Damaged or Rotted Floor Joists in Murfreesboro, TN

Damaged or rotted floor joists are a serious structural problem that starts in the crawl space and works its way up into your living space. When moisture, fungi, or age weaken the joists that support your floor, the result is bouncy, sagging, or uneven floors — and the problem only gets worse over time. The Crawl Shield repairs, reinforces, and replaces damaged floor joists from the crawl space, restoring structural integrity without tearing up your finished floors above.

Frequently Asked Questions

Damaged or Rotted Floor Joists — Common Questions

How much does floor joist repair cost in Murfreesboro, TN?▼

Cost depends on the number of joists affected, the extent of the damage, and whether moisture remediation is needed. The Crawl Shield offers free inspections and fair, transparent pricing — call 629-295-3603.

Can rotted floor joists be repaired instead of replaced?▼

In many cases, yes. Sistering — attaching new lumber alongside the damaged joist — restores structural strength without removing the original joist. A free inspection determines the best approach for your situation.

Will fixing my floor joists from the crawl space damage my finished floors?▼

No. Joist repair and reinforcement are performed from the crawl space below, so your finished floors, tile, and walls remain untouched. Where lifting is appropriate, we adjust in careful increments to help minimize the risk of cracking or other finish changes.
