Called John The Plumber and got a next day appointment. Cameron showed up on time and was very professional. He quickly assessed I needed a shut off valve installed in the basement. He explained the work required along with fees. He performed the work easily, while respecting our home. Extremely satisfied and highly recommend this business.

Saturday emergency and John the Plumber was fast to respond (within 20 minutes of calling) versus others who shrugged off the issue and said they could come the next day. Plumber who arrived was friendly, professional and efficient. Our new go to for all plumbing. Thanks for the exceptional service!

Thomas was great. He carefully listened to all the issues and made recommendations. Some were easy fixes that cost nothing. He did not try to over sell us. He worked quickly. We will call John the Plumber again for sure.

Sheila Buchanan on John The Plumber

First time using John the Plumber to install a new water heater. The service was top- notch from beginning to end: super friendly staff from Lisa on the phone to Cole who came do the quote to Tyler the HVAC tech who did the installation quickly. Prompt and professional service, and their online billing system was convenient and seamless. Highly recommend based on my experience.
