3G's Plumbing & Heating Inc.

3G's Plumbing & Heating Inc. works out of 188 Main Street (Route 28) in Dennis Port, in the middle of the Cape's mid-Cape corridor, and is the kind of shop homeowners call when the heat quits or a pipe lets go. Its Google profile carries 4.3 stars from 15 ratings, and a commenter on a Cape Cod plumber thread named the company when neighbours were asked who they use. The reviews that describe actual jobs are consistent about two things: the company answers, and the technicians know their trade. In a December 2025 review, a homeowner whose heat failed on a cold Saturday night before Christmas wrote that after two other companies turned them down, they called 3G's on a neighbour's recommendation, got a prompt call back, and had someone at the house in a little over an hour who diagnosed the problem on the spot. A July 2025 reviewer described years of repeat work — panicked calls taken kindly by the office, one technician usually assigned, another handling a broken sink pipe the day they wrote. A 2021 review described a toilet and tub backing up and being fixed on a repeat visit, and a 2023 reviewer called the company professional, honest, on time and thorough. The complaints are about reaching them, not about the work. One reviewer in 2023 left a single line — too busy to call back — and a 2021 reviewer described a rude phone experience with the office and being hung up on. Both are one-line accounts with no job attached, and they sit alongside repeat customers who praise the same office by name, but they are the pattern worth knowing: this is a busy shop and the front desk is where the friction shows up. Before booking, ask directly about scheduling and how they handle a first-time caller versus an existing customer, since the standout review turns on exactly that. Nothing in the record describes pricing, so ask for the rate structure and whether you will be quoted before work starts. And note that individual technicians are named repeatedly in the praise — worth asking who is assigned to your job. For a mid-Cape homeowner with a heating failure or a plumbing emergency, this is a company with a decade-spanning record of showing up and fixing it; a homeowner who needs careful hand-holding through scheduling should confirm expectations on the phone first.
