Aluminum branch circuit wiring was used in approximately 2 million homes built between 1965 and 1973 as a cheaper alternative to copper during a period of high copper prices. Unfortunately, aluminum wiring has proven to be a significant fire hazard -- the Consumer Product Safety Commission (CPSC) reports that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions than homes with copper wiring. The problem stems from aluminum's tendency to oxidize, expand and contract at a different rate than copper and steel connections, and develop loose connections that overheat and arc over time. AJ Long Electric provides professional aluminum wiring remediation throughout the DMV — Northern Virginia, Washington DC, and Maryland. We offer two proven remediation approaches: complete rewiring with copper (the gold standard) or COPALUM crimp connections at every junction point, which is the only repair method recommended by the CPSC. Our licensed electricians inspect every outlet, switch, junction box, and connection point in your home, identifying all aluminum wiring locations and assessing their condition. We then perform the selected remediation method throughout the home, ensuring every connection is safe, secure, and code-compliant. This is one of the most important safety upgrades you can make to a home with aluminum wiring.
