Before & After Photos

Initially, this crawl space was encapsulated with a 6-mil vapor barrier and R-11 vinyl faced fiberglass insulation. Thhomeownerer contacted us with concerns about an ammonia, or animal urine odor in her home and poor air sealing. 

Our goal was to remedy the Home Owner’s concerns of foul odors in her home and wasted energy. To achieve this, we installed a 20 mil Clean Space Vapor Barrier on the floor of the crawl space and around the piers. We installed Foamax board insulation on the walls leaving a 3-inch viewing strip for pest control companies to do their inspection. We applied spray foam insulation to the rim and band and sill plate to create an air seal and reduce drafts coming into the crawl space. Finally, we installed a Sani Dry Sedona Dehumidifier, the leading dehumidifier on the market, to pull any moisture that enters the crawl space out. 

This crawl space was originally encapsulated at construction with a 6 mil Vapor Barrier and R-11 vinyl faced fiberglass insulation. The homeowner complained of an animal urine or ammonia odor in their home. This was a result of moisture entering the crawl space through the porous cinder block walls and saturating the fiberglass insulation. 

We installed a 20 mil Clean Space Vapor Barrier, Foamax Insulation Board, sealed the rim & band and sill plate, and installed a SaniDry Sedona Dehumidifier. This approach will help keep moisture out of the crawl space and control relative humidity. 

We replaced the vapor barrier within this Midlothian crawl space. The problem with the existing vapor barrier was that it had many gaps and holes within it, allowing the earth's moisture to rise into the crawl space. The moisture that becomes trapped within the crawl space will raise the relative humidity levels, leading to condensation in certain temperatures, and even mold or mildew growth. We replaced this inadequate liner with our own CleanSpace Light vapor barrier. The CleanSpace Light is a 10mil liner that covers the entire dirt floor of the crawl space, gets wrapped around each pier, and is mechanically fastened to the foundation walls six to eight inches above outside grade. A two-inch viewing strip is left at the top of the foundation walls for termite inspectors. This high-quality vapor barrier will help to reduce the earth's moisture from affecting the relative humidity of the crawl space, and it gives a bright, clean aesthetic to the crawl space.

A homeowner in Henrico, Virginia called us out to insulate and seal their crawl space from any outside influence. We installed a heavy-duty CleanSpace vapor barrier over the dirt floor, wrapped it around all piers, and mechanically fastened it to the foundation walls. This will help to keep the earth's moisture from rising into the area and increasing the relative humidity. We also covered any open vents and applied a spray foam over the foundation walls, which at an inch and a half thick will act as an air barrier and vapor retarder. With the walls and dirt flooring sealed and insulated, the crawl space will be less affected by outside air and moisture.

The original liner installed in this Henrico crawl space was a flimsy 6-mil vapor barrier. There were gaps in the liner, exposing the crawl space to moisture rising from the earth. This moisture can increase the relative humidity, which can lead to mold or mildew growth, condensation, and higher energy bills. We replaced this old liner with our 10-mil CleanSpace Light vapor barrier, which gets wrapped around all piers and mechanically fastened and sealed six to eight inches above outside grade on the foundation walls. CleanSpace will help protect the crawl space from moisture rising from the earth and comes with an antimicrobial, called UltraFresh, built into the material to help mitigate mold growth on the liner, itself.
