"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."

"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"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!"

"Stephen and his team did a fabulous job of insulating a space behind a bedroom wall and adjacent bathroom wall that was completely uninsulated. We suffered through two cold winters that heaters couldn't solve in these rooms. Stephen evaluated the project efficiently and then oversaw the work. It was performed beautifully by the team and they cleaned up before leaving. Everything was immaculate. Most impressed with this company and this project manager."
