Red Seal Expert Plumber in Markham serving Toronto and the GTA

John's (Dima Plumbing) work is perfection and did exceed my expectation within a fair price. He is kind and professional. Highly recommend for any issue.

Great Plumbing Company . Not the cheapest but they do a great job at a very fair rate ! Very professional and busy at times

I initially thought I needed a complete faucet change but after review, John mentioned I required a new cartridge which was not as expensive as initially quoted. I booked John for his honesty and integrity as I sent the same details to several other companies who quoted $800-$1200. John came within a 24 hour turn around time and fixed the leak in my faucet! Thank you again

We had a leak in a basement ceiling pipe and needed a plumber quickly. Andre came the same day and even though it was quite late for him and we were his last job on a Friday, he was just so pleasant and lovely. And he did an amazing job. Very reasonably priced. 5 stars PLUS! Top notch business.

It was our first time with Dima Plumbing and we’re very happy with their work! Faucet shutoff valve was stuck and Andrei squeezed us into his schedule. He also repaired the sink drain, and explained everything patiently. Very courteous, quick response, quality work, and reasonable pricing. Will call them back for any other plumbing issues.

I’d used John’s service twice within last several months. First to replace the basket strainers with the kitchen sink, he also replaced the piping without charging extra when he saw the pipes not installed properly from before. Second time was to repair a leaking toilet. John was able to identify the issue when I explained to him on the phone and he came and fixed it. He also fixed other issue on the day he visited and the charges are reasonable. Will definitely use the again

My call was courteously taken and John arrived on time. He quickly checked the issue with leak and then replaced the kitchen faucet quickly. He also worked on to unclog the pipe and all finished in a couple of hours. Very professional and good quality work. Will definitely call him the next time.

Perfect! Been one week since drain, filter, and insinkerator installation.Appreciated advice on Insinkerator- bought the unit on John's advice and can't be more happy with the product.Thank you for advice! High quality workmanship - John leaves you with confidence.I found my plumber to go to.Highly recommend.5 Stars hands down...Alex.

My main shut off valve was experiencing a slow drip due to its age (almost 40 year old house). First, John was very prompt in providing me with a quote. When I decided to go with Dima Plumbing, John told me how I needed to co-ordinate with the city for the water shut off and told me the day he was available. On the day of the installation the city inspector was delayed all morning. Once he arrived, I texted John and he quickly made his way down within 30 minutes. He asked the inspector to stay while he installed a new ball main shutoff valve. John was done within 15 minutes thus saving me the cost of turning the water back on later in the day. Watching John work, I could tell he had a lot of experience and knew his stuff. Overall, he was very pleasant to deal with and I recommend him to anyone requiring plumbing services. You are not going to be disappointed.

The wall behind my toliet was making a loud noise whenever I flushed so I found John on the internet with good reviews. John answered his phone quickly and an appointment was scheduled for the next morning. John was very prompt and efficient and replaced the valve in my toilet in 30 mins. John is also pleasant and very professional to deal with.

These are real honest professionals who stand by their work. They are highly skilled, knowledgeable, and, best of all, provide a high level of customer service that's rare to see these days. I highly recommend them.

Top notch work from John! Called and asked about the issues we were having, John came the following day. Followed all Covid-19 protocols, set up shop, ensured everything would be left tidy and clean. John made some recommendations on things to do, which was greatly appreciated. John cleaned up, answered some general maintenance questions I had and was in and out in about an hour. I couldn't and wouldn't recommend anyone else! Thank you John!

Reached out to Dima Plumbing based on the overwhelming positive reviews on Homestars. Was contacted promptly by Andrei, I provided a few pictures and description of what I wanted and he was very upfront with the solution and pricing. Andrei arrived exactly when he said he would and did an amazing job installing drain baskets and piping for a new kitchen sink and copper water line to our new fridge. The work was done quickly and the quality of the install was excellent. Andrei was very pleasant to chat with throughout the entire process and I would absolutely work with him again!

A great company with real professionals and affordable prices. Andrei diagnosed, explained and eliminated two problems for us - with a stink in the laundry room due to an incorrect connection of the washing machine, and with a leaky bath tub. He was extremely polite and patient during the conversation, came on time, proposed the least intrusive solutions, and was very attentive, careful and clean in his work. Thanks a lot, Andrei — amazing job! 👍

We use Dima Plumbing for ALL our plumbing needs. They have always provided a smooth, efficient, and professional service. Our most recent call to Dima Plumbing was for a toilet shut-off valve leak; Andrei fixed the leak the same day. One of the best examples of service occurred during our recent kitchen renovation. Dima Plumbing provided consulting advice prior to our purchase on a new undermount sink. Once the renovation began, Dima Plumbing was first on the scene to cap off the drain (allowing the installers unhindered access for cabinet installation) and was last on the scene to reconnect the sink and the dishwasher back to the drain. HIGHLY RECOMMENDED plumbing service! Thank you Andrei and Dima Plumbing!
