Panel Upgrades in Sammamish, WA
Modern homes pull more power than 100-amp panels were built for. We upgrade to 200-amp service with clean, labeled, inspection-ready work.
A lot of Plateau homes built from the 1980s onward are now old enough for their first panel replacement, especially in households adding an EV charger or heat pump. We pull the permit and handle the inspection so the upgrade closes out clean.
Symptoms we see every week
- Breakers trip when the AC and oven run together
- Still on a 100-amp or fuse-based panel
- Adding an EV charger, heat pump, or ADU
- Panel is unlabelled or has doubled-up breakers
