Crawl Space Encapsulation in Round Hill, VA Crawl Space Encapsulation in Round Hill, VA

The homeowner in Round Hill, VA called us because she had old in the crawl space. The first challenge for this Round Hill home involved removing all of the old moldy insulation and vapor barrier. We found a plethora of wildlife both alive and dead under this house. Once the moldy materials had been removed and disposed of, we had to clean the crawl of debris. The HVAC equipment and ducting system was cleaned out and rid of mold and mildew.  We then used a hydrogen peroxide spray to kill all of the mold and mildew on the joists, and crawl space walls.  Comfenergy encapsulated the HVAC duct work using closed cell foam spray to seal it from leakage and insulate it properly once and for all.  Then, we encapsulated the crawl space which makes it basically become part of the conditioned space within the home. TerraBlock insulation infused with hypo-allergenic materials was installed on the dirt floors to provide an insulation value.  A thick 20 mil CleanSpace barrier was installed over top of the TerraBlock to provide a moisture barrier and keep things dry now that the mold had been removed. Foam board insulation was installed on the walls of the crawl to kep it more like the temperatures of the rooms above.

Fiberglass batts allow hot/cold air around and through making the rooms behind hot/cold too.  Foam spray can be used to fix this issue!

24 year old house.
Bloomfield Road in Round Hill
We have unusually high electric bills in the winter and would like to check for a remedy, like possibly more insulation or changes to heating system.
Scotland Heights Road in Round Hill
We have recently renovated a historic home, 1/2 log cabin and 1/2 stone structure. There is a crawl space under the log structure with our heater and water heater that is not insulated. The area under the stone structure has only very minimal crawl space and is not insulated. We have noticed a moldy/damp smell and also lots of insects, mice, etc. We wonder if proper insulation could help with all of the above.
