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!

The previous owner had blown-in insulation and built a storage space in the attic. We would like to get our attic space insulated correctly to increase the energy efficiency for the living area. Our colleague Josh highly recommended your company.

We are currently having a screened in deck built in which they ripped out the old outside wood and inserted some beams in our crawl space area. We could see light coming in from the outside. We would like to get an estimate on spray insulation/regular insulation in just our basement and crawl space area so bugs cannot enter easily and also to weather proof.

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.
