Trusted electrical contractor in Mercer Island, Washington — panel upgrades, generator installs, EV chargers, and 24/7 emergency repair.
From panel upgrades to EV charger installation, our licensed electricians handle every residential and commercial electrical need.
Control your lights, thermostats, locks, and more from your phone or voice assistant. Smart home wiring creates a connected, energy-efficient home that simplifies your daily routine.

We install hardwired smoke detectors in every required location, interconnect them so all units sound together, add battery backup, and test the full system before we leave.
Breakers that trip repeatedly are warning you of a serious problem. Forcing them back on risks fire or electrocution. Our electricians safely diagnose whether the issue is the breaker, the wiring, or an overload.
We mount your Ring doorbell at the optimal height, run low-voltage wiring from your existing doorbell transformer, and configure the app so you are up and running in one visit.
Ignoring electrical problems lets them get worse. Loose connections, arcing wires, and overloaded circuits cause thousands of house fires each year. Our licensed team fixes issues safely, the first time.
Electrical problems often hide behind walls where they quietly worsen. Our licensed electricians follow a systematic diagnostic process to find issues before they become fire hazards or safety threats.

CO detector placement matters as much as having one. Installed too high, too low, or too far from sources, they may not alarm in time. Our electricians follow manufacturer and code guidelines precisely.
We map out fixture placement for optimal light coverage, cut precise ceiling openings, run new circuits as needed, and install IC-rated housings that are safe for insulated ceilings.
Heavy chandeliers, track lighting, and pendant fixtures require properly rated electrical boxes and secure mounting. Our electricians ensure every installation is safe, level, and wired correctly.
Overloaded outlets and daisy-chained power strips are leading causes of electrical fires. We install dedicated circuits with proper grounding and tamper-resistant receptacles to keep your family safe.
