Commercial Electricalin Northern California
Electrical capacity quietly decides what a commercial space can become. We handle commercial electrical as part of our construction projects and as standalone work: panel and service upgrades, new circuits, lighting retrofits, and the troubleshooting that ends recurring breaker mysteries.

Common Questions
Commercial Electrical FAQs
Our panel is full — what are the options?+
Sometimes it's a subpanel, sometimes a service upgrade, occasionally just circuit reorganization. We evaluate the load calc first so you pay for the fix you need, not the biggest one.
Is an LED retrofit worth it for a leased space?+
Usually yes if you have 2+ years left on the lease — energy savings plus better light typically beat the payback window. Our lighting survey gives you the actual math for your space.
Do you handle electrical permits and inspections?+
Yes, on every job. Unpermitted electrical is a liability that surfaces at the worst time — sale, insurance claim, or fire inspection.
