Before and After Pictures from Vienna
Vienna VA Home Remodel with Insulation

Vienna VA Home Remodel with Insulation

Vienna VA Home Remodel with Insulation Vienna VA Home Remodel with Insulation

This Vienna VA home was being remodeled and had its interior frame stripped down to allow for installation of more modern insulation products.  Our team started working in the attic before addressing the inside of the walls in the rooms below.  Old insulation was removed and the attic was air sealed with Zyp Foam in order to control unwanted air flow in and out of the space.  A new attic floor decking was constructed by our team along with damning/walls to hold in the Tru Soft Cellulose Insulation that would later be blown in.  A zippered Attic Tent door cover was installed to properly seal up the attic door and control air loss from the rooms below.  The final result for the attic was a thick layer of insulation and a more energy efficient top floor of the home.  The floor/decking would allow for storage space and the ability to walk around the attic.

This Vienna, VA home was suffering from summers that were too hot and winters that were too cold. This was having a serious negative impact on the comfort level of the home. Our sales professional Greg went out to the property to perform a full home inspection and find the best possible solution to the homeowner’s discomfort. After completing the inspection Greg explained to the homeowners that the primary cause of their discomfort was a poorly insulated attic that was completely lacking in any kind of proper air sealing. He determined that the best course of action to end their discomfort would be to air seal the attic to stop any air leaks and to install new high-end insulation. After the homeowners agreed to Greg's solution our service crews went out to get to work on the home. The crews started by removing all of the old ineffective insulation that was failing to protect the home. After that, they apply ZypFoam air sealant to plug all the potential leaks in the attic to prevent uncontrolled unconditioned air from flowing freely into the home's living spaces. Finally, the crew installed the new TruSoft cellulose insulation to keep the home comfortable year-round.

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?

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!

Hello, we found water dripping from the ceiling of our daughter's bedroom last week. Our HVAC & plumbing company investigated & discovered condensation dripping from uninsulated air ducts. (We had a new & much more efficient HVAC unit installed in May 2022.) The techs suggested we contact someone who can spray insulation in the area where the condensation is pooling. Attaching pictures below. Hoping you guys can help us! We also have a couple of other areas in the house that we suspect are not insulated at all we would like you to inspect if possible. Thank you!
