T Halloran plumbing

Six hundred and sixty-three permits, and not one customer review anywhere. That is the whole shape of T Halloran plumbing, a plumbing outfit working out of 826 Dale St in North Andover. The permit trail is the only real record of the work, and it is narrow and repetitive in a way that tells you something: the jobs sampled on BuildZoom are residential water-heater replacements in Methuen, each pulled as a paired plumbing and gas permit. This is a swap-the-tank, hook-up-the-gas shop rather than a bathroom-gut operation, and it has done that job hundreds of times. BuildZoom gives the company a score of 102 and calls that the top 11% of Massachusetts licensed contractors. Worth knowing what that number is: it is calculated from permit history, not from anything a homeowner said. BuildZoom states plainly that it has received no reviews for this contractor at all. The licence line needs the same care. BuildZoom shows Massachusetts journeyman plumber number 24833 as active, but stamps the same block "License Not Verified" and notes the licence carried an expiration of May 2024 when the site last looked. That is a directory's stale claim, not a confirmation, and nothing here verifies it against the state. If you need a water heater replaced in the Merrimack Valley, this is a shop with a long, documented run of exactly that job. Before booking, ask for the current licence number and check it directly with the Commonwealth, and ask for a couple of recent customer references — there is no public review history to lean on.
