Red Seal Expert Plumber in Markham serving Toronto and the GTA

Appreciated John's prompt responses, timely and professional service, and advice on how to maintain the kitchen drains. Thank you!

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.

John was fantastic. Very Covid friendly, courteous, quickly responds to email/contacts. Did a great job fixing our issues and did so in a timely manner, very clean workplace and left the area spotless. Couldn't ask for more, will definitely use again. Don

Andrei Dima of Dima Plumbing is very professional, skillful, courteous, patient, and has the best customer service I have seen. He works wonderfully with his father, John Dima, in their trade business. Last Thursday night, I had a very stubborn kitchen sink clog, and Andrei came to the rescue just 4 hours after I called him on Friday morning. He was very honest about the work, and the phone estimate was very accurate. There was some complication with the clog, leading the snake to go up the vent rather than going down the pipe where the clog was. Andrei recognized the problem and patiently re-snaked the pipe to clear the clog. He explained what was going on every step of the way and shared his train of thought with me, which I appreciate. In addition, he was very careful and patient with my existing pipe when opening it up to avoid any cracks. He also helped me clear up my under-the-sink cabinet before his work and cleaned up any mess afterwards. I am very impressed. After the repair, Andrei showed me some tips on maintaining the kitchen sink to reduce the chances of it clogging up again in the future. I am very appreciative of his initiatives. What differentiates Andrei from others is that he is very professional, enthusiastic and takes pride in doing his job, in addition to his honest and friendly personality. I will definitely use him again if needed and highly recommend him to anyone in need of his service.

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.

I contacted John for a shutoff valve and outdoor faucet that needed replacing. He arrived at my house 30 mins after I called and he had everything done in about an hour and a half. Our shutoff valve is boxed in with drywall and accessed through a little door. Another plumber that I had contacted first, but didn’t use, was adamant that he would need to cut out the drywall box. John made a point of trying to avoid any damage and, in the end, was able to finish without cutting the drywall, which I really appreciate! John was very professional and courteous and his price was very fair. I’ll definitely be contacting him again for future plumbing jobs.

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.

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.

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.

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!

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.

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.

John was very quick to respond to my inquiry, call him in the morning and arrived the same afternoon. Had him inspect my toilet flange after i had renovated the flooring. He was in an out in a matter of 30 mins. Will definitely call him again!

Had a clogged sink and they arrived within 24 hrs. They fixed the problem quickly, took the time to clearly explain how to prevent these clogs from happening in the future and were reasonably priced. I would definitely use them again.
