Greenlight Home Services

Greenlight Home Services is a Sagamore Beach-based plumbing, heating, drain cleaning, and water filtration company serving Plymouth and Barnstable County, largely built around one plumber, Josh, who the company says has almost two decades of experience in the trade. Its Massachusetts plumber license is active, the Better Business Bureau gives it an A grade, and on Google it holds a 5.0-star average from 98 ratings. The written record is deep and remarkably consistent — 84 reviews from 2024 through this year, 13 of them in just the past six months, with essentially no negative ones among them. Josh's range shows up across the reviews: gas leaks (including one found during a meter swap that he coordinated directly with the town inspector to resolve), a failed gas boiler fixed same-day with a new sensor after an overnight breakdown, a complicated multi-zone heating system with no heat that took several hours to diagnose and a return trip with a part to finish right, and a cast-iron septic pipe accessed and replaced from behind a wall in a genuinely difficult crawl space. During a hard freeze, he dug through frozen ground to replace heat tape and get a customer's water running again. On the more routine side, reviewers describe same-day drain cleaning, a backflow valve replacement completed the day it was quoted, and a tankless water heater serviced alongside a leaking whole-house water filter. Communication and responsiveness come up in nearly every account: customers describe Josh answering the phone himself, texting back quickly, giving clear quotes before starting, and explaining the work as he goes — one customer specifically noted he was the first plumber to actually answer the phone after they'd struggled to reach anyone else about a gas leak. There is one clear exception in the record: a July 2025 review describes Josh doing additional work on an emergency call after another plumber had already fixed the original problem, and the customer felt a $350 charge for that extra work wasn't justified. It's the lone negative account among dozens of detailed positive ones. For a Cape-area homeowner facing anything from a routine clog to a genuine gas or heating emergency, this is an unusually well-documented, highly responsive option — the kind of record built by one plumber who personally shows up and follows through.
