I had such a great experience with Vitaliy and his team. I needed a custom glass window, and they made it happen quickly and seamlessly -and it was a perfect fit! Everyone was friendly and easy to work with, super efficient and they did a fantastic job -I definitely recommend them! It was pleasure.

Had two windows replaced by Korsun Windows.  Very professionally done.  The installers were pleasant and easy to talk with as we asked questions.  Would highly recommend.

In late October 2024 we had our front large 3 section picture window replaced with a triple pane one.  Everything went smoothly and the workers were very efficient and excellent to deal with.  However, after later inspecting the window, 2 of the sections had 2 small defects on the inner and outer glass from the manufacturer.  Upon addressing these issues, I was reassured that the 2 sections would be replaced under warranty.  After a few weeks wait they came and installed the replacement sections without any questions or incidence.  I highly recommend this company and want to thank Vitaliy for taking care of the issue.  I wouldn't hesitate to use them again.

Excellent service. Crew on time and very professional.  Very pleased with the product. Windows look great, from the inside and outside. We would highly recommend Korsun Windows. We also requested a quote to replace our basement windows.
