Donald P. Sullivan

Donald P. Sullivan works out of 3 Beverly Ave in Winthrop, and what sits on the public record is paperwork: four Massachusetts licence numbers listed under the name, one of them a master plumber number. BuildZoom is careful to say it hasn't verified any of them. The most recent expiration date it reports seeing on those numbers is July 2016, and three projects are attached to the profile. That is genuinely all there is. Before booking, ask for the current master plumber number and check it yourself against the Massachusetts licensing board — and ask for a couple of recent local references, because nothing published here speaks to how the work goes.
