3G's Plumbing & Heating is a Dennis Port shop whose reviews keep coming back to one thing: getting to a broken heater or a backed-up toilet fast, even on a holiday weekend. Google shows a 4.3-star rating from 15 ratings, and the same names — Justin, Heather, Jared — show up again and again in what customers write. In a December 2025 review, a homeowner described the heat going out on a cold Saturday night before Christmas; after two other companies turned them away for not being existing customers, 3G's Justin called back, said 'I want you to have heat,' and was at the house within a little over an hour. A July 2025 review from a longtime customer named all three — Heather fielding the panicked calls, Justin doing most of the work, Jared fixing a broken sink pipe that same day — and called it 'a solid company that's good to their customers.' Earlier reviews, from 2021 and 2023, describe Justin fixing a backed-up toilet and tub and other jobs handled 'professional, honest, on time.' The record isn't spotless: a 2023 review said the company was too busy to return a call, and a 2021 review described a rude, snappy secretary who hung up on the caller. Both are older complaints against a backdrop of repeat, name-checked praise for the actual plumbing and heating work — worth confirming you're through to the right person if you're calling for the first time.
“3G's Plumbing & Heating”
Highly recommend! On a cold Saturday night the week leading to Christmas, I discovered the heat was not working. After trying 2 other compamies; one being Whitely who wouldn’t come because I wasn’t an existing customer (even though they advertise 24x7 serviceand I could’ve become a customer)…I went to a neighbor who recommended 3G’s. Well, things happen for a reason! I received a prompt call back from Justin; the first thing he said is “I want you to have heat”, not “are you an existing customer?” and he was at the house in a little over an hour. He quickly diagnosed the problem and showed me the part that had cracked. He had to go back to the shop for a part, but was back quickly and had the heat back on!! The ambient temp in the house had already dropped to 55, so we were beyond grateful to have the heat restored. Turns out it’s time to consider a new system, so we will invest with 3G’s for that as well as future service. Being a good neighbor as a business and helping people when you’re in a position to do so is still important, and 3G’s and Justin demonstrated that. They prioritized the need and service, whether or not I was a customer. And now I will be!! Thank you!!
I’ve been using them for years and they are always there when you need them. Highly recommend! Heather takes all my panicked calls and is so kind. I usually get Justin who is awesome but everyone is great. Jared got the broken sink pipe today. It’s just a solid company that’s good to their customers!
