Poor Air Quality

Naturally, the air from your crawl space flows into the living areas of your home. And it carries with it mold spores, moisture, and anything else that is airborne into your home. This natural upward movement of air is known as the stack effect. Home Energy Magazine estimates 40% of the air you breathe originates from the crawl space. A ventilated crawl space causes the stack effect, a continuous cycle that can cause myriad problems for your household.
