I have had Groupe Royalty install new windows (18) and exterior doors (3) on a major renovation project in my West Island house with extreme satisfaction. This review was based on many elements such as price, quality, installation, service and timing. The team ensured that I am fully satisfied before they left, including a call and a visit by the owner Mr. Tony. I am 100% satisfied with the end result of the overall work done. I recommend this company highly and I would certainly use their service and product in my next project.
