We pride ourselves in providing quality window and door products, and an exceptional installation and replacement service. Read reviews from some of our Ottawa window and door customers.

My husband looked online and called around before deciding on Westend Windows. They ended up doing two basement windows for us. One they had to do from inside and one from outside because our deck wasn’t built yet. They were great about accommodating us with that and said it would be no problem and no extra charge. For window, their prices were good, a little high but comparable to others. We highly recommend them


Homeowner, Ottawa

Just to let you know patio door is installed. It looks fantastic and we couldn’t be more pleased with the two young fellows who installed the door. They were polite, efficient and left the house spotless. I thought I’d have to repaint the the kitchen after you folks were finished and it looks like there was not work done here at all.
We are very pleased with Westend Windows and Doors, from our very first conversation with you, to our meeting with you at our home, to the completion of the installation. We would definitely have not hesitation in having you install windows in the future and recommending your company to friends and family.

I found these guys online when I needed to get a window replaced. They did good job overall. The installer was very good — can’t remember his name because it was a year ago. The price was reasonable and I didn’t have any issues.

I wanted to let you know how pleased I am with the doors. And your installers are very pleasant and polite young men. I will sure recommend your company. We have a lot of people who come through our house on a weekly basis for various meeting and gathering and the doors will get a lot of exposure.
