A homeowner in Sterling, VA called as their house was hot in the summer and cold in the winter and wanted to make their home more comfortable all year.   We air sealed the attic floor with one part foam spray, then installed attic decking on the floor with plywood. We created plywood "dams" to keep the future cellulose insulation in place and off of the attic floor decking.  Finally, we created an attic hatch cover that was made o 4" thick SilverGlo foam boards, and blew in TruSoft cellulose insulation throughout.  The result the homeowmer will be warmer in the winter and cooler in the summer.

Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or will NOT work!

See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!!  This might have been the worst we have ever seen...Might be 2-3 feet of a gap!

Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable!

This sun room in Sterling, VA was too hot in the summer and too cold in the winter.  People spend a lot of money on these sun rooms and then can't use them because they aren't insulated well.  Comfenergy removed the fiberglass batts and installed closed cell spray foam to make it usable all year round!

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.

We have a 30+ year old home with original attic insulation. We are interested in having new insulation installed.
Riptide Sq. in Sterling
We are in the process of selling our home and during a recent home inspection, the inspector found traces of mice in the attic. The inspector found burrow holes, trails and droppings from mice in the insulation and we are currently in the process of contracting with an extermination company to find and kill the mice. Once that is complete, the buyers want to know how much it will cost to remove the compromised insulation, seal any entry point areas, inspect wiring and other attic components and replace with new insulation.
