Renovation leftover is not household junk. Offcuts, packaging, old cabinetry, and demolition remnants have different disposal paths. Tell the crew what is wood, what is metal, and what is mixed.
The useful moment for a cleanup is between trades, not after the last one has already been delayed. Book the load-out before flooring or paint so the finish has a clear room.
Hazardous leftovers — paints, solvents, some adhesives — do not belong in a mixed construction load. Set them aside. A professional crew will confirm what they can take and what must go to a depot.
