Prevent Structural Damage from Spreading with Timely Joist Reinforcement
Weak Floor Joists Can Create Unsafe Conditions Across Your Home
When just one floor joist becomes compromised, the pressure is distributed unevenly across the subfloor. This leads to widespread sagging, squeaking, cracked drywall, and gaps between walls and flooring. Sistering floor joists stop this progression and restore the structure to its intended load capacity.
Common Joist Issues That Require Sistering Repair:
Existing joists have moisture damage or visible rot along the length
Floors are noticeably uneven, soft, or creaky when walking across
Joists are undersized or spaced too far apart during original build
Previous renovations have cut or notched structural members
Pest damage or termites have weakened critical framing connections
