Albert H. Cairns

Albert H. Cairns is a one-man plumbing operation out of Stoneham, and the paper trail behind it is much thinner than the years suggest. The business side of it, A.H.C. Mechanical Contractors, Inc., has been incorporated since April 1982 and carries a single employee on its BBB file, where it holds an A+ grade. That grade comes with a caveat worth reading plainly: the company is not BBB Accredited, and its BBB file was only opened in 2017, decades after it started trading. What's missing here is customers. No reviews are published on either page — BuildZoom says outright that it has received none. Its BuildZoom score of 90 is calculated from permit filings, not from anyone's opinion of the work, so it should not be read as a rating. The permit history itself is the most concrete thing on file: six permitted jobs between 2011 and 2021, spread across Boston, Belmont, Beverly, Danvers and two residential plumbing and gas permits in Methuen. The work described is bread-and-butter mechanical plumbing — boilers and water heaters, sewer laterals, septic systems, fire sprinkler lines. Before booking, ask about licensing directly. BuildZoom prints two Massachusetts records for him and flags both "License Not Verified": a plumber's licence #9651 running to May 2026, and a consumer-affairs registration #18648 that BuildZoom labels active while printing a May 2016 expiry. Neither has been checked against the state registry, and those two statements cannot both be true. This is a small shop with a long incorporation date and almost no public track record — reasonable for a straightforward plumbing call if you verify the licence with the Commonwealth yourself and ask for recent local references.
