Basement & Radon Solutions, BRS Pros did quite a bit of work in John & Aimee’s crawl space. This is how it went…1. Removed all fungus/mold contaminated sub-floor insulation and moisture vapor barrier from crawl space.2. The crawl space sub-floor wood components were cleaned and deodorized for wood decaying fungi and organic growth. 3. After cleaning an EPA registered fungicide was completely fogged throughout the crawl space. It will kill 99.9% of mold spores and will inhibit the growth of mold and mildew.4. Our class A fire rated polyurethane closed cell spray foam insulation was sprayed on the rim joist 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.4. A 4 suction pipe installed in the crawl space. 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. Installed the fiberglass blanket insulation to the interior perimeter foundation walls. 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.6. Installed our 9-mil white 100% woven reinforced liner on the foundation wall. The wall liner was then mechanically fastened/sealed to the foundation walls.7. 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. Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to our liner.8. Installed the Aprilaire Model 1850 Dehumidifier is a high-capacity solution designed for humidity control in the crawl space. The Model 1850 removes up to 95 pints (11 7/8 gallons) of moisture per day! Proudly made in USA and comes with a five year manufacturer’s warranty.9. Lastly, we installed a Hygrometer. A 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 helping John & Aimee make their home happy, healthy, and safe!”
