More than 70+ million homes in the United States are built on crawl spaces. Houses are built on crawl spaces because it is cheaper than basements or because ground conditions make building a basement impractical. In most climate zones, properly designed, installed, and conditioned closed crawl spaces can work well. You might not offer encapsulation as part of your current business model, but you are most likely often in crawl spaces that have already been closed or encapsulated. You can observe if the best “conditioning” method (a commercial- grade dehumidifier) to control the moisture to a specific relative humidity (RH) setpoint is being used during your visits. If not, you have the opportunity to offer this service and add revenue to your business.
Effective moisture control in a closed crawl space is essential for protecting the home and the homeowners. High humidity levels in a home encourage mold, mildew, odors, unhealthy air quality, damage to the home’s structure, and even pest problems. Common pests such as termites, wood-boring beetles, fleas, mosquitoes, ants, silverfish, spiders, and cockroaches thrive in high humidity.
