Sistering Floor Joists in Charlotte, NC & Nearby Areas

Sagging floors, cracked subflooring, or weak structural framing are more than just annoyances—they’re signs your home or building may be dealing with floor joist failure. Over time, moisture, overloading, or age can cause joists to weaken, especially in crawl spaces and basements. Ignoring these signs can lead to uneven flooring, structural instability, and expensive long-term damage.

Sistering floor joists is a reliable solution that strengthens compromised joists without complete replacement. Instead of tearing out old supports, a new board—often an engineered wood like an LVL—is added alongside the damaged joist. This floor reinforcement method distributes weight more effectively, reducing bounce and preventing further sagging. It’s an excellent option for structures with overspanned joists or localized damage.

HydroHelp911 specializes in floor joist reinforcement solutions tailored to your home or building. Our experienced technicians assess how severe the damage is and use advanced sistering joist techniques to restore floor strength and stability.

Step-by-Step:

Our Sistering Floor Joist Repair Process

Identify the Problem If you’ve noticed your floors sagging, bouncing when walked on, or sloping toward the center of a room, it could be a sign of failing or overspanned floor joists. In crawl spaces and unfinished basements, you might also see cracked joists, separation at framing joints, or signs of rot. These issues compromise your property’s structure and can worsen without timely repair.
Our Solution HydroHelp911 uses professional sistering techniques to restore floor integrity without removing your existing framing. We create a stronger, unified support system by installing a new joist—called a “sister”—next to the damaged one. This method adds stability, distributes load more evenly, and strengthens your floor structure for years.
Step 1: Our team at HydroHelp911 performs a thorough inspection of your framing. We assess load requirements, span lengths, and check for moisture damage, wood rot, or existing structural shifts. This helps us determine if floor beam reinforcement or additional support is necessary.
Step 2: Next, we select the proper material for sistering—typically an LVL or dimensional lumber—to match or exceed the strength of your current joists. We secure the new joist using bolts, lag screws, and structural brackets, ensuring a tight, durable connection.
Step 3: We also install supplemental floor jacks or beams to lift sagging areas and lock everything into position if needed. This repair approach not only fixes the damage but also prevents it from coming back.
