- Simon Leung4.0Flow is the way to go. While undergoing some renovations in my newly acquired century home, I have needed the services of plumbers a few times. I have learned that some plumbers are there to drain you of your money; some plumbers charge a lot more than others because they are a big company with big overhead; there are plumbers who will do 'this' but not 'that'; the are plumbers that seek to soak you; and then there are the ones whom we hope to be the 'good ones' who explain what they do, charge you a fair price and become your trusted trade. Flow appears to fall under the last group. Admittedly, the job was a very small one of attaching a line off the hot water to supply the furnace humidifier. Nonetheless, I felt very comfortable with my plumber and hope that they will be my go-to from now on. My one suggestion for my scenario is that the furnace humidifier filter have been checked before we let the water run, as apparently (I didn't see it but my contractor said it was the following day) my filter was well past it's end of life and the water ended up overflowing the system. Once I replaced the filter it all worked as expected. The filter may not be in scope of the plumber's work but since it is connected, I thought they may know something about it and could point it out as something to check. Happy to supprt a local, independent business. Happy to use them again and recommend to my neighbours.February 2026Google
- Melanie Kok Jager5.0We’ve been having persistent water flow issues at our house and the guys from Flow responded immediately to stop by the next business day. They were super professional and found the issue. Highly recommendJanuary 2026Google
- Laurie Nielsen5.0Just had Peter and Garrison here to clean out a blocked sewer line. This is the second time Flow Plumbing has been here, with Peter clearing out a different part of the sewer line. Excellent service both times. Very knowledgeable and I was given advice on moving forward to make this process even easier. They will be back to make necessary changes in this old house. Highly recommend!!December 2025Google

About Flow Plumbing
Flow Plumbing is a family-run Hamilton company at 36 Albert Street, in the city's east end. Google shows 60 reviews at a perfect 5.0 average, read September 24, 2026, and lists it as open 24 hours.
Its website says Flow's team is made of trained, licensed professionals who work to the Ontario Building Code on everything from small repairs to large remodels. The service list covers residential and commercial plumbing, installation and repair, custom homes, additions and renovations, and 24/7 service. Its photos show walk-in showers, freestanding tubs, rough-in water lines and sewer lateral replacement. Flow also encourages owners of homes with lead water service lines to replace them, which matters in Hamilton's older neighbourhoods. Estimates are free and flexible according to materials and scheduling. Flow is a member of the Hamilton-Halton Construction Association.
The reviews suggest a company that customers keep calling back. Jessica said Flow did her entire downstairs renovation, snakes her pipes twice a year and handles anything that comes up in her older home, and called the pricing very reasonable. Simon, renovating a century home, gave four stars and said Flow falls into the group of plumbers who explain their work, charge a fair price and become your trusted trade. Gina had a kitchen faucet supplied and installed and said the crew arrived when promised. Matt, who has worked alongside Flow on several projects, said they lift the mood on site.
The website is thin. It does not name the owners, give a founding year, list a warranty or publish an email address, and the contact form is the main way in besides the phone.
Flow suits a Hamilton homeowner with an older house who is planning a bathroom, basement or addition, or who wants a lead water service replaced. It suits less well someone who wants written warranty terms before calling. Ask for warranty terms, confirm the plumber's Ontario certificate of qualification, and ask whether any City of Hamilton lead pipe program applies to your home.
