This Purcellville homeowner was looking for a great way to insulate the basement and have it prepped to finish before putting it on the market for sale.  They didn't want to finish the basement completely, but wanted it "ready to finish" so the buyer could build it out as the wished.

Comfenergy found the ultimate solution by using Basement to Beautiful wall panels. These wall panels are insulated with SilverGlo foam and have the metal studs already built into them.  Each insulated Basement to Beautiful wall panel is held in place with foam spray insulation, and then secured using long bolts. There are 3 distinct advantages to these wall panels. 1) Once they are installed, the room is ready to be finished because the framing is built in. 2) They provide moisture intrusion control. 3) The Basement to Beautiful panels are infused with anti-microbial materials and will not mold nor mildew.

This Purcellville, VA home was suffering from rooms that were too hot in the summer and too cold in the winter. This was having a serious negative impact on the comfort level of the home. When our sales professional Jason went out to the property to perform a full home inspection, he determined that the best course of action to end their discomfort would be to air seal the attic add new insulation and install a radiant barrier. Jason explained to the homeowners that the primary cause of their discomfort was the insufficient insulation. After the homeowners agreed to Jason's solution our service crews went out to get to work on the home. The crews started by removing the old insulation. Then they Applied ZypFoam air sealant to make sure the attic wouldn't have any air leaks. After that, they installed the new insulation. Finally, the crew installed the radiant barriers to reduce the temperature in the attic.

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

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.

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!

Our garage is finished and 3/4 of it was insulated when it was built circa 2005. We're new owners (2nd owners of the home), and we'd like to insulate the exterior wall that is not insulated.
Project Location: Purcellville, VA
Purchased 1964 home last fall. Rehabbed by seller but not completely. Valor Mold conducted major mold removal for us in unfinished basement. They recommended your company as a follow-up for energy audit and checking duct work. Reason for contacting today: with HVAC running last two weeks we get a bad mold-like smell from basement air intake that vents on main floor. Basement itself smells ok, not too humid and no signs of mold. We wonder if crawlspaces could be source of smell, not sure of condition of ducts in/near those spaces.
