The Big Picture
Where this fits in your home's electrical system
Power enters at the service mast, passes through the meter into the panel, and branches into every circuit in the house. Here's the whole path — and where this service fits.
- Service mast & meter Where utility power lands on your home — the weatherhead, riser, and meter base.
- Main electrical panel The heart of the system: breakers that protect every circuit in the house.
- Whole-home surge protection Installs at the panel to shield electronics from utility spikes and nearby strikes.
- Wiring & circuits You're here The branch circuits behind your walls — the runs that age out in older Seattle homes.
- Outlets & switches Every connection point — including GFCI/AFCI protection where code requires it.
- Lighting Fixtures, recessed cans, and the dimmers and controls that run them.
- Ceiling & ventilation fans Ceiling, exhaust, and whole-house attic fans — comfort and moisture control.
- Smoke & CO detectors Hardwired, interconnected alarms on every level — the code standard for safety.
- EV charger A dedicated 240V circuit from the panel to Level 2 charging in your garage.
- Backup generator Standby power with a transfer switch, sized to what you want to keep running.

Knob & Tube Replacement FAQs
Why replace knob-and-tube wiring?
It's ungrounded, brittle with age, can't safely handle modern loads, and is often a fire risk. Many insurers also won't cover homes that still have it.
Can it be replaced without gutting my house?
Often, yes — we access and replace wiring with the least disruption possible and patch cleanly. We'll assess your home and set clear expectations.
