Ryen and Jordan did an exceptional job addressing a kitchen sink that wouldn't drain. They were professional, hunted the problem until it was resolved, and then made a quick fix to help prevent the issue from reoccurring. Moreover, they quoted me for a proper longterm fix and weren't aggressive or pushy. They blew my expectations out of the water and I wouldn't hesitate with using them again in the future. I hope that their great work and friendly disposition doesn't go unnoticed by any higher-ups!

I can't say enough good things about Matt and Elia from John the Plumber! Not only are they excellent problem solvers who really know their stuff, but they're also genuinely great people. They arrived right on time, were incredibly efficient, and were super friendly and professional throughout the entire experience. It's refreshing to deal with people who not only take pride in their work but also make the whole experience pleasant and stress-free. They went above and beyond, and their positive attitudes and dedication really stood out. I highly recommend Matt and Elia to anyone looking for reliable, knowledgeable, and genuinely caring plumbers. John the Plumber is lucky to have these two on their team! Thanks again, guys, for the outstanding service!

Had Tomas and his team come in to install a new sump pump pit system with backup. They did a fantastic job. They kept the worksite meticulously clean and kept me informed of all the steps as they happened. They accommodated a couple changes very easily and now I have peace of mind in case there is another flooding event. Would work with them again in a heartbeat
