What our clients say

Serge came out this evening for a consultation. He was extremely thorough and knowledgeable. He was also very patient with us as we knew exactly what we wanted.. I would highly recommend giving Unisson a call for any of your window needs.

Terrisa Cosan

Recently we had Unisson do some work on our house in Montreal. They are top-notch in quality but in something else I value–communication. François stayed in touch about our schedules, product options and really helped us make good choices. Then once the work began we could see that he and his team did a top notch job. We are very impressed with the work.

Tom Melville

I am so delighted with Unisson, and the ease of buying a window and not having anything go wrong in any way! It is one of the best buys I have ever made. I am thrilled with the expertise each person has had in meeting my needs. It is such a pleasure to do business with you, and I’m telling everyone I know to get the Unisson to do their work for them. Thanks so much for it all, and God Bless each one of you.
