This Reston, VA attic had low-quality insulation that was making the home too hot in the summer and too cold in the winter. We went out to the home and had our sales professional complete a full inspection. He determined that the best solution would be to tear out and dispose of the old insulation, add ZypFoam to air seal the freshly cleared attic floor, and then add new TruSoft cellulose insulation to keep the home comfortable year-round.

This customer in Reston called about rodents in their attic and some issues with uneven temperatures throughout their home. Carl Depner went out to do an inspection and identified several potential services to help with the situation. A removal of all old fiberglass insulation was done along with removing any existing rodents and or waste. The floor of the attic was air sealed to help keep conditioned air inside the living space of the home, MoldX fogging spray was done to help reduce the possibility of mold in the future and the entire attic was covered in TruSoft Cellulose insulation. This will all help to better control the temperature inside of the home and reduce the possibility of rodents returning to the attic.

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!

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?

Job Stories From Reston, VA
Happy homeowner after service.

This client was so happy with the results of her home's service that she reached out to give feedback on the work and team that visited her home.  We thrive on client feedback and do our best to exceed expectations for every project.  

 

I just wanted to let you know that the work that was done in my house made a WORLD of difference!!!  My upstairs bedroom is perfectly comfortable now – the heat comes blasting out of the vent.  The main floor is also more comfortable in the front room (over the storage room that had the exposed floor). Overall, the temperature is very even throughout the home.  I think that duct cleaning and sealing may have been the key to making this change.  While the insulation needed to be done (for sure), the vents upstairs now blow air much more strongly. Also, adding the return register and sound-lining the return ducts cut down on the noise. I don’t even notice the heat when it’s on.  I am waiting to see how things sound with the AC – that was always a lot noisier.

Just wanted you to know!

Thanks for everything,
