Mold in drywall can be a serious issue, often hidden behind the surface and difficult to detect. Signs of mold include discoloration, a musty smell, or visible water damage. However, not all stains indicate mold; some may simply be from water exposure. It's essential to consider factors like the age of the drywall, the extent of moisture exposure, and the environment in which it’s installed. Regular inspections and proper ventilation can help prevent mold growth. If you suspect mold, it’s wise to consult a professional for a thorough assessment.
