Our values define us

At Étanchéité Totale, family values ​​are important to us.


What was a small business in the 1960s with commercial buildings has now become a dual-sector power for commercial and residential projects. This is thanks to the family ties.

Marcel Leroux has entrusted his son Roger with the enormous responsibility of supervising his own team at eighteen. Marcel quickly understood that his son’s commitment was sincere, and there is no better way to learn than to go headlong.

Roger knew from an early age that he wanted to be a specialist in the art that inspired the name of the company: the waterproofing. After spending four hours working for someone else, he said, “This is not for me. And then, he decided to join his father, contributing to the growth and success of Total Waterproofing, which now meets the needs of customers on the South Shore and the Island of Montreal.

Similarly, Roger’s son, Alain, knew what future was in store for him: he wanted to work side by side with his father to continue and solidify the family tradition. Alain was thirteen when he started working and he has not stopped since. Today, Roger is in charge of business management, while Alain is at the head of operations. Together, they are an unbeatable team.


Family values, including honesty, respect, discipline and dedication, are cherished by Total Waterproofness. We reinforce these values ​​with our projects, our team, and especially our partners and our customers.

At the forefront of residential, commercial and industrial caulking.


Happy customers
