You pull back a section of drywall near the bathroom plumbing and find black splotches and a musty smell that's been getting worse for weeks. The mold is thriving in the damp space behind the wall, where a slow drip from a pipe joint has kept the wood and gypsum wet. It's not just surface-level either—it's spread into the insulation, and the spores are probably drifting into the room through gaps around the baseboard.
