Electrician servicing Naperville and St. Charles, IL. Top rated Electrical Company.
We’re an owner-operated electrical shop serving Naperville, St. Charles, and the surrounding suburbs since 2003 — licensed, bonded, and insured. One thing most folks don’t know: Illinois has no statewide residential electrical code. Each town adopts and amends its own, so what’s fine in one suburb can fail inspection in the next. We work under these local codes every day and know what each town’s inspectors look for. When you need a Naperville electrician, you want straight answers and work done right the first time — that’s what we do.
Electrical work isn’t the place to gamble. A loose connection behind a wall can smolder for months before it turns into a fire. We don’t rush jobs or cut corners — we test everything before we leave, and we stand behind the work. If something we installed isn’t right, call us and we’ll make it right.

I needed to have a neutral wire installed in order to use a smart switch to control the outside lights. I also needed to install a security camera outside to replace an old light fixture. After a phone call to explain what I needed, and setting a schedule for the work, Darius from Reliant was there on-time, listened to what I needed to get done, and explained the work at every step. I am extremely happy with the service and the professional people at Reliant, and will definitely recommend them to everyone I know.Posted on Google![]()

I had a wonderful experience with this company. The electrician was so knowledgeable and kind. I honestly didn’t know what to expect- I needed all of my can lighting replaced with LED so I took the advice from them and was so pleased. The lights are beautiful. I also had him replace some of my fixtures as well. The electrician was very nice and professional. Highly recommend. If I could give 6 stars I would!Posted on Google![]()

Absolutely top drawer service from Reliant on our spa install. They were incredibly responsive and punctual and answered all of my questions. I had incomplete information for them on what parts I had already and they went ahead and ordered everything I might have needed to make sure they could complete the work in one day and I was only charged for what I ended up needing. Pricing was fair and I felt it was a white glove experience. Highly recommend.Posted on Google![]()

Electrical Repairs
Outlets that quit, ceiling fans that wobble, breakers that trip for no clear reason — most electrical problems start small. The trick is finding the actual cause instead of just swapping parts. We do electrical repairs in Naperville and the surrounding areas, and we trace problems to the source so they stay fixed — and your home is safer when we’re done.
Electrical Troubleshooting
Flickering lights, a dead outlet, a breaker you keep resetting — folks learn to live with this stuff until it gets worse. Don’t. We’ll track down the fault and fix it for real. One thing we correct on almost every service call: unmarked panels. The code (Article 408.4) requires every circuit to have a legible, permanent description — because a labeled panel means no guessing in the dark when a breaker trips.
Electrical Inspections
An electrical safety inspection finds what you can’t see — loose connections, overheated breakers, outlets that were never wired right. Whether your house is from the 1930s or last year, it’s worth knowing what’s behind the walls. We also check your GFCI and AFCI protection. The short version: GFCIs protect people from shock (NEC Article 210.8), and AFCIs guard against fires started by arcing (NEC Article 210.12). They do different jobs, and both save lives.
Electric Car Charger for Home
We install Level 2 home EV chargers every week, and we build them to last — correctly sized circuits, clean conduit runs, no shortcuts. If you’re on the fence about cost: ComEd’s 2026 residential EV program offers up to $2,500 per household toward a Level 2 charger and installation. Programs change, so check what’s currently available — but it can cover a good chunk of the job. Learn more about our Electric Car Charger Installation services.
