Structural Wood Repair FAQs

How much does structural wood repair cost?

Structural wood repair in St. Louis typically costs $500-$3,000 depending on element type and damage extent. Sill plate repairs run $400-$1,200, joist repairs $300-$800 each, beam reinforcement $800-$2,500. Still saves 50-60% over full structural replacement.

Can rotted structural beams be repaired?

Yes, most rotted structural beams can be repaired using sistering (adding new lumber alongside), epoxy consolidation, or steel plate reinforcement. Our engineers assess each situation to determine the safest, most cost-effective repair approach.

Is structural rot covered by homeowners insurance?

Structural rot is typically not covered by homeowners insurance as it's considered gradual deterioration rather than sudden damage. However, if rot was caused by a covered event like burst pipe or storm damage, repairs may be partially covered.

How do you know if structural wood is rotted?

Signs of structural rot include bouncy or sagging floors, visible soft or discolored wood in basement or crawlspace, doors and windows that stick, cracking drywall, and musty odors. A professional inspection with moisture testing confirms damage extent.
