## The honest read

Fifteen Thumbtack ratings, every one of them five stars, and the same first name runs through all of them: Anthony. AWM Mechanical is a Leominster plumbing and heating shop, and the company says it is owned and operated by licensed Master Plumber Anthony Marcello, with roughly ten years behind it and a family-owned setup.

Both plumbing licences check out against the state registries. Massachusetts shows plumber licence 9628881-PL-M active in Anthony William Marcello's name, and New Hampshire shows 2500486 active as well. That matters here, because the company works both sides of the border — it describes its territory as Central and Eastern Massachusetts and southern New Hampshire, with gas piping offered on the Massachusetts side.

The written history is short but consistent. Four customer accounts run from 2023 through August 2025, and they tell the same story. A 2024 Thumbtack reviewer with a sudden water-pressure problem said Anthony arrived promptly, assessed it, and resolved it. A 2023 review credited him with locating and fixing the issue and said they would call again for maintenance. A January 2025 Google reviewer cited quick service and clear communication, and the August 2025 Thumbtack account described fast, patient work and easy back-and-forth. Twenty-three projects are shown on the Thumbtack profile; Google carries a single 5-star rating.

The Better Business Bureau grades the business A- and lists it as AWM Mechanical Plumbing & Heating in Leominster with Anthony Marcello as owner. One wrinkle: the BBB category reads Heating and Air Conditioning, while the company's own description and its Thumbtack profile lead with plumbing. If you are calling about heating or cooling rather than a pipe, ask how much of that work he actually takes on.

What to know before calling: the trail is thin and none of it is from the past year, so you would be hiring on a handful of accounts rather than a deep bench. It is also worth confirming coverage for your own town — the stated territory stretches from Central Massachusetts into southern New Hampshire, a wide range for one master plumber.

The right call for straightforward residential plumbing and heating work — pipe repair and replacement, water heater swaps, gas lines, emergency calls — where you want the licensed owner doing the job himself. Pin down scheduling and whether your address falls inside his territory when you call.

**Strengths:**
- Licences verified — active plumber registrations in both Massachusetts and New Hampshire
- Perfect Thumbtack record — all 15 ratings are five stars
- Fast on site — reviewers describe prompt arrival and same-visit fixes
- Clear communication — customers cite quick, easy back-and-forth

**Concerns:**
- Thin review trail — four customer accounts, none from the past year
- Wide stated territory — confirm coverage from Central Massachusetts into southern New Hampshire
- Category mismatch — BBB lists it under heating and air conditioning

**Where sources disagree:**
- The Better Business Bureau categorizes the business as Heating and Air Conditioning, while the company's own site and its Thumbtack profile describe it primarily as plumbing and heating.
