Castro Electric Corp

The firmest thing on file about Castro Electric Corp is its licence: Massachusetts electrician registration 9349 is active and held under the company's own name. Rene Castro started the business — the site names him as founder but gives no year. The company describes residential and commercial work out of Stoneham and North Reading: panel upgrades, wiring, EV chargers, lighting, generators, and emergency calls around the clock. It lists a service area running from Stoneham and Woburn through Reading, North Reading, Wakefield, Winchester, Andover, Lynnfield, Melrose, Burlington, Medford, Malden, Saugus, Peabody and Danvers. The customer record is short. Five reviews are on file, every one of them posted within five days of each other in March 2026, and every one five stars. They praise punctual, clean work and a fair price, and one customer asks for Rene by name. None describes an actual job — no panel, no fixture, no timeline — so there is little in them to weigh beyond a good first impression. That makes this a licensed shop with a thin public track record rather than a long-proven one, which is a reason for caution, not suspicion. Reasonable to call for panel work, an EV charger or an after-hours emergency around the Stoneham and North Reading corridor. Ask for references on a job the size of yours, and get the scope and the price in writing before anyone starts.
