Rules in Québec
- Québec's building authority (RBQ) recommends hiring a contractor who holds an RBQ licence before signing a contract: this gives you access to a financial guarantee if a dispute arises.
- The listings in this directory come from active licences in subcategory 15.5 (plumbing) of the RBQ registry. You can check a licence number in the public registry.
- The CMMTQ also advises checking that the contractor is a member of the Corporation and holds the licence subcategories required for your work.
Official sources
Seasonality
Emergency calls often peak in winter, when pipes freeze, and during heavy rain or snowmelt, when sewer backups become more frequent.
Prices and timelines
Rates and timelines vary by plumber, access and the scope of work, so we do not publish prices without a verifiable source. Ask for a written quote that specifies the nature and duration of the parts and labour warranty, as the CMMTQ recommends.
Guide: 24/7 emergency plumbing in Longueuil
In an emergency, a few simple steps limit the damage and save the plumber time as soon as they arrive.
Before you call
- Shut off the main water supply or the shut-off valve closest to the leak.
- Cut power to the affected area if water is getting close to outlets or the electrical panel.
- Take photos of the damage before cleaning up: your insurer will ask for them.
- Note how long the problem has been going on and what you have already tried.
How a typical job goes
- Call and triageYou describe the situation and the plumber confirms availability and arrival time.
- Making it safeThey stop the flow, protect nearby areas and assess how far the damage goes.
- Repair or temporary fixDepending on the parts on hand, they repair on site or install a reliable temporary fix.
- Follow-up workThey give you a written quote for any additional repairs that are needed.
What affects the bill
- When you call: evenings, nights, weekends and holidays usually cost more.
- The distance and travel time to your home.
- The type of work: a temporary patch or a complete repair.
- The parts to replace and access to the pipe, for example behind a finished wall.
Before confirming, ask on the phone how travel and emergency work are billed.
