If your home was built or wired between the mid-$1960s$ and early $1970s$, there's a significant chance it contains aluminum electrical wiring. While initially seen as a cost-effective alternative to copper, decades of real-world application, backed by extensive research from organizations like the U.S. Consumer Product Safety Commission (CPSC), have revealed inherent and serious safety concerns associated with aluminum branch circuit wiring.
The use of aluminum wire for residential branch circuits, particularly from $1965$ to $1973$, stemmed from a period of high copper prices. However, the properties of aluminum, when compared to copper, make it inherently less suitable for these applications without specific, costly connectors and installation methods that were not commonly used at the time.
If you see these signs in a home built in the 60s or 70s, your electrical system might be a ticking time bomb.
Aluminum expands and contracts more than copper when heated. Over time, this causes connections to loosen. A loose connection increases resistance ($P = I^2 R$), generating dangerous heat.
Aluminum oxidizes when exposed to air, forming an insulative layer. This creates poor electrical contact and localized heating, especially at copper-aluminum junctions.
Under pressure, aluminum wire can deform or "creep" away from screws. This reduces the contact area, further increasing resistance and fire risk.
Early installations used devices designed for copper. These were not rated for aluminum and could not maintain secure, lasting connections.
The CPSC estimates that homes wired with aluminum have a $55$ times higher risk of fire than homes wired with copper.

We replace aluminum-rated devices with new copper-rated devices and install copper pigtails using CPSC-accepted connectors to eliminate problematic aluminum-to-device connections.
The ultimate peace of mind. We remove all existing aluminum branch circuit wiring and install modern copper cables, upgrading your panel and devices to current National Electrical Code (NEC) standards.
Our team in Washington Grove, MD is fully licensed, insured, and possesses specialized training in aluminum wiring remediation.
We employ meticulous diagnostic procedures and use only CPSC-approved materials to meet or exceed local codes.
We provide clear, upfront quotes with no hidden fees, ensuring you understand the investment before work begins.
A: The most reliable way is a professional inspection. If built between 1965-1973, the likelihood is high. Look for silver-colored wires or "AL" stamps on wire insulation.
A: Yes, but it may impact the sale. Buyers may request remediation as a condition of sale, and securing insurance can be difficult for the new owner.
A: A full rewire can take several days to weeks, while targeted pigtailing can often be completed much faster. We provide detailed timelines after inspection.
