From time to time, one is lucky to deal with a company that outperforms and delivers well above expectations. Top Torch with Chris and Zach falls easily within this description after a recent membrane replacement project at St Columba Uniting Church, Woollahra. They are truly an exceptional company and team, delivering a top-tier service with world-class products. Working throughout a long weekend to complete the project due to weather constraints, just showcasing their true commitment. Top Torch and its team are highly recommended and certainly worth your consideration!
After having our roof redone three years ago by another contractor, we suffered through constant, frustrating leaks. We brought Zach in—who came highly recommended to us by the material supply company—and the experience was a total breath of fresh air. Zach and his team were professional, timely, and completely trustworthy from start to finish. Their work was competitively priced, and the standard of their craftsmanship was exceptional. Beyond their technical skill, the Toptorch team genuinely care about the quality of their work and take real pride in the result. Zach also showed a lot of empathy for the fact that we had been misled and poorly treated by the previous roofer. He and his team went above and beyond to ensure our roof was completely redone before the next round of forecasted storms. Most importantly, since they finished the job, we haven't had a single leak. We cannot recommend Zach and Toptorch Waterproofing enough.
Chris and Zack from TopTorch Waterproofing did an outstanding job. Their attention to detail was second to none, and it was obvious they genuinely care about getting everything right. No matter what challenge came up, they always had a solution and took the time to explain the best approach without cutting corners. The quality of their workmanship is exceptional, they left everything clean and tidy, and the whole process was stress-free from start to finish. It's hard to find tradespeople who take this much pride in their work. I wouldn't hesitate to recommend Chris and Zack to anyone looking for waterproofing done properly.
Both myself and a very seasoned Builder researched different waterproofing options for a very unique project for almost two years before we met Chris from Top Torch Waterproofing and we wish we met him at the very beginning! Chris was by far the most professional, knowledgeable and experienced person we both dealt with in this industry and he made the whole process from start to finish so easy for everyone involved in our project. His product and application knowledge is vast and his ability to communicate effectively throughout the project with multiple tradesmen across different disciplines was most appreciated. Everyone who spoke with Chris and saw his work independently told me how impressed they were and how solid and thorough his work was. I look forward to recommending Top Torch Waterproofing in the future to everyone!
Top Torch Waterproofing provided excellent service with professional workmanship. The team was punctual, efficient, and delivered high-quality waterproofing results. I would definitely recommend them for reliable waterproofing solutions.
