About JDO Electric
JDO Electric, led by Jim, is a Somerville-based electrical contractor built on a simple promise: show up on time, communicate clearly, and leave every home better than we found it. From the triple-deckers of Spring Hill to the historic colonials near Prospect Hill, we know the aging housing stock of this city inside and out — including the knob-and-tube wiring hiding behind plaster walls in pre-1940s homes. Our team specializes in safe, code-compliant remediation that restores your home's safety, insurability, and resale value.
Many older Somerville properties still run on undersized 60A or 100A service that simply can't keep up with modern demands like EV chargers, heat pumps, and central air. JDO Electric performs complete service heavy-ups to 200A — new panels, meter bases, grounding, and permitting handled end-to-end. And when it comes to the details that make a house feel like home, our architectural recessed lighting and fixture installations are second to none: perfectly centered pendants over your dining table, dimmable canless LEDs in vaulted ceilings, and clean patching where old fixtures used to be.
Homeowners across Somerville, Cambridge, Medford, and Watertown consistently praise Jim's communication — immediate, continuous, and honest from first call to final walkthrough. Whether it's a single ceiling fan with no existing wiring or a full panel replacement with an EV charger, every job gets the same respectful, shoe-covers-on treatment. That's why our neighbors rate us 4.9 stars and keep calling us back, room by room, project by project.
