One licensed crew for the small fix and the big job — no subcontractors, no handoffs.
100A to 200A service, fuse box replacements, and sub-panels for additions. Permit pulled and inspection handled.
Breakers that keep tripping, dead outlets, flickering lights, burning smells. We find the cause, not just the symptom.
Level 2 chargers on a dedicated circuit, mounted where you actually park. Rebate paperwork included.
Whole-home automatic standby with transfer switch, plus annual service so it starts the night you need it.
Recessed lighting, under-cabinet, ceiling fans, exterior and landscape. Dimmers that don't buzz.
Kitchens, basements, garages and additions wired from rough-in to final trim, on the builder's schedule.
We are not a franchise or a call centre with a truck. The person who quotes your job is the person who shows up to do it.

A few from the last month, all within fifteen minutes of the shop.



Ray opened Prairie Line in 2004 after fifteen years wiring new construction across Will County. The idea was simple: show up when you say you will, quote the job honestly, and answer the phone yourself.
Twenty years later it is a five-electrician shop and Ray still runs calls. Every electrician on the truck is licensed, background-checked, and has been here at least four years — you will start recognising them.

“Called at 9pm with half the house dark. Ray answered himself, talked me through shutting off the right breaker, and was here at 7 the next morning. Found a failed neutral in twenty minutes.”Dana R.Bolingbrook
“Three electricians quoted our panel upgrade. Prairie Line was the only one who pulled the cover off and looked before giving a number. Price never moved.”Marcus T.Naperville
“They wired our whole basement remodel and coordinated with the inspector so we never had to be home. Left the place cleaner than they found it.”Priya S.Woodridge
