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.

Home Insulation Services You Can Trust!

Comfenergy is Nova's preferred home insulation and air sealing services company. We have helped many homeowners not only reduce their home energy bills but improve the overall comfort of their homes without patented home insulation solutions.  Did you know that most modern homes do not have adequate insulation? Because of this, your home may feel drafty or uncomfortable throughout the year, mostly in the summer and winter, and this can increase your home energy costs. Proper insulation in your home allows your heating or air conditioning systems to work more efficiently which will save you money. 

We offer a wide variety of home insulation products and services, and each one serves its own unique purpose.  Our most popular form of insulation is spray foam.  Spray foam insulation is extremely versatile and can be used almost anywhere in your home.  Spray foam insulation is one of the best ways to lower energy costs, sometimes 30% or more!

Along with spray foam, we use many other different types of insulation as well. Some of our other insulation products include rigid foam, blown-in, cellulose, fiberglass, radiant barrier, and much more.  We understand that insulation is only part of the home energy and comfort equation, so because of this, we can insulate any area of your home.  We insulate spaces such as attics, basements, crawl spaces, walls, floors, garages, and much more.  If your home is uncomfortable or energy bills are too high, contact us today for a FREE home insulation quote!

Expert Spray Foam Insulation Company

At one point pink fiberglass insulation was the best option for home insulation. However, today spray foam insulation is the much better option. Spray foam insulation has several benefits and beats the traditional fiber-glass product in every way. Spray foam insulation is the top choice for homeowners, contractors and building scientists (the experts who study home energy performance) for several reasons. Here are the top reasons spray foam insulation should be your number 1 choice:

Advantages of Spray Foam Insulation Include:

  • Provides both insulation and air sealing; air sealing is excellent because the foam expands to fill gaps and cracks.
  • High R-value -about R-7 per in. depending on the formulation.
  • Speedy installation. Foaming can be done in a fraction of the time it takes to cut, fit, and seal rigid board insulation.
  • Once cured, spray foam insulation stays in place; it won't shift, settle, or fall out of place.

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.

Heating bills are ridiculous for a one year old house. Thermostat set to 63/64 and still getting bills for multiple hundreds of dollars each month. We just want to see if there's anything else we can do to be more efficient (and hopefully spend less!) Thanks!
