"Thank you Aaron and Bob for another excellent joy with another window project. We are equally thrilled with the workmanship of the installation and the quality of our new window as we were the last time you did a big window job for us. We appreciate your professionalism and dependability."

"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."

"They are extremely experienced with window repair. After months of search for someone to repair the window, everyone wanted to replace it. The called promptly, took the broken sash and returned it the same day for a fraction of what other companies quoted. It was a Marvin double pane window with decorative wooden trim, more involved then a regular window. I was beyond thrilled with their work and results."

"Ashraf was professional and cared about the work he was doing. He would not leave until my screen door was in "just right" after repairing it. He took pride in his work and that is hard to find these days! I would definitely hire him again."
