By Cory Gilman, NJ licensed electrical contractor Aluminum wiring repair at Integrated Electrical Solutions uses the three permanent methods the U.S. Consumer Product Safety Commission recognizes: a full copper rewire, COPALUM crimp connectors, or AlumiConn connectors with copper pigtails. Integrated Electrical Solutions (NJ License #34EB01852700) works on 1965–1973 homes across Ocean, Monmouth, Middlesex, Mercer and Bergen Counties, and full copper rewires start around $8,000.
Aluminum branch wiring went into American homes mainly between 1965 and 1973, when copper prices were high. The wire inside the walls is usually still intact. The failures happen where the wire meets a screw terminal, a splice or a device.Aluminum expands and contracts more than copper as it heats and cools, so a screw connection slowly loosens. Bare aluminum also forms an oxide layer that conducts poorly, and aluminum touching a brass or copper terminal corrodes over time. Each of those raises resistance at the connection, and resistance turns into heat.
CPSC Publication 516 reports that homes built before 1972 and wired with aluminum are 55 times more likely to have one or more outlet connections reach "fire hazard conditions" than homes wired with copper. The Franklin Research Institute survey behind that number defined those conditions as cover-plate screws reaching 149°C (300°F), sparks from the receptacle, or charring around it. The finding describes connection failures, not 55 times more house fires.The federal concern goes back decades. A December 1974 National Bureau of Standards report (NBSIR 75-677), prepared for CPSC, examined the problems being reported with aluminum branch circuits. Manufacturers changed the alloy around 1972 and 1973. Hartford Insurance's aluminum wiring guidance describes wire produced since 1973 as "new technology" wire that is less brittle and creeps less under a screw than the earlier type.
Aluminum isn't banned. Ontario's Electrical Safety Authority notes that its code still permits aluminum wiring and that reported problems trace back to terminations, not the wire itself. That is why the repair focuses on every connection in the house.
Full copper rewires run $8,000–$14,000 for a 1,500–2,000 sq ft home, and connector remediation usually costs less.
Integrated Electrical Solutions confirms aluminum three ways before quoting anything. The cable jacket is usually printed AL or ALUMINUM. The conductors look silver rather than copper at the panel. Aluminum branch circuits also use heavier sizes, typically 12 AWG and 10 AWG where copper would be 14 AWG and 12 AWG.Home inspectors flag it too. The InterNACHI Standards of Practice require inspectors to report solid-conductor aluminum branch-circuit wiring as needing correction when it's visible. That report is often what starts the call during a sale. Ocean and Monmouth homes built between 1965 and 1973 in Jackson, Toms River, Brick, Howell, Freehold, Lakewood and Point Pleasant make up most of these calls. Same-era homes often also have a Federal Pacific Stab-Lok or Zinsco panel. That panel is a separate safety item with its own fix, covered on the panel upgrade page.
CPSC Publication 516 accepts three permanent repairs: replacing the aluminum branch wiring with copper, the COPALUM crimp method, and the AlumiConn connector as an acceptable alternative. Any of the three gets a New Jersey permit and a document an insurance underwriter will accept.
AlumiConn connectors, made by King Innovation, are approved by CPSC and UL and accepted by many insurance companies. Each connector has separate ports, so the aluminum and copper never share a screw. At every outlet, switch, fixture and splice, Integrated Electrical Solutions lands the aluminum in an AlumiConn with antioxidant compound, then runs a short copper pigtail to the device. A typical house has a couple of hundred of those connections. This is the usual repair when the aluminum conductors aren't scorched or brittle.
COPALUM, made by TE Connectivity, joins a copper pigtail to the aluminum with a powered crimp that cold-welds the two metals. CPSC has long described it as a permanent repair. The method needs a dedicated crimping tool and manufacturer training. Integrated Electrical Solutions doesn't keep that tool on the truck, so if an insurer specifically requires COPALUM, IES says so up front instead of pushing a full rewire.
A full rewire pulls or abandons the aluminum branch circuits and runs new copper. Integrated Electrical Solutions recommends it when insulation is heat-damaged, when walls are already open for a renovation, or when the owner wants aluminum out of the house entirely. A rewire also allows adding circuits for a kitchen, an EV charger or a heat pump at the same time.
AlumiConn remediation fits a house where the aluminum conductors are in good condition and the walls are closed. The work happens at each box, so there is little drywall damage and the job is usually shorter and cheaper than a rewire. A full copper rewire fits a house with scorched or brittle insulation, a planned renovation, or an owner who wants no aluminum at all. It costs more and takes 3 to 10 days, but it also allows new circuits and a modern layout.COPALUM fits when an insurer names it specifically. The cost usually falls between the other two because of the specialized tool and labor. One limitation applies to all three: the repair covers the branch circuits, not the panel. A Federal Pacific or Zinsco panel needs its own replacement regardless of which wiring repair is chosen.
Warm or discolored cover plates, flickering lights, a burning smell near a device, breakers that trip for no clear reason, and outlets that stop working intermittently all point to a failing connection. Scorched or melted insulation inside a box means the connection has already overheated. A house built between 1965 and 1973 with any of these signs should have its connections checked before more devices fail.

CO/ALR devices are rated for direct connection to aluminum. Leviton explains that CO/ALR terminal screws are plated with indium, and sells models such as the 2651-2W switch and the 12650-W receptacle. The National Electrical Code (NFPA 70) allows 15- and 20-amp receptacle terminals not marked CO/ALR only with copper or copper-clad aluminum. CPSC Publication 516 still calls CO/ALR devices, at best, an incomplete repair. The devices only cover outlets and switches, not splices, fixtures or junction boxes, and they failed in laboratory tests with the older wire. Purple twist-on connectors fall in the same category. Both are acceptable as an emergency fix for one failed connection, followed by a proper repair soon after.

"Cory and his great team at Integrated replaced my old unsafe electrical panel. The whole team did superb work and could not be happier. When they say they’ll be there at 8am that means 8am. Guys know what they’re doing but also super personable, the kind you’d want to grab a brew with after. Could not recommend anyone else! "

A: Aluminum wiring expands and contracts more than copper, causing loose connections, overheating, and arcing. Homes with aluminum wiring are up to 55 times more likely to have fire hazards.
A: Look for silver-colored wires (instead of copper) at outlets, switches, and in the panel. Homes built between 1965 and 1973 are most likely to have it. We offer free inspections to confirm.
A: For maximum safety and long-term reliability, we strongly recommend a full home rewire with copper wiring.
A: Full rewiring typically ranges from $8,000 – $25,000+ depending on home size, number of stories, and accessibility. We provide detailed, transparent quotes after a free on-site assessment.
A: Most single-family homes take 3–7 days. We work efficiently and minimize disruption to your daily life.
A: Yes. All major rewiring requires electrical permits and inspections. We handle all permitting with your local building department.
A: Absolutely. A full copper rewire is a major selling point for older homes and can significantly increase property value and buyer confidence.
A: Yes. We work with several financing partners to make safe electrical upgrades affordable.
New Jersey requires an electrical permit for this work under the Uniform Construction Code. The forms come from the New Jersey Department of Community Affairs and are filed with the township construction office. Integrated Electrical Solutions pulls the permit and meets the inspector. Insurers often ask for proof that the aluminum was repaired by an accepted method. After inspection, IES provides an itemized invoice listing the method used and the number of connections, along with the township's approval. That paperwork is what most underwriters and buyers' attorneys ask for.
