Working in Waukesha County
Couillard Electric LLC extends our professional electrical services throughout Waukesha County — one of Wisconsin's fastest-growing and most affluent counties. From the established neighborhoods of Waukesha and Brookfield to the lakefront properties of Pewaukee and Oconomowoc, we provide residential electrical services built on quality workmanship.
Waukesha County homeowners have high expectations and we deliver. The larger homes in Brookfield and Delafield often need 200-400 amp panel upgrades to support modern amenities — EV chargers, hot tubs, home theaters, and workshop circuits. Pewaukee and Oconomowoc lakefront properties frequently need outdoor electrical work including dock lighting, landscape illumination, and weatherproof outlets. We understand the permitting process across Waukesha County's municipalities.
