Get matched with top insulation pros in Potomac Falls, VA

"Outstanding work insulating both my basement and attic. If I ever again have the misfortune of needing to insulate anywhere in my home, I will reach out to Prudent Homes. Honest, reliable and technically competent."

"I've been trying to find an expert in insulation for months to come out and tell me out to properly insulate around a removed chimney and Comfenergy was the expert I needed. Even though the insulation part of the job was too small for Comfenergy (wasn't above their minimum quote value) they were happy to give me their expert advice and I appreciate the time spent as I now know what to ask the roofing contractor to do in order to insulate this correctly. Thanks!"

"It was amazing, took all day to get the old insulation out, seal the holes, and refill with new insulation. Would recommend this company to anyone looking for a professional service to improve insulation and save money on heating and cooling costs."

"I am very pleased with how my attic insulation project turned out. when the company came to my house to give an estimate they evaluated my current insulation, told me what I needed to bring my home up to the current standards for attic insulation. (r49) more importantley they told me what I didn't need. I highly recommend this company for your insulation project."

"Founders Insulation did a very good job on installing insulation in ceilings! They were careful, courteous and cleaned up."

"These guys were the benchmark for contracting work. Quick estimates on pricing that they stuck to. Timely quality work, and a great clean-up effort. 10/10 would recommend for insulation work."

"Window & roof insulation quick, easy, & affordable!"

"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."

"The project was to insulate a cantilever kitchen bump out that had sink pipes running under it. Both the sales adviser and the project manager were outstanding. Mike Wilson did a great job explaining everything he was doing as he was doing it, capturing with photos and doing everything the right way! Definitely recommend them and use them again."
