Frequently Asked Questions
Look for water stains, mold spots, chalking, or peeling paint on walls—these indicate damaged waterproofing. Press the wall to feel for soft areas. Multiple or severe leak points need immediate repair. A contractor should inspect to confirm damage extent and repair approach.
Surface-only repairs may fail again. Proper repair requires identifying and fixing the leak source—often window frames, balconies, rooftops, or upstairs units. Complete repair addresses both the source and waterproofing layer. Request a warranty period from your contractor.
