Is Copper Wire Worth Anything from Old House Wiring?
Yes — and often more than you think. If you have recently rewired a house, demolished an old building, or replaced the electrical system in a property, the copper wire you pulled out is not junk. Old house wiring typically contains solid copper conductors with a high copper content, and scrap copper has real market value. The question is not whether it is worth anything, but how much you can get for it — and that depends on how you prepare it.
Why old house wiring is worth recycling
Most residential wiring installed in older homes uses solid copper conductors. Copper is prized in scrap markets because it can be recycled again and again without losing quality, and steady demand from the electrical, construction, and electronics industries keeps prices firm. When you count the branch circuits, the service entrance cable, and the appliance feeds, a single older home can yield a surprising amount of copper. For a homeowner that is a nice bonus on a renovation; for an electrician or contractor who rewires several properties a year, the accumulated value becomes a serious income stream.
How much is old house wiring worth?
Scrap yards price copper wire by grade, and the grade depends on how much preparation you do:
- Bare bright copper — stripped, clean, uncoated wire. This is the top grade and pays the highest price per pound.
- No. 1 copper — clean wire or tubing with no solder, paint, or attachments.
- No. 2 copper — lower purity, with oxidation, solder, or coatings that bring the price down.
- Insulated wire — priced by the estimated copper recovery, and pays far less per pound because the yard must process out the plastic.
As a general guide, clean bare-bright copper has recently traded in the range of roughly $4.65 to $5.45 per pound at U.S. scrap yards, with No. 1 and No. 2 copper sitting just below that. Insulated wire brings much less — often around $1.85 to $3.75 per pound depending on the copper content. In other words, the same copper can be worth two to three times more per pound once the insulation is removed. Keep in mind that prices vary by region, market conditions, and yard policy, so always check current local quotes before selling.
What affects the value of your copper wire
- Insulation: plastic, paper, and rubber add weight but no value. Yards weigh everything, so insulation dilutes your payout.
- Gauge: thick conductors such as 10, 8, and 6 AWG contain more copper per foot and are worth more per pound than thin, fine-stranded wire.
- Contamination: solder, paint, steel connectors, and other metals ｄｒｏｐ the grade and the price.
- Condition: clean, dry, and sorted copper earns top rates, while mixed or dirty material is discounted.
Should you strip the insulation?
Stripping is usually worth it for heavy-gauge wire. Consider a simple example: if 100 pounds of insulated cable sells for $3.45 per pound, that is $345. If the same cable contains 75 pounds of clean copper that sells for $5.45 per pound, stripping it produces about $408 — a gain of more than $60 on a single load. For thin, fine-stranded wire, however, the time and effort of stripping often is not worth the small gain, and selling it as insulated wire is the smarter move.
For a few rolls of wire, a handheld wire stripper is fine. But when you are handling the wiring from a whole house, or running a business that rewires or demolishes buildings regularly, manual stripping is slow and labor-intensive. This is where purpose-built recycling equipment pays for itself.
Turning old house wiring into clean copper
For contractors, electricians, and scrap dealers handling larger volumes, a copper wire recycling machine does the job automatically: it shreds the cable, separates the copper from the plastic insulation, and delivers clean copper granules ready for sale at the top grade. A scrap cable stripper handles thick, heavy cable first, while a cable recycling machine with a dry separator processes the rest into copper and plastic fractions.
San Lan Technologies Co., Ltd is a professional manufacturer of cable recycling equipment with over 15 years of experience in e-waste recycling machinery. Their cable recycling plant range includes compact granulators such as the WCD-100C and WCD-200C for small workshops, high-capacity machines like the WCD-600S and WCD-1200S for larger operations, and complete cable recycling plants for industrial-scale processing. Whether you are stripping the wiring from a single old house or running a full-scale cable recycling business, the right equipment turns low-value insulated wire into high-grade copper that sells at the top of the market.
Final verdict
Yes, copper wire from old house wiring is definitely worth something — and with the right preparation, it is worth a lot more. Sort it, strip the heavy gauge, keep it clean, and sell it by grade. For small amounts, a little manual work pays off. For larger volumes, investing in professional cable recycling machinery is the fastest way to maximize the value of every pound of copper you recover.
