In the house we have just moved into the previous owners have added a conservatory. The door that was the back door is now an internal door and embded in the wooden door sill is a metal baton jutting upwards about 3/4". This was used to seal the door from drafts and the weather when the door was external but now the door is internal and the kids keep stubbing their toes on the metal.
How can I remove either the metal piece or then entire wooden sill and replace it with an internal, flat door thing??
