A musty smell has been creeping out of the bathroom wall for weeks, and now a patch of drywall feels soft and damp. The culprit is almost certainly mold taking hold behind the drywall, right where the plumbing runs from the sink. Those tiny leaks from the pipe connections, nothing dramatic, just a slow steady drip over time. It's created the perfect hidden environment for mold to thrive, growing unseen inside the wall cavity, feeding on the paper facing of the drywall and the wood studs.
