Aluminum Wiring Remediation
Older aluminum branch-circuit wiring needs an on-site review of the accessible conductors and connections. We identify the wiring involved, explain the repair paths, and provide a scope for the home.
Confirm the wiring
Accessible cable markings, devices, junction boxes, and panel information establish whether older aluminum branch wiring is present and where it terminates.
Compare repair paths
The CPSC discusses COPALUM and AlumiConn repairs for affected aluminum branch-circuit connections. Copper replacement can also be appropriate when the wiring or renovation scope calls for it.
Plan the wider work
A remediation review may also reveal grounding, panel, or rewire decisions. Those are separate decisions, described separately in the proposal.

This service concerns older aluminum branch-circuit wiring, the smaller conductors that serve receptacles, switches, and lighting circuits. The practical issue is the condition of the connections, where conductor and terminal compatibility and workmanship matter.
That is different from assuming every aluminum conductor in a home is defective. Larger feeder or service conductors have a different use and must be evaluated as part of the actual equipment and connection arrangement. A label, an accessible inspection, and the home’s plans are more useful than a conclusion based only on its construction date.
Warm or discolored wall plates, a burning-plastic odor, flickering lights without an obvious appliance cause, buzzing, or a breaker that repeatedly trips can indicate an electrical problem. Those signs do not diagnose aluminum wiring by themselves, but they are a reason to stop treating the circuit as routine.
Do not remove covers, tighten terminals, or experiment with connectors to investigate. If there is smoke, fire, sparking, or immediate danger, leave the area and call 911. Otherwise, stop using the affected circuit where it is safe to do so and arrange an electrical assessment.
CPSC Publication 516 identifies the COPALUM repair and says an AlumiConn connector may be considered when COPALUM is unavailable. Both approaches concern a properly installed copper pigtail at affected connections. Availability, product instructions, box conditions, conductor condition, and the confirmed scope all matter.
Replacing a switch or receptacle with equipment marked for aluminum use is not the same as a whole-connection remediation program. It may address that device terminal, while inaccessible splices and fixture connections remain separate questions. Copper replacement removes affected branch wiring, but its access and finish-restoration scope can be broader.
The visit starts with the panel and the accessible parts of the home: devices, junction boxes, attic or crawl-space wiring where available, and records from a prior inspection or renovation. This establishes a working inventory and shows where additional access may be necessary.
A useful proposal states the repair method, the locations included, access assumptions, and any related work that is optional or outside the initial scope. That clarity is especially valuable when a remodel, insurance question, sale, or other older wiring type is involved.
Some homes have more than one issue: aluminum branch wiring, ungrounded receptacles, cloth insulation, active knob-and-tube, or circuits altered over many years. A full rewire is not automatic, but it can be worth comparing when walls are already open or multiple systems need attention.
The right sequence depends on the home and planned work. We can separate connection remediation from grounding, panel, and whole-house wiring decisions so each choice has a defined purpose.
From our field photos
The close view records conductors at a panel termination bar. A branch-wiring assessment also needs to account for connections at receptacles, switches, fixtures, and accessible junctions. A connection inventory helps establish which devices and junctions belong in the repair scope.
The useful first answer is an inventory of accessible branch circuits and terminations. From there, the repair method and any larger modernization work can be discussed without treating every aluminum conductor as the same problem.
Document visible branch wiring, equipment, connections, and symptoms.
Compare appropriate remediation and related electrical work.
Perform the work according to the selected method and site conditions.
Cable markings and accessible conductors can help identify it, but an electrician should confirm the wiring and the connections involved. Do not open energized equipment or make repairs yourself.
No. This service addresses older aluminum branch-circuit wiring. Feeder and service conductors are a different application and should be assessed with their listed equipment and connections.
No. A device replacement concerns that terminal. Other splices and fixture connections require their own evaluation.
Stop using the affected circuit if it is safe to do so and seek prompt electrical help. For smoke, fire, sparking, or immediate danger, leave the area and call 911.
