Vienna, VA Attic Transformation

Vienna, VA Attic Transformation Vienna, VA Attic Transformation

This Vienna, VA home was suffering from summers that were too hot and winters that were too cold. This was having a serious negative impact on the comfort level of the home. Our sales professional Greg went out to the property to perform a full home inspection and find the best possible solution to the homeowner’s discomfort. After completing the inspection Greg explained to the homeowners that the primary cause of their discomfort was a poorly insulated attic that was completely lacking in any kind of proper air sealing. He determined that the best course of action to end their discomfort would be to air seal the attic to stop any air leaks and to install new high-end insulation. After the homeowners agreed to Greg's solution our service crews went out to get to work on the home. The crews started by removing all of the old ineffective insulation that was failing to protect the home. After that, they apply ZypFoam air sealant to plug all the potential leaks in the attic to prevent uncontrolled unconditioned air from flowing freely into the home's living spaces. Finally, the crew installed the new TruSoft cellulose insulation to keep the home comfortable year-round.

Part of this attic project in Vienna VA included wrap insulating this Chimney pipe with a rock wool sleeve. This helps keep the heat being exhausted through the chimney from getting into the attic and reduces the potential for fire hazard.  The existing insulation was removed before the attic was air sealed.  The chimney was then wrapped before new insulation was later blown into 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!

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!

Hi - we live in an end unit townhome. Some areas that are noticeably less insulated: above the garage ( which is the living room floor), gas fireplace bumped out chase. Overall the house has been more builder grade so I imagine insulation is not great across the board. Looking to see what it would cost to have these two areas insulated, and what having the 'whole house' insulated would be.

Our first floor bathroom developed a water stair on the vertical wall. We thought it may be a plumbing issue, but upon cutting the dry wall, found out it was a condensation on the duct issue and was seeping through the dry wall. Our HVAC company, Air Treatment Company, referred you. I'd be interested in understanding how/if you can fix the issue. Ultimately, trying to decide if it's worth a proper fix or if I should try and self-remedy it with some simple bubble insulation around the duct that I can see. Thanks, Greg
