50% of the air you breathe in your home comes from your crawl space. Not only does mold effect your indoor air quality, and can affect your health, but it can cause structural damage to your home. Mold can promote wood rot on the joists of your home compromising its structural integrity. The high humidity and moisture that allow this mold to grow, also create an ideal environment for pests and insects. By not fixing this issue, it will only continue to get worse and become more costly to repair.
