    I can not say enough good things about the way the owners handled a situation that came up during an installation. They were both on top of it and made us very happy customers. THANK YOU!!! Things happen and the way they handled this was fantastic.

    By Gary S.
    Reston, VA

    The professional engineering assessment by John at our house helped us decide to choose a more expensive method to insulate our attic - and we noticed the difference the day the crew left - we were hot when usually on a cold day like that we would be cold outside. Outstanding assessments, work, customer service, and follow up. We will use you again in the very near future.

    Customer Testimonial

              I thoroughly reviewed your web site, looked at the various videos and understood what Dr. Energy Saver could do for me. Having obtained additional estimates, I was surprised at the variance in price for the same services. Mike indicated that Dr. Energy Saver would match comparable prices for the same services plus an additional $100.00

    Customer Testimonial

              Thank you for the outstanding job done by the Comfenergy team on insulating my basement on November 14, 2016. My sales rep, Shayne Sandner, was friendly and very professional. He answered all of my questions and inspired great confidence. His emphasis on quality and standing behind your work helped me to select Comfenergy as my spray foam vendor. His pricing was very close to the quote I received from one of your competitors. Communications from Comfenergy were clear and kept me informed of the planning and scheduling process. Your team did the work while I was away on vacation, with my father letting them into the house and checking in after the job was done. When I returned home, I found that you were generous with your insulation - you fulfilled (actually exceeded, for the most part) your 2" insulation thickness commitment throughout the basement. I was also happy to find that there was zero residual odor (your team installed on a Monday and I returned home the following Sunday). Your team paid attention to the details, such as installing rigid insulation around window and door rough-ins to ensure uninterrupted insulation and to prevent any foam from interfering with my future trim installation. The Comfenergy team did a fantastic job of cleaning up. Not a spec of foam on the floors or anywhere else that it wasn't supposed to be. Even more evidence of your customer focus is that your team did not push me at all to pay for the work prior to my return home from vacation, so I could inspect the job. Nicely done Comfenergy! Thanks for your exceptional performance and customer support.

  • Frozen Pipes in Ashburn, VA

    Frozen Pipes in Ashburn, VA

     The homeowner in Ashburn called,  as last year their pipes froze and they did not want that to happy again.This home i has always had issues with hot and cold spots, and freezing pipes in the winter.  We found cold air in the master bedroom attic to be getting around the batt insulation leading to the bathroom above.  This entire neighborhood of as notorious drafts and hot/cold spots. These homes have also dealt with many frozen water lines. The water lines were freezing almost 20 feet from the exterior of the home! Comfenergy installed 4" thick SilverGlo foam boards with heat reflective barrier on the attic walls.  

    Problem solved!!!  Foam board insulation in an attic keeps the cold air from travelling beneath the bathroom tub and the pipes from freezing.

    The homeowner will be more comfortable in the Summer and Winter.....but it lessened the draftiness of the home, and the pipes don't freeze any more!!!

    Basement Insulation in Purcellville, VA

    This Purcellville homeowner was looking for a great way to insulate the basement and have it prepped to finish before putting it on the market for sale.  They didn't want to finish the basement completely, but wanted it "ready to finish" so the buyer could build it out as the wished.

    Comfenergy found the ultimate solution by using Basement to Beautiful wall panels. These wall panels are insulated with SilverGlo foam and have the metal studs already built into them.  Each insulated Basement to Beautiful wall panel is held in place with foam spray insulation, and then secured using long bolts. There are 3 distinct advantages to these wall panels. 1) Once they are installed, the room is ready to be finished because the framing is built in. 2) They provide moisture intrusion control. 3) The Basement to Beautiful panels are infused with anti-microbial materials and will not mold nor mildew.
