Mold Removal in Crawl Spaces

Crawlspaces are notoriously bad for mold growth, also included are cold cellars and storage rooms. These areas are not usually living spaces, simply just storage areas for personal belongings. If water or any source of water can enter the space, mould growth can and will occur. Mold will grow on the floors, walls, ceilings and anything else you have stored in the area.
