This Great Falls, VA homeonwer was actually a repeat customer.  They were so impressed with what spray foam insulation had done in other areas of their home, that they asked for more now in other areas.

This attic got all new insulation and air sealing done.  We also rearranged the HVAC ducts that were previously laying all over the attic floor so that they are now under the insulation.    Here is the attic hatch area before and after the work was completed.

This Great Falls VA home had rooms that were not comfortable all year round so the homeowners called us to see if we could help.  The attic of the home had insufficient insulation with not enough existing in use and poor quality material.  Our production team removed the old insulation, used Zyp Foam to air seal up the small cracks and gaps in the attic floor and then blew in Tru Soft cellulose insulation.  We added volume compared to the previous insulation and made sure to cover the HVAC ducts as much as possible to help keep them even more insulated than they had been.

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:

  • Provides both insulation and air sealing
  • Fills gaps and cracks
  • High R-value
  • Speedy installation
  • Spray foam won't shift, settle, or fall out of place

Help Your Home with Attic Insulation

Upgrading your home’s attic insulation is a very effective & popular energy-saving method because there is usually a lot of room for improvement. Most homeowners believe their attic has enough insulation but once we explain how much insulation is actually needed to make your home efficient people understand that they don’t have anywhere near enough. It is common knowledge that hot air rises which is why a properly insulation attic is one of the most important things you can do for your home. By adding attic insulation to your home you are guaranteeing to save money and also have a more comfortable home. Not having a properly insulated attic is equivalent to constantly leaving one of your windows open. Don’t wait any longer to learn more about the attic insulation methods we have available in your area!.

Crawl Space Insulation Experts

Do you need crawl space insulation installed or replaced? If so, you're in the right place! A damp crawl space with falling or sagging insulation usually means the space has a moisture problem. If that is the case our team of experts can provide a vapor barrier to keep moisture out of your crawl space. We can then replace your existing insulation with a better option such as rigid foam or spray foam insulation. If your crawl space is completely missing insulation then your home is most likely cold and drafty. This is because the environment in your crawl space will transfer to other parts of your home, which is why proper crawl space insulation is essential to keeping your home comfortable and your energy bills low. To learn more about crawl space insulation cost, call, or click today!

Complete 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!

My pest company came and did an inspection of my attic and showed me pictures of a lot of pest activity, mice, wasps, ladybugs, silverfish, etc. They recommended removing all of the insulation, treating the surface with a bleach-like sterilizer and blowing cellulose insulation on top to reduce the humidity which is causing the wasps and such and cut off the food source for the mice. I'd like an estimate this week and for the work to be done before the end of the calendar year.

Insulating the attic

I know I have a number of issues in our house that need attention, so I'd like to get a comprehensive analysis of all issues and prioritization based on the impacts of each issue so I can figure out what to tackle first.
Project Location: Great Falls, VA
Greetings! I hope as is well. I was wondering is someone could assist with this: The attic is lacking installation and the installation has been displaced leaving large voids. The deck is also showing signs of weathering or deterioration to the sealant. Is there anyway someone could come out and inspect the insulation?
Project Location: Great Falls, VA
We just moved in to a new house and we are seeing a serious temperature difference between basement, first floor and second floor (bedrooms). The house has a single cooling/heating system (heatpump, all electric), and hence a single thermostat. I'm pretty sure the attic is insufficiently isolated. We want to get some independent advice on how to address this temperature imbalance so we know what things to invest in.

Hi! Repeat customer here! We had Climatic at our house this morning looking at some HVAC issues. It looks like we need some insulation added to our attic and possibly having our duct work insulated (it's condensating and leaking on our basement floor). THanks! Keri
