Hi,
I have an exterior metal entry door and noticed that the doorsweep fell off the bottom. When I looked closer, I realized that the interior of the door is made of wood and the bottom INTERIOR frame of the door had rotted out completely and fallen away.

Rest of the door works fine and is solid so, ideally, I would like to just chisel out a little more of the rotten wood from the bottom, and replace with a new piece of wood in order to make it solid again.

Has anyone had similar experience with such a door?
Any pros/cons to repair?
Maybe use treated wood with stainless screws?
Thanks
Theodore
