How much does a panel upgrade cost in Long Grove, IL?

The cost of electrical panel upgrades in the Long Grove area varies, depending on whether you're replacing a 100-amp service with a 200-amp panel or adding capacity for a new EV charger and home addition at the same time. Homes along the older sections of Old McHenry Road sometimes need a service entrance upgrade alongside the panel swap, which adds to the scope. According to the U.S. Energy Information Administration, the average American home now uses over 10,500 kWh per year, a figure that's climbed steadily as EV charging and home offices pull more load. We quote the full scope upfront so you're not surprised mid-project.

Does Long Grove require a permit for electrical panel replacement?

Yes. Panel replacements, new circuit installs, and wiring upgrades in Long Grove require permits through the Village of Long Grove and are subject to Lake County inspection requirements. Skipping a permit isn't just a code violation; it can flag your home during a real estate transaction and may void a homeowner's insurance claim if unpermitted work contributed to a loss. Our team files the permit on your behalf, coordinates the inspection, and provides you with documentation once the work passes.

What is a subpanel and when do Long Grove homes need one?

A subpanel is a secondary distribution panel fed from your main panel. Long Grove properties with detached garages, outbuildings, pool equipment, or workshops often need one when the main panel is full or when running individual circuits from the house would mean burying hundreds of feet of conduit. A properly installed subpanel with its own dedicated breakers simplifies future expansions and keeps your main panel from being overloaded. We size subpanels to the load they'll carry, not just the minimum needed today.

How does EV charger installation work in Long Grove?

A Level 2 EV charger runs on a dedicated 240V circuit, typically 40 to 50 amps, though some high-draw vehicles and dual-port chargers need 60 amps or more. We start by checking your existing panel capacity and load to confirm the service entrance can support the additional draw without tripping other circuits. Most Long Grove homeowners with a 200-amp panel have room for a Level 2 charger without an upgrade, but homes still on 100-amp service usually need a panel upgrade first. Installation includes running the appropriate wire gauge, mounting the charger, and testing the full circuit before we leave. Learn more about our EV charger installation services by giving us a call today.

Can you install a portable generator hookup at my Long Grove home?

We install generator inlet systems that let you connect a portable generator to your home's electrical panel during a power outage. This setup uses a manual transfer switch or a generator inlet box with an interlock kit to safely route generator power to selected circuits without back-feeding the utility line, which is both illegal and dangerous. Illinois winters and the occasional severe storm that rolls through Lake County make a properly wired generator inlet a practical addition for any home that depends on well pumps, sump pumps, or medical equipment. Understand more about our home generator services by scheduling an appointment with our highly rated local professionals.

What electrical services do you offer beyond panel work in Long Grove?

How do I know if my Long Grove home needs rewiring?

Homes built before 1980 in Long Grove may have aluminum branch wiring or older electrical wiring that's undersized for today's load. Warning signs include breakers that trip repeatedly on the same circuit, outlets that feel warm to the touch, lights that flicker when you run the microwave, or scorch marks around any receptacle or switch plate. These aren't minor annoyances; they're signs that the wiring is being pushed beyond its rated capacity. A licensed electrician can assess your panel, trace problem circuits, and tell you whether you need a targeted repair or a broader rewiring scope.

What's involved in a two-story chandelier installation in Long Grove?

Two-story chandelier installations in high-ceiling foyers require more than just swapping a fixture. The electrical box in the ceiling must be rated for the fixture's weight, which, on large chandeliers, can exceed 150 pounds. If the existing box was installed for a standard ceiling fan or light kit, it likely needs to be replaced with a fan-rated or chandelier-rated fixture box. From there, we assess the wire gauge feeding the circuit, confirm the switch leg is properly sized, and use the appropriate rigging or lift equipment to hang and secure the fixture safely. We handle two-story installations regularly in Long Grove's estate homes and newer builds with dramatic foyer ceilings.

We Provide Electrical Services Long Grove, IL Can Depend On

Most jobs we see in Long Grove fall into a handful of categories: panels that can't keep up with today's load, circuits that were never added for EV chargers or outdoor equipment, and fixtures or fans that need a licensed hand to install safely. Below are the core services we provide across Long Grove and the surrounding Lake County area.

Electrical Panel Upgrades and Repair: We replace undersized or failing panels, upgrade 100-amp services to 200-amp, and add subpanels for detached garages, workshops, and outbuildings. Every panel job includes a load assessment and permit filing.
EV Charger Installation: We install Level 2 chargers on dedicated 240V circuits, sized to your vehicle and panel capacity. If your service entrance needs an upgrade first, we handle that in the same project.
Home Generator Hookups: We wire portable generator inlet systems with manual transfer switches or interlock kits so you can power selected circuits safely during outages.
Lighting Installation: From recessed LED retrofits to two-story chandelier rigging, we handle fixture installation, new circuits, and outdoor lighting runs for Long Grove homes of any size.
Ceiling Fan Installation and Replacement: We install and replace ceiling fans, including bracing for boxes not originally rated for fan weight, and wire new switch legs where needed.
Outlet and Receptacle Installation: GFCI outlets for kitchens, bathrooms, and outdoor locations; 240V appliance outlets; tamper-resistant receptacles; and standard outlet additions throughout the home.
Subpanel Installation: Sized and installed for your actual load, whether you're feeding a pool house, a detached garage, or a large workshop on an acreage lot.
Pool and Hot Tub Circuits: Dedicated circuits for spas, hot tubs, saunas, and pool equipment, wired to code with proper bonding and GFCI protection.
Whole-House Surge Protection: Panel-mounted surge protection devices that clamp voltage spikes before they reach your HVAC system, smart devices, EV charger, and appliances.
Wiring Upgrades: Targeted rewiring for circuits that can't carry today's load, including aluminum branch wiring remediation common in Long Grove homes built before 1980.

Why Choose Mr. Electric of Highland Park for Electrical Work in Long Grove?

Long Grove homes don't all look the same, and their electrical systems don't either. The Kildeer Road corridor has sprawling custom builds on acreage that need subpanels to feed outbuildings and detached garages. Closer to the village center, you'll find homes from the 1970s and 1980s that were never wired for the circuits that modern kitchens, home offices, and EV chargers demand all at once. Our licensed electricians assess your panel capacity, service-entrance amperage, and load distribution before quoting any residential electrical service job. No guessing, no upselling work you don't need.

Flat-Rate Pricing Before the Work Starts

You'll know the full cost before we pick up a tool. Our pricing model is quoted by the job, not the hour, so an upgrade that takes longer than expected doesn't become your problem. That transparency matters in a market where electrical projects routinely run 20 to 40 percent over estimate when billed hourly.

Licensed Electricians Who Know Lake County Code

Illinois electrical work requires permits for most panel, wiring, and dedicated circuit jobs. Lake County and Long Grove's Village Hall each have specific permit and inspection requirements. Our team handles the permitting process, knows which inspectors to work with, and keeps your project compliant with the National Electrical Code. Repairs that look clean but skip inspections can come back as liabilities when you sell.

Mr. Electric has been locally owned and nationally backed since 1994. As part of Neighborly, the largest home services network in the world, we train to the same standards across every location. Your project is covered by the Neighborly Done Right Promise^®: if the work isn't right, we make it right.
