Mystery Door Problem

Lately the front door has become hard and harder to close. It has gotten to the point I'm sure our neighbors knew whenever we entered or exit our home.

So I started looking around the edge of the door to see where the door was hitting first and lo and behold the threshold showed the most wear.

Since it was the threshold the fix is really easy. I simple tighten each screw in  in the door hinge. You have to be very careful not to strip the screw.

And now it is like a night and day difference when closing the door.
