I called Drain King Plumbers in a panic after my sink had collapsed, which is something I had never seen or even heard of before. It's safe to say that they were the absolute best and I would recommend Drain King Plumbers to anyone and everyone I know. First off, the customer service is amazing- a lovely girl named Rachel picked up and explained everything I need to me. She connected me with an awesome worker named Alberto who was just as amazing. Alberto got to my unit within an hour after the call was made and the fix was seamlessly done. The sink collapse was a shame and was something that should have never happened but I met some great people through the incident. There have been no issues and everything has been working great. Would 10/10 recommend!

Drain King Plumbers. I had a problem with my toilet backing up and decided to call Drain King plumbers. I have yet to experience service standards set by this company and their technician Jonathan. His exemplary service and advice were very well received by myself. He spent almost an hour trying to determine where the problem was and advised me to call the region of Peel as it appeared the problem was on the municipal side. Jonathan could have easily taken advantage of the situation and charged me for the time he spent on my property. My hast off to you Jonathan and to your company for having personal like you working for them. I highly recommend the services of Drain King plumbers and will surely use their services if ever a need arises. Thank you very much to all of you and Drain King plumbers.

Your employee uncloged the drain using the "snake". He tried to untighten a nut for making room for the snake. He could not untighten the nut neither by hand nor using the pliers. He banged in the connection hoping to succeed. It did not work and then he cut the long drain pipe. He succefuly uncloged the drain. He connected the cut drain pipe using the rubber connector, he reconnected everthing back as seen in the attached picture.For the moment everything was working, but next morning under the sink I found a lot of water. I called Drain King and I was connected with your employee I asked him to come and take a look and see what the problem might be and fix it. He kept me a lecture about what might be and refused to come and fix the issue.Now I have to call another plumber to fix the problem. I am sorry, but this is not a professional aproach by Drain King. For this reason I cannot give more than 2 stars.

I rarely leave reviews, but this experience has been extremely frustrating and costly. I contacted this company for a recurring basement drain backup. After multiple visits, I was given different explanations each time, and each visit resulted in additional recommendations and charges, without a lasting fix. I was first told the T-connection was the issue, which I replaced at my own expense. That did not resolve the problem. I was then told the kitchen and basement lines required flushing/hydro jetting. A technician later suggested completing the hydro jet privately for cash, which I declined. I paid the company directly for the hydro jet service instead. When the technician returned, he initially refused to hydro jet the kitchen. After I insisted that the paid service be completed, the work appeared rushed and very brief. Three days later, the kitchen sink backed up again. Another technician advised that the kitchen line was still full of grease and required proper hydro jetting, indicating the previously paid service was not completed as invoiced. Since November 6, 2025, I have repeatedly tried to resolve this with the office. Promised callbacks never happened, calls are no longer being answered, and as of January 22, 2026, my kitchen remains unusable. Based on my experience, I would caution others to be very careful and to get clear documentation of what work is actually being performed.

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?
