John Smith Plumbing is the plumber people call when a water heater gives out. A recent customer said John answered a social media post asking for water heater recommendations and had the new one installed within the week, at a price the customer called very reasonable. A 2024 customer with a leaking water storage tank said John came that night to assess the problem and installed a new tank the next night. A 2023 customer who woke up to a leaking water heater said John coached them by phone on how to turn off the water supply, fit them in for same-day service, did the uninstall, helped clean up the water and dehumidify, and installed the new heater. A 2023 customer who had just closed on a house in Chatham said John diagnosed a toilet leak, cut out a poorly installed section of the drain system and cleaned the work area before leaving. A 2020 BuildZoom reviewer said John Smith came the same day they called, when other plumbing companies said they could not schedule them for a week to ten days. BuildZoom shows 14 permitted plumbing, gas and electrical jobs from 1995 to 2024 across Cape Cod towns including Harwich Port, Chatham and Orleans. Its Massachusetts plumber license, number 32777-PL-J, is active on the state registry under John Smith.
I posted in a social media app seeking recommendations for a water heater replacement and thank goodness, I did. I got a few quotes prior and John commented on my post, I reached out to him and he got it installed within the week at a very reasonable price. Extremely happy with the communication and service received. Extremely professional work and gentleman. Thank you, John!

We were frantic to replace water storage tank. Ours was starting to leak . John was recommended by Tom Heemsmoth, as he is retiring. John was there that night to assess problem, and installed a new tank the next night. How he was able to do it, I'll never know. Price so reasonable. We are so pleased. Wish there were more than 5 stars to give.. Nicest guy. Stellar work. He should be your guy.
John deserves 5 stars. Clever, honest, responsive, and priced reasonably. Had work done in Chatham. I'll call John first next time.
John was absolutely amazing! We woke up to a leaking water heater and water all over the floor and property!! John coached us on the phone on how to turn off the water supply and then worked hard to get us into his schedule for same day service!! HOW AWESOME IS THAT!!!! John worked very hard to get a new water heater, do the uninstall, help clean up the water mess, dehumidify and help us with next steps. He completed a flawless timely install of the new water heater. He and his team are hard working, professional and friendly and got the job done with no issues ! I HIGHLY RECOMMEND HIM!! SMALL BUSINESS ,HARD WORKING ETHIC AND DEDICATION IS SO IMPORTANT AND HARD TO FIND!! I will definitely use him again for plumbing needs!!!
