This Fairfax VA attic wall didn't stand a chance against outside temperatures without any insulation.  Spray foam was used to fill in between the framing to create a better air seal and insulate the attic space from the outside temperatures on the other side of the wall.

In addition to air sealing and insulation an attic, it can often be helpful to create a better landing area for someone to stand on when entering the space.  Creating a platform such as this one will help to keep insulation from falling into the hallway below and allows for a way to safely stand in the attic to look around or start to access any utilities or storage space.

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!

Job Stories From Fairfax, VA
Radiant Barrier for Comfort and Storage

A radiant barrier should always be a part of a home's insulation system. It functions to reduce temperatures in the attic by reflecting heat away. Radiant barriers are installed around the joists, roof beams, and wall studs - when combined with other insulation services, your attic can become a conditioned space. 

Besides comfort, installing a radiant barrier can allow you to use your attic for storage, because the heat will no longer damage your belongings. Radiant barriers can lower attic temperatures by up to 30 degrees. An insulated attic will also keep humidity lower, preventing moisture or mold damage to your things as well.

Hello! Looking to get the insulation in our entire home replaced with foam, and possibly a bay window replaced. Current insulation is most likely old and sunken to the ground. Elevated moisture levels were found in multiple areas of drywall throughout the home (mostly around windows)(some mold remediation will be completed in the coming weeks. Other water intrusion issues aside, looking to control humidity levels as well. Thank you!

Interested in getting a estimate for Attic insulation (Finished 1535 sq. ft. ) home with a two car garage sq. ft.?
Project Location: Fairfax, VA
Wondering about quotes on lowering the temperature in our 3rd level living area of our townhome (built 1968). We are curious about close foamed sealant costs and an assessment of what else would be most effective to bring the temperature in our top floor down to a reasonable level in the hot summer months. Requesting a quote for insulation in the attic (close foam, and blown in separately) as well as any other ideas that may help with our issue. Thanks, Jeff

Attic Insulation
Project Location: Fairfax, VA
My attic is so hot during the summer and the AC is running all day but the room is still too hot.
Project Location: Fairfax, VA
During our home inspection it was noted that there is an insufficient amount of insulation in our attic space, we would like to get a quote for how much it would cost to increase our insulation to the appropriate amount - I believe we currently have blown insulation in the two spaces.
