I noticed a musty smell in the bathroom and when I finally pulled back a section of the baseboard, I found black mold creeping up the back of the drywall right where the pipe comes through the wall. The leak must have been slow and hidden for months, and now the sheetrock is soft and stained, with that fuzzy mold spreading inside the wall cavity.
