Pack to suit the access route
Because access can be narrow and conditions can be damp or breezy, robust wrapping and lighter cartons help keep the pace steady. In practice that means lighter cartons for stair carries, stronger wrapping for exposed loading points and fewer oversized boxes that jam in hallways.
Label with the unload in mind
Use clear room labels, mark priority cartons and separate anything that needs two-person handling. Good labels shorten the unload and stop boxes being shifted twice.
Protect what gets handled most
Mattresses, upholstered items and large case goods usually take the most contact on this type of move. Covers, edge protection and sealed hardware bags help them travel cleanly through tighter local access points.
