    Customer Testimonial

              Hi Mike – Just wanted to send a quick note to say thank you again for everything. We really appreciate the initial work and returning to fix the guest room. It has made a TREMENDOUS difference from where we started in September. Our upstairs remains at a consistent, comfortable temperature, and the kids are sleeping beautifully. And we’re confident our energy bill is (or will be) lower as well. We will definitely recommend you and Comfenergy to friends and family. Thanks again and Happy New Year! Best, Mike

    Greg B. of Centreville, VA

    Customer Testimonial

              Corey, I wanted to send a quick note to say thanks. Our crawlspace encapsulation and fireplace bump out insulation work was completed last Friday. The crew led by Ismael did a really good job...the crawlspace looks great and I already have things stored in there. I put down some interlocking rubber/foam flooring (from Costco) over top of the CleanSpace liner to protect it when sliding plastic containers, works great in case you want to recommend to anyone who plans to use the crawlspace for storage. We already notice a huge difference in our family room above the crawlspace, between the encapsulation and the fireplace insulation it's much warmer in that room, especially in the evenings. No air draft around the fireplace insert. All in all a great overall experience, from my initial call, to your comprehensive energy audit and estimate, to the scheduling and the work being done. Thanks for answering all my questions in emails and texts along the way. Sincerely, Gregg B.

    Spray Foam Garage Ceiling-Ashburn, VA

    This Ashburn, VA had rooms over the garage that were too hot in the summer.  This is can often be caused by fiberglass batts installed by the builder in the ceiling of the garage.  They fall away from the sub-flooring depleting all thermal insulating value.  This customer decided to remove the entire garage ceiling and use closed cell spray foam to fix the problem.

  • Garage Insulation in Sterling VA
    Before

    Garage Insulation in Sterling VA

    Cold floors in rooms above garages are typically caused by air gaps between the sub-flooring above and the fiberglass batt insulation below. Any time insulation does NOT touch the surface you are trying to keep warm or cool...it will NOT work!

    See how big the gap between the floor and the insulation is in this Sterling Virginian Home WOW!!!!  This might have been the worst we have ever seen...Might be 2-3 feet of a gap!

    Our team spray foamed the gaps to ensure no air leakage. These floors are now much more comfortable!

    Venting Bathroom Exhaust Fans in Sterling, VA

    Once we created an attic access in this homeowner's home, we found two bathroom attic fans that were exhausting into the attic. In the wintertime, this hot humid air, blowing into a cold attic will create condensation and possibly mold on organic material. We took action and vented them outside of the house through the gable.

    Decreased cold drafts for homeowner in Herndon, VA

    This home in Herndon, VA was experiencing cold drafts this winter and found it expensive to keep their home warm.  In the attic there was very little insulation and had a low R value.  We used our TruSoft Blown-in Insulation resulting in a less drafty and more comfortable home.

    This wise homeowner in Herndon, VA chose to use closed cell spray foam insulation in the walls of their new home. This is a wise investment for comfort and efficiency.  Closed cell spray foam not only insulates better than fiberglass batts, it creates a great vapor barrier on the exterior walls.

    High Humidity Issues-The Plains, VA

    The homeonwer living in The Plains, VA was having trouble reducing the humidity in their home all year round. During the comfort and energy evaluation it was found that the humidity source was the dirt floor crawl space allowing the humidity from the Earth to rise through the house.

    Comfenergy installed dimple matting, Terra Block floor insulation, CleanSpace 20 mil vapor barrier, and then closed cell spray foam insulation. Now the humidity can be controlled as it is not allowed to enter the home.

    This Broad Run, VA homeowner was suffering from cold floors and kitchen cabinets. Upon a full comfort evalution by Carl Depner, he found there to be cold air coming through the back of the home.  This cold air would travle beneath the floors above and even into the kitchen cabinets.

    Closed cell spray foam was used to perfect the air and thermal boundary to make the floors and kitchen cabinets warm again!

    Loss of Energy- Ranson, WV

    One of the biggest culprits of heat loss in the winter (and high energy bills) is recessed can lights that back to the attic.  The attic is outside the home and the top floor in inside the home.  These can lights are 6" holes in the ceiling that allow heated air out of the home. Covering them and sealing them keeps the heated air in longer and lower the usage of the heating system.

    This MArshall, VA homeonwer had no insulation, causing the basement to be cold in the Winter. Comfenergy installed 2" thick Thermax rigid foam board panels and now the basement is warm and comfortable.

  • Cold Basement-Flint Hill, VA
    Before
    Cold Basement-Flint Hill, VA
    After

    Cold Basement-Flint Hill, VA

    This Flint Hill, VA homeowner always had a cold basement, specifically their laundry area.  Presently, it was insulated with loose fiberglass batts pinned to the wall. This neither stops air from traveling into the home, nor provides much of a thermal barrier. The rim joists at the top of the wall were also merely insulated with fiberglass batts.

    Comfenergy put together a solution that was effective, and appealing to the eye!  The fiberglass was removed and disposed of. Thermax (polyisocyanurate) boards were attached to the walls, with foam and tape sealing the gaps. Then, the rim joists were sprayed with closed cell spray foam to air seal and insulate them too.

    Now the homeowner can perform laundry duties no matter what time of year it is!!!

    Vertical walls with little/no, or fiberglass insulation on them allow the 130 degree attic heat to radiate through the drywall into a bedroom. SilverGlo foam boards (4" thick) can fix this problem.

    Cold Rooms-Rixeyville, VA

    This Rixeyville, VA homeowner was complaining about a cold room on the upper level of their home. After a full comfort evaluation provided for FREE by Comfenergy we found an attic that was adjacent to this room. The wall adjacent to this attic was merely insulated with fiberglass batts.  The problem with this is that fiberglass does NOT stop air from travelling around and through it.  This is why your furnace filter is made of fiberglass. It allows the air through, but not the dust and dirt.

    Comfenergy solved this issue by using 2" thick EPS SilverGlo foam boards to secure on this wall to provide a good air barrier and an additional R10 thermal insulation value.

    Now this room is toasty warm and can be used in cold winter months!!!

    Leaky & Poorly Insulated Attic Duct Work in Boston, VA

    This Boston, VA homeowner had issues staying warm in the winter and cool in the summer. A FREE comfort evaluation by Comfenergy revealed, among other things, an HVAC ducting system located in the attic that was both leaky and not insulated.  The hot air was leaking into the attic in the winter. The cold air was becoming re-heated in the summer. Not only was this causing discomfort, but it was making their utility bills go literally through the roof!!

    Comfenergy encapsulated the attic ducting system to seal it from those air leaks. This keeps all of their air in the home!  It also insulates the air travelling through the ducting system so that it comes out of the vents at the right temperature to stay comfortable.

    Attic Insulation in Mclean, Va

    This customer in Mclean, VA called us as they wanted to add more insulation in the attic.  We did air sealing to stop the air leakage, as well as built plywood dams to keep the insulation in place and off the newly built storage deck.  New decking was installed for storage and air sealed at the seams.  Insulation was upgraded to R60. The result of doing this is better insulation & air sealing keeping the house warmer in the winter and cooler in the summer.
