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
A bathroom renovation is usually planned ahead: rough-in plumbing comes before finishing. Compare several quotes before setting dates with the contractor.
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Rates and timelines vary by plumber, access and the scope of work, so we do not publish prices without a verifiable source.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: bathroom renovation in Laval
In a bathroom renovation, plumbing needs early planning: where the fixtures go determines the work inside walls and floors.
Before you call
- Decide which fixtures to keep, move or add.
- Check with your municipality whether your project requires a permit.
- Gather photos and measurements of the room.
- Choose your fixtures early: their dimensions guide the rough-in plumbing.
How a typical job goes
- Site visitThe plumber examines existing plumbing, drains and access from the basement or ceiling.
- Detailed quoteThey price the work item by item so you can compare.
- Rough-in plumbingThey install drains and supply lines before walls are closed and finishes go on.
- FinishingThey connect the fixtures, check for leaks and test drainage.
What affects the bill
- Whether drains and water supply lines need to be moved.
- The fixtures chosen: curbless shower, freestanding tub or wall-hung toilet.
- The condition of the existing plumbing and any upgrades it needs.
- Coordination with other trades and the project schedule.
An item-by-item quote makes it easier to compare contractors.
Frequently asked questions
- Do I need a plumber to renovate a bathroom?
- As soon as a drain or water connection is moved, yes: rough plumbing must meet the Code and drainage slopes, otherwise leaks and odours are guaranteed.
- Can I add a bathroom in the basement?
- Yes, often with a sewage ejector pump (macerator) if the drain sits higher than the new fixtures. The plumber assesses feasibility.
- How long does reno plumbing take?
- Rough plumbing for a bathroom usually takes 1 to 3 days, then finishing after the surfaces are installed. The plumber coordinates with the schedule.
- How many plumbers in the directory serve Laval?
- 180 plumbers in the directory serve Laval, including 157 with an RBQ licence number and none offering 24/7 emergency service. Listings with reviews have an average Google rating of 4.8 out of 5 (7,913 reviews). These figures come from published listings and change as the directory evolves.
- How do I choose a plumber for bathroom renovation in Laval?
- 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 Laval show the RBQ licence number and, when available, the Google rating.
