Risks of Aged Residential Wiring

Did you know homes built around 50 years ago often have aluminum wiring over copper, and homes built 100 to 150 years ago often feature “knob and tube” wiring?

Why does aged wiring matterfor a homeowner?

Aluminum wiring is inferior over copper. If not properly maintained, it becomes defective faster due to certainqualities inherent in the metal. It builds up more heat than copper and causes the wires to stretch and move. This may result in the wires moving over or against other surfaces. It is not only damaging to the wiring, but the overheating can cause arcs and fire hazards.

“Knob and tube” wiring is generally fine unless splicing and alterations were done over the years (to make it compatible with modern appliances) were done incorrectly, thus creating a fire hazard.

Signs of problematic residential wiring include:

  • Damaged appliances
  • Burned insulation
  • Blown circuits
  • Burning around outlets or warm to the touch cover plates
  • Flickering lights

Moreover, due to the high risks, some insurance companies will not write homes with aluminum wiring.

How does one know what kind of wiring their home has?

Look for printed or embossed markings on the outer jacket of the electric cables, which are visible in unfinished basements, attics or garages. Keep in mind that plated copper wire (tinned copper wire) is relatively common in older homes, and can look similar to aluminum wire.
