Diagonal Cracks in Your Walls? Your Foundation May Be Moving.

Diagonal wall cracks often indicate structural stress caused by foundation issues.

HydroHelp911 identifies the cause and fixes the problem at the source.

What Causes Diagonal Cracks?

Diagonal cracks are a common sign of foundation settlement or shifting. As one section of your foundation sinks or moves independently, the wall above it begins to tear in a diagonal pattern. Causes may include:

Uneven Foundation Settlement

Soil compaction, shrinkage, or erosion causes part of the home to sink

Hydrostatic Pressure

Water pushing against foundation walls creates uneven stress

Poor Soil Conditions

Expansive clay or improperly compacted fill

Aging or Inadequate Structural Design

Framing or supports not designed for long-term loads

When to Be Concerned

Some small cracks can result from material shrinkage. But diagonal cracks that are wide, long, or growing may point to serious problems:

Cracks wider than 1/8 inch
Visible displacement where one side of the crack is higher
Cracks appearing above door or window corners
Cracks reappearing after cosmetic repair

These indicators often signal active foundation movement.
