This Round Hill VA home had issues with condensation forming on the HVAC ducts due to temperature variations in the rooms the ducts were passing through.  This issue is known as "Duct Sweating" and can lead to stained or damaged drywall as well as mildew or mold growth.  After calling us to help with their home concerns, our Home Performance Sales Pro Pedro went out to perform a whole home inspection and advised on having the HVAC ducts encapsulated with spray foam.  This service would protect the conditioned air travelling through the ducts and reduce the chance of any future duct sweating.

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 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?

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!

Zyp Foam to the rescue

It may not look like much, but this orangish pink goo could be the key to making your home more comfortable.  From crawl space encapsulation with wall insulation panels to an attic space like the one pictured here, an air seal can be the building block that helps make any project a success.  Zyp Foam is what we used to seal up cracks, gaps holes, and any other type of small space that can allow air to move in or out of a room or area in your home.  Keeping conditioned air that you paid money to heat or cool inside of your home and keeping unconditioned air out of your attic or basement will make your home more comfortable and healthier.  After air sealing an attic space with Zyp Foam, we will often cover the area with Tru Soft blew cellulose insulation to further create the desired type of control.
