I am relatively new to Pickering and did not know of any reliable local plumbers. The toilet in our master bathroom had a small leak at the base and it was beginning to affect the floor tiles. I did research on Homestars, read all the reviews and selected John Dima to do the repair. He came to our home on Feb. 29, 2016 and fixed the problem by installing a new toilet seal, caulking around the base of the toilet and changing the bolts on this heavy American Standard toilet, as they were insufficient for its weight. John was very professional, polite and showed me the work he had done each step of the way. While this was a small job, John gave it as much attention as if it were a large job. I waited 2 weeks to write this review because I wanted to make sure there were no subsequent problems with the toilet. To date, everything is working perfectly and no more leak! Thank you John. I will call you in the future for any plumbing issues we may have.
