Panel Upgrades
100A-to-200A service upgrades, subpanels, meter bases, and service masts — the backbone work that makes everything else possible.
If your home still runs on a 100A panel — or a crowded, breaker-stuffed 150A — an upgrade to 200A service gives you the headroom for an EV charger, a heat pump, an induction range, or a workshop subpanel without juggling loads.
We handle the whole chain: utility coordination with Duke Energy or Dominion, meter base and service mast replacement where needed, the new panel, clean labeling, and the inspection. We also replace recalled and known-problem panels (Federal Pacific, Zinsco) that insurers increasingly flag.

How a panel upgrade works, step by step.
From your photos to the power coming back on — usually one working day on site.
Send your photos
Fill out our free panel upgrade assessment with photos of your meter and panel.
Get your estimate
We send you a written estimate based on your photos.
Approve the estimate
Review it and approve when you're ready.
Place your deposit
A deposit locks in your spot on the schedule.
Permit & inspection
We request and pull the permit, and the inspection is set for the same day as the work.
Schedule the power cut
Together with you, we schedule the utility disconnect and reconnect — a 2–4 hour window in the morning.
Old panel out, new panel in
Once the power is disconnected, our crew removes the old panel and assembles and wires the new one.
Inspection & power on
The inspector comes at the end of the day. Once the job is approved, the power company is notified to restore power.
Final payment & review
We send the final amount owed. If you're happy with the work, we'd appreciate a 5-star Google review.
Common questions
What is the panel upgrade process?
Nine steps: send photos through our assessment, get an estimate, approve it, place a deposit, we pull the permit (inspection is set for the day of the work), we schedule the utility disconnect/reconnect in a 2–4 hour morning window, the crew swaps the panel, the inspector approves it at the end of the day and the power company restores power, then final payment. See the full process.
How do I know if my panel needs upgrading?
Common signs: a 100A main, fuses instead of breakers, no room for new circuits, breakers that trip when two big appliances run, or plans to add an EV charger or heat pump. We confirm with a load calculation, not guesswork.
How long is the power off during a panel upgrade?
Typically most of one working day. We coordinate the utility disconnect and reconnect so the outage window is as short as possible, and we tell you the schedule in advance.
Will a panel upgrade pass inspection in my county?
Yes — that's the point. We pull the permit with your county or city AHJ and the work is inspected before the job is closed out.
