About Russell Electric

Russell Electric is a licensed C-10 electrical contractor based in Castro Valley, California, serving homeowners, property managers, and general contractors across the San Francisco Bay Area. Founded in 2017, the company has completed over 500 projects ranging from knob-and-tube rewires in century-old homes to full commercial tenant improvements and 400-amp service upgrades for growing businesses.

The company serves two primary audiences. For residential clients, Russell Electric handles panel upgrades, EV charger installations, whole-home rewires, emergency electrical service, and dedicated circuits for kitchen and bathroom remodels. For commercial clients and general contractors, the company offers tenant improvement buildouts, new construction rough-in, three-phase power installation, EV charging infrastructure, underground conduit, and low-voltage data wiring — with a 48-hour bid turnaround that GCs rely on to keep their projects on schedule.

Russell Electric operates under California C-10 License #1106773 and carries full liability insurance, workers' compensation coverage, and a contractor's bond. Every project is permitted, inspected, and completed to code — the company has never failed a final inspection on a permitted job. The team pulls permits directly, coordinates with PG&E and local inspection offices, and leaves job sites clean.

The company is built and operated by Mason Russell and a team of Bay Area-based electricians who understand the region's older building stock, unique permit requirements, and inspection processes. Russell Electric is Bay Area born and based, and takes pride in being the electrical sub that general contractors call back project after project.
