Instead of a basement, some residential properties are equipped with a crawl space. This space is designed to provide access to plumbing, gas lines, and other important elements that run underneath the home. A crawl space can also act as a host for toxic mold. Since mold thrives in dark and damp areas, your crawl space can provide the perfect environment for mold growth. You need to be prepared to tackle a mold problem in your crawl space safely and quickly to avoid having the mold spread throughout your home.
