For anything important at all, do it yourself.
I once hired a seperate removal firm, specialists in piano removal, to shift my piano rather than trust the normal removal folk with it.
I warned them it was an extremely heavy piano, told them it's one which had been specially made from a cast iron Bluthner frame inside a heavy Welmar casing. They should have known from those makes that it weighs a lot more than most pianos.
They sent a couple of scrawny teenagers who couldn't shift it at all. :thud: :thud:
They had to phone in asking for a couple of far more musclebound Mr. Universes to come and help. Even they struggled with it.
