Your Electrical Problems Fixed Right the First Time

You flip a switch and nothing happens. Or worse—you smell something burning near your breaker box. These aren’t problems you can ignore, and they’re not problems you should try to fix yourself.

When your electrical system acts up, you need someone who can diagnose the real issue fast and fix it correctly. Not a band-aid. Not a “let’s see if this works.” A proper repair that keeps your family safe and your power flowing.

That’s what we do as a residential and commercial electrical company that’s been doing this work for 25 years. You get someone who’s seen the problem before, knows exactly what’s causing it, and has the tools and knowledge to handle it without creating new issues down the line.

Your lights work. Your outlets are safe. Your breaker box isn’t overloaded. And you’re not lying awake wondering if something’s going to short out in the middle of the night.

Jimco Electric has been handling electrical repairs and emergencies in Wilmington, IL for over two decades. We’re not a franchise that showed up last year.

We’re licensed, bonded, and insured because that’s the baseline. But what matters more is that we specialize in residential electrical work—the kind of urgent repairs that happen when your panel starts buzzing or your kitchen outlets stop working right before dinner.

We also offer discounts for military, first responders, seniors, teachers, and students. Not as a marketing gimmick, but because we live here too.

Here's What Happens When You Call Us

You call or message us with the problem. We ask a few questions to understand what’s going on—whether it’s an emergency or something that can be scheduled.

If it’s urgent, we move fast. For scheduled work, we show up on time and start with a real diagnostic. That means checking your panel, testing circuits, looking at wiring condition, and figuring out what’s actually wrong—not just what seems wrong.

Once we know the issue, we explain it in plain terms. What needs to be fixed, why it needs to be fixed, and what it’s going to cost. No surprises, no upselling you on things you don’t need.

Then we do the work. Whether that’s replacing a faulty breaker, upgrading your service panel, adding a new circuit for an EV charger, or rewiring an outlet that’s been sparking. We test everything before we leave, clean up the work area, and make sure you understand what we did.

You’re left with electrical systems that work the way they should. And if something comes up later, you’ve got our number.

What We Actually Fix in Wilmington Homes

Most of our work falls into a few categories. Emergency repairs—things like power outages, burning smells, or breakers that keep tripping. Panel upgrades for homes still running on outdated 100-amp or 200-amp systems that can’t handle modern electrical loads. Circuit additions when you need power somewhere new, like a garage, basement, or EV charging station.

We also handle flickering lights, which are usually a sign of loose wiring or an overloaded circuit. Faulty outlets that don’t hold plugs or feel warm to the touch. Service changes when your main electrical service needs to be upgraded to meet current code or support more power.

Illinois homes—especially older ones built before the 1970s—often have aluminum wiring or outdated panels that weren’t designed for how much electricity we use today. Air conditioning, electric heating, computers, appliances, chargers. It all adds up. And when your system can’t keep up, that’s when problems start.

We also do electrical safety inspections. These aren’t just code compliance checks. We’re looking for fire hazards, grounding issues, overloaded circuits, and anything else that could put your home or family at risk.

How do I know if my electrical panel needs to be upgraded?

Your breakers trip frequently, even when you’re not running anything unusual. That’s the most common sign. It means your panel can’t handle the electrical load your home is pulling.

Other signs include lights dimming when you turn on an appliance, outlets that feel warm, a panel that’s warm to the touch, or visible rust and corrosion inside the box. If your home was built before 1990 and still has the original panel, there’s a good chance it’s undersized for today’s electrical demands.

Most older homes in Wilmington were built with 100-amp or 200-amp service. That was fine when homes had fewer devices. But now, between HVAC systems, kitchen appliances, computers, TVs, and EV chargers, you’re pulling a lot more power. Upgrading to a 200-amp or 400-amp panel gives you the capacity you actually need and reduces fire risk from overloaded circuits.

Turn off the main breaker if you can do it safely, and call us immediately. A burning smell near your panel usually means a wire is overheating, a breaker is failing, or there’s a loose connection arcing inside the box.

Don’t ignore it. Electrical fires often start inside panels when connections deteriorate or circuits get overloaded. If you see scorch marks, melted plastic, or smoke, get everyone out of the house and call 911 first, then call us.

Even if the smell is faint, it’s worth having someone look at it. Electrical problems don’t fix themselves, and they tend to get worse. A quick inspection can catch a serious issue before it becomes a fire hazard. We’ve seen too many close calls that could’ve been prevented with an earlier service call.

Yes. Most EV chargers need a dedicated 240-volt circuit, which means running new wiring from your panel to wherever you’re installing the charger—usually a garage or driveway.

We start by doing a load calculation to make sure your existing panel can handle the additional draw. If it can’t, we’ll recommend a panel upgrade first. Trying to run a high-draw appliance like an EV charger on an already-maxed-out panel is a recipe for tripped breakers and potential fire hazards.

Once we confirm your panel has capacity, we install the circuit, mount the charging station, and test everything to make sure it’s pulling the right voltage and working safely. The whole process usually takes a few hours to a full day depending on how far the run is and whether we need to upgrade your service first.

It usually means the appliance is pulling more power than the circuit was designed to handle, or there’s a loose connection somewhere in the line. When a high-draw appliance like an air conditioner, space heater, or microwave kicks on, it creates a temporary voltage drop that causes lights on the same circuit to dim or flicker.

If it’s happening on one circuit, the fix is often adding a dedicated circuit for that appliance so it’s not sharing power with your lights. If it’s happening throughout the house, that’s a bigger issue—possibly an undersized panel, a problem with your main service line, or a loose connection at the meter or panel.

Flickering lights aren’t just annoying. They’re a sign your electrical system is struggling. And when systems struggle, components wear out faster and fire risk goes up. We can diagnose the exact cause with a few tests and give you a clear fix.

It depends entirely on what needs to be done. A simple outlet repair might run a couple hundred dollars. A full panel upgrade can range from $1,500 to $4,000 depending on the size of the panel and how much rewiring is involved.

Emergency calls, after-hours work, and jobs that require pulling permits or upgrading service lines will cost more. But we give you a clear estimate before we start any work, so you know exactly what you’re paying for.

We also offer discounts for military, first responders, seniors, teachers, new customers, and students. If you qualify, let us know when you call. We’d rather give you a fair price up front than surprise you with a bill that doesn’t match what we talked about.

Yes. We handle emergency calls 24/7 because electrical problems don’t wait for business hours. If your power goes out, you smell burning, or a breaker keeps tripping and won’t reset, those are situations that need immediate attention.

When you call, we’ll ask what’s happening so we can prioritize based on safety. If it’s a fire hazard or a total loss of power, we move fast. If it’s something that can wait a few hours, we’ll schedule you as soon as possible.

We’ve been doing this for 25 years, so we’ve handled just about every kind of electrical emergency you can imagine. Power outages during storms, panels that fail in the middle of winter, outlets that start sparking at night. We know how stressful it is when something goes wrong with your electrical system, and we show up ready to fix it.
