How To Install Bypass Sliding Pantry Doors

Bypass sliding doors are a smart and stylish way to close off your pantry while making the most of your space and keeping your storage easily accessible. In the video above, Ask This Old House carpenter Nathan Gilbert walks through installing bypass sliding pantry doors and shares helpful tips along the way. Below, we’ll dive deeper into how you can complete this do-it-yourself (DIY) project yourself.

What Are Bypass Sliding Doors?

Bypass sliding doors are a popular choice for pantries, closets, and other spaces where traditional swinging doors might be impractical. The doors slide along a track, allowing them to overlap each other when opened. This means they don’t swing outward, saving space in the room. They give you easy access to the entire pantry or closet space and operate smoothly and quietly.

You can style these doors in several ways. The most popular types of bypass sliding doors are flat panel, glass, mirrored, louvered, and raised panel doors:

• Flat panel doors: These doors feature a simple, smooth surface with no decorative elements, making them a versatile option that blends easily with various interior styles.
• Glass doors: Glass sliding doors allow natural light to flow into the space while creating an open, airy feel. They can be frosted or clear depending on your privacy needs.
• Louvered doors: These doors have horizontal slats that allow for ventilation, making them ideal for closets or laundry rooms where airflow is needed.
• Mirrored doors: Mirrored sliding doors serve a dual purpose by providing both a functional mirror and a door, making them a popular choice for bedrooms and dressing areas.
• Raised panel doors: These doors feature decorative, elevated panels that add texture and depth, offering a more traditional and classic look to a room.

Preparing for Installation

Before you start this project, gather all the necessary materials and tools. A bit of prep work will make installation much smoother. You’ll need the following items:

• Bypass door hardware kit
• Interior doors (matching your desired style)
• Primed trim pieces
• Screws and fasteners
• Shims

• Brad nailer
• Drill driver
• Forstner bit
• Level
• Measuring tape
• Track saw or circular saw

Tools

Measuring the Opening

Accurate measurements are key to a successful installation. Measure the width and height of your opening, taking into account any irregularities. In the video, Gilbert shows how to handle an uneven opening by padding out the jambs with extra material. Getting these measurements right will save you from headaches later on.

Pro Tip: Tom Silva, This Old House general contractor, emphasizes the importance of checking the floor for level before proceeding. As he explains: “This is an old house and very seldom are they level. So what I’ll do is I’ll just take my tape measure and I’ll measure down to the floor.” If the measurements differ from one side of the opening to the other, you’ll need to account for that discrepancy — otherwise your header won’t be level and your doors won’t slide properly.

Old houses present unique challenges. As noted in This Old House Magazine, “Just as it’s easier to build a house on a level foundation, it’s simpler to hang a door in an opening that’s level, plumb, and square. While these are rare qualities in most old houses (and an unfortunate number of new ones), the fact that an opening is out of sorts doesn’t mean the door has to be.” The trick is to adjust the opening itself by shimming or padding out the jambs — exactly the approach Gilbert demonstrates here.

Installing the Track

The track is the backbone of your bypass sliding door system. Mark where the track will go at the top of the opening, and use a level to make sure it’s perfectly straight. Mark the screw holes for mounting the track. Drill pilot holes at the marked spots, attach the track with the screws provided in the hardware kit, and check for level again. Use shims for any adjustments. 

Preparing the Doors

Getting the doors ready before hanging them will give your project a polished, professional look. If needed, trim the doors to fit the opening. Measure from the floor to the track, subtract 1/2 inch for clearance, and mark the doors. Use a track saw or circular saw to cut them to the right height. Attach the roller hardware to the top of each door, positioning the rollers about 1 inch from each edge. Secure the rollers with the screws provided, making sure they’re level and aligned.

Prevent Chipping When Cutting: Before trimming a door with a circular saw, apply painter’s tape along the cut line, then score the line with a utility knife. This keeps the saw blade from chipping the wood veneer or finish, ensuring a clean edge. With the saw braced on a cutting guide and the blade on the waste side of the line, slowly trim the door to size.

Hanging the Doors

Now that the track is in place and the doors are prepped, it’s time to hang them. This step involves getting the doors to slide smoothly and line up correctly. Lift the first door and insert the rollers into the track. Repeat the process for the second door, and test them to make sure they slide smoothly. To install a floor guide, position it in the center of the opening and check that both doors fit into the guide slots. Secure the guide to the floor with screws.

Finishing Touches

With the doors installed, it’s time to add the final touches to make everything look and function just right:

• Adding door pulls: Install finger pulls for easy operation. Mark where you want the pulls on each door, drill holes with a Forstner bit, and install the pulls following the manufacturer’s instructions.
• Installing trim: Add trim to cover the track and give the opening a finished look. Cut the trim pieces to fit, secure them with a brad nailer, and fill any nail holes before painting to match your decor.
• Making final adjustments: Double-check that everything is aligned and working smoothly. Make any necessary tweaks to the rollers or track for the best performance.

Positioning Door Pulls: According to This Old House Magazine, if your doors are flat, measure 36 inches up from the floor on each leading door and mark the center, side-to-side, at that height. If the door is paneled, find the center of the middle rail instead—this will look better. Hold a straightedge diagonally from corner to corner on the rail, make a small line in the middle, then switch to the other diagonal and cross the line. The X marks the rail’s center. Drill 3/16-inch holes at each mark and screw on door pulls.

Hiding the Track with Trim: This Old House Magazine recommends cutting a piece of 1×2 stock the width of the opening to fit in front of the track and conceal it. Prime the trim and let it dry, then drill pilot holes through the underside of the trim into the header using a 1/16-inch bit. Secure the trim to the header with trim screws, then fill the screw holes before painting.

Maintenance and Care

A little maintenance will keep your bypass sliding pantry doors working smoothly for years to come. Here’s what you can do:

• Regular cleaning: Keep the track clean by removing debris periodically. Dust the doors and track weekly, and wipe down the doors with a damp cloth as needed.
• Lubricating the track: Apply a silicone-based lubricant to the track every 6–12 months to maintain smooth operation. Wipe away any excess to avoid dirt buildup, and test the doors to make sure they slide easily.
• Inspecting hardware: Regularly check all hardware components for wear or damage. Replace any worn parts to keep your doors functioning and safe.

Our Conclusion

Installing bypass sliding pantry doors is a practical and stylish way to improve your home’s storage. With the right tools and materials, and some patience, you can take on this project. The result is a sleek, space-saving pantry door that enhances both the function and look of your kitchen. 

Resources

Gilbert installed two JELD-WEN Colonist Primed wood interior doors that most closely matched the dimensions of the opening. He recommends ensuring the door has not been pre-hung and does not have bore holes in it for a standard knob. These doors can be found at home centers.

To make the doors bypass, Gilbert mounted a Bypass Door Hardware kit, which is manufactured by Johnson Hardware. The kit comes with all the hardware required to mount the doors.

All the other tools and materials required to install these doors can be found at home centers.
