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.
EV chargers draw significant power and require proper circuit protection. Our licensed electricians ensure your installation meets NEC code, manufacturer specs, and local requirements.
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.
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.
Smart devices need proper wiring to function reliably. Many older homes lack neutral wires in switch boxes, causing flickering or device failure. Our electricians verify and upgrade wiring so your smart home works right.
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.
Keep your home powered through any outage with a professionally installed backup generator. Enjoy uninterrupted comfort and security when the grid goes down.

We remove old fixtures, upgrade the electrical box if needed, connect and mount the new fixture securely, and test dimmer compatibility so your lights perform exactly as expected.
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.
