The Real Plumbing Challenges of Homes in Longueuil
The housing stock of Longueuil is aging — and most homeowners are unaware of the hidden risks in their plumbing system.
Problem: Lead Water Pipes and Regulatory Compliance
Many Longueuil homes, especially in older neighborhoods, still have lead service pipes. This material poses a health risk. While replacement is strongly recommended by authorities, it’s often only undertaken when visible problems occur. Plomberie Despaties proposes inspections to identify these pipes and performs their replacement with certified and safe materials, ensuring your water quality and installation compliance.
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.
