Let’s talk about indoor air quality and the factors that could affect it in your home. Multiple studies have shown that 40-60 percent of the air you breathe in your home comes from your crawl space. This is due to the natural stack effect that occurs in everyone’s home. Other causes that contribute to the stack effect are the opening and closing of your doors, your HVAC system cycling on and off, and any other activity or appliance that creates a pressure change within the envelope of your home.

For this reason, the condition of your crawl space should be a big emphasis for any homeowner. Keeping a clean, dry, and mold-free crawl space should be at the top of every homeowner’s list. By doing this, the indoor air quality will improve, as well as keeping the chance of termites, pests, and major structural damage to a minimum.
