Many Harleigh, PA properties constructed between 1965 and 1973 still rely on original aluminum branch circuit wiring. Our licensed team evaluates your electrical system, flags potential hazards, and delivers lasting, code-approved fixes to keep your household protected.
In the late 1960s and into the early 1970s, builders across the country — including many Harleigh, PA neighborhoods — turned to aluminum wiring in place of copper for interior circuits. Copper prices were climbing at the time, making aluminum a cheaper substitute, and it went into thousands of homes before the risks tied to its long-term performance were fully recognized.
The trouble stems from how aluminum behaves compared to copper under electrical load. As current passes through the wire, it heats and cools, and aluminum expands and contracts more than copper does. Repeated over many years, this movement gradually loosens the wire at its termination points — inside outlets, switches, junction boxes, and breaker panels. A loose connection is a common precursor to electrical fires because it builds resistance, and resistance produces heat. Federal safety researchers have found that older homes wired with aluminum face a markedly higher likelihood of a fire-related failure at these connection points compared to homes wired in copper.
There's also the matter of oxidation: exposed aluminum reacts with air and forms a coating that adds resistance right where connections are made. Most electrical devices on the market are built with copper in mind, so pairing them with aluminum wiring — without the correct hardware and anti-oxidant paste — only compounds the danger. If your Harleigh, PA home dates back to this construction window, or its wiring has simply never been checked by a professional, booking an evaluation with Brightline Electrical is a safety step worth prioritizing now.
Brightline Electrical relies on two industry-accepted methods for correcting aluminum wiring issues in Harleigh, PA homes. Choosing the right one depends on how widespread the wiring is, the current state of your connections, your budget, and how long you intend to stay in the home. Our electricians will walk through your options on-site before any work is scheduled.
The more comprehensive solution is a full copper rewire, which removes the aluminum wiring altogether and installs an entirely new copper circuit system. This route offers the strongest long-term protection and tends to make sense for homes where the aluminum has already begun to deteriorate, or for owners planning to stay put for years to come. It takes more time and costs more upfront but leaves you with a fully modern, compliant system.
The second option is pigtailing — splicing short copper leads onto the ends of the existing aluminum wires at every connection point, using UL-listed twist connectors built specifically for joining aluminum to copper (commonly known as COPALUM or AlumiConn connectors). The aluminum stays in place but is safely capped off at each termination with the proper connector and anti-oxidant compound. It's a much less invasive process than a full rewire and is recognized by federal safety regulators when carried out correctly by a qualified electrician. Our Harleigh, PA crew has completed this procedure in countless homes, always taking care to document each connection thoroughly for your records.
Don't let aluminum wiring concerns sit unaddressed. Our licensed electricians are ready to inspect your Harleigh, PA property and lay out a clear plan toward a safer electrical system. Reach out today to get started.
