Before encapsulating this crawl space, we treated the joists with an antimicrobial called Shockwave. This product is a hospital-grade antimicrobial designed to kill the mold and mildew growth.
Mold needs warm temperatures, high relative humidity and organic material to grow. In our area, crawl spaces create the perfect environment for this. We did a physical wipe down of the joists with an antimicrobial to kill and remove the mold growing on the wood.
Fiberglass Batts between the joists absorb moisture like a sponge. They hold moisture against the wood joists and fall and sag over time. Their paper backing and the wood floor joists are organic material that often has mold growing on them. We removed the old insulation and installed new, foam board insulation on the crawl space walls.
Previously, this crawl space had a 6-mil lightweight vapor barrier that was torn and even missing in places. We installed the CleanSpace Encapsulation System. The CleanSpace vapor barrier is a heavy-duty 20-mil liner that is perfect for crawl spaces that have service persons working on equipment, plumbing, or electrical, or for storage. It resists rips and tears, and is fastened to the walls and wrapped around piers sealing the earth off from the home.
This Bruington, VA client contacted us about repairing moisture damage in their crawl space. Moisture had caused mold and mildew growth, was absorbed in the insulation which held it against the floor joists, the material began to delaminate and fall away from the floor.
All debris and insulation was removed from the crawl space, microbial growth was treated, the vents, sill plate, & rim band were sealed, the foundation walls were insulated with closed cell spray foam insulation and a dehumidifier was installed to control the relative humidity. The homeowners no longer need to worry about moisture damage in their crawl space and have the added benefit of warmer floors in the winter and reduced drafts in the home.
