Improve Air Quality in Your Crawlspace and Home

The crawlspace plays an important part in the overall air quality of your entire house. When warm air in your house rises, it takes the air from the crawlspace with it. This isn’t a problem if your crawlspace is dry, but when moisture enters the crawlspace, it can encourage mold and mildew to grow.

As the air rises from the crawlspace, it takes these harmful molds and mildew from the base of your house and into your main living area. This can significantly reduce air quality by introducing allergens, mold and bad odors into the air you breathe every day. Not only is this issue annoying, it can be hazardous to individuals with asthma and mold allergies.


According to a study by the Mayo Clinic, nearly all chronic sinus infections are a result of mold. Since up to 40% of the air we breathe in the home can come from the crawlspace, mold in the crawlspace means mold in the home. The EPA recommends keeping humidity levels in the crawlspace to 40%–50% to reduce the likelihood of mold formation.
