## The honest read

John G Latham Inc is a plumbing, heating, and air-conditioning business at 83 Cathedral Rd in Brewster, Massachusetts, run as a sole proprietorship by John Latham. The company has been in business since 1984, 42 years, according to its Better Business Bureau profile, which also lists plumbing, heating, and air conditioning as its offered services.

The company's plumbing license, #9101-PL-M, is verified active by the Massachusetts state licensing board under John Latham's name, a genuine, government-checked credential rather than a directory's self-reported claim.

The one written account on file is a glowing 2020 Google review from a longtime customer who says the business provided excellent service to two generations of their family, describing the work as reliable, honest, prompt, and effective. That same review congratulates Jack, likely a nickname for John, on an upcoming retirement, though it isn't clear from the evidence whether that meant the owner or a staff member, or how it affected the business afterward.

Beyond that one review and a 5-star average from two Google ratings, there isn't much recent written record to go on. BuildZoom's page for the company also lists several other Massachusetts license records, most marked inactive or cancelled, plus two more (General Contractor and Electrical Contractor) that share an identical license number and are filed under Newton, a different city from the company's Brewster address; those look like a mismatch rather than a second registration for this business, and none of it changes the one credential that is independently verified: the active MA plumbing license.

Anyone considering this company for plumbing, heating, or air-conditioning work in Brewster or nearby has a verified, decades-old license to point to, but should ask directly about current staffing and availability, and whether the 2020 review's mention of a retirement affected day-to-day operations.

**Strengths:**
- Multi-generational customers — one reviewer praises decades of reliable, honest service
- State-verified plumbing license — MA registry confirms an active license under the owner's name
- Long tenure — BBB records a 1984 start, 42 years in business

**Concerns:**
- Thin review base — only one written review and two Google ratings on file
- Staff retirement noted — a 2020 review referenced an employee's planned retirement
- Unverified license bundle — BuildZoom lists cancelled and mismatched-city license records

**Where sources disagree:**
- BuildZoom lists a General Contractor and an Electrical Contractor license sharing the identical number #112260 under Newton, MA, a different city from this business's Brewster, MA address; these do not appear to belong to this business and are not part of its verified record.
- BuildZoom shows three additional Massachusetts license records (Home Improvement Contractor #101984, Construction Supervisor CS-005869, an unnumbered Plumbing Business license) as inactive/cancelled, directory-reported only, not independently verified against the state registry.
- BuildZoom's Score of 0 is permit-derived data, not customer sentiment, and should not be read as a poor customer rating.
