Before the work
Mequon questions.
Do you handle large-lot Mequon properties with detached garages or barns?
Yes — that's one of our specialties. Mequon's larger lots (often an acre or more) frequently mean detached structures that need their own subpanels, underground feeder runs, exterior lighting, or EV charger installs in a detached garage. We size feeders correctly, trench properly, and bond/ground per code so detached structures pass inspection the first time.
How much does a panel upgrade cost in Mequon?
Mequon homes built in the 1980s–90s commonly have Federal Pacific or Zinsco panels that are now considered fire hazards — replacing those is a high-priority job. We give a firm quote after seeing the existing service, mast, and grounding.
Can you install whole-home generators in Mequon?
Yes — Generac, Kohler, and Cummins, properly sized for the home (typically 18–26 kW for Mequon homes). We coordinate with the city for the gas line connection inspection and electrical permit. Most installs take 1–2 days; commissioning and load test takes another half-day after the gas inspector signs off.
Do you do landscape and outdoor lighting in Mequon?
Yes. With the larger lots in Mequon, low-voltage landscape lighting and outdoor receptacles for holiday lighting are common. We size the transformer, run direct-burial cable, and install fixtures so they don't overload the circuit.
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.
