New pipes. Old home.
Full and partial repiping for Montreal's older homes. Cast iron, galvanized, and lead pipe replacement. Plex and duplex specialists with minimal disruption to tenants.
Every pipe material, properly replaced.
Cast Iron Replacement
Cracked or corroding cast iron drain stacks — the #1 failure point in Montreal plexes. We replace with modern ABS or PVC for decades of reliability.
Galvanized Supply Lines
Galvanized steel corrodes from the inside out, restricting water flow and causing brown water. We replace with copper or PEX for clean, full-pressure water.
Lead Pipe Removal
Pre-1950s homes may still have lead supply lines. We safely remove and replace with modern materials to protect your family's health.
Partial Repiping
Don't need a full repipe? We can replace the worst sections — typically the vertical stacks and main runs — while leaving functional pipes in place.
From assessment to final commissioning.
Assessment
We inspect your entire plumbing system — supply lines, drain stacks, branch lines, and fixtures — to determine what needs replacement and what can stay.
Detailed Plan
You receive a written scope of work with exact pricing, timeline, and a plan to minimize disruption to tenants in multi-unit buildings.
Controlled Execution
We work floor by floor, section by section, restoring water service at the end of each work day. Most homes maintain partial water throughout.
Final Inspection
We pressure-test all new lines, run camera inspections, and coordinate city inspection if required. Backed by our comprehensive warranty.
Montreal repiping done right.
Repiping a plex or older home isn't a weekend project — it requires deep knowledge of Montreal's building eras, pipe materials, and municipal codes. We've been doing this for 15 years and have repiped over 500 Montreal homes.
“Had a 1920s triplex with original cast iron and galvanized throughout. Bella Vita repiped the entire building in under two weeks with minimal disruption to tenants. Incredible work.”
— François G., Rosemont
We know Montreal's old buildings.
Montreal's housing stock spans over a century of construction eras, each with its own pipe materials and plumbing practices. Pre-1930s homes typically have cast iron drain stacks and lead supply lines. The 1940s–1960s era introduced galvanized steel supply lines that are now corroding from the inside out. Even 1970s homes often have early plastic pipes that have become brittle.
Understanding which materials were used in which era — and how they fail — is critical to planning an effective repipe. A plumber without Montreal-specific experience will miss problems that our team catches immediately.
Municipal permit requirements vary by borough and scope of work. Full repipes in most Montreal boroughs require a plumbing permit, and some require engineering sign-off for structural openings. We handle all of this so you don't have to.
