My entrance room shifts during fall and winter. Wind comes in around the edges of the door.
I have a quick solution that lasts some times for more that a year.
By putting Duck Tape along the door Stop edge facing the sticky side out this is how it looks.
You can do this any time, even if it is snowing.
Make sure the door stop is dry.
Go all around where you can see light or feel a draft.
It only takes a few moments and when the wind blows , the ducktape is pushed against the door and it stops the draft.
If you use the military strength tape it will last longer.
No one has gotten stuck on it yet, and by summer the sticky side is not sticky any more.
