A To Z Plumbing & Drain
We are certified plumbers, licensed by Toronto municipal Licensing & Standards department. We specialize in complex jobs, backwater valve and sump pump installations, drain repairs, and basement waterproofing. We stand out among hundreds of Toronto certified plumbers by giving you our unconditional guarantee.

Recent Review: Dmitry and crew are always on time. Clean installation that required a bit of a creative thinking because of the position of the backwater valve. Dmitry was like surgeon, exploring where exactly drain pipe is and cutting precisely where needed. Paperwork was taken care of. Why choose a certified Toronto plumber when dealing with plumbing emergencies?

Handymen without a license haven't studied specifics of Toronto's plumbing, drainage, venting and sewage systems. They may harm your home or plainly not finish the job. You will not get rebates from the city unless your plumber is certified. We see it every day. We are on call 24x7, ready to do sewage clean out and get rid of sewer smell in your house.

This was my first time I had to deal with water leakage and kitchen faucet replacement and after multiple searches I was able to get in contact with Dmitry. He was very quick and efficient with the work and he was very kind as well. I would definitely stay with A to Z plumbing & drain for any future services. Thank you greatly Dmitry for your work!

My bath tub was leaking in an almost impossible to reach spot. I had a first plumber come in, quote me over $1000 and telling me they would have to cut up the ceiling below, I'd have to go through insurance and so. Dmitry came in and was able to get the job done without cutting up the ceiling for less than $800. Would recommend this plumber to anyone in the area.

We had a french drain installed by AtoZ. The work was done quickly and efficiently. Took ~four hours start to finish, including clean up and taking away the excess soil. Its a rainy day today and everything seems to be draining nicely! AtoZ also installed a couple of bathroom sinks for us on the same day which is much appreciated. Owner Dimitry is a good man to do business with.

We had a sump pump and backwater valve installed. I had called a few companies and actually had someone from a certain popular home renovation app who was supposed to complete the work - however, they said I had to remove a bunch of existing shelving in the area and get the concrete poured myself after to cover the hole in the ground. I am so glad I didn’t go with them! I called and reached Dmitry right away and he answered all my questions. He came the same day and gave me a quote which was very reasonable. Once we agreed, the job was completed within a few days including the city inspection

Dmitri came to unplug the basement toilet on June 11/19. I was impressed with the questions he asked in advance so he was familiar. Once he completed his work, he was able to assure me that the drain and the toilet were okay, but that there were 3 steps to be followed to be sure the toilet did not clog. During the service call the tenant who occupies the basement unit was extremely rude & derisive. This did not faze Dmitri. This very bad patch with my tenant is over and he is now following the plumber's instructions. The toilet has worked very well for several weeks & I expect that to last as we

We had a very pleasant experience working with Dmitry. Not only was the completed job up to our satisfaction but we were also really pleased by how Dmitry and his crew went about doing the job. They were very clean, courteous, and professional throughout the work. Dmitry is also really diligent with communicating with his clients. He was really prompt in his responses to our slew of questions and made us feel like a valuable customer. I have no reservation whatsoever in recommending AtoZ plumbing to others. I sure will be relying on them for future plumbing work.Great job once again, team!

We are very happy with the work completed by Dmitry and his team. First, Dmitry went above and beyond by visiting our home to provide a quote on the day that we called since he happened to be nearby. We had a sump pump and backwater valve installed in our older home in East York, as well as having some older pipes replaced and plumbing for a laundry sink added in the basement. All the work was completed efficiently, with very good attention to detail, and for a reasonable price. All work areas were left neat and tidy. Dmitry is also knowledgeable about the requirements for the City of Toronto Basement

The person we bought the house from had supposedly installed new drains but if they did, they were installed incorrectly. The only used 1 1/2" pipe so the drain kept backing up. Dmetri came by, assessed the problem and we agreed to a price. We needed to replace the drain with a proper 4" drain. He and his crew were on time, completed the work correctly and quickly, cleaned up after themselves. I am very happy with the job and would recommend him to anyone.

I am absolutely 100% satisfied with this Company. Even though it was the very first time I called, Dimitry quickly responded to my call and was available to rectify the problem the same day. Not only did he deal with me, but he was willing to contact my tenant and see what time was good for her.
Once the work was done, I immediately received the invoice by email. Surprise....it was reasonable and no excess charges!!
I would definitely recommend Dimitry and his company and I would not hesitate to use him again.

Dmitri and his team were very professional, friendly and took care of all my plumbing needs. I would definitely recommend A to Z Plumbing to anyone that is in need of quality work done right, on time and at a fair price! Thanks again Dmitri!
