If you own a home built between 1965 and 1973, you might be sitting on a dormant fire hazard. During the Vietnam War era, copper prices skyrocketed, leading builders to use single-strand aluminum wiring in millions of homes. While aluminum conducts electricity, it behaves differently than copper, leading to a risk that increases with every passing year. Sperry Electric LLC is dedicated to identifying and neutralizing this risk so you can sleep soundly.
The science behind the danger is simple but frightening. Aluminum is a softer metal than copper and expands much more when heated. Every time you turn on a hair dryer or vacuum, the wires in your wall heat up slightly and expand. When you turn it off, they cool and contract. Over decades, this constant movement loosens the connection between the wire and the outlet screw. A loose connection creates electrical arcs—tiny sparks that generate intense heat (up to 5000°F), which can ignite the insulation and surrounding wood studs.
The first step is identification. You can check the markings on the cable jacket in your basement or attic; look for "AL" or "aluminum." If you confirm its presence, you need to act. Do not try to tighten these screws yourself. Aluminum builds up an oxide layer that is non-conductive, and messing with it without the right tools can actually make the connection worse. You need professional Electrical Repairs in New Jersey to handle this delicate material.
The gold standard for fixing this issue without a complete house rewire is a process called "pigtailing" using COPALUM or AlumiConn connectors.
This involves attaching a short piece of copper wire to the end of the aluminum wire using a specialized connector that prevents oxidation and maintains consistent pressure. The copper end is then connected to your switches and outlets. This bridges the gap safely, allowing you to keep your existing wiring while eliminating the connection hazard.
This repair is not a DIY project. Standard wire nuts will melt if used on aluminum-to-copper connections. You must use devices specifically listed for this purpose, installed by a pro who knows the correct torque specifications. This remediation is often required by insurance companies to maintain coverage on older homes.
Conclusion Aluminum wiring is a serious issue, but it has a proven solution. You do not need to tear down your walls to make your home safe. By investing in professional remediation, you eliminate the fire risk and restore the integrity of your electrical system.
