Red Seal Expert Plumber in Markham serving Toronto and the GTA

Honestly I couldn’t have had a better experience with Dima Plumbing. Andrei was honest, professional and went above and beyond for my toilet replacement. He did a great job also diagnosing whether it needed replacement or could be repaired and recommending which unit to buy.

John replaced 2 old leaky valves for an outdoor hose connection and inspected and tightened loose fittings in a kitchen sink drain. The work was completed quickly and tested to ensure all issues were resolved.

Fast, efficient and quality work for a great price. You can tell John is a master of his craft. He was polite and professional and got everything done and dusted before I knew it. Thanks, Dima Plumbing. Will definitely recommend and hire them again!

Further to a leak, had our bathtub gaskets replaced by Dima Plumbing. Prices in line with market, very professional, thorough, and polite, and didn't give up when presented with a problem and got the job done.

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!

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.

We had a kitchen sink clog that caused flooding, and I found Dima Plumbing through HomeStar based on their excellent reviews. Andrey arrived promptly with great communication and updates before his visit. He worked diligently, using several different tools to address the issue. Andrey was a pleasure to work with, and he left the workspace spotless. I highly recommend him to anyone looking for a reliable, professional plumber. His dedication to customer service is top-notch.

Called about a sewer smell problem and the person I was speaking with on the phone tried to help me over the phone . I really appreciate someone who wants to help and not trying to fleece you for as much money as they can . I would trust this company . Thanks

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.

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.

John was punctual and arrived prepared. Quality plumbing work on toilets, faucet & plumbing pipes. All repairs in timely manner. Very satisfied with work done. Definitely recommend to others requiring plumbing work.

I've used John for several jobs and found his work to be excellent, and prices to be extremely fair. Honest plumbers are hard to find. Thanks John, the world needs more plumbers like you.

Andrei has replaced our toilets, main valve and sink faucets. Always shows up on time and super helpful and professional. Always is super helpful and lets you know up front prior to doing anything major. He has had to problem solve and pivot when unexpected things have happened. Reasonable rates and will talk you through any questions. Definitely recommend Dima plumbing any day for any of your plumbing needs.

We used John recently when our kitchen sink was clogged. He was quick in responding and was very professional. Clean and also told us how to maintain it as well!Thank you John!

John is an absolute pleasure to deal with. One morning woke up to some really bad water stains on the kitchen ceiling due to some kind of leak in the bathroom above.. Reached out to John who was very attentive with excellent communication. He instructed me to take a couple photos and answer a few questions. He was able to diagnose the problem accurately and provide me with a quote for the work in a quick email exchange. He came, resolved my problem and everything was done well and completely transparent with everything.. He also took a look at another issue I had and provided great guidance there as well. I could not be more happy with the service John provided. He's a fantastic plumber and a great authentic, friendly guy. Look no further if you need a great plumbing services.
