We just had the most incredible experience with Canadian Choice. Edward the installer did an incredible job! He was very meticulous, took his time on every detail and it shows!
Sasha the salesman was also exceptional! He helped with recommendations, was very responsive on questions and made sure that we were happy with everything! I highly recommend both!
We replaced 2 small bedroom windows, one bathroom window, one very large living room window and two large kitchen windows. Also replaced the old front door and side door. A 3rd bedroom window was converted into a tilt and turn patio door. All looks incredible! The overall look of the house has changed and looks marvelous!
It’s been such a great experience working with Sasha and Canadian Choice Windows and Doors, we are so happy with the results!
Sasha gave us a very competitive quote and walked along side us the whole way. He was patient with our decision and not pushy at all. He happily helped us change our design choice and checked in with us frequently. All scheduling happened promptly and payment was easy and simple.
The team that did the install was friendly and efficient. They made sure we were happy with the job before they left. They even cleaned up so we could hardly notice they were here (if not for the stunning new door of course).
Our home is much more welcoming now, and safer too. Thank you!
