Aluminum Wiring Remediation
Quick answer
Homes wired 1965–1973 often have aluminum branch wiring, a documented fire risk at connections. CPSC-recognized remediation (COPALUM or AlumiConn) costs $1,500–$8,000, far less than a full rewire.Typical installed cost: $1,500–$8,000
Aluminum branch wiring isn't automatically dangerous, its connections are. Aluminum expands, contracts, and cold-flows at terminations, loosening over decades until they overheat. Remediation repairs every connection with CPSC-recognized methods, keeping the wiring and removing the risk.
About Aluminum Wiring Remediation
Between 1965 and 1973, copper prices pushed builders to aluminum branch wiring in roughly two million American homes. The metal itself carries current fine; the problem is at every screw and splice, where aluminum's expansion, oxidation, and cold-flow gradually loosen connections until they run hot. The CPSC found these homes dramatically more likely to have fire-hazard conditions at outlets.
Remediation fixes the connections, not the wire: COPALUM crimping (the gold standard, a factory-tooled copper pigtail at every termination) or AlumiConn lugs (the accessible alternative). Every outlet, switch, splice, and fixture connection in the home gets treated, documented, and photographed for your insurer.
Remediation vs full rewire
- COPALUM/AlumiConn remediation: $1,500–$8,000, keeps existing wiring
- Full rewire: $8,000–$20,000+, for damaged or heavily modified systems
- Both restore insurability; remediation is the CPSC-recognized value path
- Purple twist-on 'AL/CU' wire nuts alone are NOT a recognized fix

Usually not. CPSC-recognized remediation, COPALUM crimps or AlumiConn connectors at every termination, addresses the hazard at a fraction of rewiring cost. Full replacement is for damaged or badly modified installations.
Homes built or expanded 1965–1973 are the prime window. Cable jackets marked 'AL' or 'ALUMINUM' at the panel are the giveaway, we confirm during a free assessment.
Many insurers require remediation or surcharge until it's done. Documented COPALUM/AlumiConn remediation typically restores standard terms.
Typically 1–3 days depending on device count. Power is off per-circuit as we work, not whole-home.
Usually solvable: a documented remediation quote (or completed work) satisfies most lenders and insurers, and it's a common negotiation item. We turn assessments around fast for transactions.
