mold behind drywall near plumbing 26

After noticing a musty smell near the bathroom, I pulled back a corner of the drywall and found patches of black mold spreading behind it, right where the plumbing runs through the wall. The constant moisture from a slow pipe leak had been soaking the insulation and paper backing, creating the perfect hidden spot for mold to thrive without anyone noticing until the odor got strong.
