Floor Joist Repair

Floor joists carry everything above them. When one cracks, rots or is notched for plumbing, the floor above bounces or sags, and neighboring joists take on extra load. The sooner it is repaired, the less likely it is to spread.

We repair floor joists in crawl spaces across Nashville and Middle Tennessee. Damaged members are sistered with new lumber, bolted or fastened properly and supported so the load is carried as it was meant to be.

What you get

Done right, from the first walk-through

01

Damaged joists sistered

New lumber is fastened alongside the original along its full length.

02

Bridging and blocking

Cross bracing keeps joists from twisting and spreads the load.

03

Support at the weak point

Posts or beams added where the span is too long.

04

Moisture source corrected

Rot is not repaired and left to return, so the cause is handled too.

The process

How your service comes together

  1. 1

    Check the framing

    We probe and measure joists and note which are damaged and why.

  2. 2

    Repair and reinforce

    Joists are sistered or replaced and supports are added.

  3. 3

    Seal the source

    Moisture or pest entry is corrected so the repair lasts.

FAQ

Common questions about floor joist repair

Can one bad joist be repaired by itself?

Often yes, if the rest of the framing is sound. We check nearby joists and the subfloor before deciding.

Why do floors bounce?

Long spans, undersized joists, cracked or rotted wood and sagging supports can all play a part. Inspection shows which applies.

Will floors be level after the repair?

Repairs restore strength and often improve levelness. Where the floor has sagged, we may add jack posts or beams to lift gradually.
