Things You Should Know When Upgrading Electrical Wiring For A Historic Home

Posted on

If you own a historic home and have not upgraded or replaced the electrical wiring, you and your family may not be entirely safe. Older wiring can hide dangerous issues. However, because you have a historic home, you cannot simply install a new system without taking some things into consideration first. Below is some helpful information about upgrading your electrical system to keep your family safe.

When You Should Upgrade

One of the most important reasons why you need to upgrade your electrical system is for your safety. Old wiring deteriorates over time. This can result in the wiring shorting out and it may cause sparks. This will result in a fire.

Your electricity demands may also have increased, and too great of a demand can cause wires to short circuit. Because you have an older home, you may have a 60-amp service. When the home was built, things like audio systems, microwaves and computers were not taken into consideration in determining how much power a home needs. Sixty amps is not enough power to run multiple appliances all at once, such as a hot water heater, dryer, and electric stove. You would need to upgrade your home to at least 200 amps.

Some warning signs that you need to upgrade your wiring include:

  • Lights dimming
  • Lights flickering
  • Breakers trip repeatedly
  • Burning smell from an appliance or room
  • Outlets spark
  • Outlets discolored

Expensive and Messy

It can cost up to $8,000 to rewire a moderate-sized house that has easy access. However, if you have a larger house and the wiring is difficult to access, it could cost up to $30,000 to upgrade your wiring.

You should also expect the job to be very messy. The electrician will have to tear out walls to gain access to the current wiring. You may need top to bottom rewiring. For example, you may need to add power for a new addition, or you may have a new appliance and need to add more circuits.

If you are planning to remodel your home, such as upgrading a kitchen or adding on a new addition, this is the best time to upgrade your wiring because the building contractors will have to tear out walls anyway.

Contact an electrician to come to your home to go over all this with you. They can also make sure your wiring is up to codes. Visit a site like for more information.
