Here are general guidelines for what each move type covers. Some moving companies' services may differ; be sure to ask what services are included.
(They load, they drive)
The moving company loads the moving truck, drives your belongings to your new address, and unloads the truck. Some companies will also pack your belongings.
Note: Full-service moving companies require a free in-house, visual estimate in order to provide a quote.
(You load, they drive)
You pack your belongings and load them into a secure container placed in front of your home. The moving company picks up the containers and drives it to your new address. You then unload the container. You may want to consider hiring labor to help unload.
Specialized shippers transport your vehicle(s) to your new address in an open or enclosed carrier. Other services are available: Guaranteed pick up / delivery, terminal-to-terminal and door-to-door delivery options.
