A homeowner in Gainesville, VA had a broken basement window. Until recently, the standards for basement windows haven’t been very high. Builders paid attention to windows in the main part of the house, but typically chose cheap steel or wood-framed windows for the basement. As a result, standard basement windows have some significant problems. 

The Comfenergy team quickly replaced this window with an EverLast Window Insert. The EverLast Window Insert features double-pane, insulated glass, so you won't need to worry about major heat loss. Our installation crew will use the right techniques to eliminate air leaks through gaps around the window.

A homeowner in Gainesville, VA had an upper floor that was always uncomfortable, especially in the summer. The AC ran constantly but it never felt cool enough in the rooms upstairs. Comfenergy removed the old inefficient attic insulation, air sealed, and blew in cellulose insulation, covering the ductwork in the attic as well. Now the top floor of this Gainesville house is much more comfortable and more energy efficient too.

This Gainesville VA home was too loud for the homeowners liking.   Neighbors with loud tv's and music were unfortunately adding to the noise level.   They called Comfenergy to come try and help.  Our Home Performance Sales Pro Jason went out to visit and did a whole home inspection to look for solutions.  Jason was able to determine that the internal walls of the home had little to no insulation inside and were therefore allowing sound to pass through.   Our production team went out and performed our Dense Packing service.  They cut holes in the dry wall and packed the space inside with insulation that would help control and work to reduce the sound that was bothering the homeowners. The end result would be a quieter room.

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 Gainesville:

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

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!
