Guide Bit For The Guide Groove

Cut the slot. An L-shaped guide mounted to the floor prevents the door from swinging and hitting the wall or the casing as it’s opened and closed. The guide aligns with a groove made with a slot cutter in the door bottom.


Codes and Permits

Interior door installation generally does not trigger the need for a building permit. But to be on the safe side, check with your local permitting department. One of the values of a pair of barn doors is the extra width. So if you need to widen an existing doorway or create a new doorway, you may need to apply for a building permit since this may compromise the wall’s structural integrity.

Tracks And Hardware For All Tastes

Sliding-door hardware has its origins in rustic architecture, but high-style, ultramodern hardware is also available. Hiding the track with a valance also can change the look or help a new sliding door to fit in with existing decor.

Steps for installing a sliding barn door:

  1. The door in the kit comes untreated, so start by applying a desired stain/finish to the door with a rag.
  2. Attach the mounting board over the opening with 4 inch structural screws. Keep a level on the board and loosely screw the board in until it’s roughly in the right place. Once the board is mostly attached to the wall and level, secure all the screws.
  3. Attach the mounting hardware to the mounting board. Again, only secure the bolts loosely until the entire rail has been attached. Then secure them all with a wrench.
  4. Slide the stops onto the mounting hardware. This will ensure the door doesn’t slide off the rail.
  5. Attach the door hardware to the door and hang it in place on the rail.
  6. With the door in position, put the floor guide in the correct position on the floor to help guide the door from the bottom. Mark its location with a pencil.
  7. Remove the door and secure the floor guide to the floor with the drill and some screws.
  8. Rehang the door. With it in the correct position, make sure it’s perfectly over the floor guide.
  9. Add the anti-jump blocks that come with the kit onto the railing to prevent the door from sliding off the rail.

When to Call a Professional

If you need to widen the doorway or create a new doorway in a load-bearing wall, you may wish to hire a contractor to perform the work since additional support must be added. Pulling back and opening walls may also require moving electrical outlets and light switches; you may want to hire an electrician for this work.

Barn Door Wall Decor Ideas

We wanted to install a barn door to replace the door leading into our bathroom. Our room has a cottage farmhouse vintage feel so I didn’t want a new door and I wanted it to serve as a focal point and feel more like wall decor.

I turned to Facebook Marketplace and found an antique door for $35. One side had already been stripped but the other side was chippy white paint. Both sides were really cool and perfect for what we were going for!

The guy told me it was 3 feet by 7 feet but he was off on his measurements. When we got the door home it was too short so we had to add a section on to make it long enough.

At first, I was bummed because I thought I would have to paint both sides since the added piece didn’t match the door. But then I decided to just paint a strip of white on the top where the new piece was and see how it looked.

We ended up loving the look! Dipped furniture is really popular right now and so I took that idea and applied it to the door and it worked well! Now it was ready to hang!

How to Install Double Barn Doors

Installing double barn doors works much the same as a single, you just have a longer rail. You will need to measure the rail to get the length for your header. This time instead of lining it up against the trim, it will need to be centered so it hangs over evenly on both sides of the opening.

As mentioned above, you will locate the studs to screw the header into directly on top of the trim (you can adjust this if your doors are taller). Attach the rail to the header following the directions for your hardware. Refer to previous steps for installing the doors.

Shopping List


  1. Add Mounting Board

    Install a mounting board to the top of your doorway to help hold the weight of the barn door. Align the 1×4-inch board about an inch above the door frame, so there will be a 1/4-inch gap between the floor and the door. The mounting board should be the same length as the full sliding door track. Wherever you place it, make sure the door will have room to slide completely open and closed. This means it should extend past the doorway several inches on one side and several feet on the other (a few inches more than the door is wide).

    Secure the mounting board to the wall with a power drill and interior screws. Before drilling, use a stud finder to make sure you're drilling into the wall studs. This will ensure the strongest attachment for your door hardware.

  2. Install the Track

    You can purchase the track hardware separately or as a kit. We found this affordable option on Amazon that had everything we needed to hang the sliding barn door.

    Before you install the track, you need to measure the door height. Starting at the floor, use a tape measure to record the height of the doorway, then add 1-3/4 inches. (Ours was installed 81-1/4 inches from the floor.) The track should start at least 2 inches off the leading edge of the doorway. Using a level and a partner, hold the track in place and mark screw holes with a pencil. Drill pilot holes with a 1/4-inch bit.

    When installing the track, each screw hole should be aligned with a spacer behind the track. Then the track should be placed, followed by a flat washer and a screw. Repeat on all screw holes.

    Editor’s Tip: Installing the track is a project that requires two people. We strongly discourage this project from being attempted solo.

  3. Install Hangers and Handle

    Lay the door right-side up on a work table or pair of sawhorses. Place the first hanger at least two inches from the edge of the door. The top screw should be 1-1/2 inches from the top of the door. Mark the holes with a pencil. The same measurements should be applied to the hanger at the other end of the door.

    Drill through your pencil marks with a 3/8-inch drill bit. Be sure to also install anti-jump discs to the top of the door, at least 1 inch from the edge of the door. Mount hangers to door with nuts and bolts appropriately sized for your door's thickness. Select where you want the door handle to go and secure with screws.

    Editor's Tip: The standard height of door handles is 36–42 inches from the floor.

  4. Place Door on Track

    Carefully place the door on the track. Once in place, install floor guides following manufacturer's instructions. Slide the door side to side to make sure it runs smoothly.

    Editor's Tip: If you're using a custom door, double-check that the door track is wide enough to account for the sliding panel.
