Hanging Double Pocket Doors - Just a couple months ago I went over to fix a pocket door that was shutting in a peculiar angle. This was the first time I had ran into this kind of scenario and was definitely lost. I got a torch and started looking in the pocket door frame. I had difficulty discovering the problem but when I did it was clear.
The bottom of the door would stick out about an inch and a half passed the door jam, as the pocket door was sliding shut it would work flawlessly but when you went to open it. There is no method since it absolutely was at that back of the pocket door frame close to the framing to reach the screw.
This was the only thing I could think of and would require a wall patch that is simple and some paint to really make the repair complete. This job took me about one hour to cut the hole and replaced the screw that had fallen out of the pocket door path. Then I use some quick setting drywall plaster plus some fiberglass drywall tape to repair the wall. This took another hour to complete the drywall correctly.
Some pocket door troubles are a little easier to fix than this one. Most pocket doors seemed to have troubles falling and eventually are left shut, never to be properly used again. Painting the doors over and over again can actually increase the thickness of the door or excessive moisture in the house over long periods of time can also cause the doorway to swell keeping it from opening correctly.
