Jason M Olivieri

One directory entry, no reviews, and a licence line that needs a phone call before anything else — that is the whole public record on Jason M Olivieri. He is listed as a Haverhill, Massachusetts plumber, with work spanning boilers and water heaters, gas and piping, septic systems and fire sprinkler systems. That is a broad mechanical range for a one-name shop, and it is the kind of work that has to be permitted and inspected. BuildZoom shows Massachusetts plumber licence #15208 under a "License Not Verified" heading, says the number it last saw carried a May 2024 expiration, and flags that no active licence is on file. Read that carefully: it is the directory reporting what it could and could not confirm, not the state saying anything. Plumbing in Massachusetts does require a licence, though, so this is the first thing to settle rather than a footnote. Beyond that there is nothing — no customer reviews on BuildZoom, no permit history there, and no profile on any other review platform, so no homeowner has left an account of how the work went. Before booking anything, ask for the licence number and check it directly against the Massachusetts Division of Occupational Licensure's e-licensing lookup, and ask for a certificate of insurance. If the licence checks out and you can get a couple of recent local references, the range of work on offer is genuinely useful; without that confirmation, keep looking.
