Panel repair or a full upgrade
The panel is Federal Pacific, Zinsco, or Challenger
That is an upgrade, not a repair. Those brands have a documented history of breakers that fail to trip, and many carriers require replacement before they will write or renew a policy. New breakers in the old can do not fix the bus.
One breaker will not stay on, or one lug looks burned
Repair can be enough if the brand is still supported and the bus is clean. A licensed electrician replaces the failed part, checks torque on the rest, and says in writing whether the can itself is still safe. If the bus is pitted or plated away, the answer flips to a full swap.
You want an EV charger, heat pump, or ADU on a 100-amp service
Start with a load calculation, not a panel quote. Some houses have the headroom. Many do not. The electrician you are matched with should show the NEC 220 math before selling a 200-amp service.
The panel face is warm, or you smell plastic at the can
That is an emergency, not a Saturday upgrade. Shut large loads off and call. Heat at the cover means a connection is already failing under load.
