      An absolutely delightful experience beginning to end. How refreshing to have integrity in retail and tradesman. Well done and thank you Dayside!


      We had our 7 largest windows and front entrance door replaced with Dayside first week of August in our home in Burlington. My wife and I are very happy with the the quality of the product. Our salesperson was very helpful through the process of choosing from various options. The install team were great, very professional, cleaned up daily, answered all our questions, and did great finishing work. Added bonus, the inside, even our upstairs is cooler even through the heatwave, and much quieter. The front of our home now looks amazing, the new door is stunning. We love it!!!


      Product is wonderful, installation was magnificent. Would highly recommend these Dayside windows to anyone.

      We had 9 windows and our front door replaced. From the salesman to the installers our entire experience with Dayside has been great. The installers are very friendly, hard working and ensured everything is done correctly and totally cleaned up before leaving. The windows and door look absolutely stunning and top quality! I would highly recommend Dayside Windows and Doors.

      Very pleased with everyone from start to finish! My money was well-spent; a lot of people in my community raved on how beautiful the windows are. I said “Dayside Windows in Brantford did it!” P.S. Good help is hard to find!

      From the beginning to the installation, all Dayside personnel were quick, attentive, and responsive. We were impressed with how quickly and professionally [they] responded, and equally impressed by the efficiency, professionalism, and cleanliness of the installation crew. Thank you!
