More Than 40 Years Of Combined Experience

"We do not want you to worry about a growing repair bill. We provide only upfront rates and stick to it."

DIMA PLUMBING is led by a licensed Red Seal Master Plumber and OWWA Backflow Preventer, bringing more than 40 years of combined plumbing experience, bonded, and insured.

After working for a big plumbing company, one of the leading plumbing companies in Toronto, I’ve decided to run my own plumbing business to offer the same high quality of service at a more affordable price.

Since every situation different, I provide a variety of plumbing services, tailored for your specific need and budget: new installations, repairs, or replacements of any kind. Your business and time are valued and you will be as informed as possible as per your options before any work is done. Estimates are free of charge.

"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."

"I needed my hot water tank mixing valve switched according to my water heater renter. I texted John after finding him on Google and he gave me a quote. John came the following morning and resolved it. No problems whatsoever."
