Use our crawl space products, air vents and doors to ventilate your crawl space with natural air flow or forced air with our energy efficient exhaust and portable fans. Natural air flow and forced air flow cost less than a dehumidifier.

Moisture in the crawl space rots the wood under your home. Reduce the moisture in your crawl space with our crawl space doors, louvers, flood vents, and portable exhaust fans.


A damp crawl space is unhealthy. Mold thrives in damp areas, causing millions of airborne mold spores to enter your home. Toxic mold spores can be deadly to children, folks with allergies, and people with COPD.


Reducing the moisture in your crawl space reduces mold that releases airborne mold spores into the environment.


Our durable ABS / UV treated plastic will not rust or rot like wood or metal doors. Easy to install. No mortar required. Mount door frame over opening drill through frame into mortar and screw onto foundation.
