If your Fremont home still runs on a 100-amp panel — or an old fuse box — you’ve probably wondered what it costs to upgrade. Here’s a straight answer, along with what actually drives the price.
The short answer
For most Fremont homes, replacing or upgrading an electrical panel typically runs between $1,800 and $4,500, with a straightforward 100A-to-200A upgrade usually landing in the middle of that range. Bigger jobs — a panel relocation, a full service upgrade with new meter equipment, or added circuits — can run higher.
Every home is different, so the only way to get an exact number is a quick on-site look. But the ranges below will help you set expectations.
What drives the cost
| Factor | Effect on price |
|---|---|
| Amperage (100A → 200A) | Higher capacity, more materials and labor |
| Panel location | Relocating a panel adds significant labor |
| Wiring condition | Old or unsafe wiring may need correcting first |
| Permits & inspection | Required for panel work in Fremont — we handle this |
| Surge protection / add-ons | Whole-home surge protection is a common add-on |
Signs it’s time to upgrade
- Breakers that trip regularly
- A fuse box instead of a breaker panel
- No room to add circuits for an EV charger or remodel
- A panel from a brand with known safety recalls
- Burning smells, warm panel covers, or discoloration (call right away)
If you’re planning an EV charger installation or a kitchen remodel, a panel upgrade is often the first step — modern demand simply needs more capacity.
Is a panel upgrade worth it?
For most homeowners, yes. A modern 200-amp panel improves safety, ends nuisance tripping, and future-proofs your home for EVs, heat pumps, and electronics. It can also be a selling point at resale.
