I've got an external upvc door in the kitchen that's got a 1cm gap underneath it.
The old flooring was wood laminate, but this was replaced with vinyl some time ago, which has resulten in a gap.

What's the proper way to seal below a upvc door? Do I need to take the frame out, or can it be done in place (I'm hoping for the latter of course).
If the frame needs to come out, is there a short term solution that will last the winter that's better than my bodge with a bit of wood?
