Residential Electrical Services in Naperville, IL
From routine repairs to full-home rewiring projects, we cover the complete range of residential electrical needs for Naperville properties. Naperville’s housing stock spans five decades of construction – each era brings its own electrical challenges. Here’s how we help keep your home running safely and up to current Illinois code:
Electrical Repairs
Tripped breakers, dead outlets, and flickering lights are common in Naperville homes built in the 1980s and 1990s when electrical loads were a fraction of today’s. We diagnose the root cause fast — loose connections, overloaded circuits, or aging receptacles — and fix it the same day wherever possible.
Whole-House Rewiring
Older Naperville neighborhoods like Naper Settlement area and Country Lakes still have homes running on original aluminum branch wiring or knob-and-tube systems. Both are fire risks and insurance liabilities. We replace the entire system with modern copper wiring, upgrading capacity without tearing your home apart.
Lighting Installations
From recessed lighting in Naperville basement finishes to landscape lighting along DuPage River trail-facing yards, we plan the layout, handle the wiring, and make sure every fixture works exactly as intended. We match lighting levels to each room’s use and your personal preferences.
Smart Home Systems
Naperville’s newer subdivisions near 95th Street are full of homes adding smart thermostats, automated lighting, and security systems. We handle the electrical side — dedicated circuits, neutral wire runs, and load balancing — so your smart devices work reliably without tripping breakers or causing interference.
Panel Upgrades
Many Naperville homes built before 2000 have 100-amp or 150-amp panels that struggle with today’s loads: EV chargers, heat pumps, home offices, and high-efficiency appliances all draw more power than older panels were sized for. We upgrade to 200-amp service, add surge protection, and pull all required DuPage County permits.
Safety Inspections
Buying a home in Naperville’s competitive market often means skipping a deep electrical inspection. We perform thorough walkthroughs — checking panel condition, grounding, GFCI coverage, and wire insulation — and give you a written report of what needs attention now versus what can wait.

Naperville’s housing stock spans five decades of construction, and each era comes with its own electrical problems. Homes built in the 1970s and early 1980s in neighborhoods like Hobson West or Country Lakes often have aluminum branch wiring, which expands and contracts differently than copper and can loosen at outlets and switches over time — creating a fire risk. Homes from the late 1980s and 1990s frequently have undersized 100-amp panels that struggle with today’s loads. Newer construction near Route 59 and 95th Street tends to need additional circuits for EV chargers and home office setups that weren’t part of the original plan. Flickering lights, warm outlets, frequent breaker trips, and a burning smell near the panel are all signs you should call a licensed electrician before the problem grows.
Before we arrive, clear the area around your electrical panel and any outlets or switches we’ll be working on. Let us know in advance about specific concerns — buzzing switches, outlets that feel warm, or a breaker that keeps tripping for the same circuit. If you have pets or young children, keeping them out of the work zone helps us stay safe and focused. For larger projects like whole-house rewiring or panel upgrades, we’ll walk through the scope with you before starting and let you know if any circuits will be temporarily off. We pull all required Naperville/DuPage County permits before work begins on permitted jobs, so you’re covered if you ever sell the home.
Yes — most electrical work beyond simple device replacements requires a permit from the City of Naperville Building & Zoning Department. This includes panel upgrades, new circuit installations, EV charger wiring, whole-house rewiring, and any work that opens walls or changes the electrical system’s capacity. We handle the permit application and coordinate the inspection on your behalf. Unpermitted electrical work can cause issues when you sell the home and may void your homeowner’s insurance in the event of a claim.
If your home was built before 2000 and still has a 100-amp or 150-amp panel, it’s likely undersized for today’s electrical demands. Clear signs include breakers that trip frequently, lights that dim when appliances start, or a panel that has no open slots for new circuits. If you’re planning to add an EV charger, a heat pump, or a home office with dedicated circuits, a panel assessment should be the first step. We check load calculations before recommending an upgrade so you know exactly what your home needs.
Aluminum branch wiring — common in homes built between 1965 and 1973, including parts of older Naperville neighborhoods — is a recognized fire hazard when not properly maintained. It’s not automatically an emergency, but it does require attention. The most common fix is copalum crimping or pigtailing at every outlet, switch, and fixture — connecting a short copper wire to the aluminum so the device sees only copper. Full rewiring is the most comprehensive solution. We assess the condition of your aluminum wiring and give you honest options at different price points.
Yes — Level 2 EV charger installation is one of our most requested services in Naperville, particularly in newer subdivisions near Freedom Commons and the Route 59 corridor where EV ownership is growing fast. A Level 2 charger requires a dedicated 240-volt, 50-amp circuit run from your panel to the garage. We check your panel’s available capacity first — if an upgrade is needed, we handle that as part of the same project. All EV charger installations are permitted and inspected per Naperville code.
Whole-house rewiring replaces every branch circuit in your home with new copper wiring sized for today’s loads. In Naperville homes, this typically means working through finished walls with minimal drywall damage — we use fish tape and drill techniques to route wire without opening every wall. The project includes replacing all outlets, switches, and fixtures, updating the panel, and testing every circuit before the inspection. Most whole-house rewires in a 2,500–3,500 sq ft Naperville home take three to five days. You’ll be without power to specific circuits during work but rarely lose whole-home power for more than a few hours.
ComEd is the electric utility serving Naperville (except the city-owned Naperville Electric Utility area in the downtown core). For panel upgrades or service entrance work, we coordinate with ComEd to schedule a meter pull before we start and meter reconnection after the inspection passes. ComEd typically schedules these within a few business days. We handle the coordination so you don’t have to navigate the utility process yourself.
Yes — current Illinois electrical code requires GFCI protection in kitchens, bathrooms, garages, unfinished basements, outdoor outlets, and within six feet of any sink. Many older Naperville homes have standard outlets in these locations that never got upgraded. We replace them with GFCI receptacles or install a GFCI breaker to protect the full circuit — whichever approach makes more sense for your home’s layout. This is also a common item flagged during home sales inspections in Naperville.
Absolutely. Home offices with multiple monitors, docking stations, and laser printers draw more power than a standard 15-amp shared circuit was designed to handle. We run dedicated 20-amp circuits from your panel to the office, add the outlets where you need them, and make sure the circuits are labeled correctly in the panel. If your panel is full, we add a subpanel or upgrade as needed. Most home office circuit additions in Naperville are completed in a single day.
A full residential electrical inspection for a typical Naperville home (2,000–3,500 sq ft) takes two to three hours. We check the panel for proper breaker sizing, grounding, and available capacity; test every outlet and switch for correct wiring and GFCI/AFCI coverage; inspect visible wiring in the basement, attic, and garage; and evaluate the service entrance condition. You receive a written summary of findings with items ranked by priority — safety-critical issues versus code upgrades versus cosmetic concerns.
Arc-fault circuit interrupter (AFCI) breakers detect dangerous arcing in wiring — the kind caused by a nail through a wire or a worn insulation spot inside a wall — and shut the circuit off before a fire starts. Current Illinois electrical code requires AFCI protection for bedrooms, living rooms, hallways, and most other living spaces in new construction and renovations. Many Naperville homes built before 2014 don’t have them. While retrofitting AFCI breakers isn’t always required unless you’re doing permitted renovation work, it’s one of the highest-value safety upgrades available for an older home.
