I have heard of many people needing to 'shave' a bit off their doors when they get new carpets. Just curious really as to how this works. I would assume a joiner would be necessary but how would the carpet fitter proceed if I don't have a live in joiner and my carpet doesn't fit? Would I be expected to take doors off myself? Would the fitter take them off and leave them for me to then get a joiner? Do they shave them themselves?
