Back in the 1960s and early 1970s, home builders often used aluminum wiring for new homes instead of the increasingly expensive copper alternative. Today, many or most homes built during that period still have the original aluminum wiring.

The longer the weak wiring type stays in use, the worse its condition becomes. Read on to understand why aluminum wiring is a serious fire hazard and should be promptly replaced.
