A door that won’t close properly is one of those small irritations that slowly drives you mad — the bedroom door that needs a hip-check, the bathroom door that won’t latch, the front door that sticks every damp October. When people ask how do I fix a door that will not close properly, the good news is that 90% of door problems are simple hinge or alignment issues, fixable in under an hour with basic tools.
I’ve fixed sticking doors in Victorian houses (where every frame has shifted in 130 years) and new-builds alike. The trick is diagnosing correctly before you start planing — because planing the wrong edge makes everything worse. Here’s the diagnostic method.
How do I fix a door that will not close properly? Diagnose first
Close the door slowly and watch where it binds — the shiny rub marks on the edge or frame tell you exactly where the problem is. The three classic faults: sticking on the leading edge or top (door or frame has swollen/shifted), not latching (the latch bolt misses the strike plate), and sagging (the door drops on its hinges, rubbing at the top on the handle side). A fourth common one: the door closes but springs open, which means the hinges are binding or the frame is twisted.
The pencil test pinpoints sticking: close the door on a piece of paper at various points — where the paper grips tight, that’s your bind. Check the hinges too: open the door and lift the handle side — if there’s vertical play, the hinge screws are loose or the screw holes are stripped. Seasonal sticking (fine in summer, stuck in winter) is moisture swelling, common with wooden doors and frames; a door that suddenly won’t latch after years of working often means the house has settled slightly or a hinge screw has worked loose.
- Watch where it binds — rub marks show the spot
- Pencil-and-paper test to pinpoint sticking points
- Lift the handle side to check for hinge play
- Seasonal sticking = moisture; sudden latch failure = settlement or loose screws
- Never plane until you’ve tried hinge fixes first
The fixes, easiest first
Start with the hinges — they solve most problems. Tighten every hinge screw; if a screw spins without gripping, the hole is stripped — remove the screw, push in a matchstick or dowel coated in wood glue, let it set, and re-drive the screw. For a sagging door, the top hinge takes the load: replace one short screw in the top hinge with a 75mm screw driven into the framing behind the architrave, which pulls the door back up. This single trick fixes an astonishing number of ‘broken’ doors.
If the latch misses the strike plate, the fix is usually moving the plate, not the door. Mark where the latch actually hits, chisel the mortise slightly in the right direction (a sharp 25mm chisel, small cuts), and refit. For sticking edges, once hinges are ruled out: mark the bind, remove the door (knock the hinge pins up from below), and plane the marked area with a sharp block plane — taking thin shavings, a fraction of a millimetre at a time. Seal the planed edge with paint or varnish immediately, or moisture will swell it again. Rehang and test before doing more — you can always take more off, you can’t put it back.
When it’s the frame, not the door
Sometimes the door is innocent and the frame is guilty — common in old houses where frames have twisted over decades. Signs: the gap around the door is visibly uneven (wide at top, tight at bottom, or vice versa), or the door rocks in the frame. Minor frame issues can be shimmed: remove the architrave on the problem side, pack thin shims behind the frame to straighten it, and refix. It’s fiddly but very doable.
Know when to stop: a door that’s been planed multiple times over the years may be too thin at the edges to plane again; a badly twisted frame in a Victorian house might need a joiner; and fire doors (with their intumescent strips and certification) should never be planed by amateurs — altering a fire door can void its rating. For standard internal doors, though, the hinge-and-plane method above resolves the vast majority. And if the door is a cheap hollow-core that’s had it, a new pre-hung door is £80–£150 — sometimes replacement beats repair.
Draught-proofing doors and ongoing maintenance
A door that closes properly is only half the battle — a door that seals properly is the goal. Once the door shuts cleanly, draught-proof it: self-adhesive foam or brush strips around the frame (£10, 20 minutes), a brush strip on the bottom, and check the latch holds the door tight against the seals. Internal doors leak surprising amounts of heat between rooms; sealing the worst offenders (the living room door, the bathroom door) makes a noticeable comfort difference. Don’t seal bedroom doors completely — rooms need some airflow to avoid condensation.
Ongoing maintenance keeps doors working: tighten hinge screws annually (they loosen with use — the five-minute job that prevents the sag), wax or lubricate sticky locks with graphite powder (never oil — it gums up), and touch up paint on planed edges before winter (bare wood swells). For external doors, check the weather seals each autumn and the threshold drainage — blocked threshold drains cause the mysterious puddle inside the door. Doors are mechanical things; a little annual attention keeps them closing first time for decades.

- Tighten hinge screws annually — prevents sag
- Graphite powder for locks, never oil
- Touch up planed edges before winter
- Check external door seals and threshold drainage each autumn
Doors that close first time
Diagnose with the paper test, fix hinges before planing, move the strike plate for latch issues, plane thin shavings only, and seal any bare wood. Most sticking doors are a 30-minute hinge job, not a door problem at all.
For patching up the frame afterwards, repair a hole in a plaster wall covers plaster repair, and paint a ceiling without getting streaks helps with a streak-free ceiling repaint if the room needs refreshing. For tool reviews, Which? home improvement guides is the independent source.
The door-maintenance mindset: doors are the most-used moving parts in the house, and they repay tiny amounts of attention hugely. A door that closes, latches and seals properly is a small daily pleasure — and the fix is almost always simpler than the annoyance suggests.
