We would highly recommend Window Seal West for any window replacement. Mike, our sales rep was excellent in explaining everything. The installers were very efficient, tidy and respectful with good quality work.

We had a large front window replaced, the Sales person was very knowledgeable, took the time to listen to our concerns and recommended a solution to meet our needs. The Installation Team were GREAT, they were very professional and cleaned up when they were done. They walked through the process during the installation, answered all my questions and ensured I was satisfied before leaving.

Triple Pane primary bedroom window replacement done extremely competently a few years ago (including preserving custom finishing carpentry). Amazing job by Jim and his team. This week one of the cranks would not allow the window to close. Jim popped by and very quickly repaired the issue. So grateful to have help with the warranty, even tho it was a very small issue (but beyond my skills). Highly recommend this company and their team they are competent, respectful, responsive, trustworthy.
