There are two options. We have a binding estimate, or a binding cost of these services specified in advance, that will give you the cost of the move, and then we have a non-binding estimate. A non-binding is used when you're not exactly sure what's moving. For example, you may not know yet if your daughter's going to move with you, or if the things in the garage are going. Non-binding leaves options open, but there could be additional charges if the weight goes higher than anticipated.
