They're a veteran owned business, and they took very good care of us. Spotted a lot of issues in our attic from previous contractors and remediated them. Since the installation and seal, our AC is effortlessly keeping our home cooled through this historically hot summer. We've had a lot of contractors over the years and have often been disappointed by the quality of their work. John was extremely professional in diagnosing our issue, coming up with reasonable, affordable options, and executing an immaculate insulation removal and replacement. You will be glad you chose this business.

After 40 years, our insulation was falling off. We also had (they discovered) squirrel damage…read more C.I. had a team of extremely hard-working folks who removed all the old stuff, repaired the squirrel damage, and then sprayed foam throughout our attic. The work was noisy and their workday was long. But worth it. The price was not inexpensive, but we believe for the number of workers, and the extent of the work, the price was fair. It's not something I want to be good at.

After getting several quotes, I chose Founders insulation to remove my old fiberglass insulation…read moreand replace it with cellulose. I would give them five stars for their prompt communication setting up the initial appointment, for providing a competitive quote and then answering all my questions about the insulation product they were going to use. I felt my concerns were heard and responded to respectfully, especially by the owner Brian. The crew that did the removal and installation were also punctual, friendly and took good care of my property. Despite working long hours in 100 plus degree conditions. The only reason I dropped a star was because after the dust settled and we were able to access the attic we noted a few things that bothered us. Most of these issues could have been easily addressed if the installation crew had been more communicative with us throughout the process. Instead we had to deal with these issues afterwards which was rather frustrating and took several weeks to resolve and required us to call in other contractors. I would still recommend this company for all the things that they did well. But more and better communication from the work crew would have made this an overall five star experience.

HIGHLY RECOMMENDED! GREAT WORK AND STELLAR CUSTOMER SERVICE!…read moreI had an excellent experience with Founders Insulation and owner Brian Handy. Brian's a great guy--knowledgeable, honest, responsive, and easy to work with. He clearly explained what was needed, what was optional, and why. He showed exactly where the insulation and air-sealing problems were, giving me complete confidence in his recommendations. There was no pressure to add unnecessary work, and everything stayed within budget. Work included removing old attic insulation, extensive air sealing, insulating the attic to R-60, sealing the attic hatch, adding insulation to vaulted ceilings, and spray-foaming problem areas and a cantilever. The team did an incredible job. I was especially impressed with how thoroughly they cleaned up afterward. Most importantly, I've noticed a significant decrease in my heating and A/C costs since the work was completed. Excellent communication, quality work, fair pricing, and no surprises.

I purchased a 1950's home in Alexandria, VA in 2018; one of the first steps that needed to be…read moreundertaken was air sealing and re-insulating the attic and encapsulating the crawlspace to bring the home to modern comfort and health standards. I went with Comfenergy due to their professionalism and expertise. From the energy audit and consultation (Matt), to the removal and re-installation of attic insulation, crawlspace encapsulation and dehumidifier installation (Dylan & crew), things have performed as expected over a year later. No more humidity, no more overworked HVAC, and no more mud pit under the house. I am writing this review because I had an issue with the dehumidifier that was installed (throwing an error code). I called on a Monday before a holiday and explained the situation. Comfenergy had someone (Ariel) out by Friday to diagnose. He fixed the issue, offered amazing advice, answered all of my questions, and even performed an inspection of their previous work (going as far to spot repair a few places that had weakened due to settling). This kind of customer service, over one year after performing their work, made me feel a whole lot better over such a major investment and project for my home. I believe this is one of those instances where "you get what you pay for," and Comfenergy certainly exceeded my expectations.

Kelvin Insulation (703.675.5499)/Arqueta's True R-Value just finished re-insulating our attic…read more Great job, and a reasonable price. We are pleased. After researching insulation techniques, we decided that the concept of True-R value was the way to go. The True-R value concept is that you need to seal the ceiling/Attic first to gain the True-R value of the insulation you are putting in. Kelvin Insulation, 1) Removed the items we had stored in the attic, 2) Removed the old platform (~600 square feet) used to store the items. They also removed the old attic walkway we built for ease of access, 3) Removed all the old insulation, 4) Sealed the various connection points (to include heating vents, vents, framing connections, etc.), 5) Installed fireproof covers on all the recessed lights, 6) Insulated the attic to an R-49 level with a rigid, batts and blowed-in insulation mix. 7) Built a new storage platform of the same size as the old one and built a new walkway across the attic. 8) Put all our stuff back (more like 1/2 since we use this process to clean out the stored items). Kelvin, the owner, is a knowledgeable, straightforward guy who works with you to get the job done at a very reasonable price. The job took two long days, and they cleaned up after each day. We are pleased with the work and the price! If you need insulation, give Kelvin (703.675.5499) a cal
