Whole House Rewiring in Naperville, IL

If your Naperville home still runs on the wiring it was built with, you’ve probably noticed it. The breaker trips when the microwave and the toaster are on together. An outlet feels warm. The lights dip for a second every time the AC starts up. That’s the house telling you the electrical is getting old. I’m Alexandr Godonoaga, I own Cob Services LLC (License #26-00032356), and my crew has rewired a lot of homes around Naperville and the rest of the western suburbs. We do whole house rewiring the right way: up to Illinois code, on a schedule we actually keep, and with as little damage to your walls as the job allows.

Old wiring is more than an annoyance. Knob-and-tube and the early aluminum wiring were never meant to carry what a modern house pulls, and a lot of Illinois insurers have stopped covering homes that still have them. A full rewire takes that problem off the table. Mostly, though, it just makes the house safer, and that’s the part I’d want fixed if it were my family in there.

What Whole House Rewiring Actually Involves

We replace the old wiring running through your walls, ceilings, and floors with new copper that meets current Illinois electrical code. The old circuits come out, new ones go in, and we update the outlets and switches along the way. Everything ties back to a panel that can handle the load. If the panel itself is on its last legs, we’ll bring that up before we start, because new wiring feeding an old panel doesn’t make much sense.

Most Naperville rewires run a few days to a week. It depends on how big the house is and how hard the walls are to get into. We go room by room so you’re not living in a construction zone the whole time. When the work’s finished it gets inspected and signed off, so you’ve got paperwork proving the house is up to code.

Signs Your Naperville Home Needs Rewiring

You don’t have to wait for something to go wrong before you call a wiring installer near you. A few things that usually mean it’s time:

• The house was built before 1985 and has never been rewired
• It still has knob-and-tube or aluminum wiring
• Breakers trip a lot, or you’re still running on fuses
• Outlets or switch plates feel warm, or you’ve spotted scorch marks
• Lights flicker or dim when an appliance kicks on
• You’ve only got two-prong outlets with no grounding
• You’re renovating, adding a room, or finishing the basement
• You’re buying or selling an older home and the inspection flagged the wiring

If a couple of those sound like your house, have us take a look. An inspection costs very little, and it’s a lot cheaper than finding out the hard way.

Why old house rewiring in Naperville is worth it

Rewiring a house costs real money. I won’t pretend otherwise. But it earns that money back in ways most home projects don’t.

• New wiring cuts the risk of an electrical fire way down. For most of my customers that’s the whole reason they call.
• The house meets current code, which keeps your insurer happy and removes a headache at resale.
• Updated electrical is one of those upgrades buyers and inspectors actually look for, so it holds its value.
• You get room to grow. New wiring means you can add a circuit for an EV charger, a hot tub, or a finished basement without overloading anything.
• The lights stop dimming every time the dryer runs, because the big appliances get their own dedicated circuits.
• Modern wiring and a modern panel just handle today’s electronics better than 40-year-old aluminum ever did.

Whole house rewiring FAQs

How much does whole house rewiring cost in Naperville, IL?

It comes down to the size of the home, how easy the walls are to reach, and whether the panel needs replacing too. Every house is a little different, so we give free in-person estimates instead of throwing out a number over the phone. Call (630) 427-5923 and we’ll come look.

How long does it take to rewire a house?

Most rewires take a few days up to about a week. We work room by room so your home stays livable while we’re there.

Do I need to move out during a rewire?

Almost never. Because we work in sections, most families stay put the whole time. If any part of the job needs the power off for a while, we’ll tell you ahead of time.

Is knob-and-tube wiring dangerous?

It can be. It wasn’t built for modern electrical loads, it has no ground, and a lot of insurers won’t cover a house that still has it. If yours does, rewiring is the safe fix.

Will rewiring add value to my home?

Yes. Updated, code-compliant wiring is something buyers and home inspectors look for, and it clears up a common sticking point when older homes change hands.

Are you licensed and insured?

Yes. Cob Services LLC carries Illinois electrical license #26-00032356. We pull permits and have the work inspected, so you’re left with documented wiring that meets code.
