One: You need to hire a reputable and reliable moving company. Their expertise and experience will prove to be invaluable when you start moving. They also have several services that is designed to make your move much less stressful and much more efficient. Since they also have insurance, you can be sure that your things are well taken care of.
Two: Pack well. You need to pack room by room so that you can easily unpack room by room as well when you get to your new home, rather than just tossing everything in a box and then taping it up. You'll have to contend with sorting everything out when you unpack, which would be unnecessary and tedious to boot. You should also take care to pack breakable items well, with generous amounts of bubble wrap and packing peanuts.
Three: Make an inventory of your things. You need to make an inventory or list of the things you will be bringing with you so you can better keep track of them when you unpack.
Four: Label your packages. Boxes with fragile items need to be especially labelled - conspicuously - so that whoever handles it will immediately be made aware of the kind of contents in the box.
