BRS Pros helped John and here are some steps we took…
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. 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.
Sump Pump – Installed our Grate Sump basin with a removeable (flush with floor) lid covered with stone in right front corner of crawl space. The system includes 1/3 HP cast iron primary pump with dual float cage that protects debris from float. Included is a deluxe controller that monitors the pump and power conditions and will sound an alarm if problems are detected or a high water warning in the sump. Additionally, it activates the pump weekly to exercise and extend the pumps life.
Blanket Insulation – We installed our 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.
9 Mil Wall Liner- Installed our 9-mil white 100% woven reinforced wall liner. The wall liner was mechanically fastened with nails designed for foundation walls to within 6″ of the top of the crawl space foundation wall to provide a complete future termite inspection unless indicated elsewhere. Mechanically fastening wall liner is a permanent solution opposed to just caulk or tape which will result in future maintenance or failure of the system.
15 Mil Floor Liner – We installed our Premium (walk on, store on) 15-mil white 100% woven reinforced radon ready crawl space system. The liner was mechanically fastened with nails designed for foundation walls to provide a permanent fastening system. (Caulking or taping liner to foundation walls is a temporary system and will become a maintenance issue.) The premium ground liner was nailed/sealed approximately 6″ to 12″ above the earth in the crawlspace to the foundation wall. 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. 15-mil woven ground liner will control moisture vapor and dampness from the ground. Most crawl space liners are partially reinforced, our woven liner is 100% reinforced and tough unlike competitive brand liners that are only 10% reinforced. This product will not off gas (known on Google as “crawl space cat urine odor”, go ahead and check it out), we guarantee it!! Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to the liner.
Dehumidifier – Aprilaire has been the industry leader in residential humidification control since 1954. The Aprilaire Model E070 Dehumidifier is a high-capacity solution designed for humidity control in crawl spaces and basements. The Model E070 removes up to 70 pints of moisture per day! Proudly made in the USA. Five year manufacturer’s parts warranty when installed by BRS Pros, an authorized installer for Aprilaire.
It was a pleasure helping John make this home happy, healthy & safe for the owners.
