Why is my door jammed, and what can I do?
A door usually jams because the door or frame has moved, the hinges have dropped, the floor has risen, or the latch or lock has failed. Check which it is first; if a locked or outside door will not open, call a locksmith rather than forcing it.
Last reviewed:Why do doors jam?
A door has to fit its frame with a small, even gap all round. Anything that changes the shape of the door, the frame or the floor can close that gap and make it rub or stick. A door that will not open at all is a different problem, usually the latch or lock.
The main causes are:
- Hinges. Screws work loose over time and the door drops on the handle side, so the top corner catches the frame.
- Swelling. Timber doors and frames take up moisture and swell slightly, especially on outside doors and in bathrooms.
- Paint. Layers of paint on the edges and the frame build up until there is no gap left.
- A raised floor. New carpet, underlay or a wooden floor can lift the floor level enough for the door to scrape.
- Movement. A frame that has shifted, a sagging lintel above, or new cracks round the door can all make it bind.
- The latch or lock. A worn latch, a broken spring or a failed lock can stop a door opening even when it fits well.

How can you tell which problem you have?
Look at the gaps. Close the door gently and look at the gap round the edges. A gap that is wide at the bottom and tight at the top on the handle side points to dropped hinges.
Look for rub marks. Shiny or scuffed patches on the door edge or frame show where it catches.
Check the hinges. Open the door and lift the handle end gently. If it moves up and down at the hinges, the screws are loose.
Check the floor. If the door scrapes along the bottom, and the floor covering is new, the floor has risen.
Try the handle with the door open. If the latch does not move in and out freely with the door open, the latch or handle is the problem, not the fit.
Look round the frame. New diagonal cracks in the plaster above a door, or a door that has started sticking along with others nearby, can mean the building is moving. That needs a builder to look, not just a door repair.
What can you safely try yourself?
Tighten the hinge screws. If a screw spins in its hole, a longer screw of the same gauge often grips again.
Clean and lubricate the latch. A little lubricant on the latch and the strike plate can free a stiff latch.
Wait for dry weather. A door that swells in damp months may ease by itself. Planing a swollen door in winter can leave a big gap in summer.
Leave locks alone if you are not sure. A lock you take apart can be harder and dearer to fix than one a locksmith opens and replaces.
If a door needs to come off its hinges, trimming at the bottom or rehanging, how to hang a door explains the stages. Heavy outside doors, glazed doors and fire doors are jobs for a professional.
When should you call someone?
- Locked out, or locked in. Call a locksmith. Our locksmiths page covers the trade, and the locksmith cost guide explains what changes the price.
- uPVC or composite doors. A failed multipoint lock or gearbox needs the right part. Locksmiths and glaziers who fit doors can both help.
- Timber doors that rub or stick. Joiners and carpenters ease, rehang and refit doors. Some handymen take on simple internal doors.
- A frame that has moved. Door frame replacement covers that job, and a builder should look at any cracks first.
If you replace a front door, the Planning Portal says that in a home built since 1999 the threshold must stay level, or the work will not comply with the building regulations [S2]. Ask the installer how the new door will keep level access.
Why does a jammed door matter for safety?
A door you use to get out in an emergency needs to open quickly. The government's Fire Kills campaign advises identifying escape routes, keeping exits clear, and keeping door and window keys in a safe but accessible place near the exit they fit [S1]. It also says not to leave keys in locks where they could fall out or be hard to find in the dark [S1].
If your front or back door is stiff, or a lock is failing, do not leave it until it jams completely. Citizens Advice suggests getting written quotes from at least 3 different traders before you decide on one [S3], but for a lock you cannot open, one call to a locksmith is the sensible first step.

Questions about jammed doors
My uPVC front door is jammed shut. Can I force it?
Please don't. A uPVC door usually has a multipoint lock with hooks or rollers along the edge, worked by a gearbox inside the door. Forcing the handle or prising the edge can break the gearbox and damage the frame, which makes the repair bigger. A locksmith can usually open it and replace the failed part.
Why does my door stick only in winter?
Timber takes up moisture from the air and swells slightly, then shrinks again when the air is drier. A door that rubs in damp months and works in summer is usually a seasonal fit problem. Check the hinges first, then ask a joiner whether it needs easing and sealing.
Can a jammed door be a fire risk?
It can if it is on your way out. The government's Fire Kills campaign says to plan escape routes, keep exits clear and keep door keys in a safe but accessible place near the exit they fit. A door you cannot open quickly is worth fixing promptly.
