About Castro Electric Corp
Castro Electric Corp has spent years earning Stoneham's trust one job at a time, and it shows — a perfect 5.0 rating across 250 reviews doesn't happen by accident. Rene, Taylor, George, and the rest of the crew treat every home like their own, protecting floors, clearing debris, and leaving each job site as clean as they found it. Whether it's a late-night breaker emergency or a scheduled upgrade, they show up when they say they will and explain exactly what's happening before any panel is opened.
Stoneham's housing stock tells a story most electricians outside the area miss. Colonials and capes built before the 1960s were often wired with knob-and-tube, and many still run on undersized 60A or 100A services that can't keep pace with modern HVAC, EV chargers, and kitchen appliances. Castro Electric specializes in tracing and safely retiring old knob-and-tube runs and executing clean 200A service heavy-ups that bring a home's entire electrical backbone up to code — not just a single outlet or fixture.
That same precision carries into the finish work homeowners actually see every day: tight, evenly spaced recessed lighting layouts that follow a room's architecture instead of a generic grid, and EV charger installs routed cleanly from breaker to garage. From emergency dryer breaker repairs to full-home rewiring, Castro Electric backs it all with licensed, insured work and the kind of communication — like Alba's scheduling coordination — that makes a stressful electrical problem feel manageable.
