This procedure includes guidance on repairing a pocket door that is not plumb by shimming the doors, or by shimming the track or rollers to make the doors meet properly.
1. When pocket doors are out of plumb and both slope in same direction, the problem is usually caused by differential settlement between the exterior and interior walls of the building. This problem cannot be repaired. However, the doors may be
rendered usable.
2. If double pocket doors have a space between them which is wider at the bottom, the floor is sagging. If the space is wider at top, it is due to building settlement. If floor sag or building settlement is not severe or dangerous, the pocket doors or track
can be modified to improve the situation.
SYSTEM DESCRIPTION
A. A pocket door assembly in good working condition is free from decay and structurally sound. It is effortlessly smooth sliding and properly aligned. The pocket doors stop precisely when closed and are easily retrieved from pocket. The door latches crisply and should not rattle between latch and stops when closed.
MATERIALS
A. Hardwood blocking for shims
B. Metal angle to replace stop (if needed)
C. Hardwood to match door for finished wedge
EQUIPMENT
A. Carpenter's tools for shimming and for finishing wedge
EXECUTION
For Two Doors that Slope in the Same Direction:
1. Shim out or replace top guide if it is unable to keep uphill door from sliding past center.
2. Restore existing latch or add new latch to keep doors closed.
3. Cut a hardwood wedge to hold uphill door closed and downhill door open.
For Gaps Between Double Pocket Doors:
1. If the space between doors is wider at bottom, shim the bottom track up in center. NOTE: KEEP IT TO A MINIMUM AS THIS COULD CAUSE PEOPLE TO TRIP ON THE HIGHER SURFACE.
-OR-
Insert shim between roller case flange and bottom of door. NOTE: SHIM ONLY THE ROLLER CLOSEST TO
CENTER. SHIM SIDES OF SHEAVE DIFFERENTLY SO THAT SHEAVE IS PARALLEL TO EXISTING FLOOR TRACK. TAKE CARE SO THAT LARGE GAP IS NOT LEFT UNDER DOOR.
2. If space between doors is wider at the top, shim bottom track out toward pockets and/or shim between roller sheave and door, at roller closer to pocket
