we measure during the inspection before recommending anything. With full encapsulation and a dehumidifier, the vents stay closed all the time. In a crawl space that is not encapsulated, the long standing guidance is to leave the vents open in the warm months and closed in the cold months so pipes do not freeze.

Should I Add More Vents to Fix Crawl Space Humidity?

Often, no. Adding outdoor air to a crawl space in a humid climate can introduce more moisture, especially in summer. More importantly, airflow does nothing to stop ground moisture vapor rising from the soil or water entering through a drainage issue. We identify where the moisture is actually coming from first. If the source is humid air and ground vapor, sealing the space is usually more effective than adding vents, and we will explain why in plain terms.

What Is the Difference Between Crawl Space Ventilation and Encapsulation?

Ventilation tries to manage crawl space moisture by moving air through the space. Encapsulation takes the opposite approach: it seals the crawl space against humid outdoor air and ground moisture vapor so the moisture never gets in. In the humid Carolinas, sealing the space at the source is frequently the more durable result, while ventilation can struggle against the outdoor dew point. Which fits your home depends on the moisture source, the soil, and the conditions we find during the inspection.

Why Does My Crawl Space Feel Damp Even Though It Has Vents?

A vented crawl space can stay damp for a few reasons common in the Carolinas. Ground moisture vapor rises continuously from bare or clay soil, the Piedmont seasonal wet and dry cycle and coastal high water tables keep the soil moist, and humid summer air drawn in through the vents condenses on cooler surfaces. Vents move air but do not address those sources. We assess all of them during the inspection so the recommendation matches what is actually causing the dampness.

Can Poor Crawl Space Moisture Control Affect My Floors and Structure?

Persistent moisture in a crawl space can, over time, contribute to issues homeowners notice upstairs, such as cooler or springier floors and a musty smell that drifts into living space, along with damp or sagging insulation below. The point of managing moisture properly is to keep the wood and the space beneath your floor dry and stable. During the inspection we look at the whole picture and recommend the proportionate fix.

How Much Does Crawl Space Ventilation or Moisture Control Cost?

There is no set price, because the cost follows the moisture source. It depends on the size of the crawl space, the source and severity of the moisture, access, the condition of the existing vents and insulation, and whether sealing the vents as part of encapsulation, drainage or a dehumidifier is the right approach. The free inspection finds the source, and you receive a written estimate at no cost before any work is scheduled.

Crawl Space Ventilation: Should Your Vents Be Open or Closed?

Cory Parks — Thu, 17 Apr 2025 20:10:04 GMT

Crawl space ventilation is how air moves in and out of the space under your home, usually through foundation vents. In the humid Carolinas, open vents often let damp outdoor air into a cooler crawl space, where it condenses on ducts and framing. With full encapsulation, the vents stay closed all the time.

What Is Driving the Moisture in Your Vented Crawl Space?

Whether vents help or hurt depends on where the moisture comes from and how the crawl space is built. In a dry climate, outside air can carry moisture away. Across the Piedmont, the coast and the South Carolina Upstate and Midlands, the outside air is humid for much of the year, so open vents often add moisture to a cooler crawl space. Soil vapor and water entering the space need their own repairs.

Humid Summer Air Through Open Vents. Condensation on ducts and framing in warm months. Outdoor air that is more humid than the crawl space condenses on cooler surfaces. Sealing the vents usually helps more than added airflow.
Vapor From Bare Soil. Damp air even with the vents open. Moving air does not stop vapor rising from the soil. A vapor barrier over the ground addresses it.
Water Entering the Crawl Space. Wet soil or standing water after rain. Airflow does not remove water. Interior drainage and a sump pump handle liquid water.
A Localized Airflow Problem. One damp area in a crawl space that is otherwise dry. One damp corner in an otherwise dry crawl space often has a local cause, such as a blocked vent or a plumbing leak. The inspection finds it before anything changes.

Should a Carolina Crawl Space Be Vented or Sealed?

Crawl space ventilation is one of the most misunderstood topics in home moisture. For decades, homes were built with open foundation vents on the idea that outdoor air would carry moisture away. Across the Piedmont, the coast, and the SC Upstate and Midlands, outdoor air is humid for much of the year, so when warm, moist air flows into a cooler crawl space it can condense on the framing, ducts, and pipes and add moisture.

That is why ventilation is assessed for your climate and crawl space. Persistent dampness under the floor and heating and cooling bills creeping up are two common results of open vents in humid weather.

Should Crawl Space Vents Be Open or Closed in Summer and Winter?

With full encapsulation, the vents stay closed all the time. The ground is covered, the space is sealed, and a dehumidifier controls the air, so there is no reason to let outside air in.

Without encapsulation, the older rule is to open the vents in the warmer months and close them in the colder months so pipes do not freeze. Winter air is drier, so closing the vents then is less of a concern, although humidity under the house can still lead to wood rot and mold. Our recommendation for a damp crawl space is to encapsulate it and add a dehumidifier.

Vents at a Glance

Encapsulated crawl space: vents closed all year
Vented crawl space in warm months: often opened
Vented crawl space in cold months: closed so pipes do not freeze

What Are the Signs Your Crawl Space Vents Are Adding Moisture?

The signs usually peak in summer. Ducts and pipes sweat, the subfloor feels damp, insulation sags near the vents, and a musty smell drifts into the house on humid days. Insulation falling from the joists near a vent is a common finding.

In winter, open vents show up as cold floors and drafts in the rooms above, and pipes near the vents are more likely to freeze. Broken vent screens that let leaves and small animals in are another sign the openings need attention.

How Do You Control Crawl Space Moisture Without Venting?

The approach that controls moisture best in our climate is usually to seal the crawl space, then condition the air inside. That means closing off the foundation vents with sealed foundation vent covers, installing a vapor barrier to stop ground moisture, and managing the remaining humidity with a dehumidifier and controlled air circulation, so the crawl space becomes a dry, stable space.

The guide to crawl space airflow explains when moving air helps and when it adds moisture, and encapsulating the crawl space covers the sealed approach.

What Are Crawl Space Vent Covers?

A vent cover is a fitted panel sealed over a foundation vent, so outside air stops flowing through it. Vent covers are part of closing off a crawl space, along with a liner over the soil and a sealed access door.

Engineered flood vents in some coastal homes are built to let floodwater pass during a flood and must stay functional, so they are never covered. We identify which openings are which during the inspection.

Is Crawl Space Ventilation Required by Code?

Requirements vary, and modern codes increasingly recognize sealed, conditioned crawl spaces as an alternative to open venting, often with specific conditions attached. We factor the code considerations for your area into the recommendation.

Because the right answer depends on the home, a crawl space inspection is meant to settle it. We look at the existing vents, the moisture sources, the condition of the framing, and any condensation already forming, then explain whether sealing and conditioning or another approach fits, and why.

What Does Crawl Space Ventilation Work Cost?

Vent covers and sealing are part of crawl space encapsulation, so the cost follows the encapsulation plan. The number of vents, the size of the crawl space, and the moisture work involved all change the estimate. You receive a written estimate after a free inspection, and financing is available.

Sealing, Vent Covers, or Airflow: Which Fits Your Crawl Space?

Sealing and Encapsulation fits when humid outdoor air or ground vapor is driving the moisture, as it often is in the Carolinas. It is not the fit when water is actively flowing in. Drainage comes first so the space is dry before it is sealed.
Vent Covers fits when the vents are being closed as part of sealing the space. It is not the fit when the openings are engineered flood vents in a coastal flood zone. Those stay functional.
Dehumidifier in a Sealed Crawl Space fits when the vents are sealed and the ground is covered, and the air still holds moisture. It is not the fit when the vents are open. The unit would be drying outside air.

Common Questions About Crawl Space Ventilation

Should a Crawl Space Be Vented or Sealed?

In the humid Carolinas, sealing and conditioning a crawl space usually controls moisture better than venting it, because humid outdoor air often condenses inside a cooler crawl space. With full encapsulation and a dehumidifier, the vents stay closed all the time. In a crawl space that is not encapsulated, the long standing guidance is to open the vents in warm months and close them in cold months so pipes do not freeze.

How Does Ventilation Affect Crawl Space Moisture?

Ventilation can either help or hurt depending on the climate. In a dry climate, airflow can carry moisture out. In the humid Carolinas, drawing in warm, moist outdoor air through open vents frequently raises crawl space moisture, because that air condenses on the cooler framing, ducts, and pipes. That is why controlling the air, often by sealing the space, tends to outperform passive venting here.

Can Poor Ventilation Cause Mold Growth in a Crawl Space?

Moisture is what allows mold to grow, and a ventilation approach that keeps the framing damp, such as open vents pulling in humid Carolina air, creates exactly those conditions. Controlling the moisture, often by sealing and conditioning the space, removes that driver.

How Do You Improve Crawl Space Airflow and Air Conditions?

In the humid Carolinas, the approach that usually keeps a crawl space dry is to seal it: close the vents, cover the ground with a liner, and control the humidity with a dehumidifier. The inspection determines what a particular crawl space needs.

Is Crawl Space Ventilation Required by Code?

Requirements vary, and modern codes increasingly recognize sealed, conditioned crawl spaces as an alternative to traditional open venting, often with specific conditions attached. Because local requirements differ and change over time, we factor applicable code considerations into our recommendation for your area. The inspection is where we sort out what applies to your specific home.

What Does Crawl Space Ventilation Work Cost?

The cost depends on what the crawl space needs, most often sealing the vents as part of encapsulation. The size of the crawl space, the number of vents, and whether a liner or dehumidifier is part of the plan all change it. You receive a written estimate after a free inspection, at no cost.

Micro Piles: How Drilled Piles Carry a Foundation to Firmer Soil

Cory Parks — Thu, 17 Apr 2025 20:03:48 GMT

A micro pile, sometimes called a mini pile or pin pile, is a narrow pile made from a steel casing or threaded steel bar set in grout inside a drilled hole. It carries the weight of a structure down through weak upper soil to firmer soil or rock below. Because the piles are narrow, the drilling rigs that install them are compact, which is why micro piles come up for tight spaces such as narrow side yards, basement interiors and lots close to neighboring buildings.

Foundation settlement in the Carolinas usually starts with the soil under the footing. Across the Piedmont, clay soils swell when wet and shrink when dry, and that seasonal movement can let a footing drop. In the Sandhills and along the coastal plain, sandy soils can wash out or compress under load. On mountain lots, fill soil and slopes can settle unevenly. Whichever method carries the load, the goal is to reach soil below the layer that is moving.

HydroHelp911 supports settled foundations with helical piers and push piers, and this page explains micro piles so you can compare them. Every foundation repair starts with a free inspection that measures the settlement and looks at the soil and water around the home.

What to Know About Micro Piles and How the Method Works

HydroHelp911 underpins settled foundations with helical piers and push piers, and this page explains micro piles so you can compare them. A micro pile starts with a hole drilled through the weak soil, often with a compact rig.

A steel casing or bar goes into the hole, and grout fills the space around it so the pile bonds with the soil or rock along its length. A bracket ties the foundation to the top of the pile, and the load of the home moves onto it. Helical and push piers reach firmer soil without drilling or grout: a helical pier is screwed in, and a push pier is pressed down using the weight of the home.

No pier or pile changes the soil behavior that let a footing settle in the first place. Signs such as a foundation sinking at one corner or stair step cracks in brick point to the cause, and the inspection looks at how water reaches the soil as well as how far the home has moved.

Common Questions About Micro Piles

What Is the Difference Between Micro Piles and Helical or Push Piers?

All three carry the weight of a home down to firmer soil. A micro pile is drilled and grouted in place. A helical pier is a steel shaft with helical plates that is screwed into the ground, and a push pier is a steel pipe pressed down hydraulically using the weight of the home. HydroHelp911 installs helical piers and push piers, and the inspection shows which of the two fits your home and soil.

Why Are Micro Piles Used in Tight Spaces?

The piles are narrow, so the drilling equipment that installs them is compact and can work in places a larger rig cannot reach, such as basement interiors, narrow side yards and lots close to other buildings. The inspection looks at access around your home when it plans a pier layout.

Why Do Foundations Settle in the Carolinas?

Most settlement starts with the soil. Piedmont clay swells in wet seasons and shrinks in dry ones, and over the years that movement can let a footing drop. Sandy soils in the Sandhills and on the coastal plain can wash out or compress, and fill soil on hillside lots can settle unevenly. Water draining toward the foundation adds to each of these, which is why the inspection looks at drainage as well as the settlement.

Can a Pile Lift My Foundation Back to Level?

Sometimes part of the way. Once a pier or pile carries the load, part of the settlement can often be recovered, but how much depends on the structure and how long it has sat out of level. The main goal of any pier or pile is to stop further settlement in the area it supports. The inspection measures how far the home has moved and explains what to expect.

How Much Do Micro Piles Cost?

There is no set price for micro piles, because the cost follows the depth to firmer soil, the number of piles, access and the load of the home. HydroHelp911 supports settled foundations with helical piers and push piers, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Concrete Piers: How Pressed and Poured Piers Support a Foundation

Cory Parks — Thu, 17 Apr 2025 20:02:50 GMT

Concrete piers are concrete columns placed in the ground beneath a foundation to carry its weight down to firmer soil. They are built two main ways. Poured piers are formed and filled with concrete in place, and pressed piers are short precast concrete cylinders stacked and pressed into the ground one on top of another under the footing. Either way, the column reaches below the weak soil the footing sits on, and a cap ties the foundation to it.

In the Carolinas, the soil under a footing is usually what moves. Piedmont clay swells in wet seasons and shrinks in dry ones, which can let a footing drop over the years. Sandy soils in the Sandhills and on the coast can compress or wash out, and fill soil on hillside lots in the mountains can settle unevenly. The depth to firmer soil varies from one lot to the next, which shapes any pier plan.

HydroHelp911 supports settled foundations with steel helical piers and push piers, and this page explains concrete piers so you can compare them. Every foundation repair starts with a free inspection of the settlement and of the soil and water around the home.

What to Know About Concrete Piers and How the Method Works

HydroHelp911 uses steel helical piers and push piers, and this page explains concrete piers so you can compare them. A pressed concrete pier is built from short precast cylinders set one on top of another and pressed down beneath the footing until the column resists further movement.

A poured pier is formed in a hole and filled with concrete in place. Pressed piers go only as deep as the column can be pushed, which in dense clay can be shallower than steel piers reach. Steel push piers are driven in sections until the soil holds the load, and helical piers are turned in until they reach a measured capacity.

No pier changes the soil behavior that let the footing settle. Signs such as a foundation settling unevenly or cracks running through exterior brick point to the cause, and the inspection also looks at how water reaches the soil.

Common Questions About Concrete Piers

What Is the Difference Between Concrete Piers and Steel Piers?

Both carry the weight of a home down to firmer soil. Concrete piers are columns of precast cylinders pressed into the ground or concrete poured in place. Steel piers are steel shafts: helical piers are screwed into the ground, and push piers are driven down hydraulically using the weight of the home. HydroHelp911 installs helical piers and push piers, and the inspection shows which one fits your home.

Will Piers Bring a Settled Foundation Back to Level?

Sometimes part of the way. Once piers carry the load, part of the settlement can often be recovered, but how much depends on the structure and how long it has sat out of level. The main goal of any pier is to stop further settlement in the area it supports. The inspection measures how far the home has moved and explains what to expect.

Why Does the Soil Under a Footing Move?

In the Piedmont, clay soils swell when they take on water and shrink as they dry, and that cycle can let a footing drop over the years. In the Sandhills and along the coast, sandy soils can compress or wash out. On hillside lots, fill soil can settle unevenly. Water draining toward the foundation makes each of these worse, so the inspection looks at drainage too.

How Much Do Concrete Piers Cost?

There is no set price for concrete piers, because the cost follows the number of piers, the depth to firmer soil and access to the footing. HydroHelp911 supports settled foundations with helical piers and push piers, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Which Foundation Piers Does HydroHelp911 Install?

HydroHelp911 installs steel helical piers and push piers for settled foundations, and slab piers for homes built on a concrete slab. Which one fits depends on the load, the soil and access around the home, which the free inspection works out before any plan is written.

Tieback Anchors: How They Hold a Bowing Wall Against the Soil Behind It

Cory Parks — Thu, 17 Apr 2025 20:00:19 GMT

A tieback anchor is a steel anchor that holds a bowing, leaning or tilting wall against the soil pushing on it. It reaches back through the wall into firmer soil beyond the soil that is pressing in, and a plate on the inside face ties the wall to it. A helical tieback is one common type: a steel shaft with helical plates, shaped like a screw, turned into the ground at an angle. Homeowners often come across tiebacks while reading about bowing basement walls.

The sideways pressure behind a bowing wall usually comes from soil and water. Across the Piedmont, from Greensboro and Winston-Salem to the Triangle, clay soils take on water in wet seasons and swell, then shrink in dry spells, and that repeated cycle presses on basement walls. On mountain lots around Asheville, slopes and heavy rain soak the soil against a wall. In the SC Upstate and Midlands, foothill clay and summer storms load walls in much the same way.

HydroHelp911 stabilizes bowing walls with wall anchors, I-beam wall bracing and carbon fiber reinforcement, and this page explains tiebacks so you can compare them with those methods. Every wall repair starts with a free inspection that measures how far the wall has moved and looks at what is pushing on it.

What to Know About Tieback Anchors / Helical Tiebacks and How the Method Works

HydroHelp911 stabilizes bowing walls with wall anchors set in the yard, steel I-beam braces and carbon fiber, and this page explains tiebacks so you can compare them. A tieback counters sideways pressure: the soil right behind the wall pushes harder than the wall can hold, so the anchor reaches past that soil to firmer ground.

With a helical tieback, the shaft is turned into the soil at an angle from inside the wall until it reaches the holding capacity the design calls for. It connects to a steel plate on the inside face, and tightening the connection holds the wall against the load. A wall anchor with a buried plate does a similar job, and steel I-beams set against the wall hold it from inside without reaching into the soil.

Any anchor or brace is meant to stabilize a basement wall bowing inward against further movement, and none of them straightens the wall. None of them removes the water that adds to the pressure either, which can show up as wide cracks with water seeping through, so the inspection also looks at how water reaches the wall.

Common Questions About Tieback Anchors / Helical Tiebacks

What Is a Tieback Anchor and How Is It Different From a Wall Anchor?

A tieback anchor ties a wall to firmer soil beyond the soil pushing on it, using a steel anchor that extends back through the wall. A helical tieback is turned into the ground like a screw. A wall anchor works on a similar idea but uses an anchor plate buried in the yard, connected by a steel rod to a plate on the inside of the wall. HydroHelp911 stabilizes bowing walls with wall anchors, I-beam wall bracing and carbon fiber reinforcement, and the inspection shows which of those fits your wall.

Which Bowing Wall Repairs Does HydroHelp911 Install?

HydroHelp911 installs wall anchors, I-beam wall bracing and carbon fiber reinforcement for bowing and leaning basement walls. Carbon fiber straps often suit early, minor bowing. Wall anchors and I-beam braces suit walls under heavier pressure. If the wall is cracking because the footing below has settled, piers may be part of the plan. The free inspection measures how far the wall has moved and what is driving it.

Can Tieback Anchors Straighten a Wall That Is Already Bowing?

Tiebacks, like wall anchors, are used to stabilize a wall, which means holding it against further inward movement. They are not a method for straightening a wall. The same is true of the wall anchors HydroHelp911 installs: they stabilize a wall and do not straighten it.

Do Tieback Anchors Fix the Water Pressure Behind the Wall?

Not by themselves. An anchor holds the wall against the load, but it does not remove the water in the soil that adds to that load. In the Carolinas, much of that pressure comes from water, whether rain soaking a slope near Asheville or Piedmont clay swelling after a wet stretch. For a basement wall, an interior drainage system may be part of the conversation at the inspection.

How Much Do Tieback Anchors Cost?

There is no set price for tieback anchors, because the cost follows the wall, the soil behind it and how far the wall has moved. In general, the number of anchors, how deep each must reach and access to the wall shape the cost of any wall anchoring system. HydroHelp911 stabilizes bowing walls with wall anchors, I-beam wall bracing and carbon fiber, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Slab & Mud Jacking: Lifting Sunken Concrete Back Into Place

Cory Parks — Thu, 17 Apr 2025 19:40:51 GMT

Mud jacking, sometimes called slab jacking or concrete lifting, is a method for raising a concrete slab that has settled below its original height. A slurry made with cement is pumped through small holes drilled into the surface, filling the empty space underneath and lifting the slab back toward level, and the existing slab stays in place. It is often one of the less disruptive options for settled driveways, sidewalks, patios, garage floors, and porch slabs.

In the Carolinas, settled concrete usually traces back to what is happening in the soil beneath the slab. In the Piedmont, including Charlotte, Greensboro, Winston-Salem, and the Triangle, clay soils absorb water during wet seasons and shrink during dry spells, and that repeated swelling and shrinking can open gaps beneath slabs poured on top of it. In the Sandhills around Fayetteville and Pinehurst, sandy soils drain and shift differently, so a slab can settle as fine particles wash out and the support beneath it loosens. Fill soil that was not packed well when the slab was poured, and water that runs along the edge of a slab, can also wear away support.

Mud jacking suits some of these slabs, but not all of them. Whether a slab is a good candidate depends on its condition and on what is causing the settling. HydroHelp911 lifts settled concrete with polyurethane foam injection, and this page explains mud jacking so you can compare the two methods. Every concrete leveling visit starts with a free inspection of the slab and the cause of the settling.

What to Know About Slab and Mud Jacking and How the Method Works

HydroHelp911 lifts settled slabs with polyurethane foam, and this page explains mud jacking so you can compare the two. Mud jacking fills the empty space under a settled slab with a dense, flowing slurry of sand, cement, and water that supports the slab and pushes it back up.

Small holes are drilled through the concrete and the slurry is pumped through them under pressure, raising the slab in small steps toward its original height. At the target height the holes are patched, and the cured slurry acts as a base beneath the concrete. Lifting a slab this way can help with a garage floor that cracked and dropped. To compare, the polyjacking with expanding foam page shows the method HydroHelp911 uses.

Mud jacking addresses the slab and the space under it. It does not change the deeper soil or how water reaches the slab, which may be what let it settle, so diagnosis matters. Beneath some slabs sits active Piedmont clay that keeps moving. Around others, the inspection finds water collecting along the slab edge. Then a deeper repair, such as steel piers under a slab foundation, may be needed.

Common Questions About Slab & Mud Jacking

What Is the Difference Between Mud Jacking and Slab Jacking?

The terms are often used the same way. "Slab jacking" and "concrete lifting" are general terms for raising a settled slab back to level. "Mud jacking" usually means doing that with a slurry made with cement pumped beneath the slab. Concrete can also be lifted with polyurethane foam, which is a different material. Which approach fits depends on the slab and the soil beneath it.

Mud Jacking vs Polyurethane Foam: Which Is Better for Lifting Concrete?

Neither is better for every slab. A cement slurry is a heavier, denser fill. Polyurethane foam is lighter, resists water, and adds less weight to the soil beneath the slab, which can matter where that soil is weak. The slurry's weight can help on some slabs and work against it on others. The slab, the soil, and the access decide which material fits. HydroHelp911 lifts slabs with polyurethane foam injection.

Can Mud Jacking Be Used on Driveways, Sidewalks, and Patios?

Yes. Mud jacking is commonly used on home driveways, sidewalks, walkways, patios, porch slabs, and garage floors that have settled and become uneven. Whether it is the right fit depends on the condition of the slab and what caused the settling, which an inspection of the slab establishes.

Is Mud Jacking Less Disruptive Than Replacing the Concrete?

Often, yes. Mud jacking lifts the existing slab in place by drilling small holes and pumping slurry underneath, so the old concrete stays where it is. For a slab that is still sound but has settled, that usually means less demolition. If a slab is badly cracked or worn, replacement may make more sense.

How Much Does Mud Jacking Cost?

There is no set price for mud jacking, because the cost follows the slab and the soil beneath it. In general, mud jacking cost depends on the size of the slab, how far it has settled, how many injection points are needed, and access to the area. HydroHelp911 lifts settled slabs with polyurethane foam, and the free inspection ends with a written estimate at no cost before any work is scheduled.

Will Mud Jacking Fix the Reason My Slab Settled?

Not by itself. Mud jacking lifts the slab and fills the space beneath it, but it does not change deeper soil behavior or how water reaches the slab. Where the soil below is the problem, a deeper structural repair such as piers may be needed so the result is more likely to hold.

How to Prevent Your House From Shifting

Cory Parks — Mon, 21 Oct 2024 03:21:10 GMT

To help prevent your house from shifting, keep water away from the foundation, control moisture in the crawl space and watch for early signs such as new cracks or sticking doors. Foundations shift when the soil under them moves, and when a foundation has already shifted, piers or crawl space supports are the usual repair.

This article covers why foundations shift, the signs to watch for, ways to help prevent it and the role of foundation repairs.

What Does It Mean When Foundations Shift?

Foundation shifting happens when the ground beneath your home moves. This movement can be caused by soil settling, extreme weather changes, or tree roots growing too close to your house. Over time, these shifts can lead to cracks in your walls, uneven floors, and doors or windows that won’t close properly. These are common signs to watch for.

Uniform Settlement

Uniform settlement happens when your home’s foundation sinks evenly into the ground. When it takes place, your whole house settles down smoothly. It might not cause as many cracks or uneven floors as the other type of settlement, but it can still lead to problems like drainage issues or the house sitting too low.

Differential Settlement

Differential settlement happens when different parts of the foundation sink at different rates. It can lead to more serious problems, including cracks in the walls, uneven floors and misaligned doors and windows, and when the cause is not addressed those problems can grow.

Why Do Foundations Shift?

Foundation shifts occur when the ground beneath your home moves; here are some potential causes:

Soil Conditions: One of the main reasons foundations shift is the soil under them. In the Carolina Piedmont, clay rich soil swells when it is wet and shrinks when it is dry, which can push on the foundation and leave gaps under it. On the coast, sandy soil and a high water table are the bigger factors.
Poor Drainage: Water can pool near the foundation if the yard does not drain well, and saturated soil supports a foundation less well. Gutters and downspouts that carry roof water away from the house help; they are homeowner maintenance.
Weather Changes: Heavy rain, drought and extreme heat can change the soil, which can lead to shifting. It is worth checking the foundation after big weather events.

What Are the Signs of Foundation Movement?

Foundation movement can cause problems in your home. Here are some common signs to look out for:

Cracks in Walls and Floors: One of the first signs of foundation movement is cracks in your walls or floors. You may notice small cracks in drywall or larger cracks in brick and masonry. Horizontal cracks are often the more concerning kind.
Sloping or Uneven Floors: Uneven or sagging floors can be one of your home’s most noticeable indicators of foundation issues. A floor where a ball rolls toward one side can mean the foundation or the support under the floor has moved.
Sticking Doors and Windows: It may be due to a shifting foundation if doors and windows are difficult to open or close. It happens because the frames may become warped as the foundation moves. Check for gaps around the frames, as they may indicate foundation problems.
Bowed or Leaning Walls: If your basement walls are bulging or curved, this could indicate significant foundation movement. As the walls bow or lean further, they can weaken, which may affect the overall stability of your home.
Foundation Displacement: When certain areas of your home appear to sink lower or rise higher than others, it may be a clear signal of foundation displacement. This unevenness can indicate potential issues with the foundation.

How Can You Help Prevent Foundation Movement?

These steps help:

Homeowner tip, gutters and downspouts: Clean, working gutters and downspouts that carry water away from the house help keep the soil around the foundation from soaking.
Check for leaks: Leaking pipes can soak the soil around your home, which can contribute to shifting. Damp spots on floors or walls can be a sign of a leak, and leaks can also lead to mold.
Encapsulation (vapor barrier installation): Sealing your crawl space with a vapor barrier as part of encapsulation helps keep ground moisture out of the crawl space and lowers humidity, which helps protect the wood framing and the air in your home.
Crawl space supports: Adjustable screw jacks in your crawl space give the floor framing solid points of support and help keep sagging floors from getting worse.
Regular checks: Look over your home inside and out for cracks in walls and doors or windows that stick. Noticing changes early helps.

How Is a Shifting Foundation Repaired?

These repair methods help stabilize a foundation that has shifted:

Pier Installation: Pier installation is a method used to support and stabilize a foundation. Professionals install sturdy columns, called piers (helical or push), which are long, strong supports, into the ground beneath your foundation. These piers go deep enough to reach solid soil or bedrock, where they can hold up the weight of your home.
Crawl Space Support: Crawl space support includes various tools and components to hold up the floors in homes with crawl spaces. These supports help maintain the stability and structure of your home by preventing sagging or uneven floors. Crawl space support uses steel, wood or concrete support posts installed in the crawl space to carry the weight of the house down to the ground and help keep the floors above level.
Wall Anchors stabilize walls that are bowing or cracking from soil or water pressure. They are anchored in firm soil outside the wall and help stabilize it against further inward movement; they do not straighten it.
Concrete lifting: Sunken concrete slabs can be lifted back toward level with polyurethane foam injection.

What Are Basement Weep Holes?

Cory Parks — Tue, 01 Oct 2024 09:00:17 GMT

Basement weep holes are small yet essential features in the construction of a home’s foundation. If you’ve ever noticed tiny holes drilled into the bottom of your basement walls, you’ve likely spotted weep holes.

Weep holes let water that collects inside a concrete block wall drain out, which relieves water pressure on the wall. This article covers what they are, how they work and how they help with water problems that can lead to basement repairs.

What Are Basement Weep Holes?

Weep holes are small openings or gaps in the basement walls that are drilled to allow water to escape from where it is most likely to accumulate. Think of weep holes like the drainage holes in a flower pot. Just like those holes let excess water escape to keep the plant’s roots from rotting, basement weep holes let water drain away to protect your walls and foundation.

Benefits of Basement Weep Holes

Weep holes are a simple but effective solution to many common basement problems.

Here are some of their benefits:

Water Drainage: Weep holes help in protecting your basement walls from water damage. When it rains, water can collect behind or inside the walls, and when the cause is not addressed it can lead to leaks, mold and damage to the wall. Weep holes give that trapped water a way out.
Prevention of Mold and Mildew: Standing water and persistent moisture create an ideal environment for mold and mildew to thrive. This can affect not only your basement’s structural components but also your home’s indoor air quality. Weep holes let water escape, which can help with lowering levels of humidity and the chance of mold and mildew.
Reduced Pressure on Walls: Water pressure can build up behind your walls, especially during heavy rains or poor drainage around your home. Over time, this water pressure can lead to cracks, leaks and bowing. Weep holes help relieve this pressure by letting water escape.
Protecting Building Materials: Constant moisture can wear down concrete, wood and insulation. Managing water through weep holes helps protect these materials.

What Are the Signs Your Basement Needs Weep Holes?

If you have been dealing with dampness, leaks or minor flooding in your basement, the cause may be more than a leaky pipe. Water collecting inside the walls is one possibility. These signs can point to it:

Visible Water Damage: If you notice any stains, peeling paint, or bubbling drywall on your basement walls, it may be a sign of water damage. These issues often point to water seeping in from the outside. Weep holes, usually paired with interior drainage, can give that water a controlled path out.
Frequent Moisture or Damp Conditions: A consistently damp basement might mean water is finding its way inside. That moisture can lead to mold and mildew. Weep holes can help by letting water drain out of the walls.
Cracks in Walls or Floor: The presence of cracks in your basement walls or floors might seem minor, but they’re often an early sign of potential water issues. These wall or floor cracks can let water seep through. Weep holes can help by giving water a controlled path out of the wall.
Efflorescence: Efflorescence shows up as a white, powdery residue on your basement walls. It’s a sign of water evaporation leaving behind salt deposits and indicates that your basement walls are absorbing moisture. Installing weep holes can help reduce such water accumulation issues.

How Do Basement Weep Holes Work?

During rainy weather or when the ground is soaked, water may penetrate the walls of your basement. If your foundation is constructed with hollow concrete masonry units (CMUs), water has the potential to fill the voids inside these blocks. Water accumulation inside the blocks generates hydrostatic pressure, exerting force against the walls. Weep holes let that water drain out of the blocks, which reduces the pressure on the wall. Paired with an interior drainage system, the water is then carried to a sump.

What Are the Alternatives to Basement Weep Holes?

Basement Waterproofing

Interior basement waterproofing helps keep a basement dry. It manages the water that reaches the basement and removes water that gets in, which helps prevent mold, mildew and damage from moisture.

Interior French Drain Installation

An interior French drain installation runs along the inside of the foundation wall, under the floor. A channel is cut, filled with gravel and fitted with a perforated pipe that collects water and carries it to a sump pump. It is a common way to manage water that reaches a basement or crawl space.

Sump Pump Installation

A sump pump helps keep a basement or crawl space dry. Water collects in a sump basin, usually at the lowest point, and when it reaches a set level the pump turns on and sends the water out of the house. This helps prevent standing water and the moisture problems that come with it.

How Do You Maintain Basement Weep Holes?

Weep holes work only while they stay open. These steps help:

Regular Inspections: Periodically check your basement weep holes to ensure they aren’t blocked. Be on the lookout for dirt, debris, or plant growth that might obstruct water flow.
Cleaning: If you find any blockages, clear them to keep the drainage functioning correctly. Routine cleaning allows water to escape freely, helping to prevent water buildup.
Repairing Damage: Inspect the area around your basement weep holes for cracks or damage. Addressing them helps keep water from seeping into your basement.
Ask a Professional: If you are unsure about the condition of your weep holes, or water problems keep coming back, a professional inspection can help.

Who Can Check Your Basement for Water Problems?

If you have noticed moisture or leaks in your basement, an inspection can show where the water comes from and what would help. HydroHelp911 serves homeowners across North and South Carolina with interior basement waterproofing.

How Long Does It Take for a House to Settle?

Cory Parks — Fri, 20 Sep 2024 09:00:37 GMT

There is no fixed settlement period for a house. Much of a new house's settling often happens in its first year or two, as it goes through its first seasons of wet and dry soil, but homes can keep settling slightly for years. Even settling is normal; settling that is uneven, or that keeps cracking walls and sticking doors, is worth an inspection.

If your home is newly built, you have probably heard it will settle over time. This article covers what that means, how long it can take and when settling is a problem.

What Is House Settlement?

According to Forensic Engineers Inc., settlement is the downward movement of soil under the weight of a structure, such as a house. Some settling is a normal process for homes, especially new ones.

When it happens unevenly, though, it can cause problems that need foundation repair.

What Is the Difference Between Normal and Differential Settlement?

Normal settlement is the even sinking of a house as it adjusts to the soil it sits on. It happens gradually and evenly across the structure, and it typically does not affect the house's structure. Watching for changes over time is usually enough, with minor repairs as needed.

Differential settlement happens when different parts of the house settle at different rates. This uneven settling can lead to structural problems, and it often goes with poor soil compaction, changes in soil moisture or poor drainage.

If your house shows signs of differential settlement, a foundation specialist can assess it and recommend a repair, such as underpinning, interior drainage or soil stabilization.

How Long Does It Take for a House to Settle?

How long a house takes to settle varies. Much of a new house's settling often happens in the first year or two, as it goes through changing seasons, temperatures and soil movement.

Settling is not always limited to those first years. Homes can keep settling slightly over time, and there is no standard timeline for when a house stops settling.

What Causes a House to Settle?

House settling is common as a building adjusts to the ground under it. Several factors can cause or add to it:

Soil Condition

Different soils carry weight differently. Sand and gravel generally hold up a load better than silt and clay. In the Carolina Piedmont, many homes sit on clay rich soil; on the coast, sandy soil and a high water table are more common. So, depending on the soil where you live, a house may settle more or less.

If the soil was not compacted well before construction, the ground can also settle after the house is built.

Weight of the House

The weight of the house, including additions and changes over the years, presses on the foundation and the soil under it. On soil that was not compacted well, or that carries less weight, that load can lead to settling.

Moisture Content

Changes in soil moisture can make soil expand when wet and shrink when dry. This is especially true of clay soils. Poor drainage or grading can let water collect around the house, which can make the soil swell or wash away.

Seasonal Changes

Each season brings different moisture levels. Heavy spring rain can make soil expand, and dry summer weather can make it shrink.

In colder areas and higher elevations, the ground can freeze and thaw. Water expands when it freezes, which can move the soil or the foundation.

Construction Methods

Poor construction, such as a poorly built foundation, can lead to uneven settling. A foundation that is designed and built for its soil helps limit settling problems.

Tree Roots and Vegetation

Large trees near the house can pull a lot of moisture from the soil, which can make it shrink and settle. Roots can also push soil aside, and removing large trees can change the soil's moisture too.

Flooding and Heavy Rain

Floods and heavy rain can saturate the soil, which can weaken its support of the house and wash soil away.

Nearby Construction

Construction near your home can cause vibrations that move soil. Digging nearby can also change the soil under your house.

What Are the Signs of House Settlement?

These signs can mean your house is settling:

Small, thin cracks in walls or ceilings
Minor cracks in the foundation
Gaps around windows, doors or trim
Cracks in brick, drywall or other surfaces
Gaps where wood joints are coming apart
Gaps between cabinets and walls
Uneven or tilted floors
Water collecting in the basement
Pipes that break as the house shifts
Sagging or gaps in the roofline

How Is House Settling Repaired?

Monitoring Minor Settling

Some settling is minor. Keeping a log of what you see, such as the size of a crack or a door that starts to stick, helps you notice changes, and an inspection can tell you whether it needs repair.

When the signs are getting worse, these are common repairs.

Steel Push Piers

Steel push piers are steel pipes driven deep into the ground beneath a foundation to reach stable soil or rock. They are used to stabilize, and in many cases lift back toward level, the parts of a building that have settled unevenly. The piers are driven hydraulically through the weak soil until they reach a depth that provides support.

Helical Piers

Helical piers, or screw piles, are steel shafts with plates shaped like a screw that are turned into the ground. Like push piers, they are used to stabilize and lift structures. The helix plates spread the load, and helical piers work well where heavy equipment access is limited, where soils carry less weight and where the water table is high.

When Should You Call a Foundation Professional?

Contact HydroHelp911 if you notice:

Large or uneven cracks in your foundation or walls

Is a Crawl Space Vapor Barrier Necessary?

Cory Parks — Fri, 13 Sep 2024 09:00:55 GMT

A crawl space vapor barrier is often worth having, especially in a humid climate or a crawl space that takes on ground moisture. Whether a barrier alone is enough depends on where the moisture comes from and how much there is; some crawl spaces need full encapsulation, drainage or a dehumidifier as well.

This article covers the moisture problems a vapor barrier helps with, how it is installed and the other moisture control options.

What Is a Crawl Space Vapor Barrier?

A vapor or moisture barrier is a polyethylene plastic sheet installed on the floor of a crawl space to prevent moisture from the ground from migrating into the space. This barrier acts as a moisture control solution by blocking the natural moisture that evaporates from the ground, reducing humidity levels within the crawl space. Installing a vapor barrier typically involves covering the entire ground surface and securing it to ensure it stays in place.

Crawl Space Encapsulation vs. Vapor Barrier

Crawl space encapsulation and vapor barrier installation both control moisture. They differ in how much of the crawl space they cover.

Vapor Barrier: This involves laying polyethylene sheeting on the ground of the crawl space and overlapping the sheets at the seams. It is typically 6 to 10 mil thick, is not taped, and does not run up the walls or piers. It provides a layer of protection against ground moisture. It is a simpler installation than encapsulation and covers less of the crawl space.
Crawl Space Encapsulation: This is a more extensive crawl space solution that includes covering the ground, foundation walls, and piers with a thicker, more durable plastic liner. In HydroHelp911 full encapsulation the liner is 14 to 20 mil thick and every seam is taped. Encapsulation also includes sealing the vents and installing a dehumidifier to control humidity in the whole space.

Is a Vapor Barrier Necessary in Your Crawl Space?

Vapor barriers are often necessary in crawl spaces, especially in regions with high humidity or where the crawl space is prone to moisture issues. A vapor barrier helps by blocking water vapor that rises from the ground, which can help prevent mold and mildew.

Signs That You Need a Vapor Barrier

Determining whether a vapor barrier is necessary depends on various factors. Here are some signs that you might need one:

High Humidity Levels: If you notice that the air in your crawl space is moist, it’s a sign that ground moisture might be migrating into the space.
Condensation: Visible condensation on your crawl space’s pipes, walls, or other surfaces indicates excessive moisture.
Mold and Mildew Growth: Visible mold and mildew growth in your crawl space indicate that moisture is present, and a vapor barrier can help mitigate this issue.
Wood Rot: Structural components showing signs of rot indicate that moisture control is needed.
Damp or Musty Odors: Persistent damp or musty odors originating from your crawl space can be another sign that moisture is infiltrating the area and that a vapor barrier is needed.
Water Damage: If you notice water stains or signs of water damage on the structural elements of your crawl space, a vapor barrier can help protect these components from further damage.
Cold Floors: Floors above the crawl space that stay cold can point to moisture affecting the insulation under the floor.
Peeling Paint or Rust: Moisture can cause paint to peel or metal elements to rust. If you notice these signs, it might be time to install a vapor barrier.

What Can Happen When Crawl Space Moisture Is Not Addressed?

Moisture that stays in a crawl space can lead to:

Structural Damage: Excess moisture can cause wood rot and weaken the framing of your home.
Mold and Mildew: Persistent moisture gives mold and mildew a place to grow.
Pest Infestation: Moist environments attract pests like termites, rodents, and insects, which can bring about additional damage.
Increased Energy Bills: Excess moisture can reduce the effectiveness of your insulation, causing your heating and cooling systems to work harder and increase your energy costs.
Indoor Air Quality: Air from the crawl space can move up into the house, so a humid crawl space can affect the air you breathe indoors.
Musty Odors: Constant moisture can produce musty smells that permeate your living spaces.

How Is a Crawl Space Vapor Barrier Installed?

Here is how HydroHelp911 installs a moisture barrier:

Inspection and Preparation

We thoroughly inspect the crawl space for any moisture issues, mold, or structural damage. We remove debris, old insulation, and sharp objects from the crawl space, ensuring the area is clean and dry before starting. We address current water issues, such as leaks or standing water, using a sump pump if necessary.

Measure and Cut the Vapor Barrier

We measure the dimensions of the crawl space to determine the amount of vapor barrier material we will need. Then, we cut the vapor barrier sheets to the appropriate sizes, allowing for overlaps at the seams.

Install the Vapor Barrier on the Ground

Then, we lay the vapor barrier sheets on the ground, ensuring they cover the entire floor area. The edges of the sheets are overlapped to provide comprehensive coverage. The sheets run across the ground only, and the overlapped seams are not taped.

Final Sealing and Inspection

We double check that the sheets overlap at every seam and cover the whole floor. We perform a final assessment to ensure the entire crawl space is covered and the vapor barrier is securely in place.

What Other Crawl Space Moisture Control Options Are There?

Crawl Space Encapsulation: Crawl space encapsulation involves sealing the whole crawl space with a heavy polyethylene liner that covers the floor, foundation walls, and piers, with every seam taped.
Dehumidifier Installation: Installing a dehumidifier made for crawl spaces can help maintain low humidity levels, reducing the risk of mold and mildew. This helps keep the air dry and prevents dampness that can lead to structural and health issues.
Sump Pump Installation: A sump pump removes accumulated water from the crawl space and is particularly useful in areas prone to flooding or with high water tables. By preventing standing water, a sump pump reduces the chances of damage from moisture and can be connected to a drainage system for efficient water removal.
Waterproofing: Waterproofing the crawl space is another effective method. This involves sealing off exterior vents, installing a moisture barrier on the walls and floor, and setting up a sump pump or drainage system to remove any water that can seep in.
Interior Drainage System: An interior crawl space drainage system (an interior French drain) is a perforated pipe set along the inside perimeter of the crawl space. It collects water and carries it to a sump pump, which sends it out of the house.

Which Crawl Space Moisture Solution Fits Your Home?

If you are seeing any of the problems above, a crawl space inspection can show the cause. HydroHelp911 has served homeowners across North and South Carolina since 2017, and our inspectors explain whether a vapor barrier, full encapsulation or drainage fits your crawl space.

Fixing Foundation Cracks From the Outside

Cory Parks — Wed, 04 Sep 2024 09:00:58 GMT

Have you noticed cracks in your home’s foundation? If so, you may be wondering how to fix them.

A foundation crack can be sealed from the outside of the wall or repaired from inside the basement or crawl space. This article explains, as general information, how an exterior crack repair works. HydroHelp911 repairs foundation cracks from the inside, and the sections below cover those methods too.

What Are Foundation Cracks?

Foundation cracks are openings or fissures in the foundation of a building or home. They can result from various factors and vary significantly in size, shape, and severity. The foundation is a critical part of the structure, providing stability and support. Although minor cracks are usually harmless and part of the natural aging process of a structure, more significant or developing cracks can indicate underlying issues. They may compromise the foundation and the overall structural integrity of the building.

What Causes Foundation Cracks?

Many factors can cause foundation cracks. Some of the most common include:

Soil Movement

Expansive soils are soils that significantly change in volume with water content fluctuations. The primary soil responsible for this behavior is clay soil. It expands when the soil absorbs water (e.g., rainfall, irrigation, or leaks). The expansion exerts upward pressure on the foundation, leading to heaving, an upward movement of the structure. During dry periods, the previously expanded soil loses moisture and contracts. This shrinkage can cause the foundation to settle or sink. This behavior can make the foundation move unevenly, causing cracks and other structural issues.

Soil settlement refers to the downward movement of the ground and foundation due to the consolidation and compaction of soil under load over time.

Even Settlement: When the entire structure settles evenly, minor issues may arise but are generally less severe.
Uneven Settlement: This occurs when different parts of the foundation settle at different rates or extents, leading to tilting, cracking, and other structural problems.

Water Problems

Water problems are a significant contributor to foundation issues. Poor drainage and water leakage around the foundation can lead to water accumulation, which in turn affects the stability of the soil and the integrity of the foundation itself. When water doesn’t drain away from the foundation adequately, it can pool around the structure’s base.

This pooling can cause the soil to become saturated, especially in soils that absorb and hold water (e.g., clay). Saturated soil expands and exerts pressure on the foundation walls and footings. This pressure can make your foundation walls bow, crack, and even move.

Leaks from pipes can lead to water infiltration, and poor ventilation can cause condensation to seep into the foundation material.

Temperature Changes

In regions with freezing temperatures, water can infiltrate small cracks in foundation materials. When surrounding temperatures drop, this water freezes and expands, causing the cracks to expand and potentially leading to significant foundation damage over time.

Design Flaws

Flaws in design or architectural plans, such as improper load distribution or unsupported overhangs, can result in uneven stress on the foundation, causing cracks and other issues.

Footings that are too shallow or improperly constructed may not provide adequate support. This can lead to the foundation settling or shifting, resulting in cracks and structural instability.

Using a concrete mix with improper proportions of cement, aggregate, and water can also compromise the strength and durability of the foundation, making it more susceptible to cracks and other damage.

Tree Roots

Large trees too close to a foundation can have extensive root systems that grow under and around the foundation. These roots can cause the soil to shift, leading to foundation displacement and cracks.

Heavy Rain and Flooding

Excessive water from heavy rain or flooding can saturate the soil around the foundation, which can lead to erosion, soil movement and a weaker foundation.

How Does HydroHelp911 Fix Foundation Cracks From the Inside?

Many foundation cracks can be repaired from inside the home. Our interior crack repair starts with a free inspection to find what caused the crack, because the repair works best when the cause is addressed along with the crack. Depending on the crack and the wall, the repair may include:

Crack injection: Epoxy or polyurethane crack injection fills the crack from the inside face of the wall to seal it against water.
Carbon fiber reinforcement: Carbon fiber straps are bonded across a crack to help hold the wall in place.
Wall stabilization: When a crack comes from a wall bowing inward, anchors set in firm soil or steel wall braces can stabilize the wall against further movement.
Interior drainage: When water comes in through a crack, an interior drainage system and sump can carry that water out from inside the basement or crawl space.

Our inspectors explain which method fits your home. Our repairs carry warranties with conditions, explained on our warranty page.

Some homeowners consider repairing a foundation crack themselves. A professional inspection can tell you whether a crack needs repair at all and what caused it, so the repair addresses the source.

How Does Fixing Foundation Cracks From the Outside Work?

An exterior crack repair works on the outside face of the foundation wall. As general information, it usually means digging the soil away from the wall to expose the full length of the crack, cleaning the crack, sealing the outside face of the wall and putting the soil back. Because the wall has to be exposed below grade, it is a bigger job around the outside of the house.

Do All Foundation Cracks Need a Repair?

Not all foundation cracks require repair, but assessing them carefully is essential. Here are some general guidelines:

Hairline Cracks: These are often a normal part of the foundation settling process. An inspection shows whether a crack needs repair, and a crack that changes over time is worth showing to an inspector.
Vertical Cracks: Vertical cracks are usually less concerning and can result from normal settling. A professional should evaluate them to determine if repair is necessary.
Horizontal and Diagonal Cracks: These can be more serious and might indicate pressure on the foundation walls or shifting of the soil. Such cracks usually require professional evaluation and repair.
Cracks with Water Seepage: Any crack allowing water to enter your basement or crawl space should be addressed to prevent mold, mildew, and further structural damage.

A foundation specialist can inspect any crack to find the cause and the right repair.

When Should You Call a Foundation Professional?

These are signs a foundation inspector should take a look:

If you notice cracks that are wide, long, or growing over time
If you see horizontal or diagonal cracks
If you observe water entering through foundation cracks
Any noticeable shifting, settling, or movement of the foundation
Walls that seem to be bowing or bulging inward
Problems in opening or closing doors and windows or noticing gaps around them
Floors that slope or feel uneven

If you notice any of these signs, schedule a free inspection with HydroHelp911. Our trained inspectors (not salespeople) look at your foundation and give you a written estimate for any repairs it needs. We serve homeowners across our service area in North and South Carolina.

Crawl Space Wall Insulation: Do You Need It?

Cory Parks — Fri, 16 Aug 2024 09:00:12 GMT

Crawl space wall insulation is often worth it in an unvented or encapsulated crawl space, where it helps keep the floors above warmer and the space drier. It is not always necessary: a crawl space that floods, or a dry, well vented one in a mild climate, may not need it.

This guide covers the materials and methods, the benefits, and when wall insulation may not be the right choice for your home.

Understanding Crawl Spaces & Their Types

Crawl spaces are narrow, unfinished stretches beneath homes, typically about 1 to 3 feet high. They commonly provide access to plumbing, electrical wiring, and other utilities. Crawl spaces can be either vented or unvented, each with distinct characteristics and requirements.

Vented vs. Unvented Crawl Spaces

Vented crawl spaces have openings to the outside air, intended to help with moisture control. However, they often bring in humid air, pests, and even cold air, leading to energy inefficiency and potential mold issues.

Unvented crawl spaces are sealed off from the outside air. They generally perform better in terms of energy efficiency when properly insulated and sealed.

What Are the Benefits of Insulating Crawl Space Walls?

Insulating crawl space walls can improve the comfort of your home. Here are some of the benefits:

Energy Efficiency and Cost Savings
Moisture Control and Mold Prevention
Improved Indoor Air Quality
Protection for the Wood Framing

Insulation Materials and Methods

Selecting the right insulation material for your crawl space helps you maximize moisture and temperature control. Here are some standard options:

Foam Board: These rigid panels are easy to install and offer excellent moisture resistance and thermal performance. Foam board insulation is particularly suitable for unvented crawl spaces.
Fiberglass: A preferred solution for vented crawl spaces, fiberglass is affordable and easy to install. However, it commonly requires a vapor barrier to prevent moisture issues.

Foam Board vs. Fiberglass

For homeowners on a budget, fiberglass insulation is typically the lowest cost option. It is widely available and relatively easy to install. However, while more affordable upfront, fiberglass may require more maintenance over time compared to foam board.

Best Insulation for Vented Crawl Spaces

An effective method for insulating vented crawl spaces is to install fiberglass batts between the floor joists, combined with a vapor barrier laid on the ground to manage moisture.

You could also use rigid foam board insulation between the floor joists and then seal the vent openings. Foam board or vent covers will reduce airflow while maintaining some ventilation for moisture control.

Best Insulation for Unvented Crawl Spaces

For unvented crawl spaces, rigid foam board attached to the walls is a common approach. HydroHelp911 does not install or recommend spray foam in crawl spaces.

Seal all seams between the boards with tape. This should create a continuous thermal barrier and enhance moisture control.

Is It Worth Insulating Crawl Space Walls?

The decision to insulate crawl space walls depends on several factors, including its condition, the climate, and your home’s overall energy efficiency needs.

One of the primary advantages of crawl space wall insulation is the potential for energy savings. By preventing heat transfer between the crawl space and the living areas above, insulated walls help maintain a consistent indoor temperature, reducing the burden on heating and cooling systems. While insulation typically brings to mind heat loss during winter, it’s equally beneficial in hotter regions, where it prevents heat gain.

A well insulated crawl space can also help protect ductwork and plumbing in the crawl space from condensation and freezing.

Insulating crawl space walls can also help with moisture. Crawl spaces are often damp, which can lead to mold, wood rot and pests. Rigid foam board on the walls resists moisture and helps keep the space dry.

Will Insulating a Crawl Space Make a House Warmer?

Yes, insulating a crawl space can make your house warmer during the winter by reducing heat loss through the floor. Insulation creates a barrier that keeps warm air inside your home.

Should You Insulate Floor Joists in a Crawl Space

Insulating the floor joists can be beneficial in vented crawl spaces. This approach will create a barrier that reduces heat transfer between the crawl space and the living area above, helping you maintain consistent indoor temperatures. In other words, no cold floors, better comfort during colder months, and consequently, lower energy consumption.

Should You Insulate Dirt Crawl Space Walls?

Insulation for dirt crawl space walls must prioritize stability, in addition to dampness control. Dirt walls are naturally uneven and porous, hence more susceptible to moisture infiltration and pest intrusion. Additionally, the lack of a solid surface requires careful preparation to ensure the material adheres properly and provides effective thermal and moisture barriers.

Rigid foam board insulation is often the best choice for dirt walls due to its resilience and ease of installation. Seams between the boards are sealed with tape to create a continuous layer. Fiberglass batts can be added between the floor joists for improved thermal performance if necessary, followed by proper sealing and regular maintenance.

Should You Insulate Wooden Crawl Space Walls?

Insulating wooden walls in a crawl space needs careful attention to moisture control, to protect the wood and keep the insulation working. Additionally, the choice of material and method must account for the potential for the wood to expand and contract with changes in temperature and humidity.

The best method for wooden crawl space wall insulation involves a combination of rigid foam board and a vapor barrier. The foam board insulates, and the barrier resists moisture. Seal the seams and edges with tape for a tight fit.

Should You Insulate Concrete Crawl Space Walls?

Insulating a crawl space with concrete walls involves specific considerations that differ from those with wooden or dirt surfaces. Concrete walls, while durable, are excellent conductors of heat, meaning they can allow its significant transfer between the crawl space and the exterior environment. This can lead to cold floors in winter and higher energy costs due to increased demand for heating systems. Furthermore, concrete is susceptible to water absorption, which can result in damp conditions indoors.

For those reasons, the insulation of concrete crawl space walls must address thermal and moisture control.

Rigid foam board insulation is popular due to its impermeability to water (a vapor barrier is still recommended to prevent moisture from penetrating the insulation). In some cases, an additional insulation layer, such as fiberglass batts, can be added between the floor joists for enhanced thermal protection.

When Is Insulating Crawl Space Walls Not the Right Choice?

There are situations where insulating a crawl space may not be necessary or even advisable:

Severe Flood Risk: If your crawl space is prone to flooding, insulation could trap moisture and lead to mold and rot.
Dry Crawl Spaces That Drain Well: In areas with slight moisture risk, the insulation cost may not justify the benefits.
Properly Vented Crawl Spaces in Mild Climates: In such cases, the energy savings from insulation may be minimal.

How to Tell If Your Crawl Space Needs an Insulation Upgrade

Observe your energy bills; if you notice a significant increase, it could be due to inefficient insulation.
Cold floors and drafts are other signs that your crawl space insulation may be inadequate.
Inspect the crawl space for visible damage or wear in the existing insulation, such as sagging floors, moisture damage, or pest infestations.
Mold growth and musty odors also suggest that the insulation is not effectively managing moisture levels.

A professional inspection shows whether the insulation needs an upgrade or a simple repair, and which areas need work.

Should You Insulate a Crawl Space Yourself or Hire a Professional?

Doing the insulation yourself can save on labor, but it takes time, effort and knowledge to do correctly. Mistakes in insulation or moisture control can lead to problems that cost more to fix later.

A professional can choose suitable materials, install them, and address moisture or other problems in the crawl space at the same time. HydroHelp911 installs crawl space insulation and can handle the moisture control around it, such as crawl space waterproofing, in the same project.

Why Does My Floor Feel Uneven When I Walk on It?

Cory Parks — Fri, 02 Aug 2024 09:00:38 GMT

If your floor feels uneven when walking, the two most common causes are a foundation that has settled unevenly and a subfloor that has weakened, often from moisture in the crawl space. Both can be repaired once an inspection shows which one you have.

This guide covers the main reasons a floor feels uneven, how to tell sloping from sagging, and how each problem is usually fixed.

Why Does My Floor Feel Uneven When I Walk on It?

If walking through your home makes you feel unsteady, or your step feels bouncy, you may be dealing with uneven floors.

The two main causes of uneven floors are uneven settlement and subfloor problems.

Common Cause 1: Differential Settlement

It is common for a home's foundation to settle gradually into the soil.

When one part of the foundation settles more than the rest, it is called differential settlement, and it can lead to sloping floors.

If your floor feels uneven when walking, this may be the reason. Differential settlement can happen for several reasons:

Soil that shrinks and swells: In the Carolina Piedmont, clay rich soils absorb water in wet seasons and shrink in dry periods, and that cycle can move a foundation unevenly. Soil that erodes can also leave gaps under part of the foundation.
Tree roots: Large trees near the house can dry out the soil under a foundation, which can lead to uneven settlement.
Nearby construction: Work close to the house can disturb the soil under the foundation.
Saturated soil: Heavy rain that soaks the ground around a foundation can soften soil that was supporting it.

How Can You Tell If Differential Settlement Is Causing Uneven Floors?

If the foundation is settling unevenly, you may notice sloping floors along with some of these signs. An inspector can tell you what they mean for your home.

Cracks: Cracks in ceilings, in walls or where drywall seams meet, often around corners, windows and doors or on the outside of the house.
Foundation damage you can see: cracks in the walls of the foundation, bowing or bulging, or water coming through.
Sticking windows or doors: Windows and doors that become hard to open and close can point to uneven settling that is shifting the frame of the house.
Gaps around the deck and other exterior features: New gaps around a deck, stairs, porch or chimney can mean the foundation is moving unevenly.
A musty odor: An unpleasant smell can point to a moisture problem in the crawl space, which can lead to mold.

Common Cause 2: Subfloor Issues

Homes built over a crawl space rely on a floor system of supports, joists and beams.

When that system is damaged, the floor can feel uneven when walking or start to sag. Common causes include:

Moisture problems: Water from any source can cause the wood to decay or bend, which weakens its support.
Installation problems: Mistakes during construction, or materials that do not hold up to moisture, can wear out early.
Wood eating insects: Wood boring beetles, carpenter ants and termites eat away at the wood and can weaken the floor framing.
Age: Years of daily use and exposure can gradually wear down the floor framing.

What Is the Difference Between a Sloping and Sagging Floor?

Knowing whether your floors are sagging or sloping helps point to the cause.

A sloping floor runs downhill at a fairly even angle, often across several connected rooms. That pattern usually points to the foundation.

A sagging floor dips in spots and can feel spongy underfoot. That pattern usually points to the joists, beams or supports under that part of the floor.

How Can You Spot a Sloping Floor?

A simple test is to set a small ball on the area you think is sloping. If the ball rolls away on its own, the floor slopes.

Another sign is a gap between the wall or baseboards and the floor that grows over time.

How Can I Fix Uneven Floors?

The first step is to find out why the floor feels uneven when walking. A self leveling compound can hide the dip without fixing what caused it, so start with an inspection that finds the cause.

There are three common types of repair:

Crawl space support: Repairing or replacing damaged floor supports, and where it helps, setting adjustable steel crawl space jacks under low areas.
Basement wall reinforcement: Stabilizing cracked or bowed basement walls with carbon fiber straps or wall anchors.
Foundation stabilization: When the cause is uneven settlement, the usual repair is underpinning with helical piers, push piers or slab piers that reach more stable soil.

Once piers carry the load, they can often be used to lift the foundation back toward its original position. How much lift is practical depends on the house and the soil, and the inspector sets expectations before the work starts.

How Can You Help Prevent Uneven Floors?

A few homeowner habits help keep water and roots from working against the foundation. These are tasks a homeowner or another trade looks after.

Homeowner tip, gutters: Clean the gutters regularly so they do not overflow and soak the soil next to the house.
Homeowner tip, trees: Plant new trees well away from the house so their roots stay clear of the foundation.
Interior drainage: In a crawl space or basement that takes on water, an crawl space drainage with a sump can carry groundwater out before it collects under the house.

If your floor feels uneven when walking, a foundation inspection can show the cause.

What Is the Cost of Underpinning With Helical Piers?

Cory Parks — Mon, 22 Jul 2024 09:00:30 GMT

The cost of underpinning with helical piers depends mainly on how many piers your home needs, how deep they have to go to reach stable soil, the soil itself and how easy it is to reach the foundation. A free inspection sets the number of piers, and the written estimate states the price.

Helical piers are often used in foundation repair because they help stabilize a structure with less disruption than some other underpinning methods. This article covers what drives their cost and how they compare with other foundation supports.

What Are Helical Piers and How Do They Work?

Helical piers, also called helical piles, are long steel shafts with plates shaped like a screw near the end. They are turned into the ground until they reach soil that is solid enough to hold the weight above. A bracket is then attached to the top of the pier to support the structure, and in many cases to lift it back toward its original position.

Helical piers do not need a large workspace, and because they screw into the ground, they can often be installed fairly quickly compared with some other methods. That makes them a common choice for fixing foundation problems.

The piers are made of steel, and their helix plates bear on the soil around them, which helps them hold their position.

What Is Underpinning?

Underpinning makes the foundation of a structure more stable. Sometimes the ground under a house starts to sink, or it was not strong enough from the start.

Underpinning addresses this by carrying the weight of the house down to firmer soil, or by spreading that weight over a larger area.

What Is the Cost of Underpinning With Helical Piers?

The cost of underpinning with helical piers depends on several factors, covered below. The price for your home is set in a written estimate after a free inspection. For a ballpark figure first, try our foundation cost calculator.

What Affects the Cost of Helical Piers?

Materials

Materials are one part of the cost. The pier length and the number of helix plates both affect the price, and extra pier length adds to it.

Number of Piers Needed

The number of piers has a direct effect on the cost. It depends on the weight of the structure and the soil, and more piers mean more material and labor.

Labor

Labor is a large share of the cost. It covers the crew, the equipment and any permits the project needs.

Type of Soil

Soil affects how complex the job is. Dense, rocky soil can be harder to get through, and soft or sandy soils can mean deeper installations to reach stable soil. In the Carolina Piedmont, piers often pass through clay that shrinks and swells, and on the coast, through sandy soil with a high water table.

Extent of Damage

The amount of damage to the foundation affects the size of the project. More damage can mean more piers, temporary supports or structural repairs.

Access and Landscaping

Piers are installed beside the foundation, so the area around the house affects the work. Tight access, or plantings and hardscape close to the walls, can add to the job.

How Do Helical Piers Compare With Other Foundation Supports?

Helical Piers vs. Concrete Piers

Concrete piers can provide solid support, but they take digging and curing time for the concrete. Helical piers can be installed faster with less disruption to the yard. They work in a range of soil conditions and can carry load right after installation, with no curing time.

Helical Piers vs. Push Piers

When steel piers are compared with helical piers, the comparison is usually with push piers. Push piers are also steel, but they are driven straight down with hydraulic equipment, using the weight of the house, until they reach a stable soil layer or rock. They have no helix plates.

Helical Piers vs. Straight Shaft End Bearing Piers

Straight shaft piers depend on end bearing, meaning they must reach a stronger layer of soil or rock that can carry the load. Helical piers can be adjusted in length and helix size to suit the soil, and they carry load as soon as they are installed, which suits sites where soil conditions are harder to predict.

Are Helical Piles Cheaper Than Concrete Piers?

The cost of helical piers and concrete piers depends on the home, the soil and the number of piers. Each fits different conditions, and an inspection shows which one suits the home. The written estimate states the price.

Common Questions About Helical Pier Cost

How Much Does Underpinning With Helical Piers Cost?

The price depends on how many piers the home needs, how deep they go, the soil and access around the house. Your free inspection gives you a written estimate for your home.

How Many Helical Piers Does a House Need?

It depends on the weight of the structure, the soil and the area that has settled. The inspector lays out the number of piers and where they go in your written estimate.

Do Helical Piers Come With a Warranty?

Yes. Our pier warranty covers no additional settlement in the area where the piers are installed, with the conditions listed on our warranties page.

How Do You Permanently Fix Squeaky Floors?

Cory Parks — Fri, 12 Jul 2024 09:00:10 GMT

Most squeaky floors come from small gaps where the subfloor, the joists or the floorboards can move and rub. The lasting fix closes that gap at its cause, usually from below the floor, and a floor that squeaks because it sags may need its framing repaired.

Many homeowners deal with squeaky floors, and there are several ways to fix them.

This article covers the most common causes of squeaky floors and how to fix them.

What Causes Squeaky Floors?

Before fixing the problem, you have to identify the root cause first.

There are many reasons why your floor may be squeaking. Here are some of the most common ones:

Changing Seasons

According to the Britannica Encyclopedia, wood contracts and expands as the temperature changes. Not just wood experiences this, but also other materials like metal and plastic. When the temperature rises, these materials expand. When it cools down, they contract.

Additionally, the wood absorbs moisture from the air and expands with high humidity. Leaks in a drainage system can also introduce excess moisture into your flooring. On the other hand, loss of moisture can lead to shrinkage.

While the expansion and contraction are often negligible on a small scale, they will be more noticeable in big structures such as floors. The squeaking sound is one sign of this.

Floor Joist Issues

A creaky floor often indicates an issue with the joist. Floor joists are wooden horizontal structures that provide support for the subfloor. They bear the load of the floor’s weight.

The squeaking usually comes from the gap between the joist and the subfloor. Over time, as buildings settle, the nails securing the joists’ subfloor can loosen. It allows movement that leads to squeaking sounds when pressure is applied to the floor above.

Other reasons include warped joists, lack of bridging, poor workmanship and poor quality materials.

Subfloor Problems

If it’s not the joists, then it may be the subfloor. Remember that a squeaky floor is often the result of a gap somewhere in the structure.

Squeaky subfloors often stem from the following reasons:

Uneven Subfloor: An uneven, out of level or sagging subfloor can create gaps in your flooring structure, which may need to be filled or supported below.
Poor Quality Materials: Subfloor materials that are of low quality or have degraded over time due to moisture exposure, insect damage, or natural wear and tear may not provide a solid, stable base for flooring.
Improper Installation: Improperly installed subfloors can lead to issues down the line, including squeaks. This can include insufficient nailing, incorrect spacing of the panels, or failure to leave enough space between panels to accommodate natural expansion and contraction.

Loose Tongue and Groove

A loose tongue and groove on floorboards can move when not firmly attached. Over time, the tongue and groove, the interlocking parts of the wood planks, can dry out and shrink, leaving gaps for movement. With foot traffic or weight bearing on the floor, the planks can then rub against each other, producing a sound.

Delamination

Delamination of wood flooring means the layers of the wood are coming apart. This can happen in engineered wood or materials like plywood.

The separated layers may move when pressure is applied, such as when someone walks over them. The movement between these layers can result in a squeaking noise. Typically, delamination occurs due to moisture damage, adhesive failure, or subpar manufacturing processes.

How Do You Permanently Fix Squeaky Floors?

Once you know where the squeak comes from, you can fix it. A quick fix can quiet a squeak for a while, but the noise may come back if the cause is still there. The repairs below address the cause.

Working From Below

If you have a crawl space or access to the underside of your floors, here are some solutions that you can try:

Construction Adhesive

If gaps in your flooring are causing the squeaky noise, applying a construction adhesive can be an effective solution. You can carefully inject the adhesive into these gaps using a caulking gun, securing loose areas. This can reduce the squeaking, and often stop it.

Screwing or Installing Shims

If the gaps are too wide and the adhesive doesn’t work, you can try screwing or installing shims. Screwing helps secure the joists to the subfloor, while shims can fill in any gaps.

The screws must be countersunk so as not to protrude above the floor surface. Also, check areas where the nails from the subfloor missed hitting the joists. In these spots, drive screws to fasten the subfloor to the joists securely.

You can also insert thin pieces of wood or shims into the gap. It’s crucial not to force the shim too tightly, as this could cause further lifting of the subfloor. Instead, apply construction adhesive and gently tap it in just enough to stop the squeak.

Stabilize Warped and Twisted Joists

If your joists are warped or twisted, you can stabilize them by attaching planks along the joist. Fasten the plank to the joist and the subfloor above to anchor them together effectively. Additionally, you can place blocks of wood between two joists. These blocks will straighten the joists, helping stabilize your joists and the above subfloor, thereby limiting movement.

If gaps remain due to the warping, you can add shims to prevent the creaking noise.

Working From Above

If you can’t access the area under your floors, the only option is to fix it from above.

Try the following methods:

Moisture and Temperature Control

If humidity and temperature swings are behind the squeak, controlling moisture under the floor can help.

HydroHelp911 can help with the moisture under your floor:

Dehumidifier: A crawl space dehumidifier removes moisture from the air under the floor.
Vapor barrier or crawl space encapsulation: A sealed liner helps keep ground moisture out of the crawl space.
Insulation: Crawl space insulation reduces heat flow through the floor.

Homeowner tip: heating and cooling equipment, thermostats and home automation systems also affect indoor temperature and humidity. Those are handled by an HVAC contractor or the homeowner.

Lubrication and Adhesives

You can apply lubrication or adhesive to secure the boards with loose tongues and grooves. This method may also work for other exposed parts of flooring that are loose.

Powdered graphite or talcum works as an excellent lubricant. For adhesives, wood glue, epoxy, or construction adhesive are good options.

Repair or Replacement

For damaged parts of your flooring, such as delaminated or cracked boards, it is better to replace than repair them. If the damage is minor, you can fill the gaps using a wood filler or putty and then sand it down. However, we recommend replacing the entire board if the damage is extensive.

When Should You Call a Professional?

You can do some of these fixes yourself, but some floor problems need a professional.

A floor that squeaks and also feels uneven or sags can point to a problem in the framing or the foundation. When joists or beams under the floor have weakened, structural repair in the crawl space or sagging floor repair supports the floor from below. HydroHelp911 inspects crawl spaces, framing and foundations across North and South Carolina and can show you what is behind the squeak.

What Is the Purpose of Crawl Space Insulation?

Cory Parks — Wed, 03 Jul 2024 09:00:49 GMT

The purpose of crawl space insulation is to slow heat moving between the crawl space and the rooms above, which keeps floors warmer in winter, helps the house hold a steady temperature and can lower energy bills. Paired with moisture control, it also helps protect the crawl space from condensation.

This article explains how crawl space insulation works, its benefits and the materials used.

What Is a Crawl Space?

A crawl space is an unoccupied and often unfinished area between the ground and the home's first floor. If you have a raised foundation, your house likely has one.

The crawl space often holds important parts of the home, such as plumbing, ductwork and electrical lines, so its condition matters.

What Is the Purpose of Crawl Space Insulation?

Crawl space insulation refers to the insulation material installed on the walls, floors, or ceilings of a crawl space. It helps keep a home's temperature stable and comfortable by slowing heat and cold moving through the floor. Combined with moisture control, it can help limit the condensation that leads to mold and rot.

What Are the Benefits of Insulating Your Crawl Space?

Cold floors, high energy bills or a damp smell can be signs that your crawl space needs insulation. For many homes, the benefits are worth the cost.

Here are some reasons to insulate your crawl space:

Lower Energy Bills

Sealing air leaks and adding insulation can lower heating and cooling costs, and the savings depend on the home.

The crawl space is located right below the ground floor. If it’s not insulated, the cold from the ground can make the floors chilly. This makes the heater work extra hard to keep the house warm, which costs more money.

In many homes, the heating and cooling ducts also run through the crawl space, so a cold or poorly insulated crawl space can make the system work harder.

Prevention of Moisture and Mold

Most molds are found outdoors; they live in the soil, plants, and decaying matter. They can enter your house through flooding, leaks, damp areas, and condensation.

Mold needs three things to grow: humidity, warm temperature, and a food source. If you have moisture problems, you can limit mold by depriving it of one of these things.

According to the National Insulation Association, insulation plays a part in preventing moisture problems. In a crawl space, insulation works best together with a vapor barrier or encapsulation that keeps ground moisture out.

Improved Air Quality

Reducing mold and excess moisture helps improve a home's air quality, and sealing gaps during insulation work can limit outside air coming up from the crawl space.

Comfort

Insulation helps keep floors warmer in winter and rooms more even in temperature from season to season.

Common Types of Insulation Materials Used in Crawl Spaces

Not all insulating materials work the same, and not all materials suit the conditions of a crawl space.

These are the common ones.

Fiberglass Insulation

Fiberglass is a long used insulation material. It is affordable and fairly easy to install between floor joists. In a damp crawl space it can absorb moisture and sag, so it works best when the crawl space is kept dry, for example after encapsulation.

Foam Board Insulation

Foam board is a rigid panel, often faced with foil, that resists moisture and air. It gives a clean look on crawl space walls. It does not fill gaps on its own, so seams are taped, and it can take more work to fit in a crawl space with many obstacles.

Spray Foam Insulation

Spray foam is sprayed on and expands to fill gaps, cracks, and crevices. HydroHelp911 does not install or recommend spray foam in crawl spaces. Spray foam can trap moisture and can hide termite activity and wood rot from inspection. In HydroHelp911's experience, the pest control companies it has spoken with will not warranty a crawl space against termites when spray foam is on the walls or floor.

Factors to Consider Before Insulating Your Crawl Space

The material that insulates best on paper is not necessarily the best choice for a crawl space. There are other factors to consider before installing insulation in a crawl space. Here are some of them:

Type of Crawl Space

Vented Crawl Spaces: Vented crawl spaces have openings to the outside. The idea is that the natural airflow dispels moisture. In reality, open vents allow warm, humid air to flow in and condense on cooler surfaces. With full encapsulation and a dehumidifier, the vents stay closed all the time. Without encapsulation, the long standing guidance is to leave the vents open in the warm months and closed in the cold months so pipes do not freeze. If you have a vented crawl space, the insulation is typically installed under the subfloor between the floor joists.
Sealed or Encapsulated Crawl Spaces: In sealed or encapsulated crawl spaces, the insulation is typically applied to the crawl space walls and subfloor. Encapsulation with a dehumidifier air seals the crawl space and helps right away, even when the old insulation is not replaced, although building code still requires insulation.

Insulation Material

Different insulation materials resist heat flow differently. The right choice depends on factors such as the local climate, the type of HVAC system used, and the part of the building being insulated (for example, roof, walls, or floors).

Accessibility and Safety

Not all crawl spaces are the same. Some crawl spaces have inaccessible areas that might render some material less effective.

For instance, if the crawl space is too small for a person to fit in, it might be challenging to install foam board insulation. Fiberglass may be a better choice in this case.

Cost, Durability, and ROI

The cost depends on the material and the size of the crawl space. A lower cost material is not always the better value if it does not hold up in crawl space conditions. The crawl space insulation installation page shows the range HydroHelp911 publishes for that work, and your free inspection gives you a written estimate.

How to Insulate a Crawl Space: DIY vs. Hiring a Pro

Once you take into account these factors, you can begin to insulate the crawl space. In general, here are the steps you’ll take:

Dress in old clothing that you don’t mind getting dirty, bring a flashlight and thoroughly inspect the space.
Remove any clutter, outdated insulation materials, and debris.
Identify and seal any leaks, cracks, or openings, including vents, and do necessary repairs.
Thoroughly dry the entire area.
Lay down a vapor barrier.
Install the insulation material. Each material requires a different installation method. Follow the manufacturer’s instructions.

A professional can help choose materials that suit your crawl space and handle the moisture control around the insulation.

Signs Your Crawl Space Needs Insulation

How do you know if your crawl space needs insulation? Ask yourself the following questions:

Are your utility bills higher than expected?
Do areas in your home have varying temperatures?
Is the floor above your crawl space unusually cold or hot for the season?
Do you notice drafty areas in your home?
Have you experienced allergic reactions or respiratory issues recently?
Do you notice bad smells in your house that you can’t pinpoint?

If you answered yes to most of these questions, your crawl space might need insulation, and an inspection can confirm it.

What’s the Ideal Basement Humidity Level?

Cory Parks — Wed, 26 Jun 2024 09:00:39 GMT

The ideal basement humidity level is between 30% and 50%, the range the EPA recommends for homes. In summer, a dehumidifier usually does most of the work of keeping a basement in that range; in winter, the air is drier and a humidifier may be needed instead.

Whether a basement is storage or living space, its humidity affects the rest of the home. This guide covers why basements get humid, what humidity can lead to and how basement humidity control works through the year.

Why Are Basements Humid?

Due to their location below ground level, basements are naturally prone to humidity. The most common reason is that the surrounding soil retains moisture. It seeps through the foundation walls and floors, increasing the humidity levels inside. Poor ventilation, inadequate insulation, and leaks in the foundation can exacerbate the problem, creating a damp and musty environment.

Soil Moisture

Moisture in the soil around your home can penetrate basement walls, especially if the foundation is not sealed correctly. The ground becomes saturated during heavy rains or snowmelt, leading to higher humidity levels inside the basement.

Poor Ventilation

Basements often lack proper ventilation, which prevents damp air from escaping. Without sufficient airflow, humidity accumulates, creating an ideal environment for mold and mildew growth.

Foundation Leaks

Cracks or gaps in the foundation allow water to enter the basement. Even small leaks can significantly raise the humidity levels and provoke persistent dampness.

What Problems Can a Humid Basement Cause?

A humid basement can affect the air in your home and the structure of the house.

How Can Humidity Affect Health?

High humidity gives mold and mildew a place to grow, and the EPA notes that mold can affect people with allergies or asthma.

Structural Damage

Excess moisture can wear down wood framing, flooring and other parts of the house over time.

Unpleasant Environment

A humid basement often feels uncomfortable and smells musty, which can make the space less usable for storage or living.

Low Humidity Issues

Low humidity is less common, but very dry air can dry out wood and damage some stored items.

What Is the Ideal Basement Humidity Level?

We recommend keeping basement humidity between 30% and 50%.

This range is recommended by sources including the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC).

Keeping basement humidity in this range helps prevent the problems that come with air that is too damp or too dry.

What Makes 30% to 50% the Ideal Humidity Level?

This range is neither too dry nor too damp. It helps with:

Mold and mildew: The EPA advises keeping indoor humidity below 60%, ideally between 30% and 50%. Staying in that range helps keep mold and mildew from growing.
Wood and metal: Humidity in the recommended range helps limit wood rot, warping and corrosion.
Comfort: Air that is neither damp nor very dry is more comfortable.
Stored items: Books, electronics and clothing stored in a basement hold up better.

In short, keeping a basement between 30% and 50% humidity helps limit mold, protects the structure and keeps the space comfortable. The seasons change what it takes to stay in that range.

The Right Basement Humidity Levels During Summer

Summer brings warmer temperatures and higher humidity, especially in the humid Carolina summers, so the ideal basement humidity in summer takes more work to hold. Check the levels often.

How Do You Manage Basement Humidity in Summer?

A dehumidifier removes excess moisture from the air. Fans can help move air through the space, and sealing leaks or cracks in the foundation helps keep moisture out.

The Right Basement Humidity Levels During Winter

In winter, humidity levels tend to drop, which can cause different kinds of issues in your basement. If possible, you should try to keep it somewhere between 30 to 50 percent.

How Do You Maintain Basement Humidity in Winter?

If the air gets too dry in winter, a humidifier can add moisture. Insulated basement walls help keep surfaces warmer, and checking the levels regularly shows whether you are in the ideal range.

What Affects Basement Humidity Levels?

Several factors influence the humidity levels in your basement, including:

External environment & climate conditions
The state of your foundation
The effectiveness of your home’s ventilation system

External Environment

Climate and weather patterns affect basement humidity. The levels are naturally higher in regions with high rainfall or air humidity.

Foundation Condition

A well maintained foundation without open cracks lets less moisture into the basement. Regular checks help catch problems early.

Ventilation

Fans, vents and dehumidifiers help regulate indoor humidity and keep excess moisture from building up.

Why Track Your Basement Humidity Levels?

Checking basement humidity regularly helps you find problems early:

Early detection: A spike or drop shows up before it causes damage.
Comfort: You can keep the basement comfortable through the seasons.
Avoiding high humidity: You can act before mold or moisture damage starts.
Stored items: You can protect what you keep in the basement.

How Does Basement Humidity Control Work?

How Do You Lower Basement Humidity?

These are the main ways to reduce basement humidity:

Use a Hygrometer: A hygrometer in the basement shows the humidity so you can keep it in the recommended range.
Dehumidifiers: Where humidity often runs above 50%, a dehumidifier removes moisture from the air and helps limit mold.
Humidifiers: They can add necessary moisture to the air during cold months, preventing it from dropping below 30%.
Ventilation: Your basement needs adequate airflow. Install exhaust fans, vents, or windows to allow damp air to escape and fresh air to circulate.
Seal Cracks and Leaks: Sealing cracks and leaks helps keep moisture out.
Insulation: Insulating basement walls helps limit condensation.
Interior Drainage: An interior drainage system helps handle groundwater that seeps in.

How Does an Interior Drainage System Work?

An interior drainage system (an interior French drain) is a perforated pipe set along the inside of the foundation, under the basement floor. It collects groundwater and carries it to a sump pump, which sends it out of the house.

How Does Basement Insulation Help?

Insulation reduces condensation, which forms when warm, humid air meets cool basement walls or floors. By keeping surfaces at a steadier temperature, insulation helps with lowering the humidity levels in the basement.

How Do You Keep Your Basement at the Ideal Humidity?

Knowing what causes basement humidity, controlling it and checking the levels regularly helps keep a basement comfortable and dry. For moisture that keeps coming back, HydroHelp911's interior basement waterproofing can address the water at its source.

Sump Pump Alternatives You Should Be Familiar With

Cory Parks — Fri, 17 May 2024 09:00:28 GMT

Installing a sump pump is one of the best ways to remove unwanted water from around your foundation. However, this is not the only way to achieve that goal. There are several sump pump alternatives that every homeowner should know about.

Sump pump alternatives can help with water in a basement or crawl space. Some are simple maintenance a homeowner can do. Others, such as an interior drainage system, are installed by a professional. Here is how each one works.

What Is a Sump Pump and How Does It Work?

A sump pump is part of a system that collects water in your basement or crawl space and pumps it up and out of your home. A sump pump helps you avoid the problems that standing water and excessive moisture cause by ejecting it away from your foundation.

Sump pumps consist of a few main components, including the following:

Sump pit: This reservoir in your basement or crawl space floor houses the pump and stores water.
Sump pump: The pump activates when the water in the pit reaches a certain level, pushing the water up the discharge pipe.
Discharge pipe: The discharge pipe connects to the pump and leads to outside the home. It is responsible for conveying the water to a place where it cannot cause damage to your foundation.
Check valve: The check valve is a component of the discharge pipe. This valve allows water to move up the pipe but prevents it from falling back into the pump.
Power supply: Most sump pumps connect to an electrical outlet that provides the power the pump requires.
Battery backup: Sump pumps that include a battery backup will remain functional even when the main power supply is unavailable.
Float switch: A sump pump float switch is a device that detects rising water levels in a sump pit and triggers the sump pump to turn on and remove the excess water.
Sump pit cover: While not essential, a sump pit cover conceals stagnant water in the pit and reduces unwanted odors.

What Are the Alternatives to a Sump Pump?

Sump pumps work well, but they are not the only way to deal with water around a foundation. These sump pump alternatives can help keep moisture out of your basement or crawl space.

Homeowner Tip: Regular Gutter Cleaning

Gutters play a big part in keeping rainwater out of a basement or crawl space. They collect water from the roof and carry it to a downspout. When gutters clog, they can overflow and drop water on the ground next to the foundation, where it can pool and seep in. Keeping the gutters clean helps them work as intended. Gutter cleaning is homeowner maintenance or work for a gutter company.

Homeowner Tip: Downspouts That Empty Away From the House

Water moves from the gutter into a downspout, which should carry it away from the house. A downspout that is too short can leave water near the foundation, where it is more likely to seep into a basement or crawl space. A downspout that empties well away from the walls helps. This is also homeowner maintenance or work for a gutter company.

Interior Drainage System

An interior drainage system is the alternative that HydroHelp911 installs. A crawl space drainage system (sometimes called an interior French drain) is a perforated pipe set in a channel of gravel along the inside of the foundation. Water that reaches the channel moves through the pipe to a sump pit, and the sump pump sends it out of the house.

Interior drainage runs along the inside of the foundation, under the crawl space or basement floor. It is one of the most common ways to help keep water from building up under the home.

What Are the Signs Your Foundation Has a Water Problem?

It helps to know when better drainage may be needed. These signs can mean your foundation is struggling with water or humid air:

Musty odors: Excess moisture can cause unpleasant smells, which are often the first sign of a basement or crawl space moisture problem.
Mold and mildew: As moisture rises, mold and mildew can grow.
Standing water: Pools of water in a crawl space or basement are a clear sign the drainage needs attention.
Water damage: Drainage problems can lead to staining, wood rot and damaged stored items.

How to Support Floor Joists in a Crawl Space

Cory Parks — Fri, 26 Apr 2024 09:00:43 GMT

Floor joists in a crawl space are usually supported in one of three ways: adding joists or beams, installing blocking between the joists, or adding support columns under the framing. Which one fits depends on why the joists need support, and an inspection shows that.

These are the three options for how to support floor joists in a crawl space:

Addition of More Floor Joists
Installing blocking
Support Columns for Your Crawl Space

In the following sections, we’ll explain these three options more thoroughly. After that, we’ll explain why floor joists fail and share a few signs you should look out for that indicate this is the case.

Addition of More Floor Joists

A problem with crawl space floor joists can go back to how they were installed. If the house was built with too few joists, or with joists spaced too far apart, the floor above can sag or bounce.

In these cases, the repair is often to add joists, beams or both, or to sister new lumber alongside the existing joists. Added framing helps the floor carry its load and can help keep the floor above level.

Installing Blocking

Blocking is another way to stiffen crawl space joists. It does not look like much, but it helps spread the weight of the floor, and everything on it, to the joists next to each other.

Blocking is a piece of wood fastened between floor joists. It ties the joists it touches together so they share the load.

Support Columns for Your Crawl Space

In most crawl spaces, the joists rest on beams, and the beams rest on piers or columns that carry the weight down to footings in the soil. When a pier or column settles or deteriorates, the beam and the floor above it can sag.

Adding support under the beams, such as adjustable steel crawl space jacks on solid footings, gives the framing new points of support. This is part of our structural repair under the floor.

What Causes a Crawl Space to Fail?

These are common reasons crawl space framing fails:

Rotting joists: Most crawl space joists are wood, and wood can rot when it stays damp. Rotted joists can sag or bounce.
Missing framing: Too few floor joists, beams or support columns can leave the floor without enough support. This usually goes back to how the house was built.
Foundation settlement: A small amount of even settlement is normal. Uneven settlement can cause problems in the crawl space and in the rest of the home.

What Are the Signs You Need Crawl Space Joist Support?

If you notice any of these signs, an inspection can show what the framing needs:

Deformed floorboards: Any deformation in your floorboards can reveal there is an issue with the joists below it.
Sloping floors: Damage to your crawl space floor joists can cause your floors to slope in a specific direction rather than being flat.
Wall cracks: Rot and pest problems can cause problems with your floor joists since these features often consist of wood. It can also result in cracks that form in the walls at any level of your home.
Sticking windows and doors: Problems with crawl space joists can make doors and windows hard to open and close.

How Can You Help Prevent Crawl Space Damage?

These steps help prevent crawl space damage:

Control crawl space moisture: Excessive moisture is one of the leading causes of crawl space damage. It can rot wood framing and lead to mold and mildew. Encapsulation helps keep ground moisture out, and a dehumidifier in an encapsulated crawl space, along with interior drainage where water collects, helps keep humidity down.
Address uneven settlement: When a crawl space foundation has settled unevenly, piers are a common repair. Steel piers reach firmer soil and connect to the foundation to help stabilize it, and in many cases to lift it back toward level.
Have your crawl space inspected: If you are unsure whether your crawl space needs more support, an inspection shows what is going on and what would help.

Have Your Crawl Space Inspected by a Pro

Repairing crawl space joists is usually a job for a professional, who can find the cause and recommend the repair that fits.

How Serious Is a Crack in the Foundation of a House?

Cory Parks — Mon, 22 Apr 2024 09:00:30 GMT

How serious a crack in the foundation of a house is depends on its cause. Cracks from concrete shrinking as it cured, or from a small amount of even settlement after construction, are usually not a structural concern. Cracks from water pressure or uneven settlement can point to structural issues that need repair. This article covers the common causes of foundation cracks, how to tell them apart and how they are repaired.

Are All Foundation Cracks a Cause for Concern?

It is natural to worry about a crack in your house's foundation, but not all cracks are a structural concern. Some foundation cracks are just unsightly and don’t affect the structural integrity of your home’s foundation. For example, it is typical for poured concrete foundations to exhibit cracks due to shrinkage during the concrete curing process. While these cracks could allow water to enter your basement or crawl space and for that reason should be sealed, they aren’t structural.

Foundation cracks can also result from a normal process known as foundation settlement. A small amount of uniform settlement after construction is pretty common and may cause a few cracks. An inspection shows whether a crack comes from normal settlement.

A free inspection shows what a foundation crack means. Small hairline cracks that do not get longer or wider and do not let water in are often cosmetic, and an inspection confirms whether that is the case. The next section covers signs that call for a closer look.

What Are the Signs a Foundation Crack Needs a Closer Look?

If you notice any of these, it is worth having the crack inspected:

A crack that is getting wider: A widening crack often points to ongoing movement.
A crack that is getting longer: Like widening, a crack that keeps growing longer often comes from a structural problem.
Water coming in: A crack that lets water seep through needs attention. Look for dampness, mold and mildew, water stains or the water itself.
Crack direction: Horizontal, diagonal and stair step cracks often point to a foundation problem. A single vertical hairline crack in a poured concrete wall is usually minor, while several vertical cracks close together can be a sign of something more.

Common Causes of Foundation Cracks and Repair Solutions

Most structural cracks in a house's foundation come from hydrostatic pressure or differential settlement.

Hydrostatic Pressure

Hydrostatic pressure is the force water puts on the surfaces it touches.

When water does not drain away from a foundation, it collects in the soil next to the walls and presses against them. Over time, that pressure can crack the wall, make it bow or cause other foundation problems.

When water pressure is the cause, the repair usually relieves the pressure with interior drainage and stabilizes the wall if it has moved.

Differential Settlement

A small amount of uniform settlement is normal after construction. Differential settlement is different: it happens when parts of the foundation shift unevenly, and that uneven movement often cracks the foundation.

Differential settlement is usually repaired with piers. The two main types are push and helical piers, and both help stabilize the foundation against further settlement in the area where they are installed.

The piers are installed down to firmer soil and then attached to the foundation with brackets. Through that connection, the crew can often lift the foundation back toward level without causing damage.

What Should You Do About a Crack in Your Foundation?

How to Get Rid of Moisture Under a House

Cory Parks — Wed, 17 Apr 2024 09:00:10 GMT

Moisture under a house usually comes from one of three places: a drainage system that has failed, roof and yard water collecting next to the foundation, or damage to the foundation itself. Once the source is found, the fix is usually interior drainage, foundation repair, encapsulation, a dehumidifier or a combination of them.

Crawl spaces and basements are prone to high humidity, and that moisture can affect the rest of your home. This article covers the causes and the fixes.

What Causes Moisture Under a Home?

There are several reasons the area under your home can become too damp. These are three of the most common.

Poor Drainage

Standing water or high humidity under your home can come from a lack of proper drainage. Many homes have interior drainage systems, floor drains and sump pumps. When one of these clogs, breaks or leaks, water can collect in the basement or crawl space.

Gutter, Downspout and Grading Issues

Roof and yard water is another common source. Clogged gutters can spill water right next to the foundation, and downspouts that empty close to the house can cause puddles near the walls. A yard that is flat or slopes toward the house can also send water toward the foundation.

Direct Foundation Damage

Damage to the foundation itself can let moisture into the area below your house. Cracks or walls that have moved can let water in, and they can also point to settlement or water pressure against the walls. In those cases, an inspection shows what the foundation repair needs to address.

How Do You Get Rid of Moisture Under a House?

The right fix depends on where the water comes from. These are the most common ones.

Repair or Add Interior Drainage

If the moisture comes from a drainage system that has failed, the usual fix is to repair it or add an interior system. That starts with an inspection of the drainage you have. The fix may be an interior drainage for crawl spaces, an interior French drain or a sump pump that carries the water out.

Homeowner Tip: Keep Gutters and Downspouts Clear

Gutters, downspouts and the slope of the yard are maintenance a homeowner or another trade looks after. Cleaning the gutters helps them carry roof water away from the foundation, and downspouts that empty well away from the house keep that water from pooling near the walls.

Fix Issues With Your Foundation

When foundation damage lets moisture in, it often comes from one of two sources: uneven settlement or water pressure against the walls.

A small amount of even settlement is normal. Uneven settlement is when one part of the house moves more than another. It is often addressed with steel foundation piers, which reach firmer soil below the foundation and connect to it with brackets to help stabilize the settled area.

Water pressure is the other source. When the soil around a foundation is saturated, the water pressing against the walls can lead to bowing, cracks and leaks. The repair usually combines interior drainage to relieve that pressure with crack repair where the wall has cracked, and a bowing wall may also need stabilization.

Crawl Space Encapsulation

Encapsulation is another way to manage moisture. Crawl space encapsulation covers the crawl space floor, foundation walls and piers with a liner, with every seam taped, so ground moisture stays behind the barrier. Closing the crawl space off this way also helps keep humid outside air out.

Dehumidification

A dehumidifier is another way to help keep the area under your home dry. After the sources of moisture are addressed, you can install a dehumidification system to help keep the basement or crawl space dry.

A dehumidifier lets you monitor and manage the relative humidity under your home. It is often added after encapsulation.

What Causes Floors to Squeak When You Walk on Them?

Cory Parks — Mon, 15 Apr 2024 09:00:23 GMT

Floors usually squeak when you walk on them for one of three reasons: they were installed poorly, the wood moves with seasonal swings in temperature and humidity, or the foundation has settled unevenly. The right repair depends on which one it is, so this article covers each cause and its fix.

What Are the Common Causes of a Squeaking Floor?

There are many possible causes of a squeaking floor. These are the three main ones.

Poor Installation

Installation problems are a common reason a floor squeaks. If the house was built with too few floor joists, or joists spaced too far apart, the floor can start squeaking early on. The wrong kind of subfloor, the wrong nails or other installation mistakes can cause squeaks too.

Changes in Temperature and Moisture

Changes in temperature and humidity are another cause. As the temperature or humidity rises and falls, wood floors expand and contract, and that movement can make them squeak. Larger swings can also contribute to cracks in floors, walls or ceilings.

Differential Settlement

If you have been a homeowner for any length of time, there is a chance that you have heard of foundation settlement. There are two types of foundation settlement, uniform and differential. Here’s what you need to know:

Uniform foundation settlement is fairly typical and usually not a cause for concern, such as a small amount of even settlement after construction.

Differential settlement happens when a foundation settles into the ground unevenly. It can cause problems throughout the home, and squeaking floors on any level are one of them.

What Is the Best Way to Repair a Squeaking Floor?

The repair depends on the cause. A professional looking at your floor problems will usually recommend one of these:

Repairing the Floor Framing or the Flooring

When a floor squeaks because of how it was installed, the fix is in the framing or the flooring itself. Loose subfloor can be fastened to the joists, and joists that are too few or too weak can be reinforced with sistered floor joists. A problem in the finished flooring, such as loose boards, is work for a flooring contractor.

Running a Dehumidifier

When temperature and humidity swings are behind the squeak, a dehumidifier in the crawl space under the floor can help.

A dehumidifier lets you monitor and manage the humidity under the floor and keep it steadier through the year, which can help in a humid climate like the Carolinas.

Stabilizing the Foundation

When uneven settlement is the cause, the repair is usually foundation piers.

Foundation piers come in more than one form, including push piers and helical piers, which serve a similar purpose. The piers are installed down to firmer soil and connected to the foundation with brackets.

Once the piers carry the load, they can often be used to lift the house back toward level without causing damage. Our pier warranty covers no additional settlement in the area where the piers are installed, with conditions on our warranties page.

Get Help With Your Squeaking Floors

Finding the source of a squeaking floor can be hard. A professional inspection can find whether the cause is in the floor framing, the moisture under the floor or the foundation.

How Do I Protect My Crawl Space From Termites?

Cory Parks — Mon, 08 Apr 2024 09:00:02 GMT

If you are a homeowner, there is a decent chance that you understand the damage termites can cause. The complications that result from these insects can be especially serious when they infiltrate your crawl space. This article covers steps that can help keep termites out of your crawl space and the signs to watch for.

Termite Prevention Methods for Crawl Spaces

Several steps can help make a crawl space less inviting to termites:

1. Crawl Space Encapsulation: Termites are drawn to moisture. Crawl space encapsulation covers the crawl space floor, walls and piers with a sealed liner, which helps keep ground moisture out and leaves pests fewer ways in.

2. Dehumidification: Perhaps the most direct way to reduce moisture in any space is to set up a dehumidification system. The right dehumidifier allows you to monitor and manage the relative humidity in your crawl space. Keeping relative humidity low makes the crawl space less inviting to termites.

3. Drainage System Repairs: If your drain pipes are damaged or faulty, they can cause water to pool. Pooling water invites termites and other pests to enter your home. Repairing the drainage system and checking it regularly helps keep water from collecting.

4. Homeowner Tip, Grading: Look at the ground around your crawl space. If it is flat or slopes toward your home, water can pool near the foundation. Grading is homeowner or landscaping work.

5. Homeowner Tip, Gutters and Downspouts: Clogged gutters can spill rainwater next to the foundation. Cleaning them regularly helps carry roof water away from the house.

6. Repair Cracks and Openings: Cracked foundation walls, gaps and openings in a crawl space can let pests in. Foundation crack repair and sealed openings help close those paths.

7. Eliminate Food Sources: Remove any food substances in and around your crawl space. Any food that’s left behind will attract insects, including harmful termites.

Signs of Termite Infestation in Your Crawl Space

Prevention lowers the odds of termites, but they can still arrive, so it helps to know the signs:

1. Dead Termites: Dead termites in your crawl space can be a sign that live termites are nearby.

2. Discarded Termite Wings: Some termites have transparent wings that they shed when they swarm to start new colonies. Discarded wings can mean a colony is nearby.

3. Termite Droppings: Also known as frass, termite droppings are small, oval pellets that can be light tan to dark brown. The sight of frass strongly indicates that termites have made a home in your crawl space.

4. Damaged Lumber: Termites feed on wood, so termites in a crawl space can damage the lumber. This damage has several forms, including cracking, blistering, and overall deterioration.

5. Chewing Noises: While it seems surprising, you can often hear the presence of termites in your walls and flooring. Listen for light chewing noises to tell if you have an infestation.

Adverse Effects of a Termite Infestation

It is crucial to understand the negative effects that a termite infestation can have. As you’ll soon see, noticing the signs of an infestation can help you prevent damage. Below is a quick list of the adverse outcomes termites can cause:

1. Lumber Damage: The best known effect of termites is wood damage. Termites feed on wood, which can weaken the crawl space framing, floors and walls.

2. Allergic Reactions: The presence of termites can result in significant reactions in those allergic to them. An allergic reaction may be the first indication you notice that termites are present.

3. Fungal Infections: Termites can also carry fungi that can spread throughout your home. These fungi can affect your wood and weaken it, while the termites use it as a food source.

What to Do If You Think You Have Termites

If you suspect you have a termite infestation in your home, the best approach you can take is to hire a pest control service in your area. Rather than taking a DIY approach to pest removal, hiring a professional allows you to diagnose your issue and resolve it.

Protect Your Crawl Space

After discovering a termite infestation, hiring a pest control company is an excellent choice. However, many of the termite prevention measures we mentioned require the assistance of a crawl space expert.

HydroHelp911 serves homeowners across North and South Carolina with crawl space repair and encapsulation, the moisture control side of termite prevention.

Crawl Space Moisture Control: How It Works

Cory Parks — Mon, 01 Apr 2024 09:00:36 GMT

Crawl space moisture control works by finding where the water and humid air come from, then blocking ground moisture with a vapor barrier or encapsulation, removing humidity with a dehumidifier and carrying standing water out with a sump pump. Keeping the crawl space dry helps protect the wood framing and the air in your home.

Why Does Crawl Space Moisture Matter?

Your crawl space may be out of sight, but it affects the rest of your home. This article covers where crawl space moisture comes from, what it can lead to and how it is controlled.

Understanding Crawl Space Moisture

Sources of Moisture

Various factors can cause crawl space moisture, including drainage issues, leaking pipes, and inadequate ventilation.

If there are drainage problems around your home, groundwater may seep into the crawl space, resulting in standing water and high humidity. The ground around your home can absorb water like a sponge, leading to dampness in the crawl space.

Leaking pipes can also contribute to moisture in the crawl space, especially if they go unnoticed for extended periods.

Air carries moisture, and when it cools down, it turns back into water. The everyday activities in your home, like cooking, showering, and even breathing, add moisture to the air, which can end up in your crawl space. Inadequate ventilation can trap moisture in the crawl space, making everything damp and humid.

What Can Happen When Crawl Space Moisture Is Not Addressed?

Damage to the Wood Framing: Wood absorbs water, and damp wood can develop wood rot, which weakens the framing over time. Metal in the crawl space can rust and corrode as well.
Mold and Mildew: Mold and mildew grow in damp places. They look and smell unpleasant, and mold can bother people with allergies or asthma.
Indoor Air Quality: Air from the crawl space moves up into the living spaces. If that air carries moisture and mold spores, it affects the air in your home.

How Is Crawl Space Moisture Controlled?

Vapor Barriers

Installing vapor barriers is a common way to keep ground moisture out of the crawl space air. They are large plastic sheets that cover the ground and block moisture rising from the soil.

Dehumidifiers

A dedicated dehumidifier under the house helps keep humidity in a healthy range. It draws in air, removes moisture and blows the drier air back out. Running a dehumidifier in the crawl space makes it a less inviting place for mold and mildew.

Sump Pumps

In areas prone to flooding or with a high water table, such as the Carolina coast, a sump pump removes water that collects in the crawl space. If standing water is a common problem, a sump pump in the crawl space, with a battery backup for power outages, carries that water out of the house.

What Are the Steps to Control Crawl Space Moisture?

Step 1: Assess the Situation

The first step is to assess the extent of moisture in your crawl space and identify the primary sources of water intrusion. Take a flashlight and examine the area under your house. How moist is your crawl space, and where could the water come from? What you find decides which methods fit.

Side note: If you would rather not go into your crawl space, our free inspection covers it. We also provide full crawl space encapsulation, which turns a damp crawl space into a cleaner, drier one. Our encapsulation warranty requires annual maintenance at the owner’s expense; the terms and their conditions are on our warranties page.

Step 2: Choosing the Right Solution

Based on what the assessment finds, choose the moisture control methods that fit. Depending on the condition of your crawl space, that may be a vapor barrier, a dehumidifier, a sump pump or a combination.

Step 3: Installation and Action

Whether it is a vapor barrier, a dehumidifier or a sump pump, the system works best when it is installed correctly.

Preventive Measures to Keep Moisture Under Control

Routine Inspections

Check your crawl space regularly for signs of moisture or damage, so small problems are found early. Keep an eye out for leaks, check your moisture barriers, and ensure that your dehumidifier and sump pump (if you have them) work correctly.

How Do You Maintain Crawl Space Moisture Control Systems?

Moisture control systems need regular care to keep working. Clean your dehumidifier’s filter, check the sump pump’s operation before the rainy season, and repair any tears or damage to your vapor barrier.

Why Is a Dry Crawl Space Important?

Controlling moisture in your crawl space helps protect the structure of your home and the air you breathe in it. Knowing where the moisture comes from and how it is controlled is the first step toward a dry crawl space.

When Should I Be Concerned About Cracked Tiles?

Cory Parks — Mon, 25 Mar 2024 09:00:01 GMT

A single cracked tile often comes from an impact, wear or an installation problem and can simply be replaced. Cracked tiles are worth a closer look when several crack in the same area, the floor under them feels uneven, or there is dampness or mold nearby, because those can point to the subfloor or the foundation.

This guide covers the signs to watch for and what to do about cracked tiles.

What Can Cracked Tiles Mean?

Cracked tiles can be cosmetic, or they can be a sign of a problem beneath the surface. An inspection can show what is causing them.

What Signs Should You Watch For?

These are the things to look at:

Multiple Cracks

It helps to check your house now and then for signs of cracks in walls and floors. A single crack may not mean much, but several cracks in the same area, or across the home, can point to a bigger cause.

Many cracks together can mean the foundation is shifting or the support under the floor is not enough. When that cause is not addressed, it can lead to further damage.

If you notice several cracked floor tiles, a professional can find the underlying cause and recommend the right repair.

Uneven Flooring

Cracked tiles are more than just an eyesore. They can also make your floor feel uneven and uncomfortable to walk on. To identify if your tiles are damaged, run your hand over the tiles and feel for any bumps or dips. Even slight changes in the tiles’ surface could indicate a deeper issue with the floor underneath or foundation.

Water Damage

Cracked tiles can let water through. Moisture that gets under the tile can damage the subfloor and rot the wood beneath it. Look for water stains, mold or dampness near cracked tiles, which are signs of moisture getting in. Repairing the cracked tiles helps limit water damage.

Grout Issues

When tiles crack, the grout between them is often damaged too. Watch for discolored or crumbling grout, which can let in water and affect how the floor looks.

What Should You Do About Cracked Tiles?

Here are the steps to consider:

Repairing the Tiles

A small crack can grow over time. There are two main ways to fix cracked tiles. Both are usually done by a tile installer or the homeowner.

The first option is to replace the entire tile, which involves removing the damaged tile and installing a new one. This method is best for larger cracks or when the tiles are extensively damaged.

The second option is to use specific products to seal the cracks. These products fill in the gaps and prevent further damage, a method best suited for more minor cracks.

In either case, choose a suitable replacement tile or sealant that matches the existing tiles in your home to maintain a consistent look.

Professional Inspection

If you notice large or several cracks in your tiles, a professional inspection can find the cause, especially if the floor also feels uneven.

Preventive Measures

Besides repairing cracked tiles, consider implementing preventive measures to protect your flooring from future damage. First, consider sealing the grout to protect it from water damage and other harmful elements. You can also add a protective coating to the surface of your flooring to further safeguard it from scratches or other types of damage. As a side note, it is crucial to be cautious when moving heavy furniture, as this can put undue stress on your floors and cause further cracking or damage. These steps help protect the look and condition of your floor.

When Should You Get Expert Advice?

Cracked tiles can seem minor, but they can point to a problem in the floor or foundation underneath. Every home is different, and an inspection is the way to know what is behind the cracks. HydroHelp911 serves homeowners across North and South Carolina.

Signs of Termites and Termite Damage in a Crawl Space

Cory Parks — Mon, 11 Mar 2024 09:00:11 GMT

Most homeowners know that termites can damage the wooden support structures in a crawl space. However, few know how to recognize the signs of termite infestation. In this article, we’ll review the signs your crawl space might have a termite problem and what to do about it.

Signs of Termites and Termite Damage in a Crawl Space

Damaged Wood

Mud tubes on a wood beam in a crawl space

The most obvious sign of termites in your crawl space is damaged wood. Since termites use wood as a food source, they will be happy to chew on timber structural supports.

When termites chew the wood in your crawl space, it will undergo multiple noticeable changes. For instance, the wood will likely have long cracks and gaps while also showing discoloration and a spongy texture.

Damaged wood matters because it can weaken the crawl space framing. As termite damage spreads, beams, joists and other wood supports can lose strength.

Termite Droppings

Termite droppings look like tiny pellets, each less than 1/16 of an inch in length, and have a light brown color similar to wood. Termites often drop their feces in prominent piles near the wood they consume.

Termite Wings

There are various types of termites in a termite colony. Some have wings larger than their bodies. When these winged termites find a mate, their wings fall off. Therefore, if you notice transparent, oval wings about one inch long in your crawl space, that’s a strong sign termites are present. Shed wings can mean a colony is nearby, even if you do not see the termites themselves.

Dead Termites

The presence of dead termites is one of the surest signs you’re dealing with an infestation. After all, if you see dead termite bodies, the odds are there are living ones nearby. Identifying a dead termite can be tricky, though. As noted above, there are multiple types of termites, each with a different appearance.

Worker termites are often the smallest at about ⅛ of an inch long. They have a light tan color, small pinchers, and a thorax that appears entirely fused to their abdomen.

Soldier termites are similar in size to worker termites. However, soldiers tend to have a darker color, especially on their heads, and they have much larger pinchers.

Lastly, there are winged termites mentioned previously. These termites have bodies similar to worker termites, but the main difference is they have wings about one inch long.

Mud Tubes

Termites depend on moisture to survive; if their conditions become too dry, they will quickly perish. To avoid that, termites form moist mud tubes to travel safely. Mud tubes consist of termite saliva, dirt, and other materials. The tubes typically form on the exterior surface of your foundation, and they can be several inches long and wide. The presence of these tubes indicates termites have entered your crawl space. If you notice them, calling pest control services is your best next step.

Cracked or Bubbling Paint

Cracks and bubbles in paint can also indicate the presence of termites. Since termites must avoid drying out to survive, they tend to generate a lot of moisture. As this moisture accumulates below a layer of paint, it is common for the paint to form bubbles and cracks in some cases.

Bubbling paint is not always a sign of termite damage. Therefore, if you are unsure what caused your paint cracks and bubbles, check your crawl space for pests.

Foul Odors

Termites themselves do not have a distinct smell. However, termite activities can cause the places they infest to have an unpleasant odor. As noted above, termites need moisture to survive. Moisture encourages the growth of mold and mildew, as well as wood rot, creating a musty smell which flows up into your home’s living area. A musty smell in your home often points to excessive moisture.

What to Do If You Find Signs of Termites

If you find signs of termites in your home’s crawl space, the best approach is to hire a pest control company to identify and remove the termites from your home.

Professional pest control teams are prepared to diagnose and treat pest problems in your home’s crawl space. Contacting one of these teams when you see one or more of the signs described above is a way to limit the damage termites cause.

If the termites have already caused a considerable amount of damage, you’ll need repairs as well. Therefore, having a foundation repair team you can trust is essential.

Get Help From a Professional

As noted above, seeking the help of a professional pest control team is the first step to take when dealing with termites in your crawl space. However, once the pest control team finishes their work, you may also require attention from a foundation specialist.

If you are a homeowner who has experienced crawl space damage, whether from termites or not, HydroHelp911 is here to help across North and South Carolina. We provide structural repairs for crawl spaces.

What to Do When Your Basement Floods

Cory Parks — Mon, 04 Mar 2024 09:00:56 GMT

When your basement floods, the steps are to remove the standing water, dry the space, repair what the water damaged, and then find and fix the cause so it is less likely to happen again. Interior drainage and a sump pump are the usual long term fix for groundwater.

The sections below walk through each step.

Remove Standing Water

You’ll probably find standing water on your basement floor if your basement has flooded. Unsurprisingly, one of the first steps when responding to a flooded basement is removing the standing water.

The removal of standing water can occur in several ways. However, using a wet vacuum or some form of pump is the most efficient way to achieve this goal. It can also help to run a dehumidifier to dry out your basement more quickly.

Repair Damage the Flooding Caused

If your basement has flooded, there is a good chance of some form of water damage. Water can harm both the structural elements that comprise your basement and any items you store in it.

Start by assessing the state of any belongings, furniture, or other items that were in your basement when the flooding occurred. You’ll likely find that many of these items require significant repairs or replacements depending on the severity of the flood.

During this stage, you should also take a close look at the structural components of your basement. It is essential to address any wooden structures, as they are most susceptible to rot when excessive moisture or standing water is present.

Rotted joists, beams or other framing that the flood damaged should be repaired or replaced so the structure stays sound.

Resolve the Cause of the Flooding

After evaluating the state of your basement’s structures and any water damage to your stored belongings, it’s time to address the root cause of your basement flood. Below is a list of common factors that lead to basement flooding and a quick explanation of how to resolve them:

Grading (homeowner tip): When the ground around the house is flat or slopes toward the foundation, water drains toward the basement, where it is more likely to seep in. Grading is homeowner or landscaping work.
Gutters (homeowner tip): Clogged gutters can overflow and leave water next to the foundation, where it can seep into the basement. Cleaning the gutters regularly helps.
Hydrostatic pressure: Water in the soil around the foundation can build pressure against the basement wall and push water through small cracks. An interior drainage system relieves that pressure by carrying the water to a sump pump.
Drainage system failure: Sometimes, you may have a drainage system intended to prevent basement flooding. Unfortunately, flooding can still occur when this system becomes clogged, backed up, or damaged in some way. The best remedy in this case is to repair or replace the elements of your drainage system that have become faulty.
Leaks in your plumbing system: Leaks in your plumbing system are also a common cause of basement floods. Hiring an experienced plumber allows you to diagnose the cause of your flooding and find the most appropriate solution.
Foundation cracks: Regardless of the cause, if your basement foundation walls have cracks, there is a chance that water and moist air can get in. Sealing the cracks and addressing their cause helps keep water from leaking in.

How Can You Help Prevent Future Basement Floods?

The last step is to make future floods less likely. Improving the basement's drainage is one of the main ways.

An interior basement drainage system collects water that reaches the basement and carries it out. It can include an interior French drain along the walls, floor drains and a sump pump. An inspection shows which parts your basement needs.

Along with drainage, consider interior basement waterproofing, which manages the water that reaches the walls and floor and carries it out of the house, which helps keep water from collecting in the basement.

A flooded basement can be overwhelming, and a professional can help you find the cause. HydroHelp911 serves homeowners across North and South Carolina with interior basement waterproofing services and foundation repair.

Sagging Floors: Why They Happen and How to Fix Them

Cory Parks — Fri, 23 Feb 2024 09:00:59 GMT

Sagging floors usually happen for one of three reasons: the floor was built with too few joists or joists spaced too far apart, the foundation has settled unevenly, or moisture in the crawl space has weakened the wood. Each cause has its own repair, from added framing and crawl space supports to foundation piers.

If your floor has a dip or feels uneven underfoot, this article covers why sagging floors happen and how they are fixed.

What Are the Main Causes of Sagging Floors?

There are several reasons a floor may begin to sag, and each one calls for its own repair.

Construction Errors

The first cause is how the floor was built.

In a home with a crawl space foundation, the floors rest on wood joists and beams. The joists run parallel to one another and sit on beams that run the other way. If the house was built with too few joists, or with joists spaced too far apart, the joists can sag under the weight of the floor over time.

Differential Foundation Settlement

Another cause of sagging floors is differential foundation settlement. Your foundation depends on the soil below it for support. If that soil shifts or sinks, your foundation and the rest of your home will move.

A small amount of even settlement is typical after construction. Differential settlement is uneven, and it can damage the structure.

When it happens, signs can show up throughout the home, such as foundation cracks, sticking windows and uneven or sagging floors.

Structural Decline and Moisture

Even a well built floor can weaken over time as the joists and beams decay. As the support weakens, the floor can begin to slope or sag.

Floor supports can receive damage from general wear and tear and direct impacts. However, moisture can also be a significant factor in the longevity of structural components primarily consisting of timber.

Excess moisture is common in basements and crawl spaces, and when it is not managed it can lead to wood rot. As rot spreads, the joists and beams weaken, which can lead to sagging and sloping floors.

For more information, see Sagging Floors Repairs and Causes.

How Do You Fix Sagging Floors?

Repairing a sagging floor is usually a job for a professional, because the repair has to match the cause. These are two common repairs.

Foundation Underpinning

If your sagging floor results from differential settlement, your repair team may suggest solving the issue via a service called underpinning. Underpinning involves inserting foundation piers into the earth and connecting them to your foundation to add support. Push and helical piers are the most widespread pier types for this job.

A foundation repair team installs push piers using a hydraulic pump to press them into the earth until they hit bedrock or firm strata. The top of the piers attaches to your foundation via a bracket. Once the connection is in place, the piers can often be used to lift the foundation back toward level without causing damage.

Helical piers are similar, with one main difference: rather than being pressed in, they are shaped like large screws and turned into the ground until they reach soil that can support the home.

Structural Reinforcement

Structural reinforcement is usually the repair when a floor sags because of the wood framing in the crawl space. It can take several forms, depending on what the framing needs.

For example, if the house was built with too few joists, the repair may add joists, sister new lumber to joists or add bridging between them. Adjustable crawl space jacks can also support a sagging beam from below. These add stiffness and support to the floor.

It also helps to address any moisture that caused the joists or beams to rot, with interior drainage or a crawl space dehumidifier. Reducing moisture makes it less likely the floor will sag again.

What Is House Leveling, and How Does It Work?

Cory Parks — Fri, 16 Feb 2024 09:00:57 GMT

House leveling is a foundation repair that lifts a house that has settled unevenly back toward level. It is usually done with steel push piers or helical piers that are installed down to firmer soil, connected to the foundation with brackets and then used to raise and support the settled sections.

This article covers why houses become unlevel, how house leveling works and the signs that a house may need it.

Why Do Houses Become Unlevel?

Before we discuss how house leveling works, let’s discuss why a house might become unlevel. The primary cause of an unlevel house is a phenomenon called foundation settlement.

Foundation settlement occurs when the soil below your home shifts or sinks. When this happens, your foundation and the rest of your home will move along with the soil. Following construction, a minor amount of uniform settlement is normal and does not typically cause structural damage.

The other type, differential settlement, involves uneven shifts in the foundation, and it can damage the structure.

When differential settlement happens, it can lead to a range of problems in the home. The next section covers the main ways a house is leveled and stabilized.

How Do You Fix an Unlevel House?

Leveling a House With Push Piers

Installing push piers is one way of leveling a house that has experienced differential settlement. To employ this method, a foundation repair team will use a hydraulic pump to push a set of piers deep into the earth until they reach a firm layer of soil or bedrock.

At the top, the piers attach to the foundation with a bracket, which connects the house to the firmer soil below. Once the connection is made, the crew can lift the house back toward level without causing damage.

Installing push piers can bring a house back toward level and help stabilize the foundation against further settlement in the area where they are installed. How much lift is practical depends on the house and the soil, and the inspector sets expectations first.

Leveling a House With Helical Piers

The second method of leveling a home we’ll describe is similar to the first. The only difference here is the type of piers involved in the house leveling.

Instead of push piers, the inspector may recommend screw shaped helical piers, which are turned into the ground until their plates bear on stable soil.

Like push piers, helical piers attach to the foundation with a bracket. Once the connection is made, the crew can lift the house back toward level and the piers help stabilize it against further settlement.

What Are the Signs of Differential Foundation Settlement?

These signs can mean a home has settled unevenly and may need leveling:

Stuck doors
Jammed windows
Foundation cracks
Bulging foundation walls

Why You Might Need a Sump Pump for Your Crawl Space

Cory Parks — Fri, 09 Feb 2024 09:00:09 GMT

You might need a sump pump for your crawl space if water collects there after rain, groundwater seeps in, or the house sits over a high water table, as many coastal Carolina homes do. A sump pump collects that water in a pit and pumps it out of the house, which helps prevent the mold, wood rot and pests that standing water invites.

This article explains how a crawl space sump pump works and what it helps with.

Moisture Problems in Crawl Spaces

Before we discuss sump pumps directly, let’s discuss some of the reasons why they are important. The main reason sump pumps become necessary for many homes is that crawl spaces and basements are prone to accumulating more moisture than other parts of your house.

Illustration of a sump pump inside a sump pit

Since crawl spaces are at the lowest point of a building, it is only natural that this is the area of your home where it is most common for standing water to appear. Whether due to stormwater runoff, groundwater, or some other source, puddling and flooding can become a prevalent problem for crawl spaces.

Additionally, many crawl spaces have excess moisture as well. This results from the fact that warm, humid air can flow into a crawl space and condense on cool surfaces.

Excess humidity and standing water are both worth removing. When moisture builds up, it can damage the wood framing and encourage mold and mildew, which can affect the air in your home.

How Does a Sump Pump Work?

Here is how a sump pump handles that water.

Most sump pumps include a few main elements. First, there is the sump pit, which is nothing more than a reservoir that collects water from your crawl space. Other drainage, such as an interior French drain or floor drains, can feed into the sump pit.

Once the water is in the pit, the pump moves it through a pipe up and out of the house, to a place where it is away from the foundation.

Benefits of a Sump Pump

These are the main benefits of a sump pump in a crawl space:

Water removal: The primary reason to use a sump pump for a crawl space is to remove water. Removing water leads to all of the following benefits on this list.
Less mold and mildew growth: Less water in the crawl space makes mold and mildew less likely, which helps the air in your home.
Insect and pest prevention: When you allow water to stand in your crawl space, it can become a breeding ground for insects that eat wood and other pests. Sump pumps give those pests fewer opportunities to reproduce and infest your home.
Fewer foul odors: Water in your crawl space can also produce foul odors that eventually seep into your home. A sump pump helps limit those odors.

Those are the main benefits of a crawl space sump pump installation. A pump is not the only way to handle crawl space water, though.

Other Ways to Manage Crawl Space Moisture

Sump pumps are one way to manage crawl space moisture. Pairing a sump pump with the methods below is often the most complete approach:

Interior drainage system: An interior crawl space drain (an interior French drain) collects groundwater along the inside of the foundation and carries it to the sump pump.
Crawl space encapsulation: Encapsulation covers the crawl space floor, walls and piers with a sealed liner, which helps keep ground moisture out.
Dehumidification: Following an encapsulation service, it is often a good idea to set up a dehumidification system. Many dehumidifiers will allow you to set an ideal relative humidity for your crawl space.

Again, these solutions typically work best when you use them together rather than choosing just one. Consulting with a trusted foundation professional is the best way to find out which of these services is best for your home.

Sloping Floors: Is Your Home at Risk or Just Aging Gracefully?

Cory Parks — Mon, 29 Jan 2024 23:33:25 GMT

A sloping floor is worth having checked when the slope is noticeable over a short distance, is getting worse, or comes with sticking doors and windows. Floors usually slope because the wood framing under them has weakened or the foundation has settled unevenly, and each cause has its own repair.

This article covers why floors slope, when a slope matters and how sloping floors are fixed.

Why Are Your Floors Sloping?

The first step toward knowing whether you should worry about sloping floors is to understand how floors become sloped in the first place. As mentioned in the introduction, there is more than one reason why this can occur. The sections below will explain the two most common ones.

Direct Floor Damage

One of the most common causes of a sloping floor is damage to the floor itself. Over time, floors and their supporting structures in your crawl space can take damage from several sources.

For instance, excessive moisture in your home can cause wood to rot. When the crawl space supports below your floor start to decay, it is typical for the floorboards they support to begin sagging. This sagging causes the entirety of your floor to become uneven.

Wooden floorboards can also become cracked, bent, and bowed through use and age. Regardless of what causes the damage to your floor and its joists, the result is often a noticeable floor pitch ranging from mild to severe.

Differential Foundation Settling

Sometimes, the source of your sloping floor has nothing to do with your actual floor. Instead, a sloping floor can be an indication of foundation settling.

When the soil below a foundation sinks or shifts, the foundation will sink and shift in turn. This often results in a change in the rest of your home.

Some foundation settling is normal, especially in the first years after construction. Differential settling is different: it is uneven, and it can give floors a noticeable pitch and make doors and windows stick.

How Much Slope Is Too Much?

When you notice that a floor in your home has begun to slope, it can be challenging to diagnose the cause on your own. However, some signs can indicate that you should worry about your sloping floor.

Mainly, paying attention to the degree of the floor slope is essential. To evaluate the slope, you’ll need to remember that the floor has a vertical rise and a horizontal run.

Generally, a floor with a noticeable rise or fall over a short run is worth having checked. This degree of slope can indicate a problem with your floor or your foundation.

With that said, it’s also important to consider comfort and safety. Any time a sloping floor is difficult to walk on or causes a tripping hazard, a professional repair team can help.

Are Sloping Floors More Common in Certain Homes?

Any home can develop a sloping floor. However, some houses are more likely to have uneven floors than others. For instance, sloping floors are far more common in older homes that have had more time to settle over the years. Older homes are also more likely to have deteriorating structural materials in their crawl space foundations that can lead to sloping floors.

As hinted in the sections above, sloping floors are also more common in homes that have experienced foundation problems, regardless of age. When a foundation becomes damaged or settles unevenly, it can cause many issues, including sloping floors, stuck doors, jammed windows, and much more.

Will a Sloping Floor Collapse?

Whether or not a sloping floor will collapse depends on several factors, such as the cause of the slope and the total degree of damage. For example, collapse is unlikely when a floor has a slight slope due to normal foundation settling.

A sloping floor can collapse only when the framing damage is well advanced or the problem has gone unaddressed through extreme neglect. HydroHelp911 has seen two or three cracked joists in a row with two to three inches of sag and slope that had still not collapsed. A sloping, sagging, or bouncy floor is still worth having evaluated, because the cause usually continues until it is addressed and the repair scope follows how many joists are affected.

What Are the Best Ways to Fix a Sloping Floor?

Finding the best way to fix your floor depends entirely on the cause. For example, if you find out that your floor slopes due to damage to the floor itself, the best solution is to repair the floor and its underlying structure.

At times, you may be able to replace sloping floorboards on your own. However, a professional repair team can help your repair project run smoothly, safely, and successfully.

Similarly, if your floor slopes because of a foundation problem, there is little to no opportunity for you to repair this issue on your own. Instead, you’ll need to find a foundation repair team to diagnose and solve the problem. Sometimes, underpinning with steel piers is the repair. It uses piers to stabilize the foundation and, in many cases, lift it back toward level.

Get Help for Your Sloping Floors

A sloping floor can have several causes, and an inspection shows which one applies. A floor that slopes significantly or becomes difficult to walk on may point to a problem with the structural support in your crawl space or the foundation. In either case, a professional inspection is a sensible first step toward leveling your floors.

What’s the Cost of a Sump Pump Battery Backup?

Cory Parks — Mon, 22 Jan 2024 09:00:52 GMT

The cost of a sump pump battery backup depends on the type of backup, its battery capacity, and the sump system it is part of. A free inspection gives you a written estimate for your basement. For many homes with a sump pump, a backup is worth it, because it keeps the pump running when the power goes out.

This post covers what drives the cost of a battery backup, what it does and when it matters most.

How Much Does a Sump Pump Battery Backup Cost?

The cost of a sump pump battery backup depends on:

The type of backup system and its features
The battery capacity, which affects how long it can run the pump
The interior drainage and sump system it is part of
The condition of the sump pit and the discharge line

HydroHelp911 gives you a written estimate after a free inspection, and our cost calculator gives a ballpark figure first. Our backup sump pump installation page covers the work in more detail.

Many homeowners wonder whether a battery backup is worth the cost, since the pump does not use it during normal operation. As the rest of this article shows, it does its work when the power fails.

What Does a Sump Pump Battery Backup Do?

Sump pumps collect groundwater from around the foundation in a basin called a sump pit, then pump it up a pipe and out of the house.

When the system runs as designed, it helps keep water out of the basement. But it can fail in several ways.

All sump pumps need power, and most run on the home's electricity. If the power goes out, the pump stops, which can lead to basement flooding.

That is where a battery backup helps. It keeps the pump running for a time during a power outage or a problem with the normal power supply, which lowers the risk of flooding and water damage.

Who Needs Sump Pumps the Most?

A sump pump can be a helpful part of any basement drainage system, and some homes need one more than others. For a basement that floods regularly, a sump pump is often part of the fix.

Homes near a large body of water, homes on the Carolina coast with a high water table, and homes at the bottom of a slope that sends stormwater toward the house often see more water in the basement.

A foundation with cracks can also let water in, and even uncracked concrete can let water through when water pressure builds up outside the wall.

Many basement drainage systems include both a sump pump and a battery backup to keep it running when the power goes out.

Why Is a Battery Backup Important for Your Sump Pump?

When a sump pump loses power, water keeps filling the sump pit until it overflows, and then it can spread across the basement floor.

That water can damage stored belongings, rugs and furniture. Basement flooding also encourages mold and mildew, and the EPA notes that mold can trigger asthma episodes in people with asthma.

A battery backup helps keep a drainage system that relies on a sump pump working through an outage.

What Else Helps Manage Basement Moisture?

Other services can help too. Interior basement waterproofing manages water that reaches the basement walls and floor and carries it out. A dehumidifier lets you set and hold the humidity in your basement.

A professional can help you understand which drainage options fit your basement.

Common Questions About Sump Pump Battery Backups

How Much Does a Sump Pump Battery Backup Cost?

It depends on the type of backup, its battery capacity, the sump system it is part of, and the work around the sump pit. Your free inspection gives you a written estimate, and our cost calculator gives a ballpark figure first.

Is a Sump Pump Battery Backup Worth It?

For many homes it is, because a sump pump stops when the power goes out, and storms often bring outages and heavy rain together. A battery backup keeps the pump running for a time during an outage.

What Warranty Comes With a Sump Pump?

Our sump pumps carry a 3 year warranty on parts only, which can be extended to a lifetime parts and labor warranty through our annual maintenance program. The full terms are on our warranties page.

Why It’s Important to Keep Your Basement Dry

Cory Parks — Mon, 15 Jan 2024 09:00:51 GMT

It is important to keep your basement dry because moisture can damage stored belongings, flooring and furniture, rot wood, rust metal and let mold grow. The main ways to keep it dry are repairing cracks, interior waterproofing and drainage, and a dehumidifier.

Because basements sit below ground, their humidity can be hard to control. This article covers why controlling moisture matters and the signs that a basement is too damp.

What Can Moisture Do to Your Basement?

When basement moisture is not controlled, it can lead to the problems below.

Damage to Stored Belongings

Although a basement is the perfect place to store some of your belongings, doing so comes with a risk. Standing water, condensation, and high levels of humidity can all cause water damage to any sensitive items you store downstairs. When the moisture is not addressed, the damage can spread.

Growth of Mold and Mildew

As the moisture and humidity levels in your basement grow, so does the risk of mold and mildew. Mold and mildew can also affect indoor air quality, especially for people with asthma. Eventually, spreading mold can even begin to affect the structural integrity of the wood that makes up your flooring structure.

Rot and Rust

Metal and wood in a basement do not hold up well when moisture stays high. Moisture leads to rot and rust, which wear these materials down.

Ruined Flooring and Furniture

Unsurprisingly, a lack of dryness in your basement can also cause damage to any flooring, carpeting, or furniture in your basement. This is especially true when you have standing water in your basement, which typically causes hardwood flooring to buckle and rot while also saturating carpets, making them a breeding ground for foul scents and bacteria.

What Are the Signs of Too Much Moisture in Your Basement?

If you notice any of these signs, a free inspection can show what is causing the moisture.

Condensation: Condensation on walls, ceilings and other surfaces usually means the humidity is too high.
Humidity: A hygrometer is one of the most precise ways to check whether your basement is dry enough. The EPA recommends keeping indoor humidity between 30% and 50%.
Standing water: Standing water in a basement points to a water problem worth having inspected.
Mold and mildew: As moisture builds, mold and mildew can spread more readily. Mold and mildew can also affect indoor air quality.
Unpleasant scents: Another key indicator of excessive moisture is foul odors that arise from your basement. Unpleasant smells can result from mildew, rot, and other water problems.
Having to empty your dehumidifier constantly: A dehumidifier that fills up again and again is a telltale sign that there is more moisture in the air than there should be.

Because basements are underground, they are prone to high humidity, especially in summer. If you notice any of these signs, addressing the moisture helps limit damage to your foundation and your belongings.

How to Keep Your Basement Dry

There are several ways to keep a basement dry. These are the main ones.

Stay on Top of Repairs

Large cracks in your foundation wall can allow water to seep through from the outside. Watching for foundation damage and keeping up with regular repairs can make it less likely that foundation damage will lead to water in your basement.

Look Into Waterproofing

Interior basement waterproofing manages the water that reaches the basement walls and floor and carries it out of the house, which helps keep the basement dry.

Rely on Dehumidification

Another excellent tool for maintaining basement dryness is a dehumidifier. Whether you have had moisture issues in the past or not, dehumidification will help you monitor and control the relative humidity in your basement.

Install an Interior Drainage System

An interior basement drainage system collects water along the inside of the foundation and carries it to a sump pump, which sends it out of the house. It helps a basement handle heavy rain and high groundwater.

Need Help Keeping Your Basement Dry?

There are ways to both prevent and fix basement water problems, and a professional inspection is a good place to start. HydroHelp911 provides structural foundation repairs and waterproofing across North and South Carolina and can find the source of the water in your basement.

How to Fix a Sticking Door

Cory Parks — Mon, 08 Jan 2024 09:00:27 GMT

To fix a sticking door, start with the simple causes: clean the door and frame, tighten or replace loose hinges and latches, and lower the humidity if the wood has swelled. If the door keeps sticking after those, and especially if other doors and windows stick too, the cause may be foundation movement, which a foundation inspection can confirm.

This article covers the causes of sticking doors and how to fix each one.

Why Does a Door Stick?

There are several reasons a door can stick, and some are much easier to fix than others.

Your Sticking Door Is Dirty

The simplest cause of a sticking door is that your door is actually sticky in a literal sense. Over time, your doors can accumulate dust and filth just like any other surface. If enough sticky filth accumulates, it may cause your door to stick to the threshold each time you close it.

Fortunately, the fix for this kind of sticking door is straightforward. Simply give your door a thorough cleaning, and it should become unstuck. If it doesn’t, you’re likely dealing with one of the following sticking door causes.

Your Sticking Door Is in a Humid Location

Relative humidity can also cause a door to stick. Materials like wood tend to expand and contract based on the amount of moisture in the air.

When the air in your home becomes more moist than usual, your doors may start to swell. While this swelling is not often something you can see with the naked eye, it is enough to cause your door to fit improperly in your door frame.

Your Sticking Door Was Installed Improperly

Another cause of a sticking door is improper installation. Although it seems like installing a door correctly should be an easy task, there is plenty that can go wrong during the process. Whether the hinges, the latch, or any other part of the door experienced an incorrect installation, you’ll likely notice right away when your door fails to open and close properly.

Your Sticking Door Has a Broken Hinge or Latch

Even when your door is installed correctly, it remains possible for it to become damaged later on. When the hinges or the latch of your door begin to break down, one of the first signs will be that the door starts to stick.

Loose hinges cause a door to hang at a slight angle, making it difficult for it to fit correctly into its frame. Similarly, latch malfunctions can make it tough for you to turn the door’s handle and open it easily.

Your Sticking Door Is a Sign of Foundation Movement

If none of the causes above fit, a sticking door may come from foundation movement that shifts door frames.

When a foundation settles unevenly, the house can shift slightly out of square, including the door and window frames. This cause needs a professional to find and repair.

How Do You Repair a Sticking Door?

Each fix below matches one or more of the causes above.

Fixing the Door Itself

If your door is stuck because of a faulty installation, broken hinges, or a malfunctioning latch, the odds are that you can take a DIY approach to fix it. Repairing a door is not all that difficult to do, and does not require many specialized skills.

Instead, with a simple set of tools, you can either repair or replace the elements of your door that are causing it to stick. If a replacement is necessary, you’ll be pleased to know that hinges, latches, handles, and other hardware pieces are commonly available in many stores.

After determining which component of your door needs repair and gathering your necessary supplies, you shouldn’t have too much of an issue unsticking your door on your own. Of course, if DIY is not your preference, you can always hire a repair person to fix your door, which is unlikely to be a costly expense.

Adjusting Relative Humidity

At times, your sticking door may be the result of high relative humidity. This issue is most common in climates that are naturally humid, or during the summer months in areas that are otherwise not that humid.

Again, the solution to this sticking door cause is quite simple. In many situations, all you will have to do is find a way to lower the relative humidity in the area surrounding your door. Often, running a dehumidifier is enough to resolve this problem.

Foundation Repair

When the other fixes have not worked, the sticking door may come from foundation settling.

That is not a DIY repair. A foundation inspector can evaluate your foundation and recommend the foundation repair solution that fits, such as piers to stabilize a settled area.

Getting Your Doors Unstuck

As you now know, a door can become stuck for one of several reasons. Each of those causes calls for a different repair approach. While it’s reasonable for you to fix some of those causes on your own, other causes require the help of a professional.

If you have cleaned the door, repaired it and adjusted the humidity and it still sticks, a foundation team can help. At HydroHelp911, we evaluate and repair foundations across North and South Carolina, starting with a free inspection.

Is Crawl Space Encapsulation Worth It?

Cory Parks — Tue, 02 Jan 2024 09:00:05 GMT

Crawl space encapsulation is often worth it when a crawl space has moisture, mold, musty odors or pests, because it addresses the moisture that causes those problems. Whether it is worth it for your home depends on the condition of your crawl space and what the work costs, which a free inspection shows.

Encapsulation seals the crawl space to help keep it clean and dry. This article covers its benefits, what it costs and the signs that point to it.

What Are the Benefits of Crawl Space Encapsulation?

Crawl space encapsulation has several benefits. These are the main ones to weigh against the cost.

Moisture Control

The main purpose of crawl space encapsulation is to control moisture in the crawl space. A liner covers the floor, foundation walls and piers, so ground moisture stays behind the barrier. Keeping moisture out reduces condensation and humidity, which leads to the benefits below.

Reduction of Mold and Mildew

Less moisture in the crawl space discourages mold and mildew. Mold and mildew can damage wood in the crawl space, and the EPA notes that mold can trigger asthma episodes in people with asthma. Controlling moisture helps prevent mold.

Pest Prevention

The barrier that keeps moisture out also helps keep pests out. An open, damp crawl space can give insects and other animals a place to settle.

Pests can cause damage that needs repair later. Encapsulation helps make the crawl space less inviting to them.

Protecting the Wood Structure

Moisture in a crawl space can cause wood rot, which can weaken the wood supports over time. Encapsulation helps protect that framing from moisture.

Usable Storage Space

An encapsulated crawl space can also become a cleaner, drier place to store some belongings. Without encapsulation, damp crawl spaces are often a poor place to keep anything.

Energy Efficiency

Encapsulation can also help your home use energy more efficiently. A sealed crawl space lets less outside air in under the house, which can help your heating and cooling systems work less to keep the rooms above comfortable.

How Much Does Crawl Space Encapsulation Cost?

There is no single average crawl space encapsulation cost: the price depends on the size of the crawl space and the work it needs. The crawl space encapsulation page shows the range HydroHelp911 publishes for it. The price for your home is set in a written estimate after a free inspection.

What moves the price within that range:

The size of the crawl space
Its condition, such as standing water, old insulation or debris that has to come out first
Whether it also needs an interior drainage system, a sump pump or a dehumidifier

For a ballpark figure before an inspection, try our cost calculator.

Many homeowners find the benefits outweigh the cost, because controlling moisture can help prevent problems that would need repair later.

What Are the Signs You Might Need Crawl Space Encapsulation?

Encapsulation can be a preventive step even when a crawl space has no problems yet. These signs mean it is worth considering:

Standing water in your crawl space
Excess moisture in the form of humidity or condensation
Visible mold and mildew
Signs of pests
Musty smells that reach the rooms above

When moisture and pests go unaddressed, they can lead to damage that is costly to repair. Encapsulation is one of the ways to help prevent it.

Common Questions About Crawl Space Encapsulation

How Much Does Crawl Space Encapsulation Cost?

The price depends on the size of the crawl space, its condition and whether it also needs drainage or a dehumidifier. The crawl space encapsulation page shows the range HydroHelp911 publishes for it, and your free inspection gives you a written estimate for your home.

Does Crawl Space Encapsulation Need Maintenance?

Yes. The lifetime warranty on an encapsulation liner requires annual maintenance at the owner's expense, and our annual maintenance program is $250 a year. The full terms are on our warranties page.

Is a Vapor Barrier the Same as Encapsulation?

No. A basic vapor barrier usually covers the ground only, with overlapped seams. HydroHelp911 full encapsulation covers the ground, foundation walls and piers, with every seam taped.

Should You Worry About Sloping Floors in Older Homes?

Cory Parks — Tue, 26 Dec 2023 09:00:38 GMT

Whether you should worry about sloping floors in an older home depends on what is causing the slope. Sloping floors are common in older homes, and many come from years of gradual settling that is not a structural problem on its own. A slope that comes with sticking doors and windows, wall cracks or stair step cracks in masonry can point to foundation damage or decayed floor framing, and an inspection shows which you have.

This article covers why floors slope in older homes, when it matters and how sloping floors are repaired.

Why Do Floors in Older Homes Slope?

Sloping wood floor in an older home

Generally, sloping floors are more commonly found in older homes than newer ones. The reason for this is that it typically takes a considerable amount of time for a floor to slope to the point that it is easily noticeable.

For example, some sloping floors are the result of accumulated damage or decay to the structural components that support the floor. This is especially true of wooden floors, as rotted joists and broken boards can all cause a floor to become unlevel.

However, there are many instances in which the cause of a sloping floor has nothing to do with damage to the floor itself. Instead, many sloping floors in older homes arise as a result of settling.

After a house is built, it is common for the soil below the house’s foundation to shift gradually over time. This is most prevalent when the soil has not been properly compacted, meaning that it has many small pockets of air within it.

Since the soil supports the foundation, and thus the rest of the house, if it shifts or sinks, the foundation will usually shift or sink to the same degree. A small amount of settling is to be expected, but some houses settle far more dramatically than others.

In many older homes, enough settling has occurred over the decades that the entire house has become uneven. The slope of a floor is often one of the easiest ways to recognize that unevenness.

An older home settling is not something that should cause concern on its own. Despite being uneven, a settled house is not necessarily structurally unsound, meaning that a sloping floor is also not necessarily something that should cause immediate concern.

But with that said, a sloping floor can also be a sign of foundation damage. A damaged foundation can cause a similar shifting effect as normal settling does. It can also result in sloping floors.

So a sloping floor alone does not show whether an older home has a structural problem, and it is hard to judge on your own. An inspection can find the cause of the slope and whether it needs repair.

How Much Slope Is Too Much?

Some signs anyone can look for suggest a slope is worth checking: windows and doors that stick, cracks in walls and stair step cracks in masonry. These often point to a deeper cause.

The amount of slope matters too. Some slopes are so slight you may not notice them, while others are steep enough to trip on. There is no single number that decides it. If a slope bothers you or is getting worse, an inspection can tell you what is causing it and what a repair would involve.

What Can You Do About a Sloping Floor?

If you decide that your floor is sloping enough to require a repair, the next step is to figure out what kind of repair is necessary. Remember that a sloping floor can occur due to one of several potential causes, each of which can call for a different solution.

For example, we mentioned earlier that some sloping floors result from damage to the floor itself or the floor’s supporting structures. In most cases, solving these kinds of sloping problems comes down to replacing the materials that have become damaged or decayed.

If the slope comes from a foundation problem, new flooring will not fix it. The repair is in the foundation, such as foundation underpinning or new supports under the floor framing, which can help bring the floor back toward level from below.

Whatever the cause, a professional inspection finds it, and the repair is matched to it.
