“I wanted to thank you for you and your team’s hard work during our patio door installation. From ordering the doors and our initial discussion, to final install–it went great. As you know, having nine patio doors replaced is no small project; however your team made it look easy. The install went very smoothly and was completed in one day! This made me and my wife very happy, since we did not have to deal with the mess associated with this type of project for days on end. In fact, when my wife got home and the doors were in, she couldn’t believe the team was done and cleaned up already. I really appreciate working with you and let me know if you ever want me to speak to a prospective client.”
