BRS Pros did quite a bit of work for Wendy. Here are some steps we took…
Concrobium – is a 2-Phase EPA registered “Green” stain cleaner and mold killer. Phase I (CSR) was sprayed on the wood components throughout the crawl space which will clean some of the stains. However, deep pre-existing stains on damaged wood members will be visible after cleaning. The biodegradable ingredients will further break down into safe by-products which are mostly odorless and pet friendly. However, some odors may be realized in the home for several hours. The proprietary solution employs liquid oxidative technology to facilitate physical mold removal but contains none of the harsh chemicals associated with traditional oxidation products such as VOC’S, chlorine, bleach and ammonia. After cleaning, Phase 2 consists of fogging the complete crawl space with CMC that crushes, encapsulates and kills up to 99.9% of remaining organic growth mold spores in the crawl space.
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 plates (rim joists) 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.
Hydra-Channel – A clean trench was dug along the full interior perimeter of the crawl space foundation. The Hydra-Channel will be installed according to manufacturer’s instructions adjacent to the footer. The Hydra-Channel engineered fusion welded high strength polyethylene water system will remove storm water up to 70% faster than a traditional pipe and stone system, allowing water to flow freely to the in-ground sealed sump pump/basin. The Hydra-Channel system will carry a five year transferable warranty to prevent water on top of the ground liner where installed.
Sump Pump – Installed the Grate Sump basin with removable (flush with floor) lid covered with stone in crawl space. The system includes 1/3 HP cast iron primary pump with dual float cage that protects debris from float. Included is deluxe controller that monitors 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.
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.
Wall Liner – Installed our 9-mil white 100% woven reinforced wall liner in the crawl space. 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.
Fiberglass Blanket – 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 cover wall to approximately 4″ off the ground.
Floor Liner – 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 will be nailed/sealed approximately 6″ to 12″ above the earth in the crawl space to the foundation wall. A radon piping system will be 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 “crawlspace 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 E100 “Energy Star” rated dehumidifier delivers 23% annual energy savings above conventional products, a high-capacity solution designed for humidity control in crawlspaces and basements. The Model E100 potentially can remove up to 95 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 Wendy make her new home happy, healthy, & safe!
