Services / Panels, Breakers & Service Upgrades

Panels, Breakers & Service Upgrades

Replace aging panels, add sub-panels, increase service capacity, and add surge protection. Neat, labeled, and inspection-ready every time.

Why upgrade your panel

Older panels and undersized services are one of the most common reasons we get called. As homes add EV chargers, heat pumps, induction ranges, and home offices, the demand grows past what the original service was designed for.

We help you size correctly the first time, work with the utility on service changes, and pull the right permits so the upgrade is documented and safe.

  • Properly sized service for your real load
  • Labeled, organized panel directory
  • Modern surge and arc-fault protection
  • Permitted and inspected where required
