Introduction

Sliding doors are available both finished and unfinished, and in solid and hollow core options. It will make installation much easier if unfinished doors are finished before installation. Replacing closet doors is fairly straightforward. You need to lift the doors off of the track, and then attach the hardware to the new doors. If you have built a new closet and are hanging sliding doors for the first time, you will need to follow all of the steps below.

Step 1

Build the Frame

Measure the door opening. Cut the door frame to length. Lay out the pieces making sure they are square. Nail the frame (Image 1).

Set the frame inside the opening. Use a level to ensure the legs of the frame are plumb (Image 2). Insert shims to adjust and provide a nailing surface.

Use the level to check the top piece of the frame (Image 3). Insert shims to adjust and provide a nailing surface.

If you have made any adjustments, check to make sure the frame is level and plumb. Nail or screw through the shims to attach the frame in place (Image 4).

Step 2

Trim the Door

Measure the door opening; add in the track dimension. Measure and trim the door to fit. Score the door's bottom with a utility knife (Image 1).

With the door on a level surface, use a circular saw to trim the door to length using the score mark as your guide (Image 2).

If the cut end of the door is not perfectly smooth, you may want to plane the surface. Use slow, even pressure on the door, removing material gradually from the surface (Image 3).

Step 3

Install the Door Brackets and Rollers

Using the hardware provided by the manufacturer, attach the top track to the door frame according to their instructions (Image 1).

Mount the brackets and rollers on the upper end of the door, make sure the hardware will not interfere with the movement of the rollers (Image 2).

Set the door rollers inside the top track and hang the door in place. Repeat for the second door (Iamge 3).

Check to make sure the doors are plumb and level. Make any needed adjustments with the roller and bracket hardware (Image 4).

Step 4

Install the Floor Guides and Door Hardware

Attach the floor brackets according to the manufacturer's directions (Iamge 1). Check to make sure the doors can easily move through the opening.

Install the door hardware (Image 2). Sliding doors typically have hardware inset inside the door to allow for easy movement.
