Electrical panel upgrades and replacement
Replacing an old or undersized panel, upgrading service from 100 to 200 amps, and breaker work. Load calculation first, permit and utility coordination handled, and inspected before we call it done.
- Typical residential upgrade
- One day, 4 to 8 hours
- Permit and inspection
- Handled by us
Does your house actually need one?
Not every house does, and we’ll say so if yours doesn’t. An upgrade makes sense when the panel can’t safely carry what you’re asking of it, when there’s no room for the circuits you want to add, or when the equipment has reached the end of its life.
The answer comes from a load calculation, not a guess: what’s connected now, what you plan to add, and what the service can carry. That’s the first thing we do.

Panel and service installations
How the job runs
Assessment and load calculation
We look at the panel, the service and the house, and work out what it needs to carry now and later.
Written price and permit
You get the price in writing. Once you say go, we pull the permit and arrange the disconnect and reconnect with your utility.
Installation day
Most 100A to 200A residential upgrades take one day, usually four to eight hours. Power is off for part of it, and we tell you when.
Inspection and reconnection
The work is inspected, power is restored, and every circuit is labeled.
Common questions
How long does a panel upgrade take?
Most residential upgrades from 100A to 200A are done in a single day, usually four to eight hours. You’ll be without power for part of that. We arrange permits in advance so nothing holds up the day itself.
Do I need a bigger panel for an EV charger?
Not always. A load calculation tells us whether your current service can carry a Level 2 charger. Sometimes a smaller charger circuit or a load-management device avoids an upgrade. Sometimes the panel is genuinely at capacity. We’ll show you the numbers either way.
Will I need a permit?
Yes. Panel replacements and service upgrades need a permit and an inspection, and we handle both as part of the job. Be wary of anyone offering to skip it: unpermitted work can void your homeowner’s insurance and cause problems when you sell.
Can my existing EV charger move to a new panel?
Usually, yes. We check the circuit requirements during the estimate and tell you if anything needs to change. If you’re adding a charger and upgrading the panel, we plan both as one project, which saves time and money.
