"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."

"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."

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."
