mold behind drywall near plumbing 83

A musty smell led me to check the wall near the bathroom plumbing, and sure enough, there was black mold creeping out from behind a loose section of drywall. The moisture from a slow pipe leak had been feeding it for who knows how long, spreading unseen until the paper facing started to bubble and discolor. It's the kind of hidden problem that can ruin your indoor air quality and rot out the framing if you don't catch it early.
