About 27 million homes in the U.S. are built on a crawlspace. With 15 to 20 percent of new homes continuing to be built on crawl spaces, the number grows. Many crawl spaces develop problems including excessive moisture and all that comes with it: mold and mildew, wood rot, corrosion, poor indoor air quality, and insect and pest infestations. They also cause excessive energy loss, cold floors above, higher fuel bills, and greater wear and tear on HVAC equipment.
Most of these problems are due to one-size-fits-all building codes, cost-cutting construction practices, inadequate waterproofing, and insufficient air sealing and insulation. Fortunately, building scientists have revised their thinking about crawl spaces and have devised ways to eliminate or at least minimize the issues associated with crawl spaces. Codes are changing as well.
The practice of building dirt crawlspaces with open vents represents an older way of installing a crawlspace. Newer crawl space science debunks this old way of thinking. Explore typical crawl space issues and discover how your crawl space may be affecting your health and the indoor air quality of your home.
Crawl Space encapsulation reflects newer thinking on how to best improve the environment of a home's crawl space. Learn about options for controlling moisture, humidity and air quality in your crawl space.
