What drives electrical panel upgrade cost
- Target amperage: Going from 100 to 200 amps (or higher) means a bigger panel and often a new service entrance.
- Panel location & access: A cramped or far-from-the-meter location makes the job slower and pricier.
- Service entrance: Upgrading the mast, meter, and utility connection adds cost beyond the panel itself.
- Code corrections: Older homes often need grounding, bonding, or circuit fixes to pass inspection.
- Permits & labor: An electrical permit, utility coordination, and licensed-electrician rates drive much of the total.
Seattle cost factors
Seattle's wet climate makes roofing, siding, and drainage especially important, and its strong economy keeps labor well above the national average. Washington permitting and energy codes add to the cost of most home projects.
