Our recommendations for Mascouche and its surrounding areas

Portes Bourassa Laliberté offers you products adapted to the reality of people living in Mascouche and Terrebonne. Even though you live in an urban environment, cold, snow, heavy rain and strong winds are still part of your daily life, summer as well as winter. It is therefore important to use materials that will be able to withstand these harsh weather conditions while keeping you warm. We therefore recommend that you opt for an insulated garage door with good thermal resistance so that the garage attached to your house will not be the source of heat loss in your home.
