I had found Johnston Glass Ltd. on the website and the service they gave me was exceptional. We needed to have our windows replaced upstairs, Johnston Glass gave me a quick and fair quote and I hired them to install the windows. The staff was very friendly, efficient and knowlagable. They did such a wonderful job on the upstairs windows, that I hired them to cut 2 new basement windows and enlarge a third one. I am very impressed with all the windows and we now have better ventilation as we can open all the windows. Such a difference the basement windows make as we now have lots of natural light coming through. Thank you Johnston Glass for all your hard work and great service!
