This Woodbridge VA home had a top floor that was too hot.  During the Home Performance Inspection, our sales pro Pedro discovered an improperly design bathroom exhaust vent.  The vent extended just into the attic and was distributing air from the bathroom into the attic adding unnecessary moisture to the space.  Our team extended the vent and made it properly exhaust air outside of the home.

Any proper attic insulation project should include air sealing.  Often times we find clients who previously worked with other companies and the only thing they did was add insulation on top of what was originally there.  We make sure to take the extra time and remove existing insulation so that we can use Zyp Foam to seal up all of the gaps, cracks and seams in the attic floor.  This helps prevent conditioned air loss from the rooms below, making homes more comfortable and energy efficient.  After air sealing, we blow in new Tru Soft cellulose insulation.

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!

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!
