Windows Installation in Ottawa

“Very happy with the final results, the intsallers were very professionals, everything was cleaned up afterward.“

“We had our home reshingled by Kovar Contracting in June 2025, and we couldn’t be happier with the entire experience. From our initial contact to the in-person quote and through to the completion of the project, the service was exceptional. The team that arrived to do the work was punctual, professional, and respectful throughout. They worked efficiently, did a fantastic job, and left everything clean and tidy when they were done. We highly recommend Kovar Contracting to anyone looking for reliable, high-quality roofing work. Thanks again for a job well done!“

“Evgueni and his team replaced all the windows and all exterior doors in our house. We are very happy with the results. The quality and attention to detail are great; the windows are beautiful and solid. The team had a lot of experience and they dealt with any surprises and issues right away. There was always someone senior double-checking that everything was done the right way. Highly recommended.“

“Took on a smaller job when several other businesses refused to help. Workers were very polite and worked diligently. I highly recommend Centennial Glass for your requirements.“

“Hired these guys to replace 2 aging slider windows with asymmetric single-hung windows (see picture). The whole job took about 2 and a half hours. They were extremely organized and efficient, worked quickly and carefully, cleaned up after themselves well. The new windows are amazing, I'm really happy with the result. 10/10 would recommend for anyone looking to replace windows in Ottawa!“

“Top quality custom screen provider in Ottawa. Very friendly and professional staff. Highly highly recommended“

“We had all our windows and a patio sliding door replaced, good quality on the product and installation for a very reasonable price. The installer even fixed the posts where previous poor siding installation (not by this company) had caused the former posts to completely rot away (how our old windows were still in place, I will never know). Great piece of mind and appreciate they did that work at no extra cost or stress on us as the homeowners. The minute after the first window was installed and sealed, I noticed an immediate difference in both the temperature and noise level of the house. I’ll update this review if any issues arise in later years but I really don’t anticipate that happening.

We have felt very taken care of from the moment Aleks first walked through our door, and will be calling BestCan first for any future work on our house. We had numerous quotes from many companies and this was the best fit for our budget and needs.“
