5 Obvious Signs of Bad Electrical Wiring inside a House

Bad electrical wiring can result from an improper installation of the wiring or extreme weather that caused it to break or crack.

Now, how do you spot faulty electrical wiring? For a regular homeowner, it might be hard to know, especially when the wirings are all hidden behind the wall.

In this article, we will give you five obvious signs of bad electrical wiring that you should look out for.

Burnt Wires

One of the earliest signs of bad electrical wiring is burnt wires. If you spot blackened or charred wires, then it’s best to get this checked by a professional.

Cracked or Discoloured Wires

When you see the electrical wires in your home are cracked or discoloured, seek the help of a professional electrician. That’s because moisture can get into the wiring, which can cause it to rust or corrode.

Flickering Lights

The lights can flicker for many other reasons. However, if there are a lot of flickering lights in your home, it’s a clear sign that something is wrong with the electrical wiring.

Hot Electrical Outlets

This is when electrical sockets start getting hot after plugging a few appliances. It occurs because electricity transfers from the power source to the appliance, causing the outlet to feel hot.

If this happens to a lot of electrical outlets in your home, then it’s best that you get your wiring checked by a professional.

Short Circuit

Another early sign of bad electrical wiring is when your lights don’t turn on. This can be caused by a blown fuse or fuse switch, but an even more serious issue can be a short circuit in your house’s electrical wiring. A short circuit can damage the power source.

Can Faulty Wiring Increase Your Energy Bills?

Yes, faulty electrical wiring can cause higher energy bills.

However, it only happens if there is a short circuit in the electrical wiring. That’s because the electricity will just run through the faulty wiring, and this will cause the appliances to work harder to get the needed energy.

Can Bad Wiring Cause Fires?

Yes, faulty electrical wiring can cause fires but only when there’s a short circuit. When short circuits happen, the electrical power seeks another path to the ground, and that can be through the wiring in your home.

How to Prevent Bad Wiring

When you’re at the stage of deciding on a home, emember to ask the previous owner if there have been any electrical problems in the house.

If you’re buying a newly built house, make sure that the home builder followed the electrical codes as stipulated by the state laws. You can make an appointment with the home builder and ask some questions about the electrical wiring in the house.

If there is a wiring problem, then get it fixed before you move into the house. This will save you the time, hassle, and money that you’ll have to spend later on when bigger electrical problems occur.

What Is the Best Way to Fix Bad Wiring?

The best way to fix bad wiring is to hire an electrician to do the job.

Bad wiring is not something that you want to do yourself, especially when the electrical wiring is difficult to access. There are also cases when homeowners try to fix the bad wiring themselves, and the wiring gets more damaged. This can cause fires in the house.


To sum everything up, make sure that you regularly check for any signs of bad electrical wiring in your home. If you do find any signs of faulty electrical wiring, it’s best that you get this checked by a professional.
