How hard would it be to take back door off hinges (removing hinges from frame, not door) and put it back on again? We're hopefully moving soon and our american fridge freezer doesn't fit through back door without taking its doors off, which I'm not sure removal men will do & we could do it, but I'm not sure how easy would be to do with a 4yo underfoot. Would we be able to take door off the frame and pop it back on again fairly easily? It's only a wooden door, and isn't especially heavy duty (half glazed and the bottom panel is not thick if the hole for the cat flap is anything to go by!
