HOW WE WORK
Fix the Cause, Then the Deck
We open floors surgically, sister or block compromised framing, and install new decking glued and screwed to eliminate movement. Panel seams land on framing, gapped and fastened to spec.
Where moisture caused the failure, we verify the source is corrected and readings are in range before closing up, because replacing a subfloor into the same wet conditions just schedules the next failure.
