mold behind drywall near plumbing 7

https://writerhavenx.com/s/SWZPKdYRb4TAGJFRCgdNC

A persistent musty smell near the laundry room led me to cut a small hole in the drywall, and sure enough, there was black mold creeping along the backside right where the drain pipe runs. The moisture from a slow leak had been feeding it for months, hidden behind the wall. This is the kind of mold problem you can't just clean with bleach—the drywall needs to be removed, the plumbing fixed, and the area properly dried out before closing up again.
