Juan F. Mendoza

Juan F. Mendoza works out of 45 Winthrop St in Winthrop, and beyond that the public trail runs out fast. BuildZoom lists a Massachusetts home improvement contractor registration, #196178, which it says it checked as active in March 2026 — that is the directory's listing, not a registry confirmation. Its page carries no customer reviews, no permit history and no published projects. The BuildZoom score of 90 reads like a quality grade but isn't one: the page itself explains the number means only that the contractor is licensed or registered and that BuildZoom holds nothing further about them. A home improvement contractor registration is the credential for nonstructural residential work, so the scope here is ordinary remodeling and repairs. With nothing else on file, ask for a list of recent local jobs and the homeowners you can call, and check the registration number yourself with Consumer Affairs before any money changes hands.
