Customer Reviews

Marc Hirshberg

Was referred to Thornhill Pool Services by a friend for an urgent maintenance issue after opening the pool for the summer. They came next day to diagnose the problem and within 24 hours to fix the issue. Great service and very reliable and will continue to use them for all our pool servicing.

From the start, working with Jacob and his team at Thornhill Pools was a great experience. After facing repeated issues with a previous pool service provider, we were relieved when Jacob responded quickly and came out right away. He and his team took the time to inspect every single piece of equipment to ensure everything was functioning properly. Not only did they resolve the issues efficiently, but Jacob also explained how the entire pool system works so we could better understand and maintain it ourselves. He went above and beyond, even stopping by every other day to monitor the pool and make sure everything stayed in top shape. Jacob was professional, responsive, and genuinely committed to getting things right. We highly recommend Jacob and Thornhill Pools to anyone looking for reliable, high-quality pool service.

Samuel and Jacob run a professional shop. I have been using their service for a few years and I am very satisfied. They respond to messages and questions quickly, they are always on-time, and they do a thorough job. It's a family run business and the entire Thornhill Pool Service team take care and pride in their work. I cannot recommend them enough for all your pool needs.
