Jumping from 100A to 200A costs significantly more than a simple panel swap at the same amperage due to heavier wiring and meter base changes.
Panels in tight closets, basements, or exterior walls may require additional labor to access and meet modern clearance codes.
Old aluminum wiring or cloth-insulated wire may need replacement to safely connect to a new panel, increasing scope.
Some jurisdictions require whole-house AFCI/GFCI protection or grounding upgrades when replacing a panel, adding circuits and cost.
The utility must disconnect and reconnect power — scheduling and any required meter base upgrades add time and potential fees.
The Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
