Concealed draught excluders

[Kell]

Have just had solid oak door fitted and due to problem with the door frame, there is now 10mm gap between the door and the floor. Can anyone recommend how I can bridge the gap without seeing anything sticking out the bottom of the door?

Many thanks

A centimeter, just over three eights of an inch is not very much. Have you checked the whole swing of the door to see if the gap is consistent?
You do need some floor clearence, so you cannot expect to reduce the gap by much.
It seems like a lot of work with little gain.
