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
Freeze-related leaks often show up during the thaw, in late winter and spring, when a pipe cracked by the cold starts flowing again. Keep an eye on exterior walls and water inlets.
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Rates and timelines vary by plumber, access and the scope of work, so we do not publish prices without a verifiable source.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: water leak detection in Longueuil
A hidden water leak often does more damage than a visible one: finding it precisely avoids opening walls for nothing.
Before you call
- Shut off the supply to the affected fixture or the main water inlet.
- Watch your water meter: if it keeps moving with everything off, the leak is probably hidden.
- Take photos of stains, swelling and any signs of mould.
- Clear access to the affected walls, ceilings and cabinets.
How a typical job goes
- Finding the leakThe plumber inspects the affected areas and, depending on their equipment, uses a moisture meter or thermal camera.
- Targeted openingIf the leak is inside a wall or ceiling, they open only the area needed.
- RepairThey replace the faulty section of pipe or fitting.
- Checking the workThey restore water pressure, check for leaks and advise you on drying out.
What affects the bill
- The time needed to locate a leak that is not visible.
- Opening walls or ceilings, then restoring them.
- The type of pipe involved: copper, PEX, cast iron or another material.
- How much secondary damage needs to be dried out or repaired.
Have the quote state whether restoring opened surfaces is included.
Frequently asked questions
- How do I know if I have a hidden leak?
- Read your water meter at night, then in the morning with no usage: an increase means a leak. Persistent dampness or an abnormal bill are other signs.
- Do walls have to be torn out to find a leak?
- No. Acoustic and thermal detection pinpoints the leak precisely; only the affected area is opened, which lowers repair costs.
- Is a leak covered by insurance?
- Sudden accidental damage is often covered, slow wear rarely is. Document everything and check your policy; the plumber can provide a report.
- How many plumbers in the directory serve Longueuil?
- 64 plumbers in the directory serve Longueuil, including 51 with an RBQ licence number and none offering 24/7 emergency service. Listings with reviews have an average Google rating of 4.5 out of 5 (1,713 reviews). These figures come from published listings and change as the directory evolves.
- How do I choose a plumber for water leak detection in Longueuil?
- Check the contractor's licence in the RBQ public registry, ask for a written quote describing the work and the warranty, and usually compare two or three proposals. Listings for Longueuil show the RBQ licence number and, when available, the Google rating.
