Before and After Pictures from Dumfries
Dumfries VA Duct Spray Foam Duct Insulation

Before After
Dumfries VA Duct Spray Foam Duct Insulation Dumfries VA Duct Spray Foam Duct Insulation

This Dumfries VA home had condensation along the HVAC ducts (duct sweating) due to external heat making its way into the home via uninsulated rim joists on the side of the house.  Hot air from outside was working against the cold air moving through the HVAC ducts and causing the duct sweating which was showing itself as water spots on the basement ceiling drywall and mold.  Our production team encapsulated the duct with spray foam and then administered Aero Seal to the inside of the system to eliminate the opportunity for conditioned air to escape.  This process will stop the duct sweating and keep the conditioned air inside of the HVAC duct from experiencing any external temperature influence.  The air will reach the rooms it is intended to cool or heat and reduce the need for the HVAC system to work as hard as it had been. Improved comfort and reduced energy cost for the homeowner.

This Dumfries VA home was having comfort issues that the homeowner wanted to eliminate. They called us to come and help.  Our Home Performance Sales Pro Carl completed a no cost inspection of the whole home and identified a need for some work to be done in the attic which would help improve the comfort and energy efficiency of the home.  In addition to air sealing and installation of new Tru Soft cellulose insulation, Carl recommended having the HVAC duct sealed with spray foam at different points where joints and exchange boxes were allowing conditioned air to escape.

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!
