Why Ventilate the Crawlspace?

Why Ventilate the Crawlspace?

The presence of moisture is what leads to mold, which can be bad for your health
and costly to remove. According to the Environmental Protection Agency, the way to control mold is to control moisture. The main source of crawl space moisture is ground evaporation, and ventilation allows this evaporation to dissipate. Proper ventila- tion not only exhausts moisture from the crawlspace but replaces it with fresh, drier air providing effective moisture control. Ventilation also helps to remove strong odors and dangerous radon gas from the crawlspace.

The benefit of an Exhaust Fan

Exhaust Fans pull air out of the crawl space and removes radon, odors and moisture. Exhausting crawl space air removes the bad air and brings in fresh air from the outside environment. Bad or stagnant air in the crawl-space seeps into the home through cracks in the floor, which can cause health problems in asthmatics and children.
