Many homes built on traditionally vented crawl spaces in Virginia and the southeast suffer from moisture control issues. Moisture comes from several sources including humidity, condensation, low-grade foundations with poor drainage, rising moisture from the ground and rainwater. Venting can’t remove it, in fact, it actually exacerbates the problem. The result is poor indoor air quality due to mold and microbial growth, high humidity indoors, wood rot, and insect infestations.
The solution is crawl space encapsulation. The result is maintaining the homes structural integrity, increased comfort levels and improved air quality. Therefore, encapsulation will probably soon become part of the building code for all new homes.
Step 1: Removal of any old insulation as needed.
Step 2: Apply a product to deodorize and sanitize the entire crawlspace that will eliminate bacteria, viruses, fungus, and unwanted musty odors.
Step 3: Bora-care™ Wood Treatment.
Step 4: Installation of insulation on all joist ends and on all exterior walls. The vents are sealed and we finish up by installing a vapor barrier on the floor, piers, and up the walls.
50% of the air you breathe in your home comes from your crawlspace. Research by Advanced Energy (sponsored by the U.S. Department of Energy), indicates that crawlspace encapsulation provides:
