Check a plumbing contractor’s licence in Québec

Ask for two precise details

Before authorizing work, ask for:

• the legal name of the business that will appear on the estimate and invoice;
• its contractor licence number.

In Québec, the licence belongs to the contractor offering or arranging the work. “Plumber” may also refer to an employee doing the work. Check the contracting business, not only the first name of the person who arrives.

Check current official sources

1. Search the name or number in the Régie du bâtiment du Québec licence registry.
2. Compare the legal name with the estimate. Check the licence status and listed subclasses. Ask the RBQ or CMMTQ when you are unsure which subclass applies.
3. Consult the CMMTQ member directory to check the plumbing and heating business.
4. You can also use the Office de la protection du consommateur’s Getting informed about a merchant tool. No result on its own is not proof that a business is or is not reliable.

Record the verification date. A logo, advertisement, or old screenshot does not replace checking the official registry when you make the decision.

Check separately what a licence does not prove

A valid licence does not tell you the price, availability, future work quality, or service terms. Ask separately for proof of liability insurance and a written description of the work, billing method, and applicable conditions.

Plombier Connect’s role

Plombier Connect is an independent matching service, not a plumbing contractor. A partner business’s licence never becomes the platform’s licence. You can repeat the official checks before hiring the proposed professional.

For the rest of your comparison, review the questions to ask before choosing a plumber.

Frequently asked questions

Does a valid licence guarantee the result?

No. It confirms regulatory information at the time of the check, but it does not guarantee price, timing, or future results. Also check identity, insurance, scope, and written terms.

When should I check again?

Check when choosing the business and compare the result with the name on the estimate and invoice. Keep the date and source you consulted.
