Slams shut fast
You crack the door open and it takes off hard, often banging the frame or latch side trim.
Start here: Check whether the top hinge screws are loose or the top hinge leaf is pulling away from the jamb.

Door Slams Shut
Direct answer: A door that slams shut usually means the door is no longer hanging plumb. Most often that comes from loose hinge screws, a sagging top hinge area, or worn door hinges that let the slab lean and swing on its own.
Most likely: Start with the top hinge. If the screws are loose, stripped, or pulling out of the jamb, the door will drift or slam shut even when the latch and handle seem fine.
When a door used to stay put and now takes off on its own, gravity is telling you the door slab has shifted. Reality check: even a small hinge sag can make a door feel much worse than it looks. The good news is you can usually spot the problem with a screwdriver and a careful look at the hinge side before you buy anything.
Don’t start with: Do not start by planing the door, bending the latch, or buying a new handle set. Those are common wrong moves when the real problem is hinge alignment.

What a door that slams shut usually looks like
Drifts shut slowly
The door does not slam, but it will not stay half open and always creeps closed.
Start here: Look at the reveal around the door, especially the gap at the top and latch side, for signs the slab is hanging out of plumb.
Started after the door got loose or wobbly
The handle side feels lower than it used to, or the latch side rubs before the door closes.
Start here: Inspect all hinge screws and the hinge knuckles for wear before blaming the latch.
Only one door in the house does it
Other doors behave normally, but this one swings shut every time.
Start here: Focus on that door's hinges and jamb condition first, not house settling as your first assumption.
Most likely causes
1. Loose top door hinge screws
The top hinge carries a lot of the door's weight. When those screws loosen, the slab leans and gravity pulls it shut.
Quick check: Open the door partway and look for a widened gap at the top latch side or a hinge leaf that shifts when you lift the handle side slightly.
2. Worn door hinges
If the hinge pin area or knuckles are worn, the door can sag even when the screws are tight.
Quick check: Grab the latch side and lift gently. If you feel play at the hinges or see the slab move up and down, hinge wear is likely.
3. Stripped screw holes in the door jamb
Sometimes the screws feel snug at first but never really clamp because the wood behind them is chewed out.
Quick check: Remove one suspect hinge screw. If it comes out dusty, short, or with no bite marks, the jamb hole may be stripped.
4. Frame or jamb out of plumb
A door can swing shut on its own when the opening has shifted, even if the hinges are still attached.
Quick check: Hold a level on the hinge-side jamb. If it is noticeably out of plumb and the hinges are tight, the opening has moved.
Step-by-step fix
Step 1: Confirm it is a hanging problem, not a latch problem
A door that slams shut because it is out of plumb needs hinge or jamb work. A sticky latch is a different problem and sends you the wrong direction.
- Open the door halfway and let go carefully while standing clear of the swing path.
- Watch whether the door moves freely on its own before the latch gets near the strike.
- Close it slowly and look at the gap around the slab. Compare the top gap on the hinge side and latch side.
- If the latch or deadbolt is the only thing hanging up, this is more of a sticking or alignment issue than a self-closing issue.
Next move: If the door clearly swings on its own before the latch reaches the frame, stay on the hinge-and-plumb path below. If the door only acts up when the latch meets the strike, the problem is likely latch alignment or binding instead.
What to conclude: A free-swinging door that will not stay put is usually hanging crooked, not suffering from a bad handle set.
Stop if:
- The door is heavy enough to be unsafe to control alone.
- The slab is cracked, split at a hinge, or partly detached from the jamb.
Step 2: Tighten every hinge screw, starting at the top hinge
Loose screws are the fastest, safest, most common fix. Start here before removing hardware or altering the door.
- Support the door so it does not drop while you work.
- Use a screwdriver to snug every screw on the top, middle, and bottom door hinges.
- Pay close attention to screws that spin without tightening or sit proud of the hinge leaf.
- After tightening, open the door halfway again and see whether it still drifts or slams shut.
- If one or two screws were obviously loose and the door now stays put better, you likely found the main issue.
Next move: If the door now holds position or moves much less aggressively, keep using it and recheck those screws over the next few days. If screws will not tighten or the door still drops at the latch side, move on to checking for stripped holes or worn hinges.
What to conclude: A change after tightening points to hinge attachment. No change means the wood behind the screws or the hinges themselves need closer attention.
Step 3: Check for sag, play, and stripped hinge-side wood
This separates a simple loose-screw fix from a worn-hinge or damaged-jamb repair. It also tells you whether replacement parts are justified.
- With the door open a few inches, lift gently on the latch side and watch the hinges.
- Look for up-and-down movement at the hinge knuckles or a gap opening behind the top hinge leaf.
- Remove one suspect screw from the top hinge jamb leaf and inspect it for length and clean wood bite.
- If the screw hole is stripped, repair the hole so the screw can bite solid wood again, then retighten the hinge.
- If the screws hold well but the hinge still has visible play, the hinge itself is worn.
Next move: If repairing the stripped hole and retightening the hinge stops the self-closing, you can usually stop there. If the screw holes are solid but the hinge still has slop, plan on replacing the worn door hinge with a matching size and finish.
Step 4: Check whether the hinge-side jamb is out of plumb
If the hinges are sound but the opening has shifted, replacing hardware alone will not stop the door from swinging shut.
- Place a level on the hinge-side jamb from near the top hinge down toward the bottom hinge.
- Check the reveal again with the door nearly closed. A tight top gap on one side and a wide gap on the other usually confirms the slab is hanging off line.
- Look for trim cracks, separated caulk lines, or a jamb leg that has moved away from the wall.
- If the jamb is only slightly out and the hinge area was loose, correcting the hinge attachment may be enough.
- If the jamb is clearly out of plumb with solid hinges, the repair moves into jamb adjustment or reframing work.
Next move: If the jamb is close to plumb and the door improved after hinge work, finish by fine-tuning the hinge attachment and verifying swing control. If the jamb is clearly out of plumb, stop short of forcing the door into place with random shims or longer screws everywhere.
Step 5: Make the repair that matches what you found
Once you know whether the problem is loose screws, stripped wood, worn hinges, or a moved jamb, the fix gets much more straightforward.
- If loose screws were the issue, retighten them, replace any damaged hinge screws with matching door hinge screws that bite solid wood, and test the swing again.
- If the top hinge or other hinges have visible play, replace the worn door hinge one at a time so the door stays aligned.
- If the jamb screw holes were stripped, repair the wood so the screws hold firmly, then reinstall and tighten the hinge.
- If the jamb is out of plumb or the frame has shifted, plan for jamb adjustment or a carpenter's repair instead of forcing the slab to behave.
- After the repair, open the door to several positions and confirm it no longer takes off on its own.
A good result: If the door stays where you leave it and closes without dropping or rubbing, the repair is done.
If not: If the door still swings shut after solid hinge repair and the jamb reads out of plumb, the next move is frame correction by a pro.
What to conclude: The door should behave normally once the hinge side is secure and plumb enough. If it does not, the opening itself is the problem.

FAQ
Why does my door suddenly slam shut when it used to stay open?
Most of the time the top hinge area has loosened up or the door has started to sag. It does not take much movement for gravity to take over and pull the slab shut.
Can a bad latch make a door slam shut?
Usually no. A bad latch can make closing rough or noisy, but a door that moves on its own before it reaches the frame is usually hanging out of plumb or has hinge trouble.
Should I plane the door if it swings shut by itself?
Not as a first move. Planing removes material but does not correct a loose hinge, worn hinge, or shifted jamb. Fix the hanging problem first.
Do I need to replace all the door hinges or just one?
Start with the hinge that shows the problem, usually the top door hinge. If the others are tight and not worn, you may only need one hinge or a few new hinge screws.
When should I call a pro for a door that slams shut?
Call for help if the jamb is badly out of plumb, the hinge-side wood is split or rotten, the frame has moved, or the door is too heavy to handle safely by yourself.
