“I am really satisfied with the way the guy installed the windows and how he went about making sure that none of the materials were left around outside or inside the house. He also had a nice and pleasant attitude.”

Melford K.

“Mad City Windows installed new windows quickly and efficiently. They were professional in their interaction with me, courteous, and friendly. I would definitely recommend them for any project in the future.”

Frank P.

“We had Mad City come out and give us a quote, and the salesman provided a good demonstration of the ways the heat and cold don't permeate the windows. He seemed very organized. We had another salesperson from another company come out, and the difference was like night and day; they did not provide us with a demonstration. We were very impressed with the presentation of the product that Mad City provided, and we are impressed with the quality of the product. I also like their lifetime warranty, and we enjoyed the efficiency of the installer.”


“I would like to recognize my salesman. He also had a guy with him who was learning the job. I respect both of those men. I also liked the three men who put the windows in. A man came here and there was a bottom window that had to be replaced. He did that all on time. They did a very good job.”


“So far I am pleased with their work, and how they have handled their customer service. I felt as if they appreciated me as a customer. As with any business you deal with, it is not the problems they have but how well they can resolve any issues. Luckily, I did not have any problems with Mad City, but if I had I feel confident they would resolve them fairly and quickly.”


“My installation crew from Mad City was very professional. I'm a disabled person in a wheelchair, and they even cleaned my garage for me. They did over and above what they needed to do. They were very professional.”

Ervin S.

“Tyler was great! All the men were very kind, very well-mannered, and quite careful. You were very communicative, explaining what you were going to do to the roof, explained why and what was required.”
