    Courteous, knowledgeable, helpful, thorough, friendly, punctual and professional is how I would describe Trevor, the principal of Toronto Drains & Waterproofing, and those who work with him. It was only by reading the excellent reviews on HomeStars that I found this company and I am so happy that I did. Toronto Drains & Waterproofing has a "Code of Ethics" printed on its website and, in its dealings with me, the company did as it promised it would--in all respects. The work done for me included the clearing of a blocked drain, the replacement of a broken drain and the replacement of some piping and taps: drain AND plumbing work. Highly recommended.

    Working with Hi-Lite Electric was a great experience. They were skilled problem solvers and I really appreciated their willingness to explain the work they were doing. They upgraded my service to 200AMP, ran new circuits for a dryer and dishwasher, and installed a new bathroom fan. Throughout the process, they were communicative and always showed up on schedule.

    The experience we had was absolutely terrible! We DO NOT recommend this company. We've spent over $50,000 and still have an incomplete kitchen. We told Dan at Caledon Renovations, from the very beginning, that we needed the renovation completed as quickly as possible to sell and relocate for work. Dan told us that he could complete the work in 4 weeks. On June 3rd, 2024, demolition began on our whole main floor. Once demolition was complete, no one showed up for 2 weeks. We were constantly told there were issues sourcing product, finally, when he showed up with the floor tile, it was not what we had picked but decided to continue anyway to speed up the renovation. It is now August 7th and it still not done. There were several quality issues that were addressed several times and Dan offered to come back to fix these issues for a 3rd time - we declined. The final straw was when we had a subcontractor show up at our house demanding money or he would place a lean on our house. After speaking to this gentleman, we found out that Dan had not paid him and said it was because we owed money - we were paid up to date. When we told Dan we do not want to work with him because of the trouble he has caused, he offered a refund of $1200 for upper kitchen cabinet doors. Even though we were not satisfied with the refund amount, we agreed. We told him to pick up his sign from our home and give us the refund. That was 6 days ago and we've heard nothing from him. We now have to hire another contractor to finish the renovation which is going to cost us more money and time.
