Closet Mirror Pocket Doors - Just a few months back I went over to fix a pocket door that was closing at a weird angle. It was the very first time I had ran into this sort of scenario and was definitely confused. I began looking inside the pocket door frame and got a torch. I had trouble finding the problem but when I did it was apparent.
As the pocket door was slipping shut it would work flawlessly but when you went to open it the bottom of the door would stick out about an inch and a half. The trouble turned out to be the track was missing a screw in the very back so when the door slid back into the frame the tracking would hang down at an angle from the weight of the door. There clearly was no solution to achieve the screw because it absolutely was at that back of the pocket door frame close to the framing itself.
It was the sole thing I would require a simple wall patch and could think of and a few paint to make the repair complete. I then use some fiberglass drywall tape and some fast setting drywall plaster to repair the wall. This took another hour to finish the drywall correctly.
Some pocket door troubles are a little easier to fix than this one. Most pocket doors appeared to have troubles sliding and eventually are left shut, never to be used again. Painting the doors over and over again can actually add to the depth of the door or excessive moisture in the house over long amounts of time can also cause the door to swell preventing it from opening correctly.
