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.Posted on 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!Posted on Google![]()
