Sliding Barn Door Installation — Header Board, Track and Hardware
A barn door is a hundred pounds hanging on two wheels. It has to be on a track that is level and screwed into wood, or it drifts, rattles and pulls out of the drywall. We install it so it stays put.
JMB Builders does barn door installation across the Twin Cities metro, with your door and hardware or ours. We find the studs, mount a header board so the track is fastened into framing instead of drywall, set the track level, hang the door with the hangers and stops, add the soft-close and anti-jump pieces, and set the floor guide so it slides straight. Priced per door, quoted from photos within one business day.

Barn doors look simple. The failures we get called to fix are simple too: a track lagged into drywall that pulled out, a door that rolls open on its own because the track is not level, a door that does not cover the opening because it was bought the same width as the doorway, and a floor guide that was skipped so the door swings and scrapes the wall. All of that is install, not product.
We mount a header board across the wall first, screwed into every stud, then hang the track on the header. That puts every lag into solid wood and gives the track a straight, level surface even on a wavy wall. The door hangs off the track with the stops set so it stays centered on the opening when closed and clears the casing when open. Soft-close, anti-jump blocks and a floor guide finish it. The result is a door that slides with one finger and stops where it should.
What you supply
- The door if you are buying it: at least two inches wider than the opening including casing, tall enough to cover the head casing
- The hardware kit if you are buying it: track at least twice the door width, hangers rated for the door weight, stops, floor guide
- Wall clearance: nothing on the wall where the door parks (light switches, outlets, art)
- Your paint or stain color for a door that comes unfinished, if we are finishing it
What JMB supplies
- Door and hardware on request, added to the quote at cost plus pickup
- Header board in a finished 1x or 2x, sized to the track length and screwed into every stud
- Blocking behind the drywall when the studs do not line up with the track holes
- Track set level, hangers and stops installed, door centered on the opening
- Soft-close dampers, anti-jump blocks and a floor guide set to the door thickness
- Removal of the old swing door and patching of the hinge and strike mortises in the jamb
- Photos of the finished door in your job folder
- Painting or staining an unfinished door when you want it done, quoted as its own line
How it is priced: per door
Quoted in writing from your photos within one business day. What moves the number:
- Single door vs. a double (bi-parting) pair on one long track
- Whether you supply the door and hardware or we do
- Header board length and whether the studs line up or blocking has to go in behind the drywall
- Door weight: a solid slab or glass door needs a heavier track and more careful hanging
- Bypass track for two doors on one opening, or a top-mount vs. face-mount hanger kit
- Removing an old swing door and filling the hinge and strike mortises in the jamb
- Adding a privacy latch or a pull on the back side
Send a straight-on photo of the wall with a tape across the opening, showing the casing and anything on the wall to the side where the door will park.
How long it takes
One barn door with a header board: two to three hours. A double door or a bypass pair: half a day.

Situations and options
Single barn door over a doorway
The standard job: one door, one track, a header board. The door needs to be wider than the opening plus casing so it covers the gap, and the track twice the door width so it can slide fully open.
Double (bi-parting) barn doors
Two doors on one long track that meet in the middle, for a wide opening between rooms. Each door covers half the opening plus an overlap, and the track is roughly twice the opening width. Center stops keep them from crashing.
Bypass barn doors for a closet
Two doors on a double track that slide past each other, for a closet with no wall space beside it. The doors overlap so the closet is closed with no wall to park on.
Fixing a barn door someone else hung
Track pulled out of drywall, door rolling open on its own, door too narrow for the opening. We add a header board, re-level the track, and either move the stops or tell you what size door will actually cover the opening.
Sliding Barn Door Installation — Header Board, Track and Hardware: questions, answered
How wide should a barn door be compared to the opening?
At least two inches wider than the opening measured to the outside of the casing, and most look better with two to three inches of overlap each side. A 32-inch doorway with 2-1/4 inch casing is about 37 inches wide with trim, so a 42-inch door is typical. Height should clear the floor by about a half inch and cover the top casing. A door the same width as the doorway leaves a gap at both sides and never looks closed.
Do you need a header board to install a barn door?
We always use one. The track has to be fastened into solid wood, and the pre-drilled holes in the track rarely line up with studs. A header board, screwed into every stud across the width of the track, turns that into a solid, level mounting surface. It also lifts the track off the wall enough for the door to clear the casing. Without it, lag screws into drywall or a single stud pull out with use.
Can I install a barn door on a wall with a light switch?
Only if the switch is not where the door parks. A barn door sits about an inch off the wall, so it will hit a switch plate or outlet cover on the parking side. Before you buy the door, look at the wall to the side of the opening: it needs to be clear for the width of the door. If a switch is in the way, an electrician can move it, or the door can be hung to slide the other direction.
Does a barn door need a floor guide?
Yes. Without one the bottom of the door swings, scrapes the wall and baseboard, and rattles. The kit usually includes a small floor guide that screws to the floor under the door's parked position, or a wall-mount guide that rides in a groove cut in the bottom of the door. We set it so the door runs straight without binding, and we prefer the wall-mount type where the flooring should not be drilled.
Do you install soft-close on barn doors?
Yes, if the kit includes it or you want it added. Soft-close dampers mount on the track and catch the hanger at each end so the door glides to a stop instead of slamming into the stop. They are worth it on any heavy door and any door a kid will use. Most hardware kits sold now either include them or offer an add-on that fits the same track.
Are barn doors private enough for a bathroom or bedroom?
Not the way a swing door is. A barn door sits off the wall with gaps at the edges, so sound and light get through, and it does not lock without a separate privacy latch. For a bathroom or a bedroom that needs real privacy, we suggest a pocket door or a swing door. For a pantry, laundry, office or closet, a barn door is fine and we install a hook-style privacy latch when you want one.
