In 1960, Hector Belanger started as a one-man operation that has now expanded into a third generation family owned and operated business. In 1990, Guy St-Pierre turned his career path around and started his plumbing apprenticeship with Belanger Plumbing. Many hardworking years later, Guy graduated as a plumber and became a partner of Belanger Plumbing. With over 25 years of experience in the plumbing industry and with more than 35 years of management skills, Hector decided to pass on the leadership to Guy in 2018.
