Pocket doors are a really great space saver and they’ve become extremely popular with today’s floor plans. Pocket doors slide on an overhead rail system that allows the door to be slid into a pocket in the adjacent wall. Pocket doors can even match all the other doors in your home and appear to be a regular door when it’s closed. Installing a pocket door isn’t very difficult but it does require some different trim details.
Trimming Pocket Door Jambs
The trick to pocket doors is trimming the jam on the top and pocket side. Pocket door frames consist of both metal and wood components. One each room side of the pocket side of the frame there is a piece of 1x material that the drywall can be screwed to. This is also the only wood that’s available to attach the jambs and casing to. As you can see in the next photo the pocket side jamb is trimmed out with pieces of 1x screwed to the 1x frame material.
The first step is to rip a piece of 1x trim material to the depth of the frame plus drywall. Typically this is 1-1/4″ wide but it’s best to measure and check the dimension. Next I like to screw the jamb material to the pocket door frame instead of nailing it. I pre-drill the trim and use a small headed trim screw.
On the other side you just install a full width piece of jamb trim from floor to top. If you want you can install a fake jamb stop to mimic a traditional hung door. Once the jambs are installed you can install casing in the same fashion as the regular doors. Just be careful not to use long fasteners as you’ll hit the door in the pocket. I recommend glueing the trim on and using short brad nails.
