Crawl Space Dehumidifiers

High Levels of Moisture in the Crawl Space Causes Big Problems in the Home

High humidity levels in the crawl space lead to condensation, mold growth, musty odors, pests, water damage, and ultimately, structural damage.  Mold and dust mites thrive in humid environments. Mold spores and dust mite droppings are the two main causes of indoor allergies in the U.S. and these polutants will not stay in the crawl space. The air in any building moves upwards, so they will seep into your crawl space. In fact, recent developments in building science found that an average of 2/3 of the air you breath in your home, comes straight from your crawl space. 

That is why it is important to keep crawl spaces sealed and as dry as possible, using a crawl space dehumidifier. 

Dehumidification: The Definitive Solution for Crawl Space Mold Problems


Using a dehumidifier in your crawl space has multiple benefits. These include decreasing the moisture in the air and improving the air quality, preventing  mold growth, and keeping your encapsulated crawlspace dry. Also, by placing a good commercial dehumidifier in your crawl space, you can condition your indoor air and reduce your family’s exposure to health issues.

Dehumidifiers can also benefit the whole house, not just the crawl space. By reducing humidity, they also help save on energy costs, and even lengthen the lifespan of your HVAC system.
