Commercial Electricians in Downers Grove, IL
Cob Services LLC has spent the last 10 years wiring, fixing, and maintaining commercial buildings around Downers Grove. When your lights start flickering or a breaker keeps tripping, you don’t want a sales pitch. You want a licensed electrician to show up and get your power back so you can run your business.
We’re a local commercial electrical contractor, not a call center. Our licensed team treats your building the way we’d treat our own: we show up when we say we will, work around your hours so your doors stay open, and explain what we did in plain English. If you’ve been searching for a commercial electrician near you in Downers Grove, this is what we do all day.
Licensed & insured electricians serving Downers Grove businesses
Every job runs through licensed, insured electricians working under Illinois license #26-00032356. That matters for commercial work, where a bad connection isn’t just an inconvenience — it’s a fire risk and a failed inspection. We pull permits when the job calls for one and leave you with work that passes.
Commercial electrical services we provide in Downers Grove
One licensed team for the whole building, instead of a different contractor for every job. Here’s the commercial electrical work we handle for Downers Grove businesses.
Electrical panel upgrades
Old panels run hot, trip under load, and can’t handle the equipment you’ve added over the years. We upgrade commercial panels and replace failing breakers so your building carries the load it has now.
Commercial electrical maintenance
We’d rather find a loose connection on a scheduled visit than get the panic call Friday at noon. Regular maintenance keeps small faults from becoming shutdowns, and we keep records so you know what was checked and when.
Electrical installation service
New equipment, a buildout, power where there wasn’t any before — we install it to code and stay out of your way. That includes dedicated circuits for machinery and appliances that need their own line.
Commercial wiring updates & rewiring
Aluminum wiring, overloaded runs, a building that’s been added onto one too many times — we update or fully rewire commercial spaces so the wiring matches how you actually use the place.
EV charging stations
More Downers Grove businesses are adding chargers for staff and customers. We size and install commercial EV charging so it works with your existing service instead of overloading it.
Custom & LED lighting
We design the layout, swap the fixtures, and set the dimmers and sensors so they actually work. LED cuts your power bill and gets you off the ladder changing dead bulbs every few months.
Outlet grounding & replacement
Worn or ungrounded outlets are a code problem and a fire risk. We ground and replace commercial outlets so your equipment is protected and you pass inspection.
Ceiling fans
For warehouses, restaurants, and open floors, the right fans move air and cut cooling costs. We mount and wire them safely at commercial heights.
Remodeling & renovations
Reconfiguring a retail floor or office? We handle the electrical side of a commercial remodel: moving circuits, adding lighting, bringing older spaces up to code.
New construction
Building from the ground up, we work off your plans and wire the whole project on schedule with the other trades, from the service entrance to the last outlet.
Emergency electrical service
When the power’s out, business stops. We come out and get you running again.

Commercial LED lighting in Downers Grove
If you’re still on old bulbs, you’re paying for it twice — once on the power bill and again every time someone climbs a ladder to change one. Switching to LED is one of the fastest ways to cut both. We handle the whole job: design the layout, swap the fixtures, and set the dimmers so the light suits the space instead of blasting it like a doctor’s office. You get a lower bill right away, fixtures that last years, and wiring done right, not just plugged in.
Commercial energy audits
Most owners know the bill is too high but not where the power’s going. We do a walk-through of your building — lighting, HVAC, heavy machinery — and find what’s eating the budget. Then you get a short, plain plan: what to fix first for the biggest savings, where a few sensors or timers pay for themselves, and which old equipment is quietly costing you. No giant spreadsheet, just lower overhead.
