"Install crew was perfect. No dust, no mess. Complete cleanup, and a perfect airtight install. For years we have had winter management strategies. Closing off room on the north side... and running space heater in those rooms during use. After installation of the ProEdge windows these rooms are as warm as the rest of the house. AMAZING! Recent warm days prove the advantage of triple glazed low-E windows, too. Nice and cool inside. I searched for years for new windows that met MY specifications . As a career engineer I am happy to recommend ProEdge to anyone. Their attention to detail is superb."

"Dylan did a fabulous job managing our window order, ensuring we had the right measurements and showing us how to use the windows and door. Diego, the crew leader, was polite and worked with us to move everything we needed away from the old windows. We are happy with our new windows! Home genius also installed our new roof and gutters. Each job was completed in one day including cleanup. They were careful to minimize damage to flower beds. Crews were on time, and minimized disturbance. Home Genius has done a good job choosing their contractors and job site managers, clearly focused on customer service and provides quality workmanship."
