Switch Installation And Repair fixes the control point between a wall switch and a light or load. The work can include switch replacement, wire repair, box support, GFCI testing, and new switch installation. Miami has older bungalows, Art Deco buildings, apartments, and new high-rise units. South Beach properties may have tight walls and older switch boxes, while Coral Gables homes may have larger remodel scopes. Local permit needs depend on the work and the authority having control. A risky shortcut is replacing a switch without tracing each wire. We use a circuit tracer and voltage test before removal. We document the wire layout, test the finished switch, and note any work that needs a permit or follow-up.
