Before the excavator arrives or the dumpsters fill, the building is holding thousands of dollars in nonferrous metal. This is the crew-level guide to finding it: where the copper wire hides, where the copper pipe runs, which fixtures are brass, and the order that pulls it all out before the debris does.
The trade press has said it plainly: in construction and demolition recycling, the dollars today are in nonferrous metals. Copper, brass, and aluminum carry real weight value, and they come out of every building — houses, offices, plants — as a matter of course. The only question is whether they leave in a salvage bin or a mixed debris load.
This guide is written for the foreman and the crew doing the work. It is organized by system — wire, pipe, fixtures, equipment — because that is how buildings give up their metal. Pull it in order, keep it sorted, and the demo pays for itself twice.
Salvage in pre-1978 buildings requires lead-paint and asbestos testing before you disturb materials — tile, mastic, insulation, and joint compound from that era can contain them, and abatement is licensed work. This guide covers non-structural salvage only: never remove load-bearing elements, and anything electrical or plumbing you disturb must remain code-compliant.
Salvage work must stay code- and law-compliant: anything electrical you disturb must remain code-compliant (NEC 300.15 — splices only in accessible boxes), plumbing you touch must meet the local plumbing code, and pre-1978 structures need lead/asbestos testing before disturbance per federal EPA RRP rules. Check local amendments for demolition permit requirements.
Walk the building with the panel schedule. Pull home runs and branch circuits back to the panels: Romex in residential, THHN in conduit in commercial. Commercial buildings are the prize — long conduit runs of THHN pull out clean and fast, and a single office floor can yield hundreds of pounds of insulated copper. Keep insulated wire separate from bare grounds; they grade differently.
The heaviest copper in any building is the service entrance cable and the feeder runs to subpanels — thick, heavy, and short work to pull once the power is confirmed dead and the utility has disconnected. Panel feeders in commercial buildings run in large conduit and come out in long, clean pulls. This is the wire that makes the trip worthwhile on its own.
Every panelboard holds a copper busbar, and every breaker is a small piece of reusable or recyclable hardware. Pull the breakers, unbolt the busbar, and coil the feeder tails. Old but functional breakers and panels have a second life as used electrical equipment — separate the reusable gear from the pure scrap, because the two streams pay differently.
Trace every water line back to the main: copper supply lines, stub-outs, and risers pull out in long straight sections if you cut them free instead of smashing them. Brass shutoff valves, hose bibbs, and fittings come off with wrenches — brass is brass, and a bucket of valves adds up fast. Do not forget the mechanical room: water heaters, boilers, and softeners all carry copper and brass connections.
The mechanical and electrical rooms are the richest square footage in the building. Motors carry copper windings, transformers carry copper and steel, and busbar runs carry solid copper bar. HVAC units hold copper coils and line sets. Pull equipment intact where possible — a whole motor is easier to handle and grade than a pile of fragments, and compressors and coils stay cleaner for recovery.
Brass door hardware, brass plumbing trim, copper and brass light fixtures, and aluminum window frames and storefront systems all have value. Remove them whole — a brass faucet set removed with wrenches is a clean brass item; the same set pried off with a bar is mangled mixed metal. In commercial buildings, aluminum curtain wall and storefront framing is a major stream by itself.
Wire and pipe hide in the places crews walk past: above drop ceilings, in basement joist bays, in attic runs, and in the walls of kitchens and baths. A flashlight sweep of every ceiling plenum and crawl space before the debris phase catches the runs that everyone forgot — and forgotten runs are pure profit because the labor to expose them is already spent.
Stage the salvage in labeled, separated piles away from the debris flow — once metal hits the mixed pile, its value drops and the sorting labor doubles. Photograph the staged material: type, rough weight, and location. Then call before the dumpsters fill, because every day the metal sits unsold is a day it risks getting buried under debris.
Every one of these has cost someone a callback. Learn them here instead of on the job.
The most dangerous mistake in salvage. Verify dead at the panel and at the device — mislabeled panels are everywhere.
Copper, brass, and aluminum tossed together get the lowest common price. Sorted piles get full value for each metal.
Brass valves, copper fittings, and fixtures removed whole are worth more than the same metal mangled. Wrenches first, saws second.
Wire pulled during demo is free copper. Wire left in the walls goes to the landfill with the drywall — and the crew leaves money behind.
The richest room in the building. Busbar, feeders, motors, and transformers live where the power comes in — do not skip it.
This whole guide is the seed. Every system above ends the same way: copper wire in one bin, copper pipe in another, brass in a third — and a phone call when the bins are full. Before the excavator arrives, before the debris trucks roll, the metal inside the building is worth more than the demo bid line for hauling it away.
