Red Seal Expert Plumber in Markham serving Toronto and the GTA

We had a clogged sink in the kitchen that they quickly resolved. Same day service with preventative tips. Andrei was very nice and professional. Definitely recommend and will be calling again if we have any issues.

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!

I initially contacted Dima Plumbing based on the great reviews on Homestars. I had two small projects and John did a great job each time. First I had to change a tap in the backyard which bursted during winter. John responded promptly to my message and came the next day doing the job quickly and professional. Based on this experience I contacted him again when my kitchen sink got clogged and I got the same professional service. I would definitely recommend Dima Plumbing.

Searched all around for somebody to help me figure out how to descale my tankless water heater. I called many plumbers and got outrageous quotes for what I thought should be a small job. Fortunately I got in contact with these guys and Andrei went above and beyond helping me out. Highly recommended

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.

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.

Dima Plumbing replaced 2 outdoor and 2 indoor faucets for us. Andrei was always very prompt to respond to any questions we had beforehand, and was always very courteous throughout the whole process. His workmanship was excellent, and we had no issues. We would definitely use him again for our next plumbing project!

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.

Andrei rocks! Provided incredibly great customer service, value and responsiveness. Installed two faucets, hooked up a vanity sink, rebuilt both vanity plumbing and fixed an ongoing issue with toilet water supply. For the whole process explained what was required and why - was total confident in the job! Wish there was a six star review. Totally recommend Dima Plumbing. So glad to find my 'go to' plumbing trades person. Thank you so much!

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.

Incredible service! +++ So glad to have found John, as now our go to master plumber. He is very professional, reasonably priced, highly skilled and a true gentleman. Getting an accurate quote from John was quick and easy - I submitted pictures with my job list using their web form, received a fair quote within the hour, and a few minutes later I was able to book a convenient time with him. He came on time and communicated 30 minutes on the dot before arrival. He installed a handheld bidet sprayer with hot and cold water connection and a pair of water hammer arrestors for my front loading high efficiency washer. He worked clean and efficiently and checked everything with me before wrapping up. Highly recommend him and will be calling him for all my plumbing needs going forward.

I contacted John (Dima Plumbing) to repair a broken copper pipe to my refrigerator ice maker; and to repair the main floor toilet. I found John to be very polite, professional, and knowledgeable. I am completely satisfied with the work done by John; and I will be contacting him for any future plumbing needs. Keep up the great work, John (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.

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 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.
