Ngo Da

Three hundred and twenty-seven permits is a serious run of electrical work, and that is the whole of what is publicly known about Ngo Da. The permits, pulled from a Dorchester address on Fuller Street under owner Da H Ngo, are the bread-and-butter of an older housing stock: 200-amp service upgrades, knob-and-tube circuits torn out and rewired, fire-alarm and smoke-detector wiring, across Dorchester, Hyde Park, Roxbury, Jamaica Plain, Brookline, Newton and Quincy. That run is mostly historical. The activity clusters in 2018 and 2019, with a single permitted project since. The licences are the thing to settle first. BuildZoom lists three for this contractor and shows every one as inactive or expired — including a Massachusetts security systems S-licence, SS-001854, which the site says the Department of Public Safety recorded as cancelled at one point — and it sets its own score to zero because it could not verify an active licence. Directory licence records are wrong often enough that this is not proof of anything, but electrical work in Massachusetts requires a current state licence, so ask for the licence number and check it with the Division of Occupational Licensure before any work starts. No customer has written about the work on that profile. For a homeowner, that means the permit history is the only track record available: ask for the licence, ask for references from recent jobs, and confirm who would actually be pulling the permit.
