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:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call or click today!

Comfenergy is Northern Virginia'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?

Fairway Dr NE in Vienna
I live in a 1964 home and have noticed cold air coming from behind our kitchen wall over the past several winters. The interior wall is drywall; the exterior wall is brick. There is at least a 6" gap between the two. The overall wall size is 12 feet by 8 feet. You were referred to me by Dan of Quality Insulation, Silver Spring, MD. Apparently this job is too small for him. Would appreciate a call back and thanks!

Hot attic. Would like quote on re-insulation options. Looking to replace AC unit which is dying. Want to optimize energy efficiency.
Wolftrap Ct in Vienna
A little history of what is triggering this project. Originally had our annual gutter cleaning, but they were unable to do so thanks to a family of squirrels living in our gutters. This prompted a visit from the pest control whom noticed some gaps between the roof line. He inspected the attic and found evidence of mice whom in addition to leaving their signs of living in the blown insulation, had also matted good portions down by walking through it. All the insulations needs to be replaced and the area dissenfected. Since I have to go through all this effort of removing and replacing the insulation, my thinking is rather than doing more blown insulation, to spray foam and seal the attic space all together. Details of the home: - 3 Story above ground townhome in vienna - Attic has an access hatch with no stairs - Current insulation is a combination of batt insulation near the eaves and blown insulation with a reflective thermal barrier on top - Dimensions of the townhome are approximately 21'x 41' - Large circular gable vent on front of the house Quotes Requested: - Spray foam insulation and air gap sealing - Insulation removal

I have a bathroom fan that, when turned on in the summertime, will drip water from the slats. I think condensation from the A/C vents is accumulating and then dripping down. Is this something your company can look into and fix?

Our house has an addition that I estimate is over 20 years old and it is very drafty. Also, I am concerned about a draft in one corner of our house too. I would appreciate it if someone could come out and look at these 2 situations and give us an estimate. Thanks.
Carpers Farm Ct, in Vienna
We need advice and assistance to address significant comfort issues in one large room in our house. The room is just over 400 sq. ft. It sits over the garage, has exterior exposure on 3 sides and has a high vaulted ceiling (no attic). Consequently, the room is very cold in the winter and hot in the summer. Additionally it sits at the farthest point in the HVAC duct work of the house, so the HVAC system provides little comfort to the room. I would like to understand options for adding significant insulation in the floor, walls and ceiling, as well as learn of any recommendations you might be able to make to improve this room.
