Common Electrical Issues In Older Homes

July 10, 2020 | Blog

It makes a lot of sense that you’re likely to experience more electrical problems in an older home than a new build. Electrical wiring becomes a mess of materials mixed together by different electricians over the years, bound to create issues as time passes.

So what should you look out for? Here are some of the most common electrical issues in older homes.


Lots of old homes suffer from outdated wiring, like cloth or aluminum covered wiring. Cloth covered wiring tends to be flakey and brittle, causing the under-wiring to become exposed.

On the other hand, aluminum expands and contracts in response to heat. It will eventually cause the wire to overheat due to corrosion and oxidation. Both types of wiring are extremely dangerous and could potentially lead to house fires.

Not only can old and outdated wiring cause a fire, but they can also cause sparks and further damage to your outlets.

Flickering Lights

Just like old wires, old electrical connections can become loose, flimsy and weak. It’s common for older houses to have different types of wiring for their lighting, which could cause corrosion.

Corrosion is what leads to flickering lights and tripped switches. As the wiring continues to become weaker and break down, the wire will heat up and could start a fire. In a less extreme case, your lights could flicker due to a loose bulb.

Either way, call an electrician to solve the problem for you and your home’s safety.

Bad Outlets

If your outlets stop working, it could be because of tripped breakers. With older houses, however, even resetting your breaker may not do the trick. Your outlets could be burned out or loose, usually marked by scorch or burn marks.

These are signs to immediately call an electrician. For electrical safety, do not attempt to plug in anything into your dead outlets. This could lead to electrocution or a house fire.

Tripped Breakers

Circuit breakers frequently tripping means that your boards are overloaded. When overloading occurs, it’s time to call an electrician and to have your circuit inspected.

Older homes are great – but they can come with a slew of problems. That’s why we’re here to help. Call Arnold Electrical Services to speak with a professional Chicago electrician today.

What Our Clients Say

Fantastic Service

I have used Arnold Electric a few times for my business. I wasn’t sure what my options were for lighting in my office. Jack was so nice to bring some samples for me to try before installing! They are wonderful!

Dr. Lauren Shultz

Reliable and Professional

The team over at Arnold Electric has been great to work with. We recently purchased a home and have had Pedro out to do a review of the electrical system, make some minor repairs and present some options to improve the out dated and DIY wiring in our home. The team has done a great job of communicating expectations and explaining everything for us.

Excellent Work

Very easy to work with, excellent work on jobs big (new underground line to a detached garage) and small (changing the interior fixture.

Lauren Harms

Punctual, Courteous and Clean

This company is absolutely the most professional and conscientious electrical contractor I’ve ever had the pleasure of hiring. I’ve used them several times from things like replacing my electrical panel, to wiring issues, to installing a ceiling fan. I will also use them for anything else electrical going forward. They’re always punctual, courteous and clean. I’m very particular, and hard to please. I’m not afraid to call and complain about less than perfect service from anyone I hire. Arnold Electrical Service, thank you for all the jobs well done!

Douglas Sheehan

Reasonable Price & Professional

Joe came to my house to fix a dumb thing I did. (DON’T DO YOUR OWN ELECTRICAL WORK!) He was friendly, fast and very helpful, answering all my questions in a polite and tolerant manner.
The charges were very reasonable for the professional quality service I received. They will be coming back to do some new wiring and circuits soon. Highly Recommend!
