The time savings and ease of move are tremendous with a professional mover.The cost can vary greatly, depending on whether you include packing/unpacking, insurance limits & what company you choose.
Most companies offer references and free estimates. A binding estimate holds both you & the company to the price quoted; a physical inspection is usually necessary. A non-binding estimate is an approximation of costs; federal law requires a limit of no more than 10 percent additional charges.
Many companies will guarantee pickup and delivery dates; if you're in a time crunch, this may be the only way to go.
