General contractor service- 28 Sep 2025
I got help from Mercuri Renos for the caulking of the exterior section of my large double door. Natale was punctual, courteous and efficient. He used a water resistant material to ensure the best results. He even squeezed in my job so that my door would be done before the incoming rainy days. His rate is also competitive. I would recommend his company to my relatives and friends. Many thanks for your great service!

DO NOT HIRE AMIR - THERE ARE HUNDREDS OF OTHER OPTIONS Amir M. installed a new gas water heater in my residence last year. Enbridge did an inspection on the house due to an unrelated service call. They flagged Amir’s work and tagged the gas line with a WARNING TICKET and gave us 45 days to fix the problem. Amir connected the gas line to the furnace line. That is not to code. I immediately contacted Amir. He kept saying he will come…gave me the run around for weeks and did not show up. If my gas is not fixed in the next week Enbridge is going to shut off the gas!!!! I am in the process of hiring another licensed tech to do the work. I feel upset that Amir did not do a proper install and cut corners. But I am more upset that he has given me the run around and not stood behind his work. We all make mistakes but we must be held accountable if we are not prepared to fix them.

John was very genuine, knowledgeable and offered very competitive pricing. I know some contractors can be headaches but he was a pleasure to deal with and we couldnt be happier with the end result. We had all of our old patio pavers removed around the house/into the backyard and replaced with white concrete. We were shocked with how efficient John and his team were to get this project done. We have cameras all over our house and while I was at work I would check in to see the progress. The demolition was extremely quick and they were also mindful of neighbouring houses. Most importantly, the concrete looks amazing and we wouldnt hesitate to use John/Concrete One again or recommend to a friend/family member. You cant go wrong - highly recommend!

NOTE: the amount cited above includes the cost of fixtures that we purchased from the fixture suppliers. It has been a year since we remodeled our bathroom with the help of K-Wood Kitchens. We love it as much now as on the first day of completion! When we decided that the main bathroom in our 1960s era house needed an upgrade, we consulted with neighbours who had had renovations done in their similar houses. This enquiry produced a short list of two suppliers, one of which was K-Wood Kitchens. We viewed the work that each supplier had done in our neighbours homes. Both were excellent, so we requested quotes from each. K-Woods quote was substantially more expensive, but the consultative offering that included 3D computer modelling to help us visualize our ideas more than made up the difference. In retrospect, now that we know how many decisions had to be made to produce the final result, we realize how lucky we were to have chosen K-Wood. K-Woods advisor Endrina accompanied us diligently along the decision path, sometimes providing samples herself and sometimes hooking us up with external partners to help us find the right fittings and fixtures. We are glad that we chose K-Wood Kitchens for our bathroom renovations and, should we have need for future renovations in our home, we would not hesitate to hire them again.

Install or renovate bathroom- 29 Jan 2026
Shiraz Pro (Sam and his team) did such a wonderful job on our bathroom, we asked him to stay and rebuild our kitchen from the studs up. Sam paid attention to every detail, supported our choices, and built us a space that is unique, full of life and character and perfectly executed. Sam is a master with carpentry and a million other construction tasks - he never ceased to surprise us with how much he could handle (even when our century home threw curveball after curveball).

Install or repair faucets- 16 Jun 2025
Job went well. Canadian Rooter was very professional, prompt and appeared reasonable. Repair was completed on May 27,2024. "The wax ring was slit. replaced with new wax ring tested before leaving and works no more leak" Unfortunately, I am having the same issue 1 year later. Repair appears to have been a temporizing measure and am seeking further assistance currently at solving this as of June 2025.
