Basement & Radon Solutions, BRS Pros did some a bit of work for Pam & Norton. Here are the steps we took to help them.1. Mold Remediation: We started by removing all of the fungus/mold contaminated sub-floor insulation and moisture vapor barrier from crawl space and disposed of. The crawl space sub-floor wood components were then cleaned and deodorized for wood decaying fungi and organic growth. After cleaning an EPA registered fungicide is completely fogged throughout the crawl space. It will kill 99.9% of mold spores and will inhibit the growth of mold and mildew.2. Spray Foam: A Class A fire rated polyurethane closed cell spray foam insulation was sprayed on the rim joists and sill plates. It prevents air infiltration (unlike fiberglass insulation) and will insulate the wood band plate (rim joist) above the masonry foundation wall. Closed cell foam insulation (moisture and air will not penetrate this product) will fill and seal cracks, cavities and joints. Fiberglass insulation will not perform to prevent air infiltration. This product application will reduce cold spots in the floor adjacent to the main level walls.3. Foundation vents: The vents were completely sealed with poly-foam insulation from the interior of the crawl space preventing exterior air and moisture into the crawl space.4. Corrugated Pipe: A 4 suction pipe was installed. In the event the home is tested for radon in the future and found to be elevated, this component will be used with the additional exterior radon system to correct radon levels.5. Vapor Barrier (Wall): Installed 9-mil white 100% woven reinforced wall liner. Wall liner mechanically fastened/sealed to within 6″ of the top of the crawl space foundation wall.6. Fiberglass Insulation: Installed fiberglass blanket insulation on top of the white vapor barrier to the interior perimeter foundation walls. The insulation is 4″ thick which offers an R-13 insulation factor (code compliant for new construction). The insulation was hung approximately 6″ from the top of the interior masonry foundation wall to provide a termite inspection and will cover wall to approximately 4″ off the ground. 7. Dimple Shield: Installed our heavy duty 20-mil plastic dimple underlayment on the ground below the vapor barrier. It protects from puncture/wear and improves water movement due to the dimpled design. Adding the dimple drainage mat to our 15-mil reinforced ground liner gives homeowner 35-mil protection. 8. Vapor Barrier (Ground): Installed our Premium (walk on, store on) 15-mil white 100% woven reinforced liner. The premium ground liner was nailed/sealed approximately 6″ to 12″ above the ground to the foundation wall. The 15-mil woven ground liner will control moisture vapor and dampness from the ground. Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to our liner. 9. Aprilaire Dehumidifier: Aprilaire has been the industry leader in residential humidification control since 1954. The Aprilaire Model E100 Energy Star rated dehumidifier delivers 23% annual energy savings above conventional products. A high-capacity solution designed for humidity control in crawl spaces and basements. The Model E100 removes up to 95 pints (11 7/8 gallons) of moisture per day! Proudly made in the USA, and comes with a five year manufacturer’s parts warranty when installed by BRS Pros, an authorized installer for Aprilaire. 10. Lastly, a Hygrometer: Remote Temperature and Relative Humidity Meter stand alone unit with one remote sensor. The wireless remote sensor was mounted in the crawl space to give them an accurate reading of relative humidity. This product will help monitor the effective humidity of the dehumidifier in the crawl space.It was a pleasure making Pam & Norton’s home safe, happy, and healthy!”
