@Teresa1585 Yes, of course you can insist that a qualified person does it. But depending on how the door needs to be installed, it might be a simple thing that almost anyone could do, like if it's just a matter of unscrewing the hinges and screwing the new door onto them. I'd be more concerned about him damaging the floor by scraping the new door on it while trying to hang it.
Honestly, a guest who breaks things because he can't control his anger is a guest whose booking I would seriously consider trying to cut short.
