When mold takes hold behind drywall near plumbing, it's often because of a slow, undetected leak that keeps the area damp. Over time, the musty smell becomes noticeable, and you might see dark spots or peeling paint on the wall surface. This hidden growth can damage the drywall and even affect air quality, so it's important to address the moisture source quickly.
