Home Insulation Services You Can Trust!

Comfenergy is Northern VA'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!

Work Requests From Fairfax, VA
Vicinity of West Constable Court in Fairfax
We have about 1200 sq ft of total attic space, half is cathedral ceiling and half is traditional attic space. Looking at sealing/ insulating the traditional side about 600 sq ft. It currently has only about 4 inches of blown in insulation. Our house temp fluctuates greatly during day to night. Down the road we'd like to insulate the cathedral ceiling and would like recommendations for both.

Vicinity of Swinton Drive in Fairfax
We would like to have a price quote for attic insulation for our home.
Vicinity of Pumphrey Drive in Fairfax
House built in 1978. As is typical for multi story houses, our upstairs is warmer that the down. However, the temperature difference can be over 15° at times. Our A/c unit is only two years old. We believe that attic has never had the insulation redone or it had never been properly sealed. This seems to be a common problem on our neighborhood. We would like to see if there is anything we can do from the attic to mitigate the temperature variance some.

Vicinity of Pine Park Ct in Fairfax
We are purchasing a home built in the mid-1980's. Current attic insulation is inadequate for Virginia climate (roughly 7" loose fiberglass, unevenly distributed). The home also has an attached large modular sun room that was built onto the deck--we are curious to see if the floor of that space is insulated at all and are considering our options if it isn't.
