Water damage and mold on ceilings can often look similar, but there are some key differences that can help you tell them apart. Water damage will typically have a darker, more discolored appearance than mold. It may also be accompanied by peeling paint or wallpaper, and the surface of the ceiling may feel damp or soft.
Mold, on the other hand, will typically have a more fuzzy or powdery appearance, and it may be accompanied by a musty odor. The surface of the ceiling may also feel dry and crumbly.
If you’re not sure whether you’re dealing with water damage or mold, it’s best to contact a professional for help. They will be able to accurately identify the problem and recommend the best course of action.
