Although the door frame is hung properly and is square, and the door is square, the space between the bottom of the door and the frame on the hinge side widens at the top. It is like the weight of the door is pulling on the top hinge. You can actually feel the stress on the hinge, feeling the the opposing sides off the hinge moving in and out. I even replaced the hinges. This condition causes the door to hit on the opposite frame. How do I overcome this problem?
