What Affects Your Cost
Several factors determine the final price of your panel upgrade. Here's what we evaluate during your free site assessment.
Service Size
Upgrading from 100A to 200A costs more than a same-size panel replacement. Larger services require heavier wire and upgraded meter equipment.
Home Age & Wiring
Older homes may need additional work to bring wiring up to code. Knob-and-tube or aluminum wiring may require updates.
Meter Base Condition
If your meter base is corroded, undersized, or doesn't meet current utility requirements, it may need replacement too.
Code Requirements
Current NEC code requires arc-fault (AFCI) and ground-fault (GFCI) breakers in many locations, adding to material costs.
