 Trustindex verifies that the original source of the review is Google. Vaughn was great! He was pretty sure what the problem was but did his due diligence. He confirmed that we were okay with the invasive work required and, as with all our John the Plumber folks, confirmed the price was okay before proceeding. Will keep using John the Plumber.

 Trustindex verifies that the original source of the review is Google. 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!

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!
