Pattern matters
Damage after shower use differs from staining below a plumbing connection.
Moisture source first
Replacing caulk, drywall or trim without finding the moisture path can create repeat work.
Ventilation is a system
Fans, duct routing, make-up air and how the room is used all affect moisture removal.
Hidden damage can expand scope
Once wet finishes are opened, the contractor may find a larger affected area than the visible surface suggested.
