Electrical Repair and Replacement Costs: What Homeowners Should Expect

Buzzing behind your walls at any given moment is the stuff that makes it possible to both doomscroll on your smartphone and binge-watch on your television — or even do both at the same time, if you so wish.

Your home’s electrical system is the gateway to all modern comforts, from your fridge to your Wi-Fi router to your robot vacuum, and maybe even your furnace and water heater, if you’ve given up on gas. So if something were to go, well, haywire, it’s understandable that you’d find yourself in a bit of a pickle.

Electrical issues are no joke. Electrical fires are among the most common types of house fires, with damaged wiring, faulty outlets and overloaded circuits often the culprits. Contact with live wires can cause electric shock or burns.

Needless to say: If you suspect something is wrong with your electrical system or wiring, you shouldn’t wait to schedule a repair with a licensed and qualified electrician. If you do see signs of electrical issues — like warm outlets, sparks or a burning plastic smell — go ahead and turn off the power at the breaker.

But just scheduling a repair is easier said than done, of course, and repairs can be pricey. Average electrical repair and replacement costs have increased up to 3% over the past four years — according to aggregated HomeServe data as reported by our nationwide network of contractors — while as many as 41% of homeowners have less than $500 saved for a home repair emergency.

A look at national average repair prices might help ease the sticker shock by giving you an idea of what that bill from the electrician might look like.

Faulty 200-Amp Panel Replacement: $1,354

A “200-amp panel” is another way of referring to your breaker box — you know, the thing that holds the switches you have to flip back on when your hairdryer gets out of control.

Breaker boxes can show their damage in all sorts of ways. You might notice that your panel is hot or smells like melted plastic. This is a dead giveaway that something is wrong. More subtle presentations include rust or loose switches. You may also find that you have to flip tripped breakers more often as your breaker box wears out.

Replacing a faulty 200-amp panel carries a national average cost of $1,354. This price is 5% higher than in 2022 and 8% higher than in 2020.

Faulty GFCI Outlet Replacement: $274

Ground faults occur when electricity goes rogue and takes an alternate path to the “ground” via something like water or a person’s body, which can result in electrocution. Ground-fault circuit interrupter outlets automatically shut off when they detect ground faults. They’re the kind with the “test” and “reset” buttons, and they’re most commonly found in parts of your home where the walls might get wet, like the kitchen or bathroom. 

Signs of a bad GFCI outlet include:

• No power to the outlet

• Outlet won’t reset, or the “reset” button is stuck

• Plugs fall out of the outlet

• Outlet trips often

To replace a GFCI outlet, you can expect to pay somewhere around the national average cost of $274. Prices have increased 10% since 2022, and 19% since 2020.

Interior Wiring Repair or Replacement: $375

There are a number of signs your electrical wiring might need to be repaired or replaced, including:

• Your circuit breaker trips all the time. Your electrical system might not be able to handle everything you throw at it — especially not all at once. But if you notice your circuit breaker tripping with fewer appliances plugged in at one time, you might want to have your wiring checked out.

• Your outlets have scorch marks. Dark black burn marks on an outlet are pretty scary-looking. And they’re a telltale sign that something is wrong with either the appliance you had plugged in or the wiring behind the wall.

• Your walls feel warm. If the wall near an electrical outlet feels warm, don’t panic right away. Simply having something plugged in for a long period of time (like a laptop charger) can make the wall around an outlet feel warm. But if you haven’t recently plugged anything in and the wall still feels hot, you could have loose or damaged wiring behind that wall that needs quick attention from an electrician.

• Your wiring is just old. If your home is more than 25 years old and has never been rewired, the wiring may be worn out from regular use.

Whatever the cause, repairing or replacing a section of wiring is likely going to cost about $375. That’s 8% more than in 2022 and 19% more than in 2020. Keep in mind that rewiring an entire house will cost a lot more.

Diagnostic Fee

Something to keep in mind is that a lot of electricians (like many other types of service professionals) charge a “callout” fee. Often referred to as a “diagnostic” fee, this is basically just how much it’s going to cost to get an electrician to drive to your home, crack open your wall and look at your wires. Even if they don’t find anything wrong, they will likely bill for this time.

This pricing does not reflect emergency repairs, which can often cost more due to services needed on short notice or after hours.)
