You may notice your lights flickering, or feel a warmth coming from your light switch cover plates. ![]() One of the first signs your home may have aluminum wiring is that its electrical features fail to perform as well as they should. ![]() Wiring that has been in use for so long may now be starting to degrade, even if it has previously worked without issues, so getting a head start on replacement can save your home from electrical problems and damage. If you suspect aluminum wiring in your home’s construction, you may want to begin thinking about whether to put in additional safety features or replace it with copper wiring. If you live in a home built in the 1960s or 1970s, it may have aluminum wiring. Even though copper prices have continued to increase in recent decades, construction companies and contractors have relied more on copper wiring because of its superior performance and safety benefits. Aluminum is generally less expensive than copper, so using copper rather than aluminum wiring allowed construction companies to lower their expenses and pass those cost savings on to homebuyers. When Was Aluminum Wiring Typical in Homes?Īluminum wiring is characteristic of homes built from the mid-1960s to the mid-1970s. In the 1960s, copper prices rose sharply, starting the decade at about 29 cents per pound and skyrocketing to about 76 cents per pound by 1966. In others, faulty aluminum wiring can cause flickering lights, interfere with electrical appliances’ performance or spark fires. In some houses, the aluminum wiring functions perfectly for many years, especially if the home contains specialized connectors that help prevent the issues we’ve discussed.
