There are many interstate movers who will also pack your things. This is an extremely nice service, but you have to remember that they don’t know or care about your things nearly as much as you will. The workers themselves are also probably being paid very little. The good thing is that they are professionals and will know better how to pack. If you are packing yourself, you have to remember that moving from state to state is a lot more dangerous for your belonging than an in-town move. Your interstate movers will need to know which boxes to handle with care. That means that when you pack your delicate belongings, you must mark the box properly. First of all, pack the box with plenty of padding. If something is important, try to pack these things so securely that a dropped box won’t mean that all of your things will be smashed to pieces.
It also helps if you know exactly where you’re moving. Most movers will give the estimate based on mileage and things like whether or not they will have to move up and downstairs. It also helps to ask around to others who you might already know has moved from another state.
