Featured Testimonial

“I am pleased to write this testimonial based on our mutual history and success. USA Architects has had the opportunity to work with many contractors over the years and D&E Window and Door ranks among the finest. Greg and his team execute the project seamlessly, whether buildings are fully occupied or vacant. The entire experience has been rewarding and positive. D&E has a very solid understanding of their craft, client’s needs, project budget, and project schedule. Their coordination efforts with other sub contractor on our projects have been exemplary. USA Architects looks forward to working with D&E Window and Door on future projects.”

“I want to thank you for the professional manner in which you handled our recent window installation project. Even though it was a fairly large project, there were only two small differences of opinion in the interpretation of the engineer’s plans. When I brought these differences to your attention, you were eager to ensure that we were satisfied with the end result and ended up crediting us for the differences without further discussion.

It is a pleasure to conduct business with a firm that still believes in treating its customers fairly!

Thank you for your cooperation in handling this problem as efficiently as possible.”

“We worked with Greg and D&E for our 60-unit residential project. Greg was professional from start to finish. He worked with us to revise drawings, suggested helpful changes, and always answered his phone when we needed him. D&E’s experience with a variety of projects, means they are able to offer a variety of solutions to fit each situation. In short, Greg is great and we are looking forward to working with him again!”

“Greg and his staff were nothing short of responsive, creative, and easy to work with. Nothing stood in their way and the project was done to our liking in all ways.  We’d hire Greg again in a heartbeat.”
