There are several things you should avoid:
Putting too many items in each box, as it would render them too heavy for carrying
Making last minute rearrangements – this can only lead to further complications
Assuming that the company you hire will perform everything you consider to be their job. Instead, ask questions and negotiate before you make the arrangement
Not being present at the time of pick-up. If you can’t be there, assign someone you trust, a close friend or family member to be there during the pickup. Even trustworthy experts avoid operating without supervision to avoid liability issues.
Trying to transport hazardous materials. It’s better to leave something behind or drive it in your car than to cause serious issues with your cargo.
