## The honest read

Kevin Klein is a solo Cambridge plumber whose state license is verified active, and BuildZoom's permit records show 168 small plumbing and gas jobs filed across Brookline, Boston, Brighton, and nearby towns — mostly repairs and installs under $5,000.

The handful of reviews on file, from 2019 through 2022, describe the same kind of call: a water heater that needed swapping out fast, or a repair done cleanly and on time. A 2022 review credits him with getting hot water back quickly after an emergency swap; the 2019 reviews describe him as prompt, communicative, and workmanlike, cleaning up the area when finished.

His official Massachusetts plumbing license, 12088-PL-M, is active and verified directly with the state, good through 2028. BuildZoom's own listing for that same number is inconsistent — it's shown as active in one place but flagged 'not verified' and reported as no active license elsewhere on the same profile — and a separate, older license number tied to a plumbing corporation shows up as both active and cancelled in BuildZoom's historical records. None of that changes what the state registry itself confirms.

For a straightforward plumbing repair or a water heater swap, Kevin Klein is a reasonable call backed by a verified, current license — just don't be thrown off by the mismatched details on his BuildZoom listing.

**Strengths:**
- Verified license — Massachusetts plumber registration active through 2028
- Fast water heater fixes — praised for quick swaps restoring hot water
- Clean, prompt work — 2019 reviews cite tidy job sites and good communication

**Concerns:**
- BuildZoom mismatch — that listing shows conflicting active/inactive license details

**Where sources disagree:**
- BuildZoom's historical records show an older license tied to a plumbing corporation (#3454) as both active and, separately, cancelled by the Commonwealth.
