Pocket Sliding Glass Door Systems - Just a couple of months ago I went over to fix a pocket door that was shutting in a weird angle. This was the very first time I'd ran into this sort of scenario and was definitely confused. I got a torch and started looking inside the pocket door frame. I had trouble discovering the problem but when I did it was clear.
As the pocket door was skidding shut it would work perfectly but when you went to open it the base of the door would stick out about an inch and a half passed the door jam. The difficulty turned out to be the track was missing a screw in the very rear so when the door slid back into the framework the tracking would hang down at an angle in the weight of the doorway. There is no way as it was at that back of the pocket door frame near the framing, to achieve the screw.
This was the only real thing I would require a wall patch that is simple and really could think of and some paint to help make the repair complete. Then I use some fiberglass drywall tape and some fast setting drywall plaster to fix the wall. This took another hour to complete the drywall properly.
Some pocket door difficulties are a little easier to fix than this one. Most pocket doors appeared to have difficulties sliding and eventually are left shut, never to be used again. Painting the doors over and over again can actually increase the depth of the door or excessive moisture in the house over long amounts of time can also make the doorway to swell preventing it from opening properly.
