Electrical Panel & Service Upgrades

When a new EV charger, kitchen, or set of circuits asks more of an older panel than it can give, we plan a proper upgrade. Every recommendation starts with a load calculation. We handle 100A to 200A service upgrades, panel replacements, permits, and inspections.

When a panel upgrade is the right next step

Many homes in Oak Park and the nearby suburbs still have 100A service, or a full panel with no room for a 240V EV circuit or a remodel. We check the existing service, explain what the load calculation shows, and quote a clear path — a panel replacement, a service upgrade, or, when it is enough, a more limited circuit change.

  • Load calculations before we recommend work
  • 100A to 200A service upgrades
  • Panel replacements and added capacity for EV, kitchens, and additions
  • Permits and inspections handled

Wall restoration is part of the job

If the panel sits in a finished room or the upgrade means opening a wall, we patch plaster or drywall and paint so the area is restored to like-new.

How we restore walls

A finished job includes the clean-up

We clean up our own mess

Drop cloths and floor protection go down before we start. When we open walls, we contain dust as we work. When the electrical work — and any plaster, drywall, or paint — is finished, we vacuum, wipe down the floors, haul debris away, and leave the room as clean as we found it, or cleaner.

  • Drop cloths and floor protection
  • Dust containment when we open walls
  • Vacuuming and floors wiped down
  • Debris hauled away

Questions about this service

Will you upgrade my panel as part of an EV charger install?

Yes, when the load check shows it is needed. The written quote covers the upgrade and the charger circuit together.

Do you take care of the wall around the panel?

Yes. If we open a finished wall or the work disturbs the finish around the panel, we restore the plaster or drywall and paint.
