Here's How: Proper Pocket Door Installation Technique
Dear James: I like pocket doors because they save floor space, but they often don't glide smoothly into the wall slot. What is the best method to install one? -- Kevin D.
Dear Kevin: As houses are becoming smaller to lower construction costs and utility bills, interest in pocket doors is making a comeback. They were very popular in the Victorian period houses. Back then, everything was hand-fit without the precise sliding hardware kits available today.
There are several advantages of pocket doors over swinging doors. A swinging door typically requires about 10 square feet of floor area for clearance to open and close it. A pocket door requires none. Pocket doors do not block painting or other wall hangings or decorations when the door is opened. Pocket doors are also convenient for the elderly or the physically impaired to open and close.
As with most home projects, proper preparation and the use of high-quality materials make the difference between a good job and a "homemade" job. The pocket doors in your older homes, for example, probably stick because of door warpage due to moisture changes and just wear of the rollers over time.
Unless you are a very experienced carpenter, you should use a pocket door hardware kit to mount your door. Even most carpenters use these kits themselves to save time. These kits include every piece of hardware and materials you need, other than the door itself.
When you are comparing various kits at your home center store to determine which is best for your needs, look for ones with these features: 1) large (1 inch or bigger) nylon wheels, 2) removable and a jump-proof roller track, 3) access to adjustments without removing the door casing, 4) hangers with three wheels that are self-leveling and 5) side split jambs (narrow studs) wrapped in steel for stability.
If you have trouble finding good-quality pocket door hardware kits, check with these manufacturers for the names of local retail sources of their kits: L.E. Johnson, Knape and Vogt, Lawrence Brothers, and National Hardware.
The first preparation item for your project is to seal the edges of the door that you will be using. Once it is installed, you will not have access to all of the edges. Even if you did a perfect job of creating the pocket and aligning all the hardware, it will rub if the door warps.
A plumb rough opening, where the pocket door will be placed, is key to a smoothly operating door. The rough opening in the wall is usually slightly over two times the width of the door that you will use. It must also be level and not twisted. If the floor is not level, always measure from the highest point. Stretching strings from corner to corner will indicate how plumb the opening is.
The next step is usually installing the track that supports the pocket door. Each hardware kit manufacturer has different instructions, so read them carefully, TWICE. Snap chalk lines below the top plate to make sure that you locate the pocket uprights properly.
Install the narrow side split jambs to create the actual pocket that the door will slide into inside the wall. Complete the wall and finish it with drywall or plaster. Be careful not to drive the nails in too deep or they may pass completely through the side split jambs and scratch the door.
The final task is to mount the pocket door hardware, rollers, etc., and hang the door in place. Install the finishing side jamb and then the top jamb. Use finish screws so that they are easily removed for later access to the door hardware.
