Complex network of electrical wiring and control panels in an industrial setting.

Electrical Panel Repair

Corroded panel connections, tripping circuit breakers, and warm panel covers do not always mean a full replacement. We diagnose with a multimeter and voltage tester, replace burnt lugs or a failed main breaker, and tell you straight whether a repair holds or you are throwing money at a dead panel.

200 Amp Panel Upgrade

The standard for San Mateo homes adding an EV charger, a heat pump, or an ADU. We run the load calculation, coordinate with PG&E on the service drop, and install a 200 amp panel with room for future circuits. Most homeowners ask us whether a 200 amp panel upgrade is worth it in San Mateo CA, and for anything built before 1980, the answer is usually yes.

Fuse Box Replacement

Those old 60 amp fuse boxes in pre-war San Mateo homes cannot carry a modern kitchen, let alone a dryer and AC at once. We retire the fuse box, install a breaker panel with proper grounding wire and conduit, and bring the whole service up to current code. Permitted and inspected.

Subpanel Installation & Upgrades

Detached garages, backyard workshops, and additions often need their own subpanel rather than a bigger main. We size the feeder, run conduit, and land a clean subpanel with its own breakers. Great for EV chargers in the garage or a mini-split in a converted space.

How a panel upgrade actually goes

No mystery, no waiting around. Here is the sequence from your first call to the final inspection, and what you will see at each step.

Call and load calc

You call, we ask a few questions about your home's age and what you are running. We schedule a free estimate, usually same day. On site, we take clamp meter readings and do a proper load calculation to size the panel correctly.

Written quote and permit

You get a written, itemized price before we start. Once you approve, we pull the local building permit with the city. That permit is what gets your install inspected and signed off, and it protects you at resale.

Install day

Power is off for four to eight hours on a typical swap. We mount the new enclosure, land the grounding wire, torque every lug, and label every circuit. We clean up and haul the old panel away.

Inspection and walkthrough

We meet the inspector, walk you through the new panel, and show you which breaker controls what. If anything needs a tweak, we handle it. You get the sign-off and a warranty on our workmanship.

How much does an electrical panel upgrade cost in San Mateo CA?

Most 100 amp panel replacements run $1,850 to $3,200, and a full 200 amp service upgrade runs $3,400 to $6,500 in 2026. Simple repairs start around $385. The range depends on panel size, whether the meter main needs replacing, and how much conduit and grounding work your house needs. We give you a written, itemized price before we start.

Who does electrical panel replacement near me in San Mateo?

We do, and we are local. San Mateo Panel Pros is a state-licensed C-10 electrical contractor working out of San Mateo and covering the whole county. Call (650) 372-5030 and we can usually get an electrician to your door the same day for a free estimate. No trip charge, no runaround.

Do I need an electrical panel upgrade in San Mateo California?

You need one if your panel is 100 amps or less, if breakers trip when you run normal appliances, if the panel cover is warm, or if you are adding an EV charger, heat pump, or ADU. A 60 amp fuse box cannot carry a modern house. We will tell you honestly whether a repair holds or a replacement is the right call.

What is the best electrical panel replacement company in San Mateo?

Look for a licensed C-10 contractor who pulls permits, installs UL listed equipment, and wires to NEC code compliance. We do all three, and we are bonded and insured. Ask any company for their license and whether they pull a permit. If they dodge the permit question, keep looking.

Is a 200 amp panel upgrade worth it in San Mateo CA?

For most San Mateo homes built before 1980, yes. A 200 amp panel gives you room for an EV charger, a heat pump, a tankless water heater, and an ADU without tripping breakers. It also adds resale value and passes inspection cleanly. If your house is small and all-gas, a 100 amp replacement may be enough, and we will say so.
