Find Local Contractors

Find help replacing polybutylene plumbing anywhere in Canada: send a request to the HAUSE desk, open your city’s guide, and check any contractor’s credentials before you sign.

How this page works

A request desk, not a ratings list

This page used to promise a searchable list of contractors. We no longer publish one. Star ratings and “verified” badges on a website are only as good as whoever checked them, and a homeowner deserves to see the actual certificate, licence and written quote rather than a badge.

Instead, Polybutylene.ca, part of the HAUSE Network, runs a request desk. You describe your home and what you need; the desk replies with next steps and, where available and with your consent, a local contractor who can inspect and quote. HAUSE is not a plumbing contractor, does not do the work, and does not certify or endorse the businesses it introduces. Whoever you hire, use the vetting guide below.

How the HAUSE request desk works

The same form sits on this page, the replacement guide and the city pages.

  1. Send your details

    Give your name, email, optional phone, province, city, approximate home size, number of bathrooms, preferred replacement material and anything the desk should know, such as a recent leak, an insurance deadline or a condo board. Tick the consent box so the desk can reply.

  2. The desk reviews the request

    The desk replies with next steps: links to the right guides, questions about your home, and what to have ready, such as photos of exposed pipe or your insurer’s letter.

  3. Introduction, only with your consent

    Where a contractor serving your area is available, the desk asks before sharing your details. If none is available, you still get the guidance and can look for a plumber on your own.

  4. Site visit and written quote

    The contractor confirms the pipe type, measures the job and quotes in writing. Compare it with the published price ranges and at least one other quote.

  5. You decide

    Nothing is booked until you sign with the contractor. The agreement, the permit and the warranty are between you and them, so check their credentials first.

Pick a city to open its poly-B guide, or tap a province to see who certifies plumbers there and how to check a licence.

What the model shows, in words

Using the map

Every pin on this map is a city with its own poly-B guide on this site, from Victoria and the Lower Mainland through Kelowna, Calgary and Edmonton to Ottawa and the Greater Toronto Area. Selecting a pin opens that city’s hub, where neighbourhood pages explain local building eras and what they suggest about the chance of finding poly-B. Selecting a province instead shows the body that certifies plumbers there, whether certification is compulsory, and where to check a tradesperson’s credentials.

Western Canada

Alberta requires a recognized certificate or registered apprenticeship to install or repair plumbing, and its Tradesecrets tool lets you look up a certificate by name and number. British Columbia offers plumber certification through SkilledTradesBC, but plumber was not among the seven trades requiring certification when we checked, so asking for proof matters more there. Saskatchewan lists plumber as a compulsory trade; Manitoba lists it as voluntary. In each province the permit for a repipe comes from the municipality.

Ontario and Quebec

Ontario treats plumber as a compulsory trade: anyone practising must hold a training agreement or certificate and appear on Skilled Trades Ontario’s public register, which you can search. In Quebec, plumbing work requires a contractor licence from the Régie du bâtiment du Québec, issued for plumbing and heating through the CMMTQ, whose member directory is searchable by company name, street, city or phone number. Both provinces give homeowners a direct way to confirm a claim before signing anything.

Atlantic Canada and the North

New Brunswick requires plumbing construction work to be done by a provincially licensed plumber working for a licensed plumbing contractor. Nova Scotia lists plumber among its thirteen compulsory certified trades and can fine uncertified work. For Prince Edward Island and Newfoundland and Labrador we could not confirm the current rules from an official page, and the territories publish little; plumber is a Red Seal trade everywhere in Canada, so a Red Seal endorsement is a useful baseline to ask about.

Vetting

How to vet a poly-B replacement contractor in Canada

A whole-home repipe opens your walls, changes every water line in the house and becomes the evidence your insurer and future buyers rely on. Checking the people doing it takes an evening and is worth it.

  1. Confirm trade certification. Ask for the certificate or licence number of the plumber who will do the work, not just the company name, and check it with the provincial body in the table below. Plumber is a Red Seal trade in every province and territory, so a Red Seal endorsement shows the person passed the national exam.17
  2. Check the business side. In Quebec, confirm the company’s RBQ licence and CMMTQ membership.1213 In Alberta, a contractor that takes a deposit for work on your home and signs the contract away from its own premises needs a provincial prepaid contracting licence.5 In Edmonton, contractors must also be licensed with the City.2
  3. Ask who pulls the permit. In Calgary, a hired contractor applies for its own plumbing permit; a homeowner permit is only for owners doing the work themselves.1 A contractor who suggests skipping the permit is also skipping the inspection that protects you.
  4. Ask for references from recent repipes, ideally jobs of a similar size, and call them.19
  5. Get the warranty terms in writing for both labour and materials, and understand how a claim would work.19
  6. Ask for proof of liability insurance and of workers’ compensation coverage where it applies, so an injury or accident on your property is not your problem.
  7. Compare at least two written quotes line by line using the checklist on the replacement guide.

The City of Calgary publishes its own five steps for choosing a contractor, a useful companion wherever you live.1

Who certifies plumbers, province by province

Checked against official pages on 2026-09-28. “Compulsory” means a person must be certified or registered as an apprentice to do the work.

Rules change; confirm with the provincial body before you rely on this table. Plumbing and building permits are issued by municipalities, which may add their own contractor licensing, as Edmonton does.2 In British Columbia, gas fitter certificates have been issued by Technical Safety BC, and the City of Vancouver requires a plumbing permit for most plumbing work.618

Questions to ask before you hire

Grouped the way homeowners usually work through them. Tick them off during the site visit.

0 of 15 checked

Red flags

None of these proves a contractor is dishonest, but each deserves a pointed question.

No permit

An offer to save money by skipping the permit also skips the inspection, and leaves you without the sign-off insurers and buyers ask for.

No certificate number

Vague answers about who holds the plumbing certificate, or a refusal to give a number you can check with the province.

A big deposit up front

Pressure for a large payment before work starts. In Alberta, a contractor taking deposits for home work at your door needs a prepaid contracting licence.5

A quote with no breakdown

One number with no split between plumbing, restoration, permits and GST makes comparison impossible.

A price far below the rest

Replacement firms themselves warn that unusually low quotes often mean cheaper materials or skipped steps; ask what is left out.2021

Diagnosis without looking

Some grey pipe is not poly-B. A careful firm confirms what you have before quoting.22

Pressure to sign today

Limited-time pricing or scare tactics about imminent failure are reasons to slow down, not speed up.

No written warranty

Verbal promises about workmanship are hard to enforce. Get the terms on paper.19

Are you a plumbing contractor?

If your firm replaces poly-B and wants to receive requests from homeowners in your area, contact the HAUSE desk. HAUSE does not rate, rank or badge businesses; homeowners are told to check every contractor’s certification themselves.

Questions · 5

Frequently asked questions

Does Polybutylene.ca recommend specific contractors?

No. The HAUSE desk may introduce a local contractor where one is available and you consent, but it does not rate, rank, certify or endorse businesses. Check any contractor’s credentials with the provincial body before hiring.

How do I check a plumber’s licence in Canada?

It depends on the province. Alberta has a Tradesperson Lookup Tool, Ontario has the Skilled Trades Ontario Public Register, British Columbia has a certification verification tool, and in Quebec you can check the RBQ licence and CMMTQ membership.411712

Is a Red Seal plumber better qualified?

A Red Seal endorsement means the plumber passed the interprovincial exam for the trade, which is recognized across Canada. Plumber is a Red Seal trade in all provinces and territories.17

Can I do the poly-B replacement myself?

In Calgary, owners who live in a house they own may take out a homeowner plumbing permit for work they do themselves, but not in apartment-style condos.1 Edmonton has a similar homeowner permit for owner-occupied single detached houses.2 A whole-home repipe is a large job; most owners hire a certified plumber.

What if there is no contractor available in my area?

The desk still replies with guidance. Use the vetting steps on this page to find and check a local plumber yourself, and ask at least two firms for written quotes.
