Repairs, panel upgrades, EV charging and dedicated circuits for Marin and Sonoma County homes. Clear recommendations from a California C-10 electrical contractor.
John Owens Services has served Marin and Sonoma County homes since 1986 and holds California contractor license #501853, including C-10 Electrical. Our electricians handle electrical repair and troubleshooting, home rewiring, electrical panel upgrades, lighting installation, EV charger installation and generators, and we explain the options before recommending work.
From our San Rafael, Petaluma and Santa Rosa locations, we serve Mill Valley, Novato, Tiburon, Larkspur and the surrounding towns. When a project also involves plumbing, heating, cooling or building repair, one company can plan the electrical work with the rest of the job.
Our electricians diagnose the problem, explain your options and recommend repair or replacement based on your home’s needs and the equipment you plan to add.
Not necessarily. We assess existing demand, circuit space, equipment condition and the new load. The result may be a dedicated circuit, compatible load management, or a panel and service upgrade. A 200-amp panel is not a universal requirement.
Price depends on the type of repair or installation, how easy the wiring is to reach, the equipment, and any meter, utility, permit or patching work. We assess the project and explain exactly what the estimate includes.
We serve homes throughout Marin and Sonoma County, including Mill Valley, Novato, Petaluma, San Rafael, Santa Rosa, Tiburon, Larkspur, Corte Madera, Kentfield, San Anselmo and Sebastopol. Use the city links below or contact us to confirm service for your address.
Yes. When the approved project includes related plumbing, heating, cooling, water heating or building work, our teams can often coordinate the work through one company.
Flickering lights, old or damaged wire materials, and sparking outlets or switches are signs that your wiring may need an upgrade.
It could be from a faulty appliance, a problem with the downstream wiring, water that has gotten into the electrical box, or the outlet itself is faulty.
Unplug all your devices from that outlet and turn off power to that room to prevent a fire until an electrician can come inspect the issue.
Lights that frequently dim or flicker, circuit breakers that trip constantly, hot switch plates, or scorch marks around the panel or outlets are signs that the panel is overloaded.
In a modern home, upgrading to GFCI outlets in specific areas, upgrading to a 200-amp panel, replacing old wiring, and having a whole-home surge protector installed are things to consider.
