  • We are so glad we were able to find John, he is such a professional and so friendly. We've been in our house about a year and found a leak in our ceiling directly under one of our bathrooms. John was able to find that a gasket was missing from the bathtub drain, and also the toilet gasket was replaced as there was water around it. Everything done in less than an hour. Hoping this will fix our problem, but I am confident that we won't have leaks anymore! Thanks John!

    We were very happy with the service we got from John. He was prompt in his response and came to our home quickly. He was able to resolve our plumbing issue efficiently and at a fair price. He even gave us a few hacks on how we can keep our pipes running smoothly to avoid similar issues in the future. We would definitely use him again and recommend him to our friends and family.

    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.

  • 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.

    John did 3 separate jobs around my house including adding a filter outside, fixing a pipe inside my garage, and replacing a leaky toilet shut-off valve. Very happy with the quality of the work, and John took the time to answer my questions and explain what he was doing and why. Overall very satisfied and would use him again.

    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

  • We had a problem with a leaking toilet that had to be fixed. I contacted John with my questions and received the response very promptly. After I was ready to go ahead with the repairs he was able to squeeze me into his schedule on the next day. He arrived on time and did a great job fixing the leak. It has been more than 8 months since that day and we have not had a single problem again. Another good thing that came out of his visit is that if something is going to go wrong with the plumbing in the condo I don't need to spend time searching for someone I trust with the plumbing work, I will definitely call him again.

    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

    Reliable and prompt service on multiple occasions. Installed a new sink and new toilets, fixed some indoor plumbing. Got the job done in a timely fashion with no pressure recommendations on work required and why.

  • John has done a few jobs for me over the last few years. This last job was to fix a toilet and unclog a bathroom sink. John is always a pleasure to work with and is very quick to respond, arrives on time and gets the job done. I never hesitate in recommending Dima plumbing to my family and friends.

    Needed to replace the Thermostatic valve in our shower. John Dima was on-time very professional and got to work right away. What I liked was how he worked; He put on shoe covers at the front door, was careful not to scratch or damage the shower, was constantly wiping down the surface to make sure it was clean and free of any debris. Awesome Job. I would recommend Dima Plumbing and will call upon him if we need future servicing.

    We hired Dima Plumbing to replace our outdoor faucet since it was rusty and our old hose was corroded stuck on it. John came on time, was polite and personable, very efficient with the job, and offered helpful tips on what do with outdoor faucets during the winter. The highlight for me was watching John work. It was a quick and straightforward replacement (less than 30 mins) but you could see the years of knowledge and experience with how smoothly John replaced the old faucet, cleaned away the years of rust and corrosion, and attached the brand new bib. It was like watching those mastercraftsmen working effortlessly with their tools to scrape and sculpt something from nothing. Highly recommend John and Dima Plumbing!

  • Excellent Work and Service We hired Dima Plumbing to install drainage for a new sink. John showed up on time and was very polite and professional. He took time to answer all of our questions and completed the job in no-time. He cleaned up nicely and provided helpful tips for keeping out drains clear. I would recommend Dima and John to anyone looking for plumbing repairs.

    I recently used Dima Plumbing to replace an old toilet and its shut-off valve. I highly recommend their services. John's quote was reasonable compared other plumber's quotes I received. He was very prompt in everything - replying to my request for a quote, answering my questions, booking an appointment, and arriving for the work. He did the job efficiently, following COVID guidelines, and explained well what needed to be done. If I need future plumbing work, I will contact Dima Plumbing and will recommend this plumbing firm to my friends and family.

    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.

    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.
