Zeolla Plumbing and Heating is a family operation in Stoughton — Douglas V. Zeolla runs it with his sons Doug Jr. and Derek — and the thing that shows up again and again in its Google reviews is speed: multiple 2026 reviews describe technicians like Mark, Jack, and Justin arriving within 30 to 40 minutes of a call, including one customer who'd been stood up by another plumber on a Friday afternoon and had Zeolla show up on Saturday for a leaking water heater instead. Beyond the response time, the reviews consistently mention the crew cleaning up after themselves and explaining the work in plain terms — one 2026 review praised getting a technician out within 24 hours for a non-emergency call, and several others describe technicians walking customers through what was wrong and what came next before starting. The company specializes in Navien tankless water heater and boiler installation, and in 2024 reviews, long-time customers described years of repeat work — a whole-house water filter system, a water pressure system, and annual maintenance on a tankless unit installed five years earlier. Pricing draws a mixed reaction. Most reviews call it fair or good value, and one 2026 review noted being charged less than the original quote once the job turned out to be a quick fix. But a handful push back: a 2026 review called it the most expensive of three quotes obtained, an October 2025 review said a kitchen faucet replacement wasn't cheap and a follow-up quote for bathroom vanities never arrived, and two older reviews — from 2021 and 2023 — describe a price that grew well past the original quote on a larger renovation and an upsell attempt during a boiler inspection. A 2024 review raised a more serious concern: a tankless water heater installation left a gap the customer measured at over half an inch, and the customer said the company declined to replace the part under its two-year labor warranty and asked not to be contacted again after the review was posted. The company holds an active Massachusetts plumbing license and a Better Business Bureau A+ rating. One inconsistency worth noting: the website states the business was founded in 2005, but a tagline elsewhere on the same site reads 'Since 1993' without explaining the gap. This is a strong call for routine and emergency plumbing work, especially tankless water heater and boiler jobs, given how often customers mention getting a same-day or same-week technician; get a firm, itemized quote up front given the pricing complaints on the larger jobs.

real professionals excelant workers and job well done very satisfied with work
Mark was very professional and very friendly to my 96 old dad, who was so happy to have someone new to talk to. And he cleaned up after himself! If we need anything else, we will be calling your company and asking for him.
This is our second time using Zeolla (this time to install two faucets). The first time was to install a Navien water heater and associated plumbing that turned out really well. These guys were recommended by our realtor and they are super easy to work with, good communication and good pricing. The biggest plus is that their workmanship is exceptional—a rarity these days.
Zeolla Plumbing was very responsive to my call. Mark and Doug were very professional and personable. I'm very pleased with the work performed and the pricing.
It was obvious that the 2 gentlemen that arrived wanted me to be satisfied after they were done. They worked hard while here. I was very happy that they did the work in my bathroom.
