I saw the threshold I need at a hardware store today. It's for an
external
door and comprises of a piece of wood the width of the door and a
piece of
metal to stick out as a kind of step. There are screws in the wood to
raise
or lower the threshold to meet the bottom of the door. If I had know
that
they were for that, I would have raised the threshold on our own door
years
ago to prevent the damp getting in and causing the wood to rot.

Anyway, if those screws are for raising and lowering the threshold
(and not
screwed into the slab like I thought), how is the threshold held in
place.
There's plenty of caulk around where it meets the door jambs but how
is it
actually held to the slab?


Sounds like the ones I installed last year. If it is, you remove the
piece of wood that is raised and lowered, and under there are some
screws, or at least that's where you attach it using plastic or lead
shields, or whatever is needed for what you're going into. That way the
screws are hidden.

Get 3-fin rubber sweep, and you'll never have a draft or moisture. The
wood acts as a thermal break.
