Trusted residential and commercial plumbing across Hull, Aylmer, the Gatineau sector, Buckingham, and Masson-Angers. From a midnight burst pipe to a planned bathroom renovation, we handle Outaouais plumbing the way it should be done — to the Québec Construction Code, with a written quote before any work begins.
Gatineau Plomberie is a plumbing company built around a simple idea: the Outaouais is a distinct place, and plumbing here has to be done for this place. The Ottawa River runs along our southern edge, the Gatineau and Lièvre rivers cut through the city, and our winters routinely drive frost deep into the ground.
That combination shapes everything we do, from how we protect a basement against sewer backup to how we insulate a vulnerable supply line before the first hard freeze. We focus on plumbing and only plumbing — water supply systems, wastewater drainage, venting, fixtures, water heaters, and the diagnostic and emergency work that keeps them running.
Specialization is not a marketing line for us — it is how a plumber stays genuinely current with a code that changes. The plumbing rules in Québec were updated when the amended Chapter III of the Construction Code came into force on July 11, 2024, adopting the National Plumbing Code of Canada 2020; any new plumbing system installed after January 11, 2025 must comply with it. Keeping pace with changes like that is a full-time commitment, and it is the commitment we have made.
Our team brings years of hands-on experience across the region’s housing stock — from pre-1955 homes in Vieux-Hull and Pointe-Gatineau with their aging clay drains and galvanized supply lines, to the new construction filling out Le Plateau and the western Aylmer waterfront. We know that a 1960s Gatineau-sector bungalow hides different problems than a downtown Hull condo, and we price and plan accordingly. What you will not find here is a sales pitch built on slogans. You will find plumbers who explain what is wrong, what the code requires, what your options cost, and what we recommend — in plain French or English.
No verbal estimates that drift upward, no surprises on the invoice — just code-compliant work, documented at every stage.
We are not a general renovation outfit that also does some plumbing. Supply, drainage, venting — that is our entire focus, which is why we stay current with the National Plumbing Code of Canada 2020 as adopted by Québec and with the City of Gatineau’s own construction by-law.
The City of Gatineau requires a permit for a range of plumbing work — backwater valve installation, replacement of a foundation drain or water service line, and adding a bathroom. We manage the municipal permit process so your work is documented and compliant, and we leave you with the paperwork.
Repeated freeze-thaw cycles near the Ottawa River crack aging foundation drains and burst under-insulated supply lines every winter. We install, insulate, and protect with our climate in mind — because a pipe that survives a Toronto winter can still fail in Gatineau.
We document the diagnosis, the scope, the parts used, and the completed work. For subsidy-eligible jobs such as backwater valves, that documentation — model, part number, labour, and taxes — is exactly what the City of Gatineau requires for its anti-backflow subsidy program.
Gatineau’s by-law requires every property owner to have a backwater valve, regardless of the home’s age, installed on secondary branch lines rather than the main, with the foundation drain protected as well. We install valves that meet the recognized CSA and NQ standards and remain accessible for the twice-yearly maintenance the by-law expects.
After an on-site assessment you receive a written, fixed-price quote. We stand behind the work with a written warranty, and all documentation is available on request. No verbal estimates that drift upward, no surprises on the invoice.
Every range below is indicative, based on published 2026 Québec and Canadian market pricing. Your price is the written quote you receive after an on-site assessment. Ranges describe the market, not a fixed offer.
Burst pipes, sewer backups, no water, flooding — these do not wait for business hours. We respond across Gatineau day and night, isolate the problem fast, and stabilize your home before damage spreads. After-hours, weekend, and statutory-holiday calls carry a premium rate, which we confirm before dispatch.
Tank and tankless, electric and gas. Gatineau’s mineral-rich water accelerates tank corrosion, so eventual replacement is normal. We size the unit to your household, handle the required safety drain and drip pan, and connect it to code. Heat-pump (hybrid) models are increasingly popular thanks to provincial energy rebates.
Slow drains, recurring clogs, and main-line blockages cleared with snaking, hydro-jetting, and camera inspection. A camera locates the real cause — roots, grease, a collapsed clay section — instead of just pushing the problem downstream. Especially common in older Hull and Pointe-Gatineau drainage.
Required by City of Gatineau by-law on every property. We install “normally open” or “normally closed” valves meeting CSA B70 / CAN-CSA-B181 and NQ 3632-670 standards, on secondary branch lines with the foundation drain protected, and positioned to stay accessible for inspection. Eligible installations may qualify for the city’s anti-backflow subsidy.
Faucets, sinks, toilets, showers, and tubs supplied and installed. We set low-flow fixtures that meet the city’s water-efficiency provisions and verify proper venting and seals so you do not trade one leak for another.
Safe thawing of frozen lines, emergency repair of burst pipes, and preventive insulation before the cold sets in. Methods vary by piping material and the extent of the freeze; we choose the approach that thaws effectively without cracking the pipe.
Replacement of distribution piping in older or renovated homes where copper, galvanized, or polybutylene shows corrosion. Québec plumbers now favour PEX for its freeze resistance and easier routing through existing walls. A typical bungalow project runs three to five days depending on access.
Pinpoint diagnosis before anyone opens a wall or digs a trench. We use pipe-inspection cameras to map drains, confirm the cause of recurring backups, and document the condition of a line — useful for a basement renovation or a pre-purchase inspection.
Not sure which service you need? Describe the problem at (613) 324-9141 and we’ll tell you straight — then put it in writing.
The ranges below are benchmarked against published 2026 Québec and Canadian plumbing-market pricing. They are provided so you can budget with realistic expectations — they are not an offer to contract.
Your price is the written quote you approve after an on-site assessment. The table reflects the market, not a fixed offer.
The age and accessibility of your plumbing, the materials chosen, whether the work is scheduled or an after-hours emergency, the season — winter freeze season drives demand — and any unforeseen conditions found once work begins.
The published reference rate for certain regulated plumbing activities in Québec was indexed on January 1, 2026, illustrating how even official tariffs shift year to year. We quote against current figures.
Labour, materials, permits, and taxes are shown separately. The number you approve is the number you pay — unforeseen conditions are disclosed and re-quoted before we proceed.
Recognize your problem below? We’ll book an on-site assessment at no cost and no obligation.
When heavy Outaouais rain or rapid snowmelt overwhelms the municipal network, wastewater can push back into basements that lack proper protection. This is exactly why Gatineau’s by-law makes a backwater valve mandatory on every property. We assess your existing protection, install or correct valves to standard, and document the work for the city’s subsidy program.
Deep frost and repeated freeze-thaw near the rivers crack foundation drains and burst under-insulated lines every winter, particularly in pre-1980 homes in the Hull and Pointe-Gatineau sectors. We thaw safely, repair the break, and insulate vulnerable runs so the same pipe does not fail again next January.
Galvanized, early copper, and polybutylene piping in homes built before 1980 corrode from the inside, dropping pressure and risking water damage. We diagnose the real condition with a camera and supply line testing, then repair the section or recommend repiping in freeze-resistant PEX.
Gatineau’s hard water shortens tank life. When a heater leaks, runs out fast, or fails entirely, we right-size the replacement, install the required safety drain and pan, and connect it to code — including the electrical or gas considerations the unit demands.
Roots in clay drains, grease buildup, and partial collapses cause clogs that keep coming back after a quick snake. A camera inspection finds the true cause so the fix actually holds, rather than returning in a month.
Renovations and DIY plumbing sometimes leave behind venting errors, improper backwater valve placement on the main line, or fixtures that do not meet current code. We identify what does not conform and bring it up to the standard the Québec Construction Code and the city by-law require.
Use this checklist whether you hire us or anyone else. It is the standard every Gatineau homeowner is entitled to expect.
From the first call to the final walkthrough — documented, code-compliant, and approved in writing before any work begins.
Call (613) 324-9141 or submit our contact form. For emergencies we dispatch right away; for planned work we book a convenient assessment.
We come to your Gatineau property, diagnose the real problem — not just the obvious symptom — and check for underlying issues that could cause a repeat failure.
You receive an itemized quote in writing, with labour, materials, permits, and taxes shown separately. No work begins until you approve it.
Where the City of Gatineau requires a permit — backwater valve, water service, foundation drain, added bathroom — we manage the municipal process for you.
Our plumbers complete the work to the Québec Construction Code, with the inspection stages a compliant installation requires.
We review the completed work with you, deliver your written warranty, and provide the documentation — model numbers, part numbers, invoices — you may need for a subsidy claim or a future sale.
We serve all five sectors of the City of Gatineau and the surrounding Outaouais communities. If your neighbourhood is not listed, call — we very likely cover it.
All service is within Québec. Work across the river in Ontario requires different provincial licensing, so we keep our plumbing services on the Québec side where our RBQ credentials apply. Serving your corner of the Outaouais — call (613) 324-9141 to confirm coverage and book an assessment.
The code, the licensing, the by-laws, and the climate that shape every plumbing job in the Outaouais.
Plumbing in Québec is governed by Chapter III – Plumbing of the Construction Code, together with Chapter I of the Safety Code, administered by the Régie du bâtiment du Québec (RBQ). The amended Chapter III came into force on July 11, 2024 and adopts the National Plumbing Code of Canada 2020 with Québec amendments. Any new plumbing system installed after January 11, 2025 must comply with it. This is the standard we build to on every job.
To carry out plumbing work in Québec, a contractor must hold the appropriate RBQ licence, including subclass 15.5, Contractor – plumbing. The Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ) acts as the RBQ’s mandatary, verifying the qualifications of plumbing and heating contractors and administering the qualification exams. As a property owner, you are responsible for ensuring your plumbing work goes only to properly licensed contractors.
The City of Gatineau requires every property owner to install a backwater valve (clapet antiretour), regardless of when the home was built. The by-law specifies that valves go on secondary branch lines — never the main residential line — and that the foundation drain must also be protected. Valves must stay accessible so they can be inspected and serviced, which the city recommends doing twice a year, typically at the spring and fall time changes.
Gatineau offers a subsidy program toward eligible anti-backflow devices — backwater valves and certain sump-related protections — to reduce basement sewer-backup risk. Eligible work must comply with municipal regulations and recognized standards (such as CSA B70, CAN-CSA-B181.1/.2, and NQ 3632-670) and must be installed by a contractor holding an active RBQ licence, with an itemized invoice showing device model, part number, labour, and taxes. We document our installations to exactly this standard so a claim is straightforward.
The City of Gatineau requires a municipal permit for a range of plumbing work, which can include backwater valve installation, replacement of a foundation (French) drain or water service line, adding a bathroom, and water-heater replacement in certain sectors. Gatineau’s construction by-law also sets local provisions — low-flow toilets, wastewater disposal, potable-water supply, and backwater protection among them. We confirm what your specific job requires and handle the application.
Gatineau sits on the north shore of the Ottawa River and stretches east and west of the Gatineau River. Deep winter frost and frequent freeze-thaw cycles stress foundation drains and supply lines, while the region’s hard, mineral-rich water shortens water-heater life. The housing stock spans pre-1955 homes in Vieux-Hull, Pointe-Gatineau, and parts of Aylmer — often with clay drains and dated supply piping — through to new PEX-plumbed construction in Le Plateau and along the Aylmer waterfront. Good Gatineau plumbing accounts for all of it.
General neighbourhood attribution. Every job is backed by a written quote and full documentation.
Our basement backed up during a heavy spring rain. They installed a backwater valve on the branch line, walked us through the city by-law, and gave us the paperwork we needed for the subsidy. Clear and professional.
Water heater died on a Sunday. They confirmed the after-hours rate up front, replaced it the same day, and the final invoice matched the quote exactly. That kind of honesty is rare.
They camera-inspected our old drain before quoting, found a collapsed clay section we never knew about, and explained the options in plain English. We finally fixed the recurring clog for good.
Repiped our 1970s bungalow in PEX over four days. They protected the work areas, kept us informed, and left the documentation tidy for our records.
Pipes froze during a January cold snap. They thawed the line safely and then insulated the run so it wouldn’t happen again. Bilingual service made the whole thing easy for my parents.
Booked them for a bathroom addition. They handled the municipal permit, did the rough-in to code, and the inspection passed without a hitch. No surprises anywhere.
