Stephan M. Woodsum

Twenty-five permits and exactly one customer review — that lopsided ratio is the first thing to know about Stephan M. Woodsum, a one-man plumbing operation working out of Haverhill. The work itself is well documented. BuildZoom's permit history runs to 25 pulled jobs across the North Shore and Merrimack Valley, and the pattern is consistent: gas fitting, boiler installs, and everyday plumbing. That is the paper trail of someone who has been doing licensed gas and plumbing work in these towns for years, not a name that appeared last season. The reputation side is where it thins out. Only one homeowner has rated him on BuildZoom, and that rating is a 2. With a single voice on the record and nothing recent to weigh against it, there is no way to tell whether that experience was typical or an outlier — which is why the read here stays cautious rather than either warm or damning. On credentials, be precise: BuildZoom lists a Massachusetts plumber license, number 13335, showing active with a May 2026 expiration, and that is the directory's own record, not a registry confirmation. The same page also carries older Master Plumber entries that expired back in May 2016. Ask him to show the current license himself. He is a reasonable call for gas and boiler work in the Haverhill area, where the permit record is real and specific. Before booking, confirm the license directly with the state, and ask for a couple of recent customer references — the public ones simply aren't there yet.
