"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."

"All went well. The gentleman who was doing the cleaning arrived on time, reviewed everything that was to be done and updated the quote to reflect the total number of windows involved. I also asked that he clean the window sills. He started the cleaning and completed the work in less than 3 hours. All nicely done."

"Paul and his team were great. We replaced most of our windows as well as an old wooden window. We were concerned that the replacement for the wooden window wouldn’t come out as nicely but the replacement was beautiful! We are looking forward to our electric bill this summer."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."
