Too often, the crawl space is considered an after thought to homeowners. The fact is, however, air circulating through the crawl space can have a lasting impact on the overall air quality of your entire home. Leaving a dirty, wet and moldy crawl space unattended not only is a waste of potential storage space, but may have an effect on the health of your family. Sealing and insulating the crawl space provides a clean and usable area, protecting your family from radon gas, toxic mold, unwanted pests and harmful airborne allergens.
