Most panel upgrades happen for one of three reasons: the existing service is too small (a 60A or 100A panel, or an old fuse box), the panel is unsafe or failing, or you're adding a big new load like an EV charger, hot tub or air conditioner.
An upgrade to a modern 100A or 200A breaker panel gives you the capacity and safety today's homes need — and it's often required by insurers on older properties.
Every home is different, which is why we always quote by the project after a free estimate. The main factors are: the new service size (100A vs 200A), whether the meter base and mast need replacing, the condition of the existing wiring, and whether an ESA permit and inspection are required (they usually are — and we handle it).
Consider an upgrade if your breakers trip often, the panel feels warm or buzzes, you still have a fuse box, your lights flicker, or you're planning to add an EV charger or major appliance. A quick, free inspection will tell you for sure.
