# All In One Plumbing

**Trade:** Plumbing · **Address:** 884 Queen Anne Rd, Harwich, MA 02645 · **Phone:** (508) 432-3234 · **Languages:** English

**Rating: 3.0/5** (low confidence) — from 1 reviews across 4 sources.

## The honest read

All In One Plumbing is a one-person Harwich plumbing and heating operation run by sole proprietor Mark E. Hatch, in business since May 2006 and covering the Lower and Outer Cape roughly from Dennis to Wellfleet, per its BBB profile (registered there as "All In One Plumbing and Heating").

Hatch holds an active, state-registry-verified Massachusetts plumbing license (13076-PL-M) issued to Mark Hatch, matching the owner of record. His BBB profile carries an A+ underlying rating with no complaints on file, though the business itself has not sought BBB accreditation. Building-permit records show 21 filed plumbing, gas, and related jobs across Harwich, Orleans, Eastham, Chatham, Yarmouth Port, and Centerville between 2014 and 2024, evidence of a steady, ongoing practice.

Customer feedback is thin. The only retrievable review is a five-star Google rating from 2020, whose author simply called Hatch "the best plumber in the world" without describing the job. There isn't enough written detail to say what kind of work he's specifically best known for beyond general residential plumbing and heating service, so it's worth asking directly for recent references and current availability.

For a small, license-verified, long-running local plumber on the Lower Cape, this is a reasonable business to get a quote from — just confirm scope, pricing, and scheduling up front given how little public review history exists.

**Strengths:**
- Verified active license — state registry confirms Mark Hatch's MA plumbing license
- Established since 2006 — nearly two decades as a Harwich sole proprietorship
- Clean BBB record — A+ underlying BBB rating with no complaints filed

**Concerns:**
- Thin review history — only one dated Google review, from 2020

**Where sources disagree:**
- BBB displays an A+ underlying BBB rating on a profile that explicitly states the business is NOT a BBB Accredited Business — two separate facts, not one.
- BuildZoom labels its own license records 'License Not Verified'; the state registry independently confirms the plumbing license (13076-PL-M) active under owner Mark Hatch.
- BuildZoom lists an unrelated, inactive Sheet Metal registration (#9900) alongside the active plumbing license — not a plumbing credential and not evidence of any current issue.
