JJ Sullivan Plumbing & Htg. Co., Inc.

Two construction directories carry JJ Sullivan Plumbing & Htg., and between them they hold 195 permitted projects and not one customer review. The Woburn company, listed under owner Joseph J Sullivan, presents itself on Procore as a specialty plumbing contractor working both commercial and residential jobs across Massachusetts, with 69 projects logged there since it joined the platform in April 2022. BuildZoom's permit-derived profile is the deeper of the two: 195 permitted projects and a proprietary BuildZoom score of 101. Its posted service list runs to boilers and water heaters, gas and piping, fire sprinkler systems, sewer laterals and septic systems — a mix weighted toward building systems rather than everyday fixture repairs. What neither profile has is anyone who hired them. Both carry zero written reviews, so there is no customer account here to weigh, and nothing supports a rating. The licence picture needs checking directly. BuildZoom lists five Massachusetts licence records for the company: a Plumbing Business record and a plumber number it shows as active but marks unverified, a master pipefitter licence it says it has not rechecked since January 2010, and two more — an unrestricted master pipefitter and a construction supervisor licence — that it reports as inactive and at one point cancelled. Directory licence records attach to the wrong business often enough that none of that counts as confirmation. If you call them, it is likely for plumbing and gas work on a building rather than a Saturday leak. Get their current licence numbers and check them against the state board yourself, and ask for job references — that is the one thing neither listing supplies.
