Wow! Thanks for all of your help.
Let me explain gaps - I continually get gecko's coming in that door. In the morning when I wake up and open the blinds, there is yet another gecko either inside the screen or inside my house on the door. The door is shut all night!
I love to watch the little critters but this is starting to become unnerving to me and therefore needs to be fixed.
Replacing the door is a last resort, but I think I am reaching the end of my rope.
