Professional electricians in Greenfield, CA — 37+ years experience, NEC compliant, veteran-owned and operated.
Comprehensive electrical services for homes and businesses — licensed, insured, and backed by our workmanship guarantee.
EV chargers draw significant power and require proper circuit protection. Our licensed electricians ensure your installation meets NEC code, manufacturer specs, and local requirements.
We run Cat6 or coax cable from each camera location to your DVR or NVR, mount cameras at optimal angles, install weatherproof junction boxes, and power everything through a centralized system.
Aluminum wiring expands and contracts more than copper, causing loose connections that overheat and arc. Insurance companies increasingly refuse to cover aluminum-wired homes. Our licensed electricians eliminate the risk permanently.
Ceiling fans involve heavy fixtures and live wiring above your head. Our licensed electricians ensure every connection is secure, every mount is load-rated, and every fan runs safely.
Recessed lights create a clean, modern look while flooding your rooms with even illumination. LED recessed fixtures also cut your lighting energy use by up to 75 percent.
Outdoor wiring must withstand moisture, temperature swings, and soil contact. Our electricians use UL-listed wet-rated fixtures, GFCI-protected circuits, and proper burial depths to ensure lasting safety.
We disconnect the utility feed, swap your outdated panel for a modern load center, re-land every circuit on correctly rated breakers, and coordinate the final inspection with your municipality.
Our electricians locate the nearest power source, run new wiring through your walls, install the outlet box, and test the circuit to confirm safe, reliable operation.
Keep your home powered through any outage with a professionally installed backup generator. Enjoy uninterrupted comfort and security when the grid goes down.
Upgrade your home with new light fixtures that transform the look and feel of every room. Professional installation ensures proper support, clean wiring, and the right dimming compatibility.
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 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.
We test the suspect breaker with calibrated equipment, check for loose bus connections and signs of arcing, replace the faulty breaker with a matching UL-listed unit, and load-test the circuit.
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.
We install a dedicated 240V circuit from your panel to the equipment pad, wire the GFCI disconnect within sight of the unit, bond all metal components, and verify ground fault protection.
We examine your panel, wiring, outlets, switches, grounding system, and GFCI protection room by room, then deliver a detailed written report with findings and recommended corrections.
Electrical installations done without permits or by unlicensed workers put your family at risk and can void your insurance. Our licensed electricians deliver code-compliant, inspected work on every job.
Commercial electrical work requires strict code compliance, proper load calculations, and coordination with inspectors and general contractors. Our licensed commercial electricians deliver permitted, inspected, and insured work on every project.
Homes built before 1980 often have degraded insulation, undersized circuits, or knob-and-tube wiring that insurance companies flag as unacceptable. Our licensed electricians bring your wiring up to current NEC standards.
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.
We install smart switches, dimmers, and outlets that work with your existing Wi-Fi network, set up automation routines, and ensure every device has the neutral wire and load capacity it requires.
We install a Type 2 surge protection device directly at your electrical panel, wire it to a dedicated double-pole breaker, and verify the grounding system that makes it effective.
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.

"Needed a 240-volt outlet for our EV charger. JJC Electric came out, assessed the panel capacity, ran the wire through the attic to the garage, and had it done in half a day. Clean work, fair price, no mess."
