Cedarburg's National Register historic district along Washington Avenue and the surrounding limestone and cream city brick neighborhoods contain some of the oldest residential properties in Ozaukee County — and some of the oldest electrical systems. Homes built in the late 19th and early 20th century were wired decades before modern safety standards existed. Knob-and-tube wiring from that era, while it was the standard of its time, lacks ground conductors, was not designed for modern load levels, and is now often in a deteriorated state after a century of service.
The Columbia Road Historic District and the neighborhoods north of Cedar Creek also include homes from the 1920s, 1930s, and 1940s with electrical systems that have been modified over generations — sometimes by skilled electricians, sometimes by homeowners who added circuits and outlets without permits. The result can be a wiring system with multiple generations of incompatible approaches running through the same walls.
Burkhardt Heating, Cooling, Plumbing & Electric's licensed electricians serve Cedarburg with specialized experience working in historic homes: knob-and-tube assessment and whole-home rewiring, panel replacement and service upgrades to 200-amp, outlet and switch replacement with period-appropriate or modern finishes, GFCI protection installation in kitchens and bathrooms, and circuit additions for modern loads. We understand how to work in older construction without unnecessary damage to original finishes.
Burkhardt is available 24/7 for electrical emergencies in Cedarburg. All work is performed under permit. GreenSky financing is available for larger rewiring and panel upgrade projects.
EV Charger Installation
As electric vehicles become more common across Southeastern Wisconsin, many homeowners need a Level 2 EV charger installed in their garage. This typically requires a dedicated 240-volt, 50-amp circuit from your electrical panel — and in older homes, a panel upgrade to handle the additional load. Our licensed electricians handle the complete installation: panel assessment, circuit addition, charger mounting, and final inspection. We install all major EV charger brands including ChargePoint, Tesla Wall Connector, JuiceBox, and Grizzl-E.
We install and service panels from Square D, Eaton/Cutler-Hammer, Siemens, and GE. For generators, we're authorized Generac installers — headquartered right here in Waukesha, WI.

My Cedarburg historic home has knob-and-tube wiring. Must I replace it all at once?
Not necessarily. Burkhardt can assess the condition of your knob-and-tube system and prioritize the most critical areas — high-use circuits, circuits in areas with added insulation, and any modified or deteriorated sections. A phased rewiring approach can make the project more financially manageable. Call 414-206-3049 for an assessment.
Does working in a historic Cedarburg home require special permits or procedures for electrical work?
Electrical work in any Cedarburg home requires a permit pulled by the licensed contractor. In historic properties, Burkhardt takes care to work through existing paths where possible and to consult with the homeowner about routing choices that minimize impact on original finishes. All work is inspected and meets current code.
My Cedarburg home's electrical panel is in a difficult location — the basement has limited access. Can you still upgrade it?
Yes. Panel upgrades in historic homes often present access challenges. Burkhardt's electricians assess the situation before providing an estimate and develop an approach that safely executes the work within the constraints of the specific property. We've worked in Cedarburg's older homes for decades.
