Plomberie Outaouais is both the work and the legacy of the St Jean family. The company was founded in 1984 by two brothers, Marc and Yves St-Jean, and built with the help of younger brother Pierre St-Jean who joined the team in 1993.
François St-Jean, the son of Marc, joined as a partner in 2009 to pursue the development and contribute to the success of the business. Leo St. Jean the grandfather of Yves, Marc and Pierre had his own business and plumbing store in Pointe-Gatineau in the 1930's. His son André made his mark in Ottawa in 1960-70's by founding Clearview Plumbing in Vanier.
It was the largest plumbing company in Ottawa at the time. The fact that this is a fourth generation of plumbers is certainly no stranger to the continued success of Plomberie Outaouais / Plomberium.
