"I am very skeptical of roofing companies, or just contractors in general. I read a lot of reviews, but rarely take the time to make a review myself. I had such a great experience with Star window doors roofing etc.. that I decided to write this review. My salesman, Dennis was top notch. He was very knowledgeable, responsive, and kind, never pushy."

"Steve and Alex did a wonderful job installing 2 of my shower doors. They were extremely professional. I would definitely recommend AMG Group. They also did a fair pricing and were able to do a competitor price match."

"Alex responded quickly to help me get six very old third story dilapidated attic windows replaced. He and his coworker came, measured and special ordered new windows at a fair price. They did excellent and efficient work in a difficult to work area. If you need windows replaced or repaired Wet Seal is who I would recommend. I appreciate all he did and the windows look great. Thank you Alex"

"A wonderful experience all around! We had 15 windows and a sliding glass door replaced. Our Salesperson, Harlan, was very professional and explained the benefits of the new windows and all about Power as a company. The installers arrived on time and completed the entire job in a day! Everything was installed perfectly and the crew was courteous and cleaned up after themselves. Erin came to visit the next day to make sure everything was up to their standards and addressed any questions we had. Most certainly the best experience we've ever had with a home contractor. Highly Recommend!"
