About Grand-Maison & Fils

Grandmaison is a family story that exists thanks to the perseverance and good advice of Mr. Jean-Guy Grandmaison, the founder. Convinced that the main qualities for success in the garage door field are professionalism and a concern for a job well done, he strove to pass them on within his company. Today, the fruit of his efforts is proven by the satisfaction of each client. What also allows us to stand out at Grandmaison is the quality of our work.
