Before the work
Grafton questions.
Do you serve newer Grafton subdivisions?
Yes — much of Grafton's housing is post-1990 construction with proper service panels and grounding. The most common calls we get there are EV charger installs (the high-density family neighborhoods around Wisconsin Avenue and Falls Road have a lot of two-EV households) and panel upgrades to 200A when families add a hot tub, generator, or finished basement.
Can you install a Tesla Wall Connector at a Grafton home?
Yes. We install Tesla, ChargePoint, JuiceBox, Wallbox, and most other Level 2 chargers. We pull the village permit, mount the unit, run the dedicated 240V circuit, and test the install against the manufacturer's commissioning checklist. we quote it after seeing the panel.
How fast can you respond to an emergency in Grafton?
Our business hours are Monday through Friday, 8:00 AM to 4:00 PM CT. Urgent problems get same-day attention whenever the schedule allows. For life-threatening situations like fire, smoke, or downed lines, call 911 first.
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.
