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.
We handle tenant improvements, lighting retrofits, panel upgrades, dedicated equipment circuits, emergency power systems, and code compliance upgrades for commercial and industrial spaces.
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.

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.
