This Saluda basement had major water issues in the basement. The WaterGuard Drainage System and SuperSump were installed to help keep this basement dry ALL the time.
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.
Initially, this crawl space was encapsulated with a 6-mil vapor barrier and R-11 vinyl faced fiberglass insulation. Thhomeownerer contacted us with concerns about an ammonia, or animal urine odor in her home and poor air sealing.
Our goal was to remedy the Home Owner’s concerns of foul odors in her home and wasted energy. To achieve this, we installed a 20 mil Clean Space Vapor Barrier on the floor of the crawl space and around the piers. We installed Foamax board insulation on the walls leaving a 3-inch viewing strip for pest control companies to do their inspection. We applied spray foam insulation to the rim and band and sill plate to create an air seal and reduce drafts coming into the crawl space. Finally, we installed a Sani Dry Sedona Dehumidifier, the leading dehumidifier on the market, to pull any moisture that enters the crawl space out.
