Injection Foam in Basement Floor Injection Foam in Basement Floor

We had to use injection foam under the floor system of this home in Great Falls Va.  Foam was squirted into the cavities under the subfloor until it appeared by foaming out of a hole on the other side off the room.


Very cool way to fix the problem of cold floors in this house that was under rennovation.

Home Insulation Services You Can Trust!

Comfenergy is Nova'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? Because of this, your home may feel drafty or uncomfortable throughout the year, mostly in the summer and winter, and this can increase your home energy costs. Proper insulation in your home allows your heating or air conditioning systems to work more efficiently which will save you money. 

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!

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 Include:

  • Provides both insulation and air sealing; air sealing is excellent because the foam expands to fill gaps and cracks.
  • High R-value -about R-7 per in. depending on the formulation.
  • Speedy installation. Foaming can be done in a fraction of the time it takes to cut, fit, and seal rigid board insulation.
  • Once cured, spray foam insulation stays in place; it won't shift, settle, or fall out of place.

In 2012, we purchased a home with a finished basement. Unfortunately, this space is very cold in the winter and it is likely that it was not properly insulated prior to installing the drywall. There is an unfinished area with insulation in on the top 1/3rd of the wall. The insulation is fiberglass with a foil covering. Can you help?
