Aluminum Wiring Replacement in NJ — AlumiConn & COPALUM Remediation

Aluminum branch-circuit wiring — common in NJ homes built between 1965 and 1973 — expands and contracts more than copper as it heats and cools. Over time that loosens connections at outlets, switches, and splices, and aluminum also oxidizes, creating high-resistance spots that overheat. The U.S. Consumer Product Safety Commission (CPSC) found homes with this wiring are far more likely to reach fire-hazard conditions at connections than homes wired with copper. It is not the large aluminum service cable feeding your panel (that is normal) — it is the smaller aluminum wiring running to individual devices that is the concern.

Both are CPSC-recognized permanent repairs for aluminum branch wiring. COPALUM is a special crimp that bonds a short copper 'pigtail' to the aluminum wire; it requires a certified installer and special tooling and is increasingly hard to source. AlumiConn is a three-port lug connector that pigtails copper onto the aluminum at each device with a torqued, listed connection — it is widely available, code-recognized, and what most NJ electricians (including us) use today. For some homes, full replacement of the aluminum branch wiring with copper is the better long-term answer. We assess your home and recommend the right approach.

AlumiConn pigtailing typically runs $35–$75 per device connection, so a whole-home remediation generally lands around $1,500–$5,000 depending on how many outlets, switches, and fixtures you have. A full replacement of the aluminum branch wiring with new copper is a rewire-scale project — usually $8,000–$20,000 for a single-family home — and makes sense when the wiring is damaged or you're renovating anyway.

Many NJ insurers treat aluminum branch wiring the same way they treat knob-and-tube: they may decline new coverage, refuse to renew, or require remediation as a condition of the policy. The good news is that a documented AlumiConn or COPALUM remediation by a licensed electrician usually satisfies the carrier. We provide the permit record and municipal inspection sign-off so you can show your insurer the work was done correctly.

Yes — remediating or replacing aluminum branch wiring in New Jersey is permitted electrical work that requires a municipal electrical permit and a final inspection. Malfettone Electric pulls the permit, performs the AlumiConn pigtailing or full replacement, and schedules the inspector. You receive the permit record and completion documentation for your files and your insurer.
