Excellent Service and Professional Work! I had a great experience with A.D Plumbing here in Ingersoll. They were quick to respond, friendly, and very professional from start to finish. The plumber arrived on time, explained everything clearly, and did top-quality work at a fair price. It’s hard to find tradespeople who are this reliable and take real pride in their work — A.D Plumbing definitely stands out. I’d highly recommend them to anyone in the area needing plumbing repairs or installations. Great local company with honest, skilled people!

I cannot say enough good things about Adam and his team at AD Plumbing. They have done many repairs in my home, and most recently, fully plumbed in and completed my bathroom in an addition I built into my home. Fast, clean, and fair priced. No issues passing inspection either. If you need a plumber, Adam is your guy.

Very proffesional plumbers Adam and Eric.True to there quote. I recently had my bathroom redone lots of questions were asked and answered, as they were very approachable compared to grumy others. I have had in the past as if they didn't want to be there dont bug me. I trust them in my home completely.They got the job done ,cleaned up after themselves as if they weren't there. I recommend them as they deserve a 5 star. Well done.They will be back for sure. They also do great handyman work to finish off the appearance surrounding the job done.

Excellent service. I've had A.D. plumbing out a few times to fix plumbing issues and install new plumbing for a powder room. They were professional and thorough; provided advice on the best options for what would work in our powder room. Very happy with the work. Would highly recommend and will be using them again in the future.

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?
