Brennan Plumbing & Heating

What exists on Brennan Plumbing & Heating is a permit trail, not a review file. BuildZoom lists the Arlington company with 11 projects and a run of residential permits — water heaters, boilers and water piping in Arlington and Cambridge — dating from 2013 to 2022. That is bread-and-butter plumbing, pulled steadily over a decade. BuildZoom also lists a Massachusetts plumbing business licence, number 4327, shown as active with a May 2026 expiry. The site marks that entry as not verified, so treat it as the directory's claim and check it against the state board yourself. Beyond the permits, the written record is a single line: a Consumers' Checkbook commenter describing Kevin Brennan as a good plumber and a good person. It carries no date, and one anonymous line is not a basis for rating anyone. If you are considering them for a water heater or boiler replacement — the work the permits actually show — ask for recent local references and a written price before committing.
