36 Double Pocket Door - Just a couple months ago I went over to fix a pocket door that was closing in a weird angle. It was the first time I had ran into this type of scenario and was undoubtedly lost. I began looking in the pocket door frame and got a flashlight. I had difficulty finding the problem but when I did it was apparent.
The bottom of the door would stick out about an inch and a half, as the pocket door was sliding shut it would work perfectly but when you went to open it. There clearly was no approach because it was at that back of the pocket door frame close to the framing to reach the screw.
It was the only real thing I would require a wall patch that is simple and could think of plus 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. I then use some fiberglass drywall tape and some quick setting drywall plaster to mend the wall. This took another hour to complete the drywall correctly.
Some pocket door troubles are a little more easy to fix than this one. Most pocket doors seemed to have troubles sliding and eventually are left shut, never to be used again. Painting the doors over and over again can actually increase the thickness of the door or the doorway to swell preventing it from opening correctly can be also caused by excessive moisture in the house over long amounts of time.
