What our electrical panel upgrade service covers in Mill Valley
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 Mill Valley 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
Breaker kept tripping and two other companies just kept resetting it. Phase Three found a nicked cable behind a bathroom wall in about forty minutes.
Smart switches I bought would not work in my old house. Turned out there was no neutral in the boxes. They pulled neutrals to six switches in a day and everything works now.
Storm took out our service mast. They tarped it, coordinated with the utility, and had us reconnected the next morning.

Why Mill Valley 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 Mill Valley 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 Mill Valley
How much does an electrical panel upgrade cost in Mill Valley?
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 Mill Valley 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 Mill Valley 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 Mill Valley?
Yes. A service change is permitted and inspected work in Mill Valley, 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 Mill Valley 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 Mill Valley, call (833) 652-8933 rather than waiting.
