Z Plumberz

I couldn’t be more grateful for the incredible job Zack Michelle with ZPlumberz did fixing my Navien on-demand hot water system! From start to finish, Zack was not only professional, but also genuinely enthusiastic and passionate about his craft. The repair went exactly as he predicted — he identified and replaced the faulty part right in front of me, and like magic, I had hot water again! What stood out most was Zack’s willingness to explain everything in detail. He walked me through how the system works and even offered insightful tips about filtering water going into the unit and helping maintain cleaner tap water. He patiently answered all of my (many!) technical questions with knowledge and kindness. Zack is truly a rare find — a curious, considerate, and deeply knowledgeable heating and plumbing expert who takes real pride in his work. I would not hesitate to call on him again in the future and highly recommend him to anyone needing top-tier plumbing support. He’s a total pro and a joy to work with!

Update: 12/17/2025 was finally able to get them back to finish the install. Apparently there were a couple of internal issues that prevented them from finishing in a timely manner and never communicated this to any of their customers. I'll give them some leeway, but the communication needs improved. 5* plumbers with 0* customer service. I schedule a water heater and water filter install 2 weeks ago. After the water heater install, we had issues with no hot water -- all of the calls for 2 days were picked up by their "national call center" (ie., glorified answering machine). Eventually, I had to email their billing person to get the plumber to eventually call back. Luckily I'm handy enough that we were able to troubleshoot over the phone, otherwise we'd likely would have had to wait days to get it fixed. I'm still waiting on the water filter install; again, 0 communication from ZPLUMPERZ. I've had it "scheduled in their books" now twice (once after the in-person install and once after the troubleshooting call), and both times no one has shown or even bothered to call. Hopefully this review will get someone in the Boston office to take notice and actually respond.

I called November 28th 2025 at 9am. They said a plumber would be there between 11:00 and 11:30am. I am still waiting for a plumber to arrive. There call center staff are dishonest. I called multiple times and they kept saying a plumber would be there soon. Do not trust this company. Keep searching until you find a plumber who answers their own calls. The call centers just want to harvest data and resale it.
