Do Crawl Space Vents Work?

The purpose of crawl space vents is to allow air to circulate under the home to keep the crawl space dry. The problem is, crawl space vents do not work. They actually have the opposite effect: Creating even more moisture issues. During the hot summer heat in Texas, hot air comes in the crawl space through the vents, meeting the cool air under the crawl space. The mixing of the air allows for condensation and humidity to thrive. If it is raining outside, vents allow rain into the crawl space. If is cold outside, cold air is allowed in the crawl space (which makes flooring very cold in the winter). Simply put, you do not want outside air in the crawl space. Also, vents do not protect against water coming up through the ground into the crawl space, or from plumbing leaks.

Crawl space vents do not work, but there has to be a solution to keep crawl spaces dry. Allowing moisture to remain under a home leads to cupping hardwood floors, musty odors, mold growth, in home humidity, and heightened allergies and asthma while at home. Our solution is to seal off any outside air from the crawl space and turn the crawl space into a conditioned space. We do this by regrading the soil, installing a SmartSump sump pump, installing a drainage matting and CleanSpace vapor barrier, sealing off all outside air, and installing a dehumidifier. Our encapsulation system protects against outside air, groundwater seepage, and plumbing leaks.
