"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"Highly recommend. Exceptional and professional service from their contractors and most especially by Nolan Walker (Performance Consultant). Nolan showed photos taken of my home's ductwork and insulation and provided a list of options and the cost of each project so that I could make a well informed choice of which projects to pursue. He took his time and was honest and understanding - not aggressive like other companies I have dealt with. His test-out and follow-up appointment was just as thorough. It was a pleasure working with him."

"We needed insulation applied only to the underside of the house at this time. The guy who came out to give an estimate was great. The guy that came out to do the spray job (I expected a team and got just one guy) was super nice. The spray foam would appear to be difficult to manage during application as some spots only have a skim of insulation while others seem to have 7 inches of it. The office..... trying to get any information from that office.... was a hassle way beyond my wildest nightmares. Getting the estimate took days, getting scheduled took days. They have only one person working to do all of the scheduling and she "is out of the office" during a whole heck of a lot of "our office hours are from...". Figuring out what I needed to know to pay online took pulling teeth. It was the best price I got and it will make a world of difference to that house structure and its moisture issues.... but good grief!"
