I had 3 bay windows replaced with triple glazed units in my bathroom reno. Kian was very helpful in recommending that the large unit be one piece and to make one of the smaller windows operable. He also let me know that there is a government rebate and who to contact in that regard. Pricing and workmanship was very good.

I recently used Window and Door Specialist to replace my front door, including a storm door. I shopped around and choose them because they offered the most competitive pricing, and the sales process was very well managed. Ali came and measured my door and provided me with options on different doors, glass inserts and hardware. I had many questions, and all were answered promptly. I was very pleased with the installation as well, and Jack did a very nice job. I would recommend Window and Door Specialist and definitely use them again.

I am very happy with the service. First, the initial response was fast and courteous. Second all questions were answered with patience. Third the work was done for a fair price, and with great skill. I was so pleased with the windows, that I ordered doors also. Highly recommend this team; they’re great.
