Trusted Plumber in Montreal
When a pipe bursts, a drain backs up, or a water heater gives out, you don't have time to research. You need a plumber who picks up the phone, tells you the price upfront, and shows up when they say they will. Plomberie 5 Étoiles has been doing exactly that in Montreal for over 15 years — serving homeowners, condo owners, property managers, and small commercial clients across every borough in the city.

Emergency Plumber in Montreal — 24/7
Plumbing emergencies don't follow a schedule. A pipe that bursts at 2am on a Saturday, a basement flooding during a spring storm, a water heater failing the night before a family event — these situations need an immediate response, not a voicemail.
We answer emergency calls around the clock across Montreal and the surrounding area. When you call, you speak with a real person, not a recording. Our dispatcher confirms an ETA and a plumber arrives with the tools and parts needed to resolve most emergencies in a single visit.
Common emergencies we respond to:
- Burst or leaking pipes inside walls, ceilings, or basements
- Sewer backup flooding into drains or fixtures
- Completely blocked main drain with backup into multiple fixtures
- No hot water — failed water heater
- Overflowing toilet that won't shut off
- Frozen pipes in winter — preventing flow or causing rupture risk
- Active water leak with no accessible shut-off
For emergencies: call 514-447-3700 directly. Don't fill out a web form — call the number.
Plumbing in Montreal — What Makes This City Different
If you've lived in Montreal for a while, you know the city's housing stock has its own plumbing personality. The quirks that show up in Montreal homes — in a Plateau triplex, a Rosemont duplex, an NDG semi-detached, or a Griffintown condo — aren't always the same as what a plumber encounters in a newer suburb. We've worked in these buildings for 15 years. Here's what we've learned.
Cast Iron Drain Systems
An enormous share of Montreal's residential buildings — everything built before the mid-1970s — was plumbed with cast iron drain pipes. That includes most of the triplexes, duplexes, and row houses that define Montreal's older neighbourhoods. Cast iron is durable, but it corrodes from the inside out. After 50+ years, the rough, pitted interior surface traps debris and causes recurring clogs. Sections can crack, belly, or partially collapse. If you're dealing with recurring drain problems in an older home, the issue may not be what you're putting down the drain — it may be the condition of the cast iron itself. A camera inspection tells you exactly what's happening inside the pipe before you spend money on repeated cleaning.
Spring Sewer Backup Season
Montreal's spring snowmelt, combined with heavy spring rainfall, puts enormous pressure on the city's sewer infrastructure every year. During high-inflow events, sewer mains can surcharge — forcing wastewater backward through the lateral drains connected to homes. If your home doesn't have a backwater valve installed, a sewer backup can push sewage up through your basement floor drain, laundry tub, or lower-level toilets with no warning. A backwater valve is the single most effective flood protection measure for a Montreal basement, and we install them regularly across the city.
Triplexes, Duplexes, and Shared Plumbing Stacks
Multi-unit buildings in Montreal share vertical drain stacks and, in many cases, share horizontal drain runs. A clog in one unit's drain can affect water flow in another. Shared stacks in older buildings — where the cast iron is 50+ years old — sometimes develop partial obstructions in the common section that cause recurring problems for multiple tenants. We work with property owners and managers regularly on these inter-unit plumbing issues, and we know how to diagnose whether a problem is isolated to one unit or systemic to the building.
Condos — Access Panels, Strata Rules, and Permit Requirements
Condo plumbing in Montreal has its own complications. Many condo buildings require that plumbing work be performed by a licensed contractor with documentation provided to the strata. Access to shut-off valves and drain cleanouts may be behind drywall or in utility spaces shared with adjacent units. We've worked in dozens of Montreal condo buildings and know how to navigate these constraints — getting the work done cleanly without creating access problems or strata headaches for you.

What to Expect When You Call Us
A lot of homeowners have had bad experiences with plumbers — surprise charges, no-shows, or a technician who arrives without the parts needed to finish the job. We've built our business by doing the opposite.
When you call: You speak with someone immediately. We ask a few questions about what's happening, and in most cases we can give you a price range over the phone before sending a plumber. No surprises.
When the plumber arrives: The job is assessed on-site and a firm price is confirmed before any work begins. You don't get an invoice that's double the estimate.
During the job: We protect your floors and work areas. We don't leave a mess. If we find something unexpected during the job — a pipe condition that changes the scope — we stop, explain it, and get your approval before proceeding.
After the job: We confirm the fix is working before we leave. If you have questions about maintenance or what to watch for, we'll answer them.
