Johnson Pocket Door Rough Opening - Just a few months back I went over to fix a pocket door that was shutting at a weird angle. This was the very first time I'd ran into this type of situation and was undoubtedly lost. I got a torch and began looking within the pocket door frame. I had trouble finding the issue but when I did it was evident.
The problem turned out to be as the door slid back into the frame the tracking would hang down at an angle in the weight of the doorway and the track was missing a screw in the back. There clearly was no way because it was at that back of the pocket door frame close to the framing itself to attain the screw.
This was the only thing I could think of and would require a simple wall patch and some paint to make the repair whole. This job took me about one hour to cut the hole and replaced the screw that had fallen from the pocket door path. I then use some fiberglass drywall tape and some fast setting drywall plaster to repair the wall. This took another hour to complete the drywall correctly.
Some pocket door problems are a little more easy to fix than this one. Most pocket doors appeared to have problems sliding and eventually are left closed, never to be used again. Painting the doors over and over again can actually add to the depth 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 periods of time.
