## The honest read

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.

**Strengths:**
- Deep permit history — 101 recorded plumbing and gas permits across South Shore towns
- Top-ranked by BuildZoom — contractor score in the top 10% of Massachusetts contractors tracked
- Active state license — Massachusetts plumbing license verified active

**Concerns:**
- Extra license numbers — BuildZoom lists two more Massachusetts numbers beyond the registry one
- Status mismatch — BuildZoom shows license #3169 as both Active and Unable To Verify

**Where sources disagree:**
- BuildZoom's own pages disagree on license #3169's status — one shows it Active, another Unable To Verify.
