No amount of mold in a crawl space is acceptable. Not only is mold an eyesore, it’s a threat to the structure of your home and to your health. If the support beams in your crawl space are growing mold, it’s likely they are damp and deteriorating. As the mold continues to infest your crawl space, it could mean allergies and more severe health problems for you and your family. If your crawl space has mold in it, it’s wise to have it removed as soon as possible.
