It’s nice to be able to post a good review of a tradesperson for a change, after my many negative experiences during my renovation-from-hell in 2014 to 2015, some reviews which I posted on this site previously. (By the way, there are other reviews on this site for both "High Park Plumbing " and “A M High Park Plumbing,” as the latter is a name left over from the days when trades wanted the initial A in front of their firm’s name so they came up sooner in the old printed Yellow Pages listings.)
I had used Mark from High Park Plumbing about a dozen years ago and was very pleased with his work at that time; one plumber then had wanted $100 just to walk through my front door, and another had wanted more than $1200, because he claimed that the plumbing repairs could only be done by demolishing a nearby wall to access the pipes, whereas Mark had accomplished the work for only $200 without demolition and had done a conscientious and careful job. So I contacted him again when it turned out that my contractor-from-hell 2014 to 2015 had botched the drains in my basement, so I had a constant stench coming from the floor drain in the laundry room. I got opinions from two separate plumbers, one of them Mark, and both agreed that the floor drains had not been done according to code, so that sewage was back-washing from the ground floor toilet waste stack into the laundry room drain, hence the constant smell. I decided to move forward with Mark, because I had used him before.
Mark always returned my phone calls and arrived promptly (although his workers occasionally were delayed), did a careful assessment, and gave me a detailed diagnosis and estimate. He and his workers (Bob/Bogie, who has been working with him for 27 years, and his nephew Michael, as well as an experienced tile setter Ziggy) did an excellent job. They had to dig up much of the laundry room floor (granite tiles, concrete, gravel and soil, etc.), replace the faulty drain-work, re-do the floor, and re-stack the washer and dryer. Everyone was pleasant and conscientious, the work was accomplished in the expected time frame, and now there is no more embarrassing and unhealthy sewage gas and stench in my house! (I’m giving them 9 rather than 10 stars because there was a lot more dust everywhere than I had been warned about, and although Mark and his crew did a pretty good deal of cleanup, there was still quite a bit of dust left over for myself to dispose of, which was a bit tedious; I would have stuffed rags under all the doors and put plastic over everything if I had been warned.) However, I would certainly use Mark again, and I recommend him to anyone who wants a plumber with old-fashioned European values of a good work ethic, value for the money, and honesty.
