Panel upgrades and breaker box replacement in Windsor, California
If your Windsor home still has a fuse box, a Zinsco or Federal Pacific panel, or a breaker box with double-tapped lugs and no free slots, an upgrade is the single highest-value electrical project you can do. It is also the prerequisite for almost every other upgrade in Sonoma County homes.

What affects panel upgrade pricing in Windsor
| Service size and panel location | A straight swap in the same spot costs far less than relocating the service. |
|---|---|
| Meter and mast condition | Rusted masts, buried service and damaged meter bases add work at the utility side. |
| Grounding and bonding | Older homes often need ground rods and a proper water bond added. |
| Permit and utility coordination | Included in the quote, but the schedule depends on the local inspector and utility. |

Recent Windsor feedback
Panel had no room left and we wanted an EV charger. Got a straight answer, a flat number, and the whole thing done in a day. The new labels alone were worth it.
Marisol R.Windsor, CAOur restaurant cannot close, so they did the panel work overnight. Walked in the next morning to everything working and the floor cleaner than we left it.
Nadia F.Windsor, CAWe rewired in stages so we could keep living here. They planned the access holes where the patcher could actually fix them, which I did not expect.
Ellen and Ray M.Windsor, CAElectrical Panel Upgrade in Windsor — questions we get asked
How much does an electrical panel upgrade cost in Windsor?
In Windsor and the wider Sonoma County market, a straightforward 200 amp upgrade usually lands in the low-to-mid four figures, with meter relocation, long service runs and mast work pushing it higher. You get one flat number after we look at the service entrance, not a range.
Do I need a permit for a panel upgrade in Windsor?
Panel and service work is permitted work in California. We pull it, meet the inspector, and handle the utility coordination so the job closes out properly.
How long does a panel upgrade take?
Most Windsor residential upgrades are a one-day job. Power is off for part of that day while the utility disconnects and reconnects, and we schedule that window with you in advance.
Do I really need 200 amps?
If you are adding EV charging, electric heat, a hot tub or an ADU, yes — and it is far cheaper to do it once. If your loads are modest and the panel is simply old, a same-size replacement may be all you need. We tell you which case you are in.
Will you fix the labeling?
Every panel we touch leaves with each breaker mapped and labeled. It takes twenty minutes and saves the next electrician an hour.
