BRS Pros helped Ken with his crawl space and here are some steps we took…
Mold Remediation – Phase I of this work consisted of cleaning the crawl space sub-floor of wood decaying fungi and organic growth. After cleaning, Phase 2 consisted of fogging the crawl space. Phase II will kill 99.9% of mold spores and will inhibit the growth of mold and mildew. Decay and organic growth will be treated and cleaned, however, it is likely that some staining will remain due to any pre-existing damage to the wood members.
Spray Foam – 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.
Foundation Vents – Foundation vents were completely sealed with poly-foam insulation from the interior of the crawl space preventing exterior air and moisture into the crawl space.
Fiberglass Insulation & Vapor Barrier – Installed fiberglass blanket insulation with white vapor barrier to interior perimeter foundation walls. Insulation is 4″ thick which offers an R-13 insulation factor (code compliant for new construction). 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. A reinforced 9-mil wall vapor barrier was mechanically fastened to the foundation wall prior to fiberglass insulation to prevent any moisture/condensation from wall to contact insulation.
36 Mil Ground Vapor Barrier & Radon Ready – Installed our premium 36-mil ground vapor barrier custom designed for crawl spaces. A radon piping system was installed below the ground liner, the piping system will be used in the future when the home is tested for radon gas and requires a complete radon system. The padded felt bottom displaces ground water and soil gases, and is virtually puncture proof. The high-tech coating on this product has a glossy finish and is very flexible (not stiff like other reinforced vapor barriers). If you’re looking for the most advanced ground vapor barrier system this is it!

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.
