Garage Insulation in Sterling VA

Garage Insulation in Sterling VA Garage Insulation in Sterling VA

Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or cool...it will NOT work!

See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!!  This might have been the worst we have ever seen...Might be 2-3 feet of a gap!

Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable!

This Sterling, VA homeowner had a utility room that backed up to their garage.  There was a lot of air leakage allowing cold air to travel through the utility room and into the basement making it cold in the winter. 

Thermax foam boards and one part foam was used to seal this air leakage off, and to keep it safe from flammability.  Thermax is a fire resistant material.

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 Sterling:

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

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!
