Plenty of people who move themselves are so relieved to arrive that they barely mind a chipped plate or a scratch on the table. You will mind later. Packing is where those marks are usually made or avoided.
Use proper boxes, not ones that have already been rained on. Fill empty corners so contents cannot slide. Put heavy things in small boxes and light things in larger ones. Wrap glass separately and never under a stack of books.
Screens, printers and anything with a tray or a head that can snap should travel in their original packaging if you still have it, or with the same kind of support a shop would use.
If you would rather not spend the week in newspaper and tape, NorDecco Mudanzas can pack piece by piece as part of our services. If you need help with the move, call Jesus on +34 657 484 863 or use our contact form.
