If your insurance carrier flagged the aluminum branch-circuit wiring in your 1965–75 Columbia home, we'll fix it the way they require. COPALUM connectors, AlumiConn pigtails, or a full rewire — with a signed inspection report your carrier will accept.
From roughly 1965 to 1975, copper prices spiked and builders across the country (Columbia included) switched to solid-conductor aluminum for branch-circuit wiring. A huge swath of Columbia's housing stock from that decade — much of Forest Acres, Spring Valley, parts of Irmo and West Columbia, and most of the original Cayce subdivisions — has aluminum wiring behind the walls.
The wire itself isn't condemned. The problem is at every connection: aluminum expands and contracts more than copper, oxidizes under the screw terminals of receptacles and switches, and over decades the connections loosen and overheat. The CPSC found aluminum-wired homes are 55× more likely to have a fire-hazard connection than copper-wired homes. That's why most major insurance carriers — State Farm, Allstate, USAA, Liberty Mutual, and many regional ones — now refuse to renew policies on un-remediated aluminum homes.
The fix is well-established: address every connection (receptacles, switches, light fixtures, panel terminations) with either a full copper rewire or a CPSC-approved pigtail repair using AlumiConn or COPALUM connectors. We do all three, plus the panel upgrade work if your insurance carrier wants that included too.
Purple King Innovations terminal blocks — CPSC-approved, inspectable, screw-down install. Our default for most Columbia jobs. Fast, NEC-compliant, less expensive than COPALUM.
The CPSC gold standard — AMP-tool crimped copper-to-aluminum splice. Permanent and reliable. Available when an insurance carrier specifies it or you want the highest-end fix.
Focal repair for homes with damage at specific locations (kitchen, laundry, HVAC). Often paired with a panel-side rework so the most heavily loaded circuits get fixed first.
New copper branch circuits throughout — the most disruptive and most expensive option. Worth considering during a remodel or if multiple connections show heat damage.
Signed, photographed, license-stamped report your carrier will accept. Connection count, materials used, NEC-compliance notes. We've handled most major SC carriers' forms.
Many aluminum jobs pair with a panel upgrade to 200-amp service and CO/ALR-rated receptacle replacement. We package it for one permit and one trip.
Most aluminum jobs are concentrated in the 1965–75 Columbia subdivisions — Forest Acres, Spring Valley, parts of Irmo, West Columbia, Cayce, and original Lexington and Chapin neighborhoods. We cover all of the Midlands.
Aluminum branch-circuit wiring isn't dangerous on its own — the risk is at the connections. Aluminum expands and contracts more than copper, oxidizes, and loosens at receptacles, switches, and breakers. Loose connections heat up and can ignite the box. The CPSC found aluminum-wired homes are 55× more likely to have a fire-hazard connection than copper-wired homes. The fix is to address the connections, not necessarily the wire itself.
Many carriers (State Farm, Allstate, USAA, Liberty Mutual, and most regional carriers) now decline to renew or write new policies on homes with un-remediated aluminum branch-circuit wiring. They'll typically accept a completed COPALUM or AlumiConn remediation with a licensed-electrician inspection report. We provide carrier-ready documentation as part of every aluminum job.
COPALUM is a crimped copper-to-aluminum splice using a specialized AMP tool — it's CPSC-recommended as the gold standard, but requires a certified installer and the connection is permanent. AlumiConn is a screw-down terminal block (purple) approved by the CPSC as an acceptable alternative — it's faster to install, less expensive, and inspectable. Both are NEC-compliant when installed correctly. We use AlumiConn for most Columbia jobs because cost-per-connection is lower and homeowners can have the work inspected easily.
Pigtailing every connection (every receptacle, switch, light fixture, and breaker) is enough for most homes and is what insurance carriers actually require. A full copper rewire is more disruptive and 4–6× more expensive — usually only justified if you're remodeling anyway, or if multiple connections show heat damage. We inspect first and tell you straight what's appropriate.
Pigtailing pricing depends on connection count, not square footage. Most Columbia 1965–75 homes have 80–140 connections (every receptacle, switch, and breaker). Per-connection pricing is $25–$45 depending on access. A typical 1,800 sq ft home runs $3,000–$5,500 for full pigtailing with carrier-ready documentation. We quote on-site after a walk-through — no surprises.
Yes — every aluminum remediation we do includes a signed inspection report with photos, connection count, materials used (AlumiConn or COPALUM), and license number. Most carriers accept it directly. If your carrier wants a specific form, we'll fill out theirs too. Same-week turnaround on documentation.
We'll walk the home and quote on the spot.
