The call I get most often goes something like this. “Hi, how much do you charge to add an outlet?”
And the honest answer, the one that makes people think I’m dodging, is that I don’t know yet. Adding an outlet six feet from an existing one in an unfinished basement is a different job than adding an outlet on an exterior wall in a 1962 ranch with plaster and no attic access above it. Same three words on the phone. Could be a two hundred dollar afternoon or a nine hundred dollar one.
So here’s what I can do instead. Below are honest ballparks for the residential work we do around Naperville in 2026, plus, more usefully, an explanation of what actually pushes a number to the top or the bottom of its range. Read the second part. That’s the part that lets you sanity check whatever quote lands in your inbox, whether it’s ours or somebody else’s.
Everything here is approximate and none of it is a package price. We don’t quote work sight unseen and I’d be a little suspicious of anyone who does.
First, how electricians actually bill, because it varies more than people expect
There are basically three models running around this market and they’re not interchangeable.
Some shops bill time and materials. You pay a service call charge to get a licensed electrician to your door, that usually covers the first hour, and then you’re on the clock. Straightforward, and it’s the fairest structure for diagnostic work where nobody knows what’s wrong yet.
Some bill flat rate per task off a price book. The tech shows up, opens a tablet, and the tablet says an outlet is a fixed number regardless of whether it took twenty minutes or ninety. Homeowners often like this because the number is known upfront. What gets lost is that the price book is built to be profitable on the hard version of the job, so on the easy version you’re overpaying, sometimes a lot.
And then most project work, panels, rewires, EV chargers, remodels, gets quoted as a fixed bid after somebody walks the house. That’s where the real money is and it’s the only category where comparing quotes across companies means anything.
Knowing which model you’re being sold matters more than the individual numbers. A $99 service call from a company on flat rate pricing is a loss leader to get a tech in your house. A $200 service call from a time and materials shop might be the cheaper day.
Service calls and small jobs
For a standard weekday service call in Naperville, expect somewhere in the neighborhood of $150 to $250 to get a licensed electrician out, generally covering the first hour of work. After that you’re looking at roughly $100 to $175 an hour depending on the shop.
Nights, weekends, and true emergency calls run higher, often one and a half to two times the standard rate. If you’re calling at 9pm because half the house is dark, that’s the trade.
Small stuff, the kind of thing that fits inside a single visit:
Swapping an outlet or switch is usually absorbed by the service minimum, so call it $150 to $300 depending on how many you’re doing at once. Doing eight of them in one trip costs far less per outlet than doing one, which is why I always tell people to make a list before they call.
A GFCI receptacle, installed, tends to land around $200 to $350. Adding a brand new outlet on an existing circuit is more like $250 to $450, and that’s the job where the range is genuinely honest rather than padded, because fishing wire through a finished wall is unpredictable.
Ceiling fans depend entirely on what’s already in the ceiling. On an existing fan-rated box, roughly $250 to $500. If there’s no box, or there’s a box that was never rated to hold a fan and somebody hung one there anyway, which I see constantly, you’re adding bracing and you’re closer to $400 to $800.
Recessed lighting retrofits run something like $200 to $400 per fixture, and again drop per unit when you do a whole room at once.
A dedicated circuit for a specific appliance, a window unit, a freezer, a shop tool, generally falls between $400 and $900 depending on the distance from the panel and what’s between here and there.
The bigger projects
This is where the ranges widen and where getting somebody to actually look at the house stops being optional.
Panel work is the big one. Replacing an electrical panel at the same amperage typically runs in the $1,800 to $3,500 area. A genuine service upgrade, moving from 100 amps to 200, is more like $2,500 to $5,000 in Naperville once you account for the permit, the inspection, and coordinating the shutdown with the utility. If the meter socket, the service entrance cable, or the mast needs replacing too, add to it.
Level 2 EV charger installs are all over the place, anywhere from about $800 for a short clean run in an attached garage to $2,500 and up when the panel is on the opposite corner of the house or doesn’t have capacity to spare. We wrote separately about when the panel upgrade is genuinely required versus when people get talked into one they don’t need.
Whole home surge protection, installed at the panel, is usually $400 to $800. For what it does I think it’s one of the better dollar-for-dollar purchases in this whole list.
A whole-house rewire is the top of the market and I won’t pretend otherwise. Depending on square footage, era, and how much plaster is involved, these land somewhere between $12,000 and $30,000, occasionally higher on large older homes. Nobody quotes that off a phone call.
Standby generator work, the electrical portion, generally starts around $5,000 and climbs based on transfer switch type and how many circuits you’re backing up.
What actually moves the number
Here’s the part I’d want to read if I were you.
Access decides more than anything else. An unfinished basement below and an accessible attic above means we can get almost anywhere in the house without opening a wall. A slab foundation with a finished basement ceiling and no attic clearance means every run is a fishing job, and fishing jobs are slow and occasionally destructive. Two houses on the same street can differ by double for identical scope.
Then there’s what we find. Older Naperville houses, particularly from the fifties and sixties and the 1965 to 1973 aluminum era, tend to have surprises behind the drywall. Cloth insulated wiring that crumbles the moment you touch it. Ungrounded boxes. Junction boxes buried behind finished walls with no access panel, which is a code violation we then have to resolve before we can sign off on our own work. I can’t price any of that from the driveway, and any electrician who tells you otherwise is guessing and building the guess into the number.
Drywall repair is the other one people forget. Most electrical contractors, us included, cut clean and patch nothing. The number you get from an electrician usually stops at the hole. Budget separately for patching and painting or ask specifically whether it’s included, because assuming either way has burned people.
Panel brand matters more than it should. If you have a Federal Pacific Stab-Lok or a Zinsco, we’re generally not adding breakers to it, we’re recommending replacement, and the “cheap” job you called about just became a panel conversation. That feels like a bait and switch when you hear it and it isn’t. Those panels have a documented history of breakers that fail to trip. Our post on spotting an outdated panel covers how to identify what you’ve got.
And scope creep, mostly the good kind. Half the jobs that grow, grow because we opened something and found a real problem. The other half grow because the homeowner says “well, while you’re here” and honestly that’s the efficient time to do it. Batching work is the single best way to lower your cost per item.
Two Naperville costs nobody puts in their pricing guide
This is where Naperville differs from the generic national cost articles you’ve probably already read.
A permit is required prior to beginning any electrical work inside the city limits. Not major work. Any electrical work, and that includes low voltage wiring above 25 volts or 50 watts, so security system and data cabling too. You can read the city’s own page on the electrical permit requirement if you want it from the source.
The second one is stricter than most towns. Naperville requires that the work be performed by a state-licensed electrical contractor who is also registered as an Electrical Contractor with the City of Naperville specifically. State license alone isn’t enough here. A fair number of outfits working the western suburbs skip that registration, and if yours isn’t registered, your permit is a problem and your job may not pass.
That has a direct effect on your quote. A properly permitted job carries the permit fee, the contractor’s time applying through the Civic Access portal, and the scheduling around inspection, which has to be booked in advance rather than same day. A quote that’s meaningfully cheaper than everyone else’s is often cheaper because none of that is in it. Which is fine right up until you sell the house and a buyer’s inspector asks about unpermitted work. We covered what inspectors actually flag in what an electrical inspection checks.
One more detail worth confirming for your specific job. The city’s electrical permit page currently cites the 2017 National Electrical Code, but Naperville adopted updated code references under Ordinance 26-010 for plans submitted on or after April 1, 2026. Which edition governs your work depends on when you submit, so it’s worth a call to Building Permits at (630) 420-6100, option 2, before anyone orders material.
How to get a number you can actually rely on
Make a list before you call. Every flickering fixture, every dead outlet, every “we’ve always wanted a light there.” One visit covering nine items costs dramatically less than nine visits, and it lets whoever comes out see patterns rather than symptoms.
Ask which billing model you’re on. Time and materials, flat rate book, or fixed bid. Ask it directly, it’s a normal question.
Ask whether the quote includes the permit, the inspection, and drywall patching. Those three omissions account for most of the gap between quotes that look wildly different.
Ask for the state license number and confirm the company is registered with the City of Naperville. Anyone legitimate will answer that in about four seconds.
Then, for anything above a couple hundred dollars, get it in writing before work starts. Not because most people in this trade are dishonest, they aren’t, but because memory is unreliable and written scope prevents the argument.
Common questions about electrician pricing here
What’s a typical service call fee for an electrician in Naperville? Generally somewhere between $150 and $250 for a standard weekday visit, which usually covers the first hour of work. After-hours and emergency calls typically run one and a half to two times that.
Why do quotes for the same job vary so much? Usually because they’re not actually the same job. Differences come from access, whether the permit and inspection are included, whether drywall repair is included, and what each electrician found or assumed about your existing wiring. Ask each one what’s excluded rather than what’s included.
Is a permit really required for small electrical work in Naperville? Yes. The city requires a permit prior to beginning any electrical work within city limits, including low voltage wiring above 25 volts or 50 watts. The work also has to be done by a state-licensed contractor registered with the City of Naperville.
Roughly what does a panel upgrade cost in Naperville? A same-amperage panel replacement is typically in the $1,800 to $3,500 range, while a true 100 to 200 amp service upgrade generally runs $2,500 to $5,000 once permit, inspection, and utility coordination are accounted for. Meter or service entrance work adds to that.
Do you give prices over the phone? For straightforward small work we’ll give you a realistic range on the phone. For anything involving the panel, a rewire, or a project bid, we come out and look first, then put a written number in your hands. Sight-unseen quotes tend to become change orders later.
Is it cheaper to bundle several small jobs into one visit? Considerably, yes. Most of the cost of a small job is getting a licensed electrician to your house. Nine items in one trip costs far less than the same nine spread across several visits.
Do you charge for an estimate? Project estimates are free and come in writing with no obligation. Diagnostic work, meaning we’re troubleshooting to find out what’s wrong, is billable, because that’s the job rather than a sales visit.
