"American Home Renewal recently replaced 7 double hung windows in our home. We had 3 window replacement companies come to our home discuss the process and give us estimates. Chris from American Home Renewal was by far the most professional. He spent time with us, accurately described the entire installation process with us and exhibited willingness and patience to hear and understand what we were looking for in the new windows. The American Home Renewal contract was clear, concise and straight forward. The 3 day installation process was fluid and fairly quiet and we were able to work from home. It had a minimal impact on our lives. The crew cleaned up thoroughly every day and took time to make sure we knew how to tilt the windows for eventual cleaning etc. Keith, the Production Manager, checked in a few times during the 3 day installation period to ensure everything was progressing to our satisfaction. We could not be more pleased with American Home Renewal's level of professional service and care."

"Great experience. Found AMG doors and windows online and they reached out and were able to clearly and professionally explain the step by step process of measuring the door ordering and the installation process. They were hassle free and was able to give me and over the phone quote for my new French doors. The install only took them 4 hours and they keep the space clean and were very professional."

"Excellent! They did such a great job and at an outstanding price. I have so many windows in my house and they came in way below any other competitor. It's been a few years but the windows still look and work great! As a matter of fact, my next door neighbor recently hired them to replace all of their windows based on the job they did at my house."
