Theodore D. Ongaro

Theodore D. Ongaro's general contracting business runs out of 19 Charles St in Winthrop, and the one place it surfaces online is a BuildZoom entry that is all paperwork and no customers. BuildZoom lists two Massachusetts credentials under his name: a Construction Supervisor licence, CS-119610, which it says it verified as active in June 2026, and a Home Improvement Contractor registration, #211548, with an issue date of 28 March 2026. Those are BuildZoom's own claims rather than a registry check, and directory licence entries go stale or attach to the wrong person often enough that both numbers are worth confirming with the Department of Public Safety and Consumer Affairs before you sign anything. BuildZoom hasn't received a single review for him. That, not anything negative, is why he goes unrated here. If you are weighing him for a Winthrop remodel, treat this as a starting point rather than a verdict: ask for recent local references, and confirm the licences and insurance certificates yourself.
