Common questions
How much is a panel upgrade in Rockwall?
Most 200A upgrades run $2,800–$4,500 depending on service entry, grounding, and meter location.
Do I need a 200A panel?
You do if you're adding an EV charger, heat pump, hot tub, or ADU. And if your panel has a Federal Pacific, Zinsco, or Challenger label — replace it regardless.
Will the power be out all day?
6–8 hours typically. We schedule for a workday and you're back up before dinner.
