FAQ
Cob Services LLC is fully registered and bonded in every municipality where we work. We carry comprehensive General Liability and Worker’s Compensation insurance to protect both our team and your property. We’re happy to provide copies of our certificates of insurance and local registrations before we kick off your project.
Each client project is bid on an individual basis, dependent on the type and scope of work. We can provide both hourly and project-based estimates which are free of charge. Some standard projects can be estimated over the phone while complex projects may require a site visit and additional research to provide a more accurate quote.
The electrical trade is one of a select few specialty trades that requires extensive licensing and continuing education. Due to the level of the risk involved from improperly installed components, we recommend you trust a licensed and insured professional to do your electrical work, rather than attempting it yourself. One thing you can do to reduce costs and get the job done quicker is to make sure your home is ready for electrical work to be done prior to the arrival of our crew. Working in an environment that is free and clear of clutter allows us to be as efficient as possible with your time and ours.
The short answer is yes—if you’re doing more than just swapping out a light cover, you’re almost certainly going to need a permit. In Illinois, we don’t have a single state agency that handles this; instead, everything is run through your local city hall or county building department. Because every town has its own quirks and local codes, we take that headache off your plate by handling the paperwork and coordinating with the local inspectors ourselves. We make sure we’re properly registered in your specific municipality so the job stays totally above board. Just keep in mind that permit fees aren’t one-size-fits-all—your local building department sets those prices based on the scale of the project and where you’re located.

Electric Vehicle Charger Installations
As the demand for electric vehicles continues to surge, Cob Services LLC is proud to offer expert, ICC-certified EV charger installations for leading brands like Tesla, Ford, and Siemens. With more manufacturers pivoting to high-tech electric models, our team helps you navigate this transition by determining if your home is equipped for Level 1 or Level 2 charging. To guarantee the highest safety standards, our Licensed Electricians will perform a detailed load calculation on your main electrical panel, identifying if your current system is sufficient or if a professional service panel upgrade is necessary to power your new vehicle reliably.
Swimming Pool Outlet Installation
At Cob Services LLC, we know that a backyard pool is where your family makes memories, but it only stays fun if it’s safe. Dealing with electricity near water is a serious job that requires more than just following a manual—it requires a licensed pro who treats your home’s safety like their own. We handle everything from installing rugged, weather-rated pump outlets to the complex “bonding” process, where we bury a copper ground ring around the pool to keep the area shock-free. By staying strictly in line with local codes and using high-quality GFCI protection, we make sure your electrical system is invisible, reliable, and, most importantly, safe for every person and pet that jumps in.
Recessed Lighting Installation
At Cob Services LLC, we know that the right lighting does more than just brighten a room—it completely changes how your home feels. While LED recessed lighting has become the gold standard for modern homes, the real magic is in the layout; the wrong placement can leave you with awkward shadows or a space that feels too clinical. Drawing on decades of hands-on experience, we sit down with you to design a custom plan that finds the perfect balance of quantity and style for your kitchen, basement, or living area. We’re here to take the guesswork out of the process, helping you select the ideal fixtures and placements so your next project results in a warm, inviting atmosphere you’ll love coming home to.
Why are my lights flickering?
There’s nothing more annoying—or a bit unnerving—than sitting down to relax only to have your lights start flickering like a scene from a horror movie. At Cob Services LLC, we know that blinking lights are usually your home’s way of trying to tell you something is wrong. Sometimes it’s a simple fix, like an old dimmer switch that isn’t playing nice with your new LED bulbs, but other times it can be a “red flag” for loose wiring or a worn-out electrical panel. Because these glitches can occasionally lead to serious overheating or sparking behind your walls, we take the guesswork out of the situation. We’ll get to the bottom of the flicker, tighten up any loose ends, and make sure your home’s electrical heart is steady and safe.
What is a Federal Pacific electrical panel and are they dangerous?
If you’ve discovered a Federal Pacific logo on your electrical panel, you’re likely feeling a bit of “homeowner anxiety”—and for good reason. At Cob Services LLC, we don’t believe in using scare tactics, but we do believe in keeping our neighbors safe. These specific panels were a household staple for decades, but time and testing have shown a serious flaw: their breakers often fail to “trip” or shut off when the circuit gets overloaded. Instead of cutting the power to protect your home, the electricity keeps flowing, which can lead to overheating, melted wires, or even a fire behind your walls. We treat these panels as a top priority because “invisible” electrical risks are the ones that keep us up at night. If you have one, we’re here to help you swap it out for a modern, reliable system that actually does its job when you need it most.
What is a GFI outlet, and where are they required?
We like to think of a GFCI (or Ground Fault Circuit Interrupter) as a tiny, lightning-fast “lifeguard” built right into your wall. At Cob Services LLC, we install these anywhere water and electricity might cross paths—like your kitchen, bathroom, garage, or outdoor patio. Their only job is to watch your power like a hawk; if they sense even a tiny “leak” of electricity that could cause a shock, they snap the power off in a fraction of a second—much faster than a standard breaker ever could. You’ll recognize them by those “Test” and “Reset” buttons on the face. If you have older outlets near your sinks or outside that don’t have these buttons, it’s a small upgrade that gives you a huge amount of peace of mind.
Why are my lights flickering?
There’s nothing quite as unsettling as sitting down to relax only to have your lights start flickering like a scene from a horror movie. At Cob Services LLC, we know those blinking lights are usually your home’s way of trying to tell you something is wrong. Sometimes it’s a simple fix, like an old dimmer switch that isn’t playing nice with your new LED bulbs, but other times it can be a “red flag” for loose wiring or a worn-out electrical panel. Because these glitches can occasionally lead to serious overheating or sparking—known as arcing—behind your walls or at your exterior meter, we take the guesswork out of the situation. We’ll get to the bottom of the flicker, tighten up any loose ends, and make sure your home’s electrical heart is steady and safe.
Why did my breaker trip?
It is incredibly frustrating when you’re right in the middle of something and—click—the power cuts out and leaves you in the dark. At Cob Services LLC, we find that a tripping breaker is usually your home’s way of protecting itself from two main culprits: an overload or a short. Think of an overload like a crowded highway; when you plug in too many high-power gadgets at once, the “traffic” gets too heavy and the breaker trips to keep the wires from overheating. Usually, you can just unplug the toaster or hair dryer and flip the switch back. A short circuit, however, is a bit more serious—it happens when a live wire accidentally touches a neutral or ground wire, causing a sudden, dangerous surge. In those cases, the breaker will often snap back instantly if you try to reset it. If your breaker refuses to stay “on,” it’s your home’s safety system waving a red flag, and that’s exactly when our team steps in to find the trouble spot and get your life back up and running safely.
What is an electrical emergency?
At Cob Services LLC, we consider an electrical emergency to be any moment where your home’s wiring goes from “acting up” to feeling genuinely dangerous. Whether it’s a sudden spark, a scary burning smell, or a shock when you touch an appliance, these are red flags that can’t wait. If you’re seeing smoke or hearing loud popping, don’t second-guess your gut—shut off the power and call for help. Whether it’s us or the fire department, our priority is getting on-site fast to stop a flickering problem from becoming a fire, so you and your family can breathe easy again.
Why is my light switch or dimmer hot?
It’s a bit startling when you reach to turn off a light and the switch feels warm—or worse, hot to the touch. At Cob Services LLC, we want you to know that while some dimmers naturally get a little warm as they work to dim your lights, they should never feel like they’re burning you. Usually, a hot switch is a warning sign that it’s being overloaded with more wattage than it can handle, or there’s a loose wire inside the wall causing dangerous heat to build up. If a dimmer gets too hot, it’ll eventually just give up and fail, but a standard switch getting hot is a red flag that needs a look right away. We can help you track down the cause, whether it’s a simple compatibility issue or a connection that needs tightening, to keep your walls cool and your home safe.
