I needed to replace the steel door to the back of the house. I purchased an Identical door which came preset in a frame. The old frame had termite and rot damage on the bottom of the frame so I choose to install the new door with the frame instead of just replacing the door.
The new frame placed in nicely, and after screwing her down, I have to lift the door up, by the door knob, in order to lock the door.
I'm sure this has to be a shim problem, but where would I add the extra shim?
