Common Pocket Door Problems and How to Fix Them

A well-fitted pocket door should glide open and closed with very little effort. When it doesn’t, the fix is usually simpler than people expect. Most pocket door problems come down to a handful of causes: the door’s height, the floor guide, something sticking into the pocket, or a track that isn’t level.

This guide covers the most common pocket door problems, what causes them and how to put them right, starting with the easiest checks first.

Before you start: diagnose first, adjust second

A pocket door is a system. The door hangs from runners (also called hangers or trolleys) in a track at the top of the frame, a guide at the floor keeps it centred, and stops limit how far it travels. A symptom in one place can start somewhere else, so work methodically:

1. Slide the door slowly and note exactly where any noise, drag or tilt begins.
2. Check what you can see: the floor guide, the stops, the handles, and the gap at the top and bottom of the door.
3. Make one small change at a time, then test the full travel again.

Avoid planing or cutting the door until you’ve ruled out adjustment. Trimming a door is permanent, and it often doesn’t fix the real cause.

You’ll usually need a spanner or Allen key for the hangers (check your kit’s instructions for the right size), a screwdriver, a spirit level and a torch.

Problem 1: The door scrapes the floor

Likely causes: the door has been set too low, a new floor finish has raised the floor level, or one hanger has loosened.

How to fix it: Most pocket door kits let you raise or lower each end of the door at the hangers. Adjust one end at a time, in small steps, until the door clears the floor evenly, then re-tighten any locking nut or grub screw. Every kit is different, so follow your manufacturer’s instructions. On some systems, such as Eclisse’s Syntesis flush frames, you remove a cap on the door edge to reach the adjustment.

If you’ve laid a thicker floor since the door was fitted, check the clearance the kit requires before you adjust. Some systems have a limited adjustment range.

Problem 2: The door is crooked, or the gap at the jamb is uneven

Likely causes: the two hangers are at different heights, a hanger plate is loose, or the track or jamb isn’t level and plumb.

How to fix it: Close the door and compare its leading edge with the jamb. If the gap tapers, raise or lower one end of the door until the edge runs parallel. If the door still won’t sit straight, put a level on the track (or the head of the frame if you can reach it) and check the jambs are plumb. The hanger adjustment levels the door; it can’t correct a twisted frame.

Problem 3: The door rubs or scrapes inside the pocket

This is one of the most common pocket door problems, and it needs attention before you keep using the door.

Likely causes:

• A screw or nail sticking into the pocket. If the plasterboard over the pocket was fixed with screws that are too long, they can poke through into the cavity and scratch the door. Kit instructions often specify the screw length to use when boarding the pocket. Henderson’s pocket door kit instructions, for example, show a maximum fixing length of 25mm for attaching the plasterboard.
• A bowed or damaged pocket. Something heavy fixed to the wall, or impact damage, can push the pocket inwards.
• A warped door. Doors that haven’t been sealed on all edges can absorb moisture and bow.
• Debris such as plaster, dust or offcuts left in the pocket.

How to fix it: Shine a torch into the pocket and look for screw tips or anything protruding. If the rubbing always happens at the same point, measure how far into the pocket it is and mark that spot on the wall, so you know where to investigate.

Protruding screws normally need to be removed and replaced with shorter ones, which may mean making good the plaster. If the pocket itself has been pushed in, the wall may need opening up to repair it. Many modern frames, including Eclisse’s, have an extractable track that lets you take the door out for repairs without breaking into the wall.

Never fix shelves, pictures or cabinets through the pocket section of the wall. Our pocket door installation guide explains how to plan around the pocket.

Problem 4: The door rolls open or closed by itself

Likely cause: the track isn’t level. A door that drifts is almost always a sign the frame was installed slightly out of level, or the building has moved.

How to fix it: Check the track with a spirit level. Tightening the floor guide to add friction might seem like a quick fix, but it just causes drag and wear. If the track is out of level, the frame needs correcting, which may mean adjusting how it’s fixed into the studwork. For a frame that’s already plastered in, this is often a job for the original installer or a carpenter.

Problem 5: The door is stiff or hard to slide all the way

Likely causes: a floor guide that’s too tight, dirt in the track, worn runners, or a door that’s heavier than the kit is rated for.

How to fix it:

• Check the floor guide. It should stop the door swinging sideways without pinching it. If it’s too tight, loosen and re-centre it.
• Clean the track. Vacuum out dust and debris. Don’t oil or grease the track unless your kit’s instructions say so, as it can attract dirt. Most modern runners use sealed bearings.
• Check the door weight. Every kit has a maximum door weight. The Rocket 90mm pocket door kit, for example, is rated for doors up to 60kg. A heavy solid or glazed door on an underrated kit will feel stiff and wear out the runners.

Problem 6: The door rattles or swings at the bottom

Likely causes: the floor guide is loose, worn, missing or set too wide.

How to fix it: Re-fix or replace the floor guide and centre it so the door runs straight without touching the sides. Also check that handles, stops and hanger fixings are tight.

Problem 7: The door won’t close fully, or bounces back

Likely causes: a stop in the track is in the wrong place, a soft close mechanism isn’t engaging, or the door is catching on something.

How to fix it: Most kits have adjustable stops inside the track. Eclisse, for example, uses adjustable stops to set how far the door projects from the pocket when open and to hold it closed. If you have a soft close, check that the activator on the door lines up with the mechanism and that the door is within the closer’s weight range. Our soft close pocket doors guide covers setting up soft closers in more detail.

Problem 8: The lock or latch doesn’t catch

Likely causes: the door has dropped or isn’t plumb, or the strike plate is in the wrong place.

How to fix it: Level the door first, using the steps above. Only move the strike once the door is hanging correctly. Otherwise, you’ll have to move it again. If you’re replacing a lock, our guide to pocket door handles explains the options.

Problem 9: The door has come off the track

Likely causes: a hanger has come loose, a runner is damaged, or a stop is missing.

How to fix it: Stop using the door and support it so it can’t fall. Then check whether the runners have simply come out of the hanger brackets or whether a part is damaged. Reattach or replace parts as your kit’s instructions describe. Don’t force a door back onto bent or broken hardware.

How to prevent pocket door problems

Most of these issues can be avoided at the fitting stage:

• Install the frame level and plumb, at finished floor level.
• Use the right screw length for the pocket, as specified by the kit manufacturer.
• Seal the door on all faces and edges, including the top and bottom, before hanging. Many door manufacturers make this a condition of their warranty, and it helps stop the door absorbing moisture and warping.
• Choose a kit rated for your door’s weight and thickness.
• Keep the pocket wall free of fixings.

Frequently asked questions

Why does my pocket door keep sticking?

The most common causes are a floor guide that’s too tight, dirt in the track, a door set too low, or a screw sticking into the pocket. Work through these checks in order before trimming the door.

Can you fix a pocket door without opening the wall?

Often, yes. Height adjustment, floor guides and stops can usually be reached with the door in place. Many modern frames also have a removable track so the door can be taken out without damaging the wall. Problems with the pocket itself may need the wall opening up.

Should I oil a pocket door track?

Usually not. Oil and grease can attract dust. Clean the track instead and only lubricate it if the kit manufacturer recommends it.

Why does my pocket door slide open on its own?

This usually means the track isn’t level. The proper fix is to correct the frame rather than tightening the floor guide.

How do I stop my pocket door scraping the floor?

Raise the door using the height adjustment on the hangers, adjusting each end a little at a time until the door clears the floor evenly. Then tighten any locking screws.
