A musty smell hits you as you walk down the basement stairs, the kind that clings to everything after a flood. The finished walls now show dark, creeping stains of black mold along the baseboards. Drywall is warped and peeling at the seams, and carpet squares near the sump pump feel damp even weeks after the leak was fixed. Spores dust the air, and the once-cozy rec room feels like a hazard zone.
