Before the work
Cedarburg questions.
Do you do electrical work on Cedarburg historic-district homes?
Yes — Cedarburg has over 200 preserved historic buildings, many with original knob-and-tube or early cloth-insulated wiring. We specialize in updating those systems while respecting original finishes: rerouting circuits to avoid plaster damage, installing AFCI/GFCI protection where required by code, and coordinating with the city's Historic Preservation Commission when fixtures or service entrances are visible from the street.
How long does a panel upgrade take in a 1900s Cedarburg home?
For a straightforward 100A → 200A upgrade in a Cedarburg historic-district home, plan on a one-day install plus a separate inspection visit. Older homes sometimes have grounding or service-entrance issues we discover once the panel is open — if so, we explain the options before any extra work, so you never see a surprise on the bill.
Where do permits get pulled for Cedarburg?
Through the City of Cedarburg Building Inspection office on Washington Avenue. We handle the application, fees, and inspection scheduling for you on every permitted job — homeowners don't need to drive downtown.
Do you install EV chargers in Cedarburg?
Yes. Most Cedarburg installs are Level 2 (240V) chargers in attached garages. We size the new circuit, run the wiring (usually under 30 feet from the panel), install the charger, and test load on the existing service. About half a day; we quote it after seeing the panel.
Are you licensed and insured?
Yes. Owner Dennis Couillard holds Wisconsin Residential Master Electrician License #1293757, and Couillard Electric LLC holds Electrical Contractor License #1325885. We carry full general-liability and workers' comp insurance. We pull permits and schedule inspections on every job that needs them.
Do you offer free estimates?
Yes — every estimate is free. Call (262) 618-2851 or use the Free Estimate form to schedule. For most residential work we can come out within 1–3 business days.
