Joist Replacement for Pier & Beam Homes

Floor joists are the framing members that span between beams and support the subfloor above. When joists weaken, rot, or split, the floors in a pier and beam home can start to bounce, sag, or feel uneven. Brown Foundation Repair replaces failing joists and reinforces weakened areas to restore strength and stability to the floor system.

Joist replacement is often part of a broader crawl space subfloor and wood replacement project, especially in homes with long-term moisture issues or high humidity under the house.

Signs of Joist Problems

Common signs that joists may be damaged or under-performing include soft spots in the floor, noticeable bouncing when you walk, or areas where furniture seems to lean or rock. In some cases, you may also see cracks in walls or gaps at baseboards directly above troubled joist areas.

During a crawl space inspection, our project planners look for rot, insect damage, improper notching, over-spanning, or joists that have been altered to accommodate utilities.

Our Joist Replacement Process

When joists must be replaced, we carefully support the affected area, remove the damaged members, and install new joists of appropriate size and spacing. In some situations, we may also add sister joists alongside existing ones to reinforce the structure without full removal.

Joist replacement is frequently paired with wood beam replacement or crawl space adjustments, ensuring that new joists are supported correctly and that the floor system is properly leveled.

Benefits of Proper Joist Support

With properly supported and sized joists, floors feel more solid, and the home is better able to handle normal use and seasonal movement. Correcting joist issues also helps protect flooring finishes and reduces the risk of ongoing cosmetic cracking.
