Kanata Windows Testimonials


“Big City Windows and Doors replaced all 15 of my windows as well as my front door and delivered a quality service from beginning to end. Their sales manager answered all of my questions, clarified the differences between window types, and was able to suggest appropriate upgrades, such as for a basement bedroom window, to ensure my house maintained its value well into the future. Their installers were skilled, courteous, and professional at all times and demonstrated teamwork and coordination. Their office staff were equally amazing, being efficient and responsive to my needs. They will be my first call for any future home upgrades or repairs.”


“We saw their booth at the home show. They sent a rep out to visit us and showed us a video of the manufacturing process. From initial consultation to installation, everything was exactly the price quoted, which we felt was good value for money. Every member of their team we dealt with was super professional, and we felt that they cared about us as customers. We ultimately had four windows installed, including a replacement octagonal window which turned out fantastic. They even made a recommendation for our kitchen window overlooking our deck that made the kitchen brighter (removing a cross piece), allows for better airflow, and it no longer interferes with our patio umbrella. The best part is the 25 year warranty. While we now have to move for work, it's nice to know the warranty is transferrable so we can use this as a selling point. Definitely would recommend Big City Windows.”


"Great experience. The installers went above and beyond, helping with a difficult basement installation and removing original 70yo windows set in cement. I highly recommend! I will be a return customer for my other window needs.
