"Prompt, courageous and provided exactly what I needed. There was little to no insulation nor room in the attic. I priced it out and started to wonder ‘..can I really do this job myself?’ Maybe 10 years ago but the price for Pink blown- in insulation was so good- I couldn’t afford not to have Home Genius Exteriors do the job. I am so happy to see that beautiful sea of pink insulation. Kudos"

They explained their processes start to finish, answering all questions along the way. Even in the face of obstacles due to the nature of my unique attic, they overcame and completed the project on-time and to complete satisfaction, absolutely astounding job! A giant thank you to the crew; Brad, TJ, JB, Jeremy, Anthony, and Jason!"

"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!"
