Siepker Electric Services operates from Lakeshore Drive in Lake Elsinore, handling residential electrical work across the region — service calls, panel upgrades, EV charger installations, recessed lighting, ceiling fans, generator hookups, and emergency repair. The scope spans both routine maintenance and larger projects like solar tie-ins and smart home wiring, with work split between existing homes needing updates and new construction. Demand for this range is strongest in two scenarios: newer tract homes in south Temecula and Murrieta where EV chargers are a standard addition and modern loads push older panels to capacity, and aging Lake Elsinore and Hemet properties where electrical systems haven't kept pace with air conditioning and appliance upgrades. For homeowners weighing DIY solutions against licensed work, Siepker handles the jobs that require permits and inspection — panel work, dedicated circuits, anything that touches the main service or ties to the grid. Same-day emergency repair and scheduled upgrades both come through; lead times tighten in summer when cooling demand spikes and panel failures become urgent.
