Thanks for the information guys. Having to remove the door is the last thing I wanted to hear, as I didn't need this to be an expensive repair.

Joe, you mentioned about using pressure treated wood instead of brick because it will be covered by the walkway. Wouldn't the brick add an insulating factor to the house that pressure treated wood wouldn't? What are your thoughts on using extruded polystyrene insulation instead, then seal it off with lots of caulk?

The only reasonable argument for owning a gun is to protect yourself from the police.
