What Causes Musty Smells?
Musty odors are caused by the growth of mold spores. Mold spores are present everywhere, and when they land in a welcoming environment with moisture and food, they begin to multiply and emit gasses that our noses can detect.
Unfortunately, mold spores grow quickly, and it doesn’t take an extremely large colony to create odors. Small areas of mildew (fungi that appear flat on a surface) or mold (fungi that appear raised and usually fuzzy) should be cleaned away promptly and the area monitored to prevent return growth.
If the area of mold is extremely large, professional mold abatement may be needed. For small colonies of mildew on fabrics or walls, you can follow these tips to get the source of the musty smells under control.
