Breakers that trip when two appliances run, warm or buzzing panel covers, a fuse box instead of breakers, no open slots, rust or scorch marks, or a brand with a known failure history such as Federal Pacific, Zinsco or Sylvania. Insurance carriers and buyers in Mendocino County often flag these panels during a sale.
New main breaker panel, new grounding and bonding to current code, labeled circuits, meter socket and service entrance work coordinated with the utility, permit and city inspection. Where you want to keep the existing panel we can add a sub panel for a garage, workshop, ADU or EV charger.
Cost depends on amperage, whether the meter and service entrance need replacing, and how the utility feeds the property. We give a fixed written price after a short on-site evaluation. Call (833) 652-8933 to schedule one in Mendocino or nearby Caspar, Little River, Fort Bragg, Albion.
