Plumbing that understands the West Island and West End housing stock
A 1928 duplex in NDG and a 1962 bungalow in Dorval have almost nothing in common — except that their original plumbing is running out of road. A galvanized water line rusted shut from the inside, a cast-iron stack cracked at the base, a basement drain that backs up every spring: we recognize these because we've been down in these basements, not just read about them.
Every quote starts with a visit and, when it matters, a camera run down the drain. We explain what's urgent, what can wait a season, and what actually falls to the city rather than the property — a lead or part-lead water service, for instance, is often shared with the municipal network. The price is itemized before any work starts.
We serve Montréal-Ouest, Notre-Dame-de-Grâce, Lachine, Dorval and Pointe-Claire, in French and English.
All services
Cast-iron drain stack repair and replacement
A sewer smell in the basement, a damp stain tracking the stack, a slight sag at the base: century-old cast iron cracks from the inside before it shows on the outside.
Basement floor drain and backup service
Every thaw, the floor drain backs up before the weeping drain can keep up: a sign of a missing check valve or a foundation drain at the end of its life.
Water heater and fixture installation
A new water heater plumbed onto rusted galvanized pipe will never deliver its full flow: we fix the cause, not just the symptom.
