Wonder if any of you have experience installing rubber weather strips on the
bottom of front doors. The finish carpenter that did our front door notched
a channel on the bottom of our front door and installed a rubber strip unit.
There is a metal flashing screwed the the face of the door and nothing on
the inside. the threshold is aluminum. From the side when the door is open
you can see the channel. Is this normal? I have another smaller entry
door that is to a home office type room that he put a unit on the slips
onto the bottom of the door and screws onto the face and inside of the door.
He said he did it that way because it was the front door and cosmetically it
is not normal to have a strip screwed along the inside bottom of the door.

I am just concerned that if the bottom of that front door that he notched
ever rots I have a problem. I would guess that the notch is maybe 1/4"
-3/8" and probably about 3/4" in depth running the bottom of the door.
Maybe I am thinking ahead of myself but I would have preferred the trim
plate on the bottom inside of the door than to alter the door. Also, how
does one even replace the rubber strip on such an installation without
removing the door and flipping it over. I am assuming on the other type, it
just screws and pulls off. Any advice or help would be appreciated. Which
is a more normal type of installation?

I am also concerned if I ever need to replace the door that iw will be
involved and costly. If the door ever has to be replaced it would be a
nightmare as I have had a mortise lock installed, expensive procedure. And
I am assuming that installing a new lock on a new door would require filling
in the jam and redrilling and mortising all holes for the latches.

I guess that channel can be filled at some point if I ever wanted to put a
different type of rubber stripping on it but what a pain.
