There's a musty smell that's been getting stronger near the bathroom wall, and when I finally peeled back a corner of the drywall, I found dark, fuzzy mold spreading behind it, right where the plumbing runs through. The moisture from a slow pipe leak has been feeding it for months, and now it's creeping into the insulation.
