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!.

Attic Insulation Services Available in Clifton:

  • Blown-in Insulation
  • Blown Fiberglass Insulation
  • Radiant Barrier
  • Rigid Foam Insulation

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!

Complete Insulation Services You Can Trust!

Comfenergy is Northern VA'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!

House built in 1967. High Oil heat and electrical bills. Cold family room area over crawl space. Heat ducts not insulated. Basement cold. Drafty windows and other draft sources. Insulation and energy efficiency of house needs to be brought up to modern standards.

Hello, my home energy costs are high and temperatures are uneven. I am looking for an assessment to see which improvements provide the best value. Thanks!
Project Location: Clifton, VA
Purchased a fixer upper last year that was built in 1977. The home has original windows but also is drafty in other areas. We would like your home energy audit and to hear what you deem as our priorities. Also, it would be great to hear a plan on how to fix our issues along with an estimate.

Sons bedroom closet very warm, other sons wall seems poorly insulated

I need insulation blown in between the ceiling of my 4- car garage and the finished room above it.
Project Location: Clifton, VA
1. Cold and drafty mudroom (5-10° colder than rest of house) addition added by prior owners. Draft from room chills rest of adjoining areas. Addition (154 sq ft) sits over crawl space. 2. Living room drafty, significant draft from fireplace when not turned on, cannot close flume due to pilot light. Overall goal - even out temperature in house, basement currently warmest area in house, master bedroom/bath coldest. Counterintuitive to us.

Hello, We recently bought a 1900s farmhouse in Clifton that we are fully renovating (in most areas down to the studs). We are interested in getting a quote for air-krete insulation (or other recommended options--I am sensitive to fumes and am looking for alternatives to spray foams). Particularly, the attic roof (new metal roof to be installed) and the crawl space. Possibly the exterior walls that are being opened as well. Thank you! Bonnie (email is the best way to reach me)
