"David Sampson of Prudent Homes did an amazing job, I could immediately tell the difference in temperature in the garage and our two pantries where Dave applied blown-in insulation directly above. He made sure to protect all soffits and recessed light fixtures. He also applied insulation around the attic opening and cover. The price Dave charged was well less than a competitor, and Dave was much more thorough in his initial assessment. Dave and his worker made sure to clean up where needed. I highly recommend Dave and Prudent Homes, and will definitely use them again for future insulation needs."

"DMV Insulations is a great company to work with. The company focuses on your personal needs, always on time, and great customer service! Mark was able to answer any questions I had, and provided me with useful information. I would recommend this company to anyone with attic insulation needs."

"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"Home Genius Exterior just completed phenomenal work at my property!! Windows and insulation done. â … Top notch service from the consultation, to the schedule work, the start of the tear down, the installing and the final clean up. Highly recommend this company for your home service. Thank you for the hard work and service!"

"The company did a good job replacing old insulation in our attic. There was a communication hick-up but the project manager we worked with - Jamie - was able to correct and resolve the issue."

"Superb from start to finish! Installed baffles and an additional 10"+ of blown insulation in our attic. Crew arrived on time, protected all the areas, and did a superb cleanup afterwards. The two crew members were outstanding...and very professional at all times. I would recommend them to anyone! Bob C in Burke, VA"

"Jeff and his crew were great to work with. They re-insulated my attic and did an excellent job at a fair price. I highly recommend them and would happily hire them again for other work on my home. 10 out of 10."

"From the start of the estimate with Jon to the insulation project with the Team Leader Carlos, the project went well as expected. Jon was very professional and knowledgeable. He did not try to up-sale services I did not need, and I appreciate his honesty. Jon went over the appropriate insulation for the attic and the garage ceiling to bring our home to a comfortable level. Carlos and his crew did a great job communicating with me while performing the insulation. Carlos immediately notified me of a leak he discovered from the attic fan and temporarily paused the work on the attic and moved to the garage ceiling insulation while I addressed the leak. As a customer, the only comments/suggestions I would give to the crew is: (1) make sure they keep their tools and materials off the lawn (2) make sure the plastic wraps from the materials they use and trash does not get blown away to the neighbor's yard/driveway, and finally, (3) ask the homeowner which bathroom the crew can use while on-site. Overall, I am very happy with Comfenergy and their service. In fact, I have already recommended them to a curious neighbor."
