Make sure they know

Believe it or not, movers do read your labels. When they have moved all of your boxes out of the house they may set them outside the van according to size. Then the driver will direct the movers to bring him the various boxes so that he is able to pack his truck so the weight is evenly distributed. It could cause a problem if they put all of the weight on one side of the truck or all of it at one end or the other. When he has the men bring him the boxes they do see your labels and will stack them accordingly. Be certain you have marked the boxes correctly. If you have a box of crystal glasses at the bottom of a pile of a dozen other boxes filled with books you may only have shards of crystal in the box instead of goblets. Even if you have packed them quite well in a glass pack box they may be too light to support a lot of heavy boxes of books.
After you called your removal company and scheduled your moving date, you will need to get certain things done. So you will also have to call your utility companies to make sure you have light and power and water. You will also need to notify the post office that you have an upcoming change of address. You may also need to let your magazine subscriptions services also know you are moving because some items will not be forwarded. Of course you will notify your bank and credit card companies in advance so they have the correct address to mail their statements to.
It is also important to make sure what internet services you will have if they are different from your current services. It is sometimes surprising how many services we use and business we conduct over the internet so any of those address changes also need to be made.
