What our electrical panel upgrade service covers in San Mateo
100 to 200 amp service upgrades, breaker box and fuse box replacement, sub panels and full service changes.
100 to 200 amp service upgrades
The standard move for a San Mateo home adding air conditioning, an EV charger, a heat pump or a kitchen remodel. New panel, new meter main, new grounding.
Fuse box replacement
Screw-in fuses cannot protect modern branch circuits or handle today's loads. We swap the whole assembly for a breaker panel.
Obsolete panel replacement
Federal Pacific Stab-Lok, Zinsco and Challenger panels have known breaker failure histories. Replacement is the only real fix.
Sub panels
Feeding a detached garage, workshop, ADU or addition without overloading the main. Sized for what you will actually plug in.
Permits and utility coordination
A service change means a permit, an inspection and a power drop from the utility. We schedule all three so you are not chasing anyone.
Whole-home surge protection
A panel-mounted surge device is the cheapest insurance you can buy for a house full of electronics. Installed at the same visit.
How it works
Four steps, no surprises. This is the same process whether it is a single outlet or a full service upgrade.
You call
We ask enough to know whether this is urgent. If it is, we dispatch instead of booking you in for next week.
We diagnose
We find the actual cause before quoting. Replacing parts until something works is expensive for you.
You get one price
Flat, agreed before any work starts. If the scope changes we stop and re-quote rather than adding it later.
We finish clean
Work tested, circuits labelled, site cleaned. You should only notice the thing that now works.

Recent feedback
They found that our flickering lights were a loose lug in the meter base, not the fixtures we had already replaced twice. Wish we had called them first.
Our breaker box was so old parts were not made anymore. They replaced it and labelled every circuit properly, which nobody had ever done.
Recessed lighting in the living room and kitchen. They marked the whole ceiling layout first and let me move a couple before cutting. That small thing made the result.

Why San Mateo homeowners and businesses choose us for electrical panel upgrade
The difference between a good electrical job and a bad one is rarely visible on the day. It shows up two years later, in a connection that worked loose, a circuit that was never quite sized right, or a repair that treated the symptom instead of the cause.
We work in San Mateo with that in mind. Diagnosis comes before quoting. The price is flat and agreed before we start, so a job that turns out harder than expected is our problem rather than a line on your invoice. And if the honest answer is that you need less work than you expected, that is what we will tell you.

Electrical Panel Upgrade questions from San Mateo
How much does an electrical panel upgrade cost in San Mateo?
Price depends on the amperage you need, whether the meter main and service entrance are being replaced, how the run to the utility is configured and what the panel location requires. We quote the whole job as one flat number for San Mateo homes before any work starts, so call (833) 652-8933 and we will price your exact setup.
How long does a panel upgrade take?
Most residential service upgrades in San Mateo are a single day on site, with power off for a portion of it. Add time if the utility needs to schedule the disconnect and reconnect, which we book in advance so it lines up with our crew.
Do I need a permit for a panel upgrade in San Mateo?
Yes. A service change is permitted and inspected work in San Mateo, and the utility will not reconnect without a signed inspection. We pull the permit, meet the inspector and coordinate the reconnect as part of the job.
Do I really need 200 amps?
Not always. A modest San Mateo home with gas heat and cooking may be fine at 100 or 125 amps. But if you are adding an EV charger, electric range, heat pump or a large air conditioner, 200 amps stops you paying twice. We run the load calculation before recommending anything.
How do I know my panel is failing?
Warmth on the panel cover, a buzzing or crackling sound, a burning smell, breakers that trip with normal load, rust inside the enclosure or scorch marks on the bus are all end-of-life signs. If you see any of these in San Mateo, call (833) 652-8933 rather than waiting.
