Reliable Residential Electrical Work
Residential Electrical Services
Outlets
Outlet work in older Naperville homes is rarely just “swap the receptacle.” Two-prong outlets need grounding, kitchen and bathroom circuits need GFCI protection per NEC, bedroom circuits need AFCI protection, and all new outlets in living spaces have to be tamper-resistant under current code. We install and replace outlets for remodels, kitchen and bath upgrades, garage and outdoor circuits, and any 2-prong-to-3-prong conversion that needs a proper ground path — not just a cheater plug.
Light Switches
Light switch work covers more than dead toggles. We install three-way and four-way switches for stairs and long hallways, dimmer switches rated for LED loads, smart switches that play nicely with your existing Wi-Fi, occupancy sensors for closets and pantries, and the neutral-wire upgrades that smart switches actually need to work. If a switch is buzzing, getting warm, or only working sometimes, that’s a wiring issue — not a switch issue — and we trace it before swapping parts.
Ceiling Fans
Ceiling fan installs come down to one question the listing photo doesn’t show you: is the box rated for fan support? Most original light-fixture boxes aren’t. We install fan-rated boxes, run new wiring for switched-fan circuits, install separate switches for fan and light, and handle vaulted-ceiling fans where the downrod, brace, and box all need attention. Bedroom and family-room fan installs are bread-and-butter; we also do covered-porch and three-season-room fans rated for damp locations.
Lighting
Residential lighting is half design, half wiring. Recessed can-light and wafer-light retrofits, kitchen under-cabinet lighting, bathroom vanity and shower-rated fixtures, basement lighting on occupancy sensors, exterior soffit and landscape lighting, and chandelier installs for dining rooms and two-story foyers. We size dimmers correctly for LED loads, run circuits that won’t overload when you add more lights later, and handle the trickier installs — vaulted ceilings, scuttle access, finished basements where we can’t just open a wall.
Circuit Breakers
A breaker that keeps tripping is telling you something — the question is whether it’s the breaker, the circuit, or the load. We diagnose nuisance trips, replace failed breakers, install AFCI breakers for bedroom and living-area circuits, install GFCI breakers for kitchens, baths, garages, and exteriors, and replace failed Federal Pacific or Zinsco breakers found in many older Naperville homes. If your panel is full, we install tandem breakers where the panel is rated for them or recommend a sub-panel rather than overloading slots.
Whole-House Rewiring
Whole-house rewiring usually comes up for Naperville homeowners with knob-and-tube, cloth-insulated, or aluminum branch-circuit wiring — all common in pre-1950 and mid-century housing stock around downtown Naperville and the older near-suburbs. We rewire one room at a time when you’re remodeling, full-house when you’re opening walls anyway, and we handle the insurance-driven rewires that come up after a home inspection flags knob-and-tube during a sale. Permit, plan, ComEd coordination if a service upgrade is part of it, and rough-in and final inspections are all on us.
Electrical Panels
Most Naperville homes built before the mid-1990s came with 100-amp service, and most homes now run AC, EV chargers, induction ranges, and home offices that the original panel was never sized for. We upgrade 100-amp services to 200-amp (occasionally 400-amp for larger custom homes), replace failed Federal Pacific and Zinsco panels, swap aging Murray and Challenger panels, and coordinate with ComEd for the meter pull and service-drop work that has to happen on the same day. Permit and final inspection through the City of Naperville’s building department are part of the job, not an afterthought.
Smoke Detectors
Illinois requires hardwired, interconnected smoke detectors with battery backup in every bedroom, outside every sleep area, and on every level of the home. We install and replace hardwired smokes during remodels, add CO/smoke combination detectors where code requires them, and run interconnect wiring in older homes that were originally built with battery-only smokes. Selling your house? We handle the rewire and inspection sign-off needed for the buyer’s home inspection.
EV Chargers
Home EV charger installs depend on three things: where the car parks, where the panel is, and whether the panel can handle a 40–60 amp dedicated circuit. We install Level 2 chargers (Tesla Wall Connector, ChargePoint, Wallbox, JuiceBox, and hardwired NEMA 14-50 outlets), pull permits with the City of Naperville, and handle the panel upgrade if your existing service can’t support the load. ComEd’s EV-friendly time-of-use rate plans pair well with a hardwired install on its own dedicated circuit.
New Construction
New residential construction is where electrical and the rest of the trades have to dance together. We work with custom-home builders and GCs across Naperville on rough-in (after framing, before drywall), trim-out (after paint), service entrance and meter coordination with ComEd, and the final inspection walk with the City of Naperville. Smart-home pre-wire — Cat6, structured cabling, distributed audio, and smart-switch neutrals — is best handled at rough-in, not as a retrofit.
Electrical Remodeling & Renovation
Remodel electrical is where surprises live. Walls open, you find knob-and-tube spliced into Romex, GFCI missing in a kitchen that was last redone in 1986, and a panel with no room for the new circuits the remodel needs. We run new circuits for kitchen islands, second-floor laundry, basement finishes, and primary-bedroom additions, plus the panel additions or sub-panels to make the new load fit. We coordinate inspection windows with your GC’s drywall and finish schedule so the project doesn’t stall.
Emergency Electrical Services
When you need an emergency electrician in Naperville, the call usually starts with one of three things: half the house has lost power, a breaker won’t reset, or there’s a burning smell from an outlet or panel. We respond fast across Naperville and the surrounding suburbs because none of those wait until morning. Tripped main, failed breaker, blown service drop, or arcing outlet — we diagnose the cause before just resetting the breaker, because resetting a breaker that tripped for a reason is how electrical fires start.

Working with Naperville’s Permit & Inspection Process
Most major residential electrical work in Naperville requires a permit pulled through the City of Naperville’s Building Department — panel upgrades, service changes, whole-house rewires, EV chargers, additions, and significant remodels. Cob Services LLC pulls permits in our own contractor name when scope requires it, submits load calculations the city expects, and schedules rough-in and final inspections so they don’t slow your project. We also coordinate with ComEd for service upgrades and meter relocations, the part of a project that quietly adds days if it’s not started early.
Residential Electrical Company Naperville
Hiring a contractor can feel like walking onto a used car lot. Working with a local team is supposed to save you money over time, not bleed you on “upgrades” you never asked for.
A lot of the bigger electrical companies aren’t training their techs to be electricians anymore. They’re training them to be salesmen. The push for upsells and add-ons has more to do with a corporate sales target than with your house. We don’t run that way at Cob Services LLC. We recommend the work that’s actually needed to keep your home safe and functional, and we leave it at that. It’s also part of why our customers rank us among the best electricians in Naperville.
Our electricians don’t get a bonus for selling you a panel you don’t need. If a $200 repair will do, we’ll quote the $200 repair, even when there’s a $4,000 version of the same fix sitting in the catalog. That’s the whole job — find the smallest fix that actually solves the problem.
We’re not the cheapest electrician in town and we don’t try to be. We’re the one that gives you a straight answer, charges you a fair price, and does work that doesn’t need to be redone in three years.
