How to Build a Barn Door: DIY Made Easy

Thinking about how to build a barn door and add a sliding one to your home? It’s a great way to save space while giving your room a stylish, rustic feel. 

Whether you're working with a tight area or just want something unique, building your own door is a fun project that lets you control the design and cost. Why not give it a go?

Why Choose a Sliding Barn Door?

Before we dive into the nitty-gritty of construction, let's explore why a sliding barn door might be the perfect addition to your home:

  1. Space-saving marvel: Unlike traditional swing doors, barn doors slide along a track, making them ideal for tight spaces or areas where you want to maximise floor space.
  2. Stylish statement piece: Barn doors add a unique, rustic flair to any room, instantly becoming a focal point and conversation starter.
  3. Versatile design: You can customise your barn door to match any décor style, from farmhouse chic to modern industrial.
  4. Cost-effective solution: Building your own barn door can be more economical than purchasing a pre-made one, especially if you're handy with tools.
  5. Satisfying DIY project: There's nothing quite like the pride of creating something with your own hands and seeing it in use every day.

Step-by-Step Guide: How to Build a Barn Door

Let’s break down the process step by step. 

This is a two-day project. On Day 1, you’ll focus on building the door (Steps 1–10). Day 2 is all about hanging it up (Steps 11–13). Before starting, be sure to measure your door’s width, including the casing. 

Order a track that's double this width to ensure smooth DIY barn door installation.

Cut List for Your Sliding Barn Door

This door will cover a 30-inch-wide opening with a 4-inch casing, measuring 38.5 inches wide, 2.25 inches thick, and 83.5 inches tall.

  • Back boards: Use 1x6 pine, cutting them a half-inch shorter than the door height so it clears the floor guide.
  • Blocking: Cut 1x3 strapping to the work surface width (ours was 48 inches), and cut the rest for blocking.
  • Filler strips: Use 1x5 pine. Cut three rails (38.5 inches wide) and four stiles (35 inches for the upper panel and 34 inches for the lower) to fit between the rails, leaving a 1-inch gap for the floor guide.
  • Pallet boards: Assemble 60 boards, at least 24 3/8 inches long, with 45-degree mitered ends.
  • Face frame: Cut 1x6 cedar into two stiles (83.5 inches tall) and four rails (27.5 inches). Glue and clamp two rails to form the bottom one, then trim 2 inches from one edge after drying.
  • Mounting rail: Cut a 1x4 pine to match the track length (ours was 77 inches).

Now, you’re ready to begin building!

Step 1: Put the Boards Together

Let’s start by getting your boards lined up. For a 30-inch-wide door, seven 1x6 boards should fit perfectly, but you may need to trim them a little.

Measure the height from the floor to the top of the casing. Cut your boards with a mitre saw, making them about half an inch shorter. Lay them side by side, keeping them tight with clamps, ensuring accurate barn door measurements.

Use blocking at the top and bottom to hold them straight, then fasten everything securely with screws. Once everything’s tight and square, you’re ready for the next step!

Step 2: Attach the Filler Strips

Now it’s time to add the filler strips. First, cut your 1x5 strips using a mitre saw, based on the cut list.

Apply some adhesive, then place the top rail flush with the top edge of your boards. Next, attach the upper stiles just below it, making sure they’re flush with the edges. Add the middle rail underneath. 

For the bottom section, position the lower stiles and rail, leaving a 1-inch gap for the floor guide. Secure everything with 1 ¼-inch screws, driving them through each strip into the 1x6 boards underneath. 

Step 3: Create the Chevron Pattern

Start by marking a centreline down the door’s inset panels. Set your mitre saw to 45 degrees and trim the end of each pallet board.

Beginning at the top, join two pieces at the centreline, aligning their angled ends to form a chevron shape. Use a square to mark the boards just shy of the edges, then cut them to size. Do a dry fit to check the alignment before moving on.

Repeat the process, one chevron at a time, until the pattern is complete.

Step 4: Trim the Corner Pieces

For boards reaching the corners, mark where they overlap the stiles and rails using your square. Cut the necessary angles with the mitre saw. After placing the longer pieces, fill in the remaining gaps with scrap wood, cutting each piece to fit neatly into place.

Step 5: Secure the Chevron Pattern

Once your chevrons are in place, take out one pair at a time. Apply some panel adhesive underneath, and press them back into position. 

Secure the boards using a nail gun with 1 1/4-inch brads—place a nail near each corner of every board. Continue this process, gluing and nailing the pairs as you move along both panels.

Step 6: Drill the Pocket Holes

Next, cut the cedar pieces according to your cut list. Lay them rough-side down, covering the filler strips. Attach a pocket hole jig to the end of the rail, aligned with one edge, and drill the pocket holes using the bit from your kit. 

Repeat on the other side. Drill two holes for the top and middle rails and three holes for the bottom one.

Step 7: Assemble the Frame

To put the frame together, apply some wood glue on the ends of the rails and the sides of the stiles. Clamp it securely, then drive screws into the pocket holes on the stiles. Remove the clamps once the frame is sturdy and set.

Step 8: Fix the Face Frame in Place

Start by carefully lifting the face frame and setting it aside. Apply panel adhesive in a zigzag pattern over the filler strips. Now, flip the frame so the rough side is facing upwards, covering the screws. 

Lay it back down, ensuring it aligns with all the edges. Once everything is in place, secure it by nailing 1 1/4-inch brads along the edges, spacing them about 8 inches apart.

Step 9: Apply the Finish for a Smooth Look

First, give the entire door a light sanding using 100-grit sandpaper to smooth out any rough spots or splinters. 

Once sanded, grab a cotton cloth and generously rub paste wax over the surface. This will not only protect the wood but also bring out its natural beauty. Keep rubbing until the wax is fully absorbed, and the door has a nice, even finish.

Step 10: Attach the Rollers to Get Things Moving

Start by positioning the roller hardware in the middle of the door’s cedar stiles. For easier handling, you can take off the wheels. Mark where the screws will go, and using a 1/8-inch bit, drill small pilot holes into the edge of the filler strips. Next, screw the hardware securely into place. 

Once done, reattach the wheels and slide the track into their grooves. Measure the gap between the door and the track to decide how high above the casing the track should be mounted—it’s usually around 3/4 of an inch.

Step 11: Secure the Mounting Board

Cut a 1x4 board to match the length of the track. If you want, you can paint it to blend with your wall. Use a stud finder to locate the wall framing above the door and mark these points. 

Hold the mounting board level above the door casing, and drill pilot holes through the board and into the studs using a 1/8-inch bit. Once everything is aligned, secure the board in place with 3-inch deck screws. This will create a strong base for your sliding door track.

Step 12: Install the Track for Your Barn Door

Start by measuring 3/4 inch above the door casing and marking two spots on the mounting board. Position the track against the board, aligning its bottom edge with your marks. Use a 2-foot level to ensure it's perfectly horizontal. Mark the spots where the lag bolts will go. 

Remove the track and drill 5/16-inch pilot holes at each mark. Insert a lag screw with a standoff through one hole and tighten it partially with a 3/8-inch socket wrench. 

Secure the remaining lag screws, then tighten all of them properly. This setup will provide a solid base for the door to glide smoothly.

Step 13: Hang the Barn Door on the Track

Start by attaching a doorstop at one end of the track. With someone helping, lift the door and carefully place it onto the track. Slide it until it reaches the first doorstop. Next, fix the second doorstop in place. Position the L-shaped floor guide to keep the door steady both when it's open and closed. 

Mark where the screws will go, drill pilot holes, and then fasten the guide to the floor with the screws provided. Finally, mount the door handle on the centerline of the door’s stile. Drill 1/8-inch pilot holes and attach the handle using the supplied hardware.

Additional Tips for a Successful Sliding Barn Door Installation

When setting up your sliding barn door, keep these extra tips in mind:

  • Finishing Choices: You can go beyond just paste wax. Consider staining or painting your door to perfectly match your room’s style.
  • Quality Hardware: Opt for high-quality sliding hardware. Investing in good mechanisms will make sure your door moves smoothly and lasts longer.
  • Accurate Measurements: Always double-check your measurements. Precision is key to ensuring everything fits and operates correctly.
  • Safety First: Don’t forget to wear safety goggles and ear protection when using power tools. It’s all about keeping yourself safe while working.
  • Wood Selection: Pick high-grade barn door wood types. It will give you a more durable and attractive final product.

Troubleshooting Tips

Even with careful planning and execution, you might encounter a few hiccups. Here are some common issues and how to address them:

  1. Door doesn't slide smoothly: Check that the track is level and that the hangers are properly aligned. Adjust as necessary.
  2. Door doesn't fully close: Ensure your door is wide enough to cover the entire opening. You may need to add a thin strip of wood to the edge for a better seal.
  3. Door feels unstable: Double-check that all screws and bolts are tightened securely. Consider adding additional bracing to the door if needed.
  4. Gaps around the door: Install weather stripping or a brush seal to minimise gaps and drafts.

Maintenance and Care

To keep your barn door looking and functioning its best:

  1. Regularly dust and clean the door and track.
  2. Periodically check and tighten any loose hardware.
  3. Lubricate the track and rollers annually with a silicone-based lubricant.
  4. Touch up the finish as needed to protect the wood and maintain its appearance.

Design Ideas to Personalise Your Barn Door

Now that you've mastered the basics, why not get creative with your barn door design? Here are a few ideas to inspire you:

  1. Chevron pattern: Create a striking visual by arranging thin boards in a V-shape pattern.
  2. Chalkboard paint: Turn your door into a functional message board with chalkboard paint.
  3. Glass inserts: Add small windows to your door for a touch of elegance and to allow light through.
  4. Mixed materials: Combine wood with metal accents for an industrial-chic look.
  5. Colour pop: Paint your door in a bold, contrasting colour to make it a true statement piece.
