Working in Ozaukee County
Couillard Electric LLC has served Southeast Wisconsin since 2013, including Ozaukee County homeowners. From the historic homes of downtown Cedarburg to the lakefront estates of Mequon and the waterfront properties of Port Washington, we understand the unique electrical challenges of this area. Many Cedarburg homes feature knob-and-tube wiring that needs updating, while Mequon's larger properties often require heavy-duty electrical systems for detached buildings, pools, and EV chargers.
Ozaukee County is home to some of Wisconsin's most beautiful and historic properties. The covered bridge district in Cedarburg, the Milwaukee River corridor through Grafton, and the Lake Michigan bluffs of Port Washington all present unique electrical considerations. We've worked on historic renovations in Cedarburg that required careful wiring around century-old construction and modern smart-home installations in Mequon. Our home base is Random Lake.
