The Real Plumbing Challenges of Homes in Lachine
The housing stock of Lachine is aging — and most homeowners are unaware of the hidden risks in their plumbing system.
The Problem: High Water Table Near the Canal
In Lachine, groundwater levels are often high, increasing backflow risk. We strongly recommend installing a certified RBQ backflow preventer for any property in this area.
The Quebec Construction Code is Not "Guideline" — It's Mandatory
The Quebec Construction Code, Chapter VI – Plumbing, is enforced by the RBQ. Ignoring it is illegal. If you sell or rent, you are responsible for a safe system. We handle all permits and inspections on your behalf — because compliance is not optional.
