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.

W Meredith Dr in Vienna
Our house has an addition that I estimate is over 20 years old and it is very drafty. Also, I am concerned about a draft in one corner of our house too. I would appreciate it if someone could come out and look at these 2 situations and give us an estimate. Thanks.
Carpers Farm Ct, in Vienna
We need advice and assistance to address significant comfort issues in one large room in our house. The room is just over 400 sq. ft. It sits over the garage, has exterior exposure on 3 sides and has a high vaulted ceiling (no attic). Consequently, the room is very cold in the winter and hot in the summer. Additionally it sits at the farthest point in the HVAC duct work of the house, so the HVAC system provides little comfort to the room. I would like to understand options for adding significant insulation in the floor, walls and ceiling, as well as learn of any recommendations you might be able to make to improve this room.

Our house has a particular room/area on the first floor and another on the second floor that get quite cold in winter. Seeking solutions that won't involve entire house or very high costs.
Batten Hollow Road in Vienna
I have a large unfinished space in my basement that has insulation issues and infiltration issues where mice have been entering. I believe it's at the rim joist area where there is currently some fiberglass batts stuffed in there that are inadequate and possibly hiding some penetrations to the outside that would need to be sealed up first. So, remove old insulation, inspect, seal up all penetrations then new insulation installed.
