Gregory Family Plumbing Heating

Gregory Family Plumbing, Heating, and Air Conditioning is a one-man shop run out of Marshfield by owner Mark Gregory, who's held it as a sole proprietorship for 19 years according to the Better Business Bureau. The town permit record tells the story here: BuildZoom counts 101 building permits pulled under the business, mostly plumbing and gas work spread across South Shore towns, and scores it 103 — in the top 10% of Massachusetts contractors it tracks. Its Massachusetts plumbing license is active on the state registry, held by Mark Gregory personally. BuildZoom's own listings show a couple of loose ends worth asking about directly: the company appears under more than one license number there, and one of those numbers, #3169, shows up as both Active and Unable To Verify on different BuildZoom pages. This looks like a solid call for straightforward plumbing, gas piping, and heating/AC service work from a business with a long, well-documented permit history — worth confirming the extra license numbers before booking.
