Wet/Moldy Crawl Space?

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.

SPECIAL NOTE: Closing air vents in a crawl space may create a dangerous carbon monoxide problem in your home. Before sealing any air vents in a crawl space, contact a local HVAC Contractor. Air vents can not be closed if gas fired equipment draws fresh air for combustion from the crawl space. An HVAC Contractor can suggest alternative ways to get fresh air where needed. If in question or there is any doubt DO NOT CLOSE AIR VENTS!!!
