"I highly recommend Clifton Contracting. The owner and all his employees are great to work with and did an excellent job installing my egress window. They even worked with me to take care of some other home to-do's on the fly. I would happily use them again."

"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."

"Very well. The technical was prompt and he installed the film precisely. The entire process took about 90 minutes and we are experiencing less heat inside as a result of the film. One unexpected benefit is that the view from the inside of my is actually clearer and cleaner than before the film was installed. I am already planning to have more windows done."
