Do you have a door that slowly
opens or closes on its own?
Well, that is called “ghosting” and there is a pretty quick fix. Pull out one of the pins in in the door hinge – normally, if it’s a three-hinge door, pull the middle pin. You may need to tap a screwdriver with a hammer to coax it free. Take it out to your garage and with a hammer rap the shaft of the pin just once. That will put an ever-so-slight bow into it. Drive the pin back into the hinge. The slight bend will create enough resistance that the door won’t swing by itself anymore, and you have taken care of your ghosting problem.
