JP B1.0DO NOT USE THIS COMPANY!! I am sick to my stomach that they came in, over priced a quote for basic work, and then when I declined charged me $90 for showing up. I feel like I've been robbed my money. This is not how you do business. They quoted me $300 for a basic fridge water line repair, and $900 for better thicker waterline.August 2026Google
Kevin Sullivan4.0They were there quick. Job was done same day. Cost way too much but that’s life I guess. I could have just installed a $200 toilet myself but then I woulda had to shop around and not be sure I got what I needed. Sure watching YouTube and being capable was an option but when it’s like okay do I pay the 90$ for them to just tell me what I need? Or do I just say well you got me over barrel just do it? So I chose the ladder. Now I get to write a review. Remember you asked me to write it. Yay! The work was good, cost more than 3x what it woulda cost to do it myself but it is what it is right! 😘August 2026Google

About John The Plumber

John The Plumber is a plumbing and drain company with a Hamilton branch listed at 38 Gledhill Crescent on the west Mountain. Google shows 527 reviews at a 4.7 average, read September 24, 2026, and lists the location as open 24 hours.

The company's story starts with its founder. The website says that back when John was a plumber, before the business carried his name, he saw how some tradespeople were treating customers and set out to do it differently. It says Hamilton customers have been coming back since 2006. The plumbers are licensed and insured, and the company offers same-day service in and near Hamilton.

The work splits into two halves. On the plumbing side there are water heater repair and installation, faucets and sinks, toilets, dishwashers, outdoor faucets, sump pumps, pipe repairs and backflow prevention. On the drain side there are emergency drain cleaning, camera inspections, hydro jetting, sewer line cleaning and sewer line replacement. Every job carries a 2-year plumbing warranty, which the website calls the longest in Hamilton.

Reviewers name Andrew more than anyone. Hilary had a leak over a long weekend and said Andrew came out on a holiday Monday after a scheduling hiccup and had the water back on quickly. Valerie said he fixed a seized outdoor faucet in no time. Kendyl had been quoted more than $1,800 by another company to fix the piping under a double sink, got a same-day visit, and said Colin quoted exactly what was expected and the repair took about 20 minutes. Catherine credited Andrew and his crew with digging a long trench around a large tree to recover an engagement ring from the sewer line. Kevin gave four stars and said the work was good but the bill for a toilet swap cost far more than doing it himself.

John The Plumber suits a Hamilton homeowner who wants a quick visit and a written warranty that runs longer than most. It suits less well someone shopping hard on price for a small fixture swap. Ask for the quote before work starts, confirm the plumber's Ontario certificate of qualification, and check who takes out the City of Hamilton plumbing permit when one is needed.
