Structural & Subfloor Repair in Chattanooga, TN

The framing under your floors carries everything above it. When moisture rots joists or termites weaken them, floors sag and bounce. We sister, replace, and reinforce damaged framing to make floors solid again.

Why it matters in Chattanooga

Structural & Subfloor Repair for Tennessee Valley Homes

Sagging or bouncy floors usually trace back to the crawl space or basement below: joists weakened by years of moisture, subfloor softened by rot, or framing that was undersized or over-spanned from the start. Chattanooga's humid climate and vented crawl spaces make moisture damage the most common cause we see.

Repair starts with understanding the full extent. We inspect every joist, beam, and subfloor section — because rot hides, and fixing only the visible damage invites a repeat. Damaged joists are sistered with new lumber or replaced; compromised subfloor is cut out and renewed; additional supports or beams are added where spans are too long.

Structural repair pairs naturally with moisture control — there is little point rebuilding wood that will rot again. We will tell you honestly whether encapsulation or drainage should accompany the framing work, and lay out the complete plan in writing before anything begins.

Questions

Structural & Subfloor Repair — FAQs

What does 'sistering a joist' mean?

Attaching a new joist alongside a damaged one to restore strength — the standard repair for partially rotted or cracked joists.

Do you have to tear up my floors?

Most structural work is done from below, through the crawl space or basement. Interior flooring usually stays intact.

Is this related to foundation settlement?

Sometimes — settlement can stress framing, but moisture damage is the more common cause in this area. Inspection determines which.

Should I also encapsulate the crawl space?

If moisture caused the damage, controlling it is essential to protect the repair. We will give you an honest recommendation.
