When to Rewire an Older Home: A Comprehensive Guide

Older homes come with charm and character, but they also often have outdated electrical systems that can pose serious risks. Rewiring an older home can increase safety, energy efficiency, and home value. Here’s how to know when it’s time to call a professional to rewire your home.


  • Frequent Blown Fuses or Tripped Breakers: Outdated wiring can’t handle the demands of modern appliances.
  • Flickering or Dimming Lights: This can indicate loose wiring or overloaded circuits.
  • Burning Smells or Discolored Outlets: These are signs of potential fire hazards from faulty wiring.
  • Old Knob-and-Tube or Aluminum Wiring: These older wiring methods are prone to failure and are no longer up to code.

  • Updated Electrical Panels: Consider installing a 200-amp service panel for modern power needs.
  • Smart Surge Protectors: Protect devices with the Belkin Surge Protector Power Strip to prevent damage from surges.
  • GFCI Outlets: Install GFCI outlets in kitchens and bathrooms for safety against electrical shock.

While small tasks, like installing a light fixture, can be DIY-friendly, rewiring a home requires professional expertise. Licensed electricians ensure the work meets code and avoids safety risks.

Pro Tip: If you’re renovating, it’s the perfect time to rewire, since walls are already open. This saves both time and money.


Rewiring an older home can be a significant investment, but it’s essential for ensuring the safety and functionality of your electrical system. Look for signs like frequent electrical issues and outdated wiring types to know when it’s time to upgrade. A licensed electrician can guide you through the process and help bring your home up to modern standards.
