Who we are

A family business, a team that stays.

Founded in 2004 in Deux-Montagnes by Yvan Dumoulin, a carpenter’s son, Dumoulin Doors and Windows became a family passion: Sylvie Bisson came on board, then Nicolas and Gabriel after their studies. Alongside long-standing installers and sales reps on the North Shore, we aim for turnkey service — from advice through to window coverings. Your project, our passion.
