Sean and Travis were outstanding! Professional, punctual and efficient! HIGHLY recommended them for ALL your plumbing needs! (Plus they are cuties; just sayin 😉)

Amanda Crowther

Sean O'Connor provided a 5 star service for my mom's kitchen plumbing issue. Top notch customer service, honesty, quality workmanship and timely service. I'd give him 6 stars if it was an option.

George Coffin

Didn't show up. Didn't call.. After I called said he would be here after lunch. Didn't show up and didn't call. You indicated you called to confirm the appointment but no answer..you told me on the phone you would be here after lunch when you failed to show it or call in the morning.

Before you hire a plumber in Ontario

Yes. Plumber (306A) is a compulsory trade in Ontario - working without certification is illegal, not just inadvisable.

Certificate of Qualification, 306A Plumber

The individual doing the work must hold this, or be a registered apprentice working under someone who does. Ask for the certificate number and the name it is issued to. It belongs to a person, not a company.

Verify with: Skilled Trades Ontario maintains the public register of certified tradespeople.

General liability insurance

Two million dollars is the common floor for residential work. Water damage escalates fast, and a burst supply line during a renovation can exceed a small policy in an afternoon.

WSIB clearance

If a worker is injured on your property and the contractor has no coverage, you can be drawn into the claim. A clearance certificate is free for the contractor to pull and takes minutes.

Verify with: WSIB issues clearance certificates directly to the contractor on request.

TSSA gas technician certificate (only if gas is involved)

G1, G2 or G3 depending on scope. Required for anything connecting to a natural gas or propane line.

Verify with: The Technical Standards and Safety Authority regulates fuel safety in Ontario.

Questions worth asking

  • Is the person doing the work certified in 306A, or an apprentice being supervised? Both are fine. You just want to know.
  • Is this quote flat rate or time and materials? If hourly, what is the estimated range and what happens if it runs over?
  • Does the job touch a gas line, and if so who holds the TSSA certificate?
  • Does this need a municipal plumbing permit, and are you pulling it?
  • What is the warranty on labour, separately from the manufacturer warranty on parts?
