The Drying Co. Before & After Photos

As part of air sealing and insulating their attic, this home had several recessed lights or "can lights." These lights are a HUGE culprit of conditioned air loss in a home. To air seal these lights while protecting the insulation from the heat the housing can give off, we use rockwool can light covers that are sealed with foam. 

While it's often hard to see what dense packing between floors or exterior walls looks like, these photos show how our techs access the floor (or wall) cavities to fill them with cellulose insulation. A hole is made to fit the hose and then our technician packs the floor cavity with insulation. when complete, this makes a big difference in heat transference for the room above the garage, keeping it cooler in the summer and warmer in the winter. 

We installed about 1.5 inches of closed-cell spray foam over the foundation walls of this crawl space in Glen Allen, VA. At this thickness, the spray foam has an R10 value of insulation and acts as an air barrier and vapor retarder. We blocked out any open vents running along the crawl space wall, as these vents allow outside air and moisture to freely enter to crawl space, affecting the environment and relative humidity. With any insulation we install over the foundation walls, we always leave a 2-inch viewing strip at the top of the wall for termite inspectors. With these solutions in place, the crawl space is better protected from any outside influence penetrating through the foundation walls.

This homeowner was experiencing moisture issues within their crawl space. With open vents lining the porous foundation walls and many areas of the floor remaining exposed, this crawl space was being affected by the outside air and moisture, as well as the moisture rising from earth. This influence can affect the environment and the relative humidity of the crawl space. An elevated relative humidity can lead to condensation, puddling, and mold and mildew growth. Our installers placed a heavy-duty 20mil vapor barrier, called CleanSpace, over the dirt floor of the crawl space. It is wrapped around all piers, sealed with vinyl tape, and mechanically fastened to the foundation walls six to eight inches above outside grade. This liner will assist in sealing off any moisture rising out of the earth. It is one of many solutions when fully sealing and encapsulating the outside off from your crawl space.

This crawl space had issues with mildew/mold, falling insulation, an ineffective vapor barrier, and moisture concerns in the home. We removed the old insulation and vapor barrier, treated the mildew/mold, installed a new vapor barrier, applied spray foam insulation on the crawl space walls, sealed all the vents, the rim and band, and sill plate, and insulated behind the crawl space door, then installed a dehumidifier to control relative humidity.
