If a door isn't closing properly, and the problem seems to be with the hinge side rather than the latch, you can probably fix it with some minor adjustments at the hinges. Sometimes doors weren't originally hung properly, or have shifted over time, and now are binding when you try to close them, or sagging at the part of the door frame that the hinges are screwed into. Depending on the situation,
. you might have to shim the hinges up, or sink them lower by chiseling. You might have to reposition the hinge further back on the jamb so the hinge pins can turn. Or you might just need to sink some longer screws into the existing holes to better secure the door. Learn more at http://www.ehow.com/how_5163154_adjust-door-hinges.html
