    Repair or maintain boiler-
    Boiler system was red-tagged by Enercare. Enercare were unable to assist with addressing the problem they had caused (strange and definitely not what their advertising says). Tenants were cold. Marnie and her people at Convertible did a great job getting people on-site right away, removing the old boiler, and getting a new combo boiler/hotwater tank system installed so that the heat and hot water were restored and the tenants able to live comfortably again. I would highly recommend Convertible (and would 100% not recommend Enercare !)

  • Should'a Got Us

    HVAC contractor in Newmarket
    • Best of the Best 2022
    • Best of Awards 2022

    SHOULD'A GOT US is a new company by name only. However, the company has well over 15 years of experience and knowledge. SHOULD’A GOT US was aptly named by our own clients and their neighbours who would stop by at various job sites and compliment us about our workmanship. Then, they would comment on their own past work experiences with which they were not completely satisfied. In response, we simply said: You SHOULD’A GOT US! We at SHOULD'A GOT US, take great pride in our work from the beginning of each and every project from start to finish and we strive to complete the jobs on time and when possible below budget. Please take the time to research our work, look at our gallery of photos, and to read the comments of our satisfied clients. References will gladly be furnished on request. Thank you, Larry Rudd

    We just bought a home and we wanted to put in a fence. This company came highly recommended by homestars and they did not disappoint. Larry is very professional and respectful giving us excellent advice on how to approach our fence. We had something in mind and he outdid himself. The fence is very sturdy and beautiful, and the deck looks brand new! We couldn't have asked for a better contractor, and whenever we have more work to do down the line, he will be the first we contact.

    Mark was on time, polite and professional. The furnace maintenance work was performed quickly and efficiently. He effectively problem solved and diagnosed the pilot light issue with the gas fireplace (the main reason for the service call) and fixed it. He also cleaned everything - it looks and operates like new :) This service call far exceeded my expectations - very satisfied!! Thanks Mark :)

    Things I liked: - Ali was polite and friendly and a pleasure to talk to. - Quick price over the phone, no site visit required for a simple job - He said availability was any time with a couple day's notice, and he came through on that. Honoring your word is important - the job got done quickly and with no problems Things that were less than perfect: - he had 2 assistants which made the house a bit crowded for such a small job - after the job was done he didn't light the pilot light on my water heater - he didn't supply a flex hose for the final connection to the gas stove. Once he saw the used stove that I bought, he asked if it came with a flex hose and was apparently surprised that I didn't have one. Apparently he doesn't carry extras on the truck so I had to go and buy one. A google search of "do new gas stoves come with flex pipe?" reinforces my suspicion that it was probably just his way of getting an extra 50 bucks on the job I am easy-going so I would recommend him just based on good availability and coming on the day we agreed to, that is more than you can say for a lot of contractors. That is why I overlooked the other issues. But some homeowners could be much more upset by the other issues.

    This job required a full demolition and installation of a walk in bathtub, a new window, wall and ceiling tile, repairs and refreshment to the remaining drywall area and installation of a pocket door. The job required the involvement of several tradesmen. All of the guys were great. They obviously knew what they were doing, worked quickly with minimal intrusion on us. they were friendly and willing to answer any questions or concerns. they made a minimum of dirt and dust and cleaned up very well every day. the job was completed on time and on budget and we love it.

    Grande Tile and Reno Plus renovated our two bathrooms, built a master bedroom closet, painted bedrooms and removed the stippled ceiling in our bedroom. Howard was amazing at guiding us through the process and assisted us to choose complimentary colours for our tile and grout! John is an awesome tile setter. He is an expert at his trade and very respectful! Nick did an exceptional job of our master bedroom closet with beautifully hung doors! Nick is an expert carpenter-electrician/plumber. Ming is a fastidious painter and expertly repaired the damaged drywall areas. By the end we were ready for the project to be finished. There were some minor adjustments and Howard does make sure there is ongoing customer satisfaction which is to be commended Thank you Chris and Dave

    Great service—fast, professional, and friendly! My old AC unit stopped working in the middle of a hot day, and Morteza had it back up and running the same day.

    We were very happy with the service received from T.H. Oliver with our 16 year old water heater. Darren and Terry replaced the water heater in a morning. Very professional, office staff were great, answered any questions and Terry came back on Sunday to make sure the heater was working. Have used T.H. Oliver in the past for our furnace.
