Electrical Panel Upgrades

More amperage, more breaker slots, and a panel that meets current code.

A 100-amp panel from the 1970s wasn’t built for a house running an EV charger, a heat pump, and a home office at the same time. A panel upgrade adds capacity and breaker slots, and brings the service into line with current code, permitted and inspected, not just swapped.

  • Load calculation first, so the new panel size is based on your actual and planned electrical demand, not a guess
  • Permit pulled and inspection scheduled before the old panel comes down, not after
  • Main breaker, meter base, and grounding brought up to current code as part of the same job
  • Labeling every circuit clearly when the new panel goes in, so the breaker box is actually usable
  • Power outage during the swap kept to a single, scheduled window, not an open-ended one

Common questions

How is an electrical quote calculated?

Most quotes come from the scope of the job (which circuits, how much access is needed) plus permit and inspection fees where they apply. Diagnostic and repair calls are usually priced from a service call fee plus time once the cause is found; larger jobs like panel upgrades or rewiring get a firm, written price after a walkthrough.

Do you charge a service call fee?

Yes, most repair and diagnostic visits start with a service call fee that covers the visit and diagnosis; it typically applies toward the repair if you move forward. Ask for the exact number when you book.

Do I need a permit for this work?

Panel upgrades, rewiring, new circuits, and generator installs almost always need a permit; smaller repairs like replacing a switch or outlet usually don’t. We tell you upfront whether your specific job needs one, and we pull it ourselves rather than skip it.

Will the power be off during the work?

Only on the circuits being worked on, whenever that’s possible. A panel upgrade or full rewire does require the main power off for part of the job; we schedule that window with you in advance rather than surprise you with it.

How long does a typical job take?

A repair or diagnostic visit is usually same-day. A panel upgrade typically takes a few hours to a full day depending on inspection scheduling. A whole-house rewire can run from several days to a couple of weeks depending on home size and wall access.

Are you licensed to do electrical work?

Yes. Electrical work requires a state electrical license separate from a general contractor’s license, and we carry ours. See our Licensing & Insurance page for our license number and details, or ask us directly before you book.

What’s the difference between licensed and insured?

Licensed means the state has verified we’re qualified to do electrical work; insured means there’s liability coverage if something goes wrong on the job. Both matter, and we carry both. Ask for documentation of either before you book if you want to see it directly.

Do you pull permits and handle inspections?

Yes, on any job that requires one. We schedule the inspection, meet the inspector, and walk you through what passed. A job that skips the permit can’t be verified later, which becomes a real problem at resale or with insurance.

How do I know if I need a panel upgrade?

Common signs: your panel is still rated 60–100 amps, breakers trip when you run multiple appliances at once, you’re adding a big new load like an EV charger or heat pump, or your panel still uses fuses instead of breakers. A load calculation during a free estimate will tell you for certain.

How long does a panel upgrade take?

The physical swap is usually a few hours to a full day. The power to the house is off only during that window, which we schedule with you in advance. Permit and inspection scheduling around it can add a few days on either side.

Will I lose power during a panel upgrade?

Yes, for the duration of the swap itself, since the main panel has to be de-energized to work on it safely. We schedule this window with you so it’s not a surprise, and it’s typically a matter of hours, not days.

Does my panel need an upgrade for an EV charger?

Not always, it depends on how much spare capacity your panel already has. We check that with a load calculation before quoting the install, so you know upfront whether it’s a straightforward circuit or a bigger job.

Will rewiring damage my walls?

Some opening and patching of drywall or plaster is unavoidable to reach existing wiring, we coordinate patching as part of the job rather than leaving it as a surprise. We’ll walk you through exactly what’s being opened before we start.
