Start by locating the exact rub point or latch miss, then check hinge screws, weatherstripping, and strike plate alignment before removing wood. Your door can scar paint, crush a seal, or loosen hardware further when you force it shut.
This repair path covers sagging, sticking, swollen wood, and latch trouble for homeowners who need smooth closure without removing material that the door still needs.
Mark Contact Points Before Touching Hardware
A narrow, even gap around the door shows that the slab sits square in the opening. Uneven clearance points to a specific fault. Open and close the door under normal hand pressure while watching the top edge, hinge side, latch side, and floor. Your goal is to find one contact point before changing a screw.
Separate rubbing from latch trouble
A door that stops before reaching the door jamb has a clearance problem. A door that reaches the jamb but springs open has a latch problem. Your repair path changes based on that difference, because hinge work, strike plate movement, and edge trimming address separate faults.
- Check the top gap for a narrow space near the latch side, which points toward a sagging door.
- Watch the floor for a lower corner that drags near the latch side during closing.
- Inspect the jamb for paint ridges, split wood, loose trim, or bowed stop molding.
- Press the latch with the door open to confirm that the latch bolt moves freely and returns fully.
- Check weatherstripping for folded foam or a bulb seal compressed tightly enough to resist closure.
Mark the evidence rather than guessing. Painter’s tape on a suspected edge shows fresh scuffs after one close. Chalk works on dark paint, while a light lipstick smear transfers a contact mark to the door frame. Your mark shows where the door rubs against frame wood rather than where you expected it to rub.
For a door won’t latch problem, darken the latch bolt with lipstick or a dry-erase marker. Close the door gently and inspect the mark inside the strike plate opening. That transfer shows whether the bolt lands high, low, or sideways.
Clear simple obstructions before altering wood
Paint buildup can narrow a gap enough to turn a smooth door into a sticking door. Scrape only the raised ridge from the door edge, door jamb, or strike plate, then retest the swing. Your door should move farther after that narrow ridge is removed.
WD-40 can loosen grime on exposed hinge knuckles, but it does not correct a door that rubs against frame wood. A rub mark near one corner points toward alignment, while a broad mark along an edge points toward swelling, finish buildup, or a distorted slab.
That marked pattern separates loose hinge screws from swollen wood and frame movement. The location matters more than the force used to close the door. Your next repair should follow the evidence left by the door.
Use the Gap Pattern to Identify the Source
A latch-side upper corner rubbing the jamb points toward hinge sag. Broad rubbing along one wood edge points toward moisture, thick paint, or a warped slab. Your marks keep you from shaving the wrong edge and leaving a permanent gap after a hardware repair.
| Visible clue | Likely source | Repair direction |
|---|---|---|
| Top latch corner rubs | Loose hinge screws or door sag | Tighten hinges and repair stripped holes |
| Latch hits above or below opening | Hinge sag or strike misalignment | Correct hinge position before moving the strike |
| Broad edge sticks during humid weather | Wood expansion and humidity | Clear paint and inspect moisture before sanding |
| Gaps change around the whole slab | Shifted frame, warped door, or racking | Inspect the jamb and contact a repair professional |
Loose hinge screws let the door weight pull the slab down and toward the latch side. That movement makes the latch bolt strike above or below the opening. Your door can also drag near the floor because the lower latch corner travels downward as the upper hinge loses grip.
Wood expansion and humidity follow moisture rather than hardware failure. An interior wood door can stick during humid weather and regain clearance in dry indoor air. Your broad rub line along one edge points away from the strike plate and toward swollen wood or swollen paint.
Do not plane a door edge because one corner rubs. A sagging hinge can leave that mark, and removed wood stays missing after the hinge receives repair.
Cracked trim, a split door jamb, soft rot, or changing gaps on all four sides point beyond a small adjustment. Frame movement can turn a square opening into a subtle parallelogram. Your door then catches because the slab no longer matches the shape of the opening.
Because hinge-side looseness shifts the entire slab, correcting it first prevents a misleading strike adjustment.
Repair Hinge Screws Before Moving the Strike Plate
A Phillips screwdriver and five minutes of careful work solve a large share of closure trouble. Close the door enough to reduce weight on the hinges, then tighten each hinge screw in the door leaf and jamb. Your retest after tightening shows whether the slab moved back into position.
Start at the top hinge. That hinge carries a large share of the door’s hanging load and has the strongest effect on latch-side sag. Your latch mark can shift after one loose upper screw gains solid grip.
Repair stripped hinge screw holes
A screw that spins without drawing tight has lost its wood grip. Remove one loose screw at a time, fill the damaged hole with glued hardwood slivers or wood filler rated for screw repair, allow the filler to harden, then drive the screw back straight. Your screw needs firm wood around its threads.
A longer jamb screw can reach framing lumber behind the jamb and restore grip. A 3-inch screw is a frequent choice, though wall construction varies. Your screw must enter solid framing rather than pull against trim or an empty space behind the jamb.
- Support the slab with a folded wedge or helper before removing a screw under load.
- Change one screw at a time so the hinge leaf stays seated in its mortise.
- Drive straight so the screw head seats flush and the hinge barrel remains aligned.
- Stop at resistance because overtightening can strip soft jamb wood or bend the hinge leaf.
Use shims only behind sound hinges
Shims sit behind a hinge leaf and move the door swing by a small amount. They work on a sound door whose hinge mortise sits too deep, but a shim can move the rub point from one edge to another. Your shim belongs behind one hinge leaf only after the screws, mortises, and jamb wood feel firm.
This is how you adjust door hinges without cutting wood too soon. Hinge repair corrects vertical sag, yet it cannot correct a strike opening placed slightly off center. Your latch mark becomes reliable only after the door swings without rubbing.
Center the Latch Bolt in the Strike Opening
A clear latch mark shows the direction for a small plate movement. Your door must swing freely before this step, because moving the strike plate cannot correct a slab that still drops on loose hinges. A plate moved around a sagging door creates a new problem after the hinge is repaired.
Shift the strike plate in small increments
Loosen the two strike screws and move the plate only enough to center the mark. A small upward, downward, or sideways shift can fix misaligned door latch trouble without enlarging the jamb cutout. Example: a bolt mark 1/16 inch below the opening calls for a similarly small downward plate movement.
Close the door five times without turning the lock. Your latch bolt should enter fully with normal hand pressure, and the door should stay shut without a shoulder push. Schlage and Kwikset latch assemblies use the same bolt-and-strike relationship, though plate shapes differ.
Keep exterior strike openings tight
File the metal opening or deepen the wood pocket only enough for full latch travel. An oversized opening weakens wood around the strike and leaves less material for the latch bolt to catch. Your exterior strike screws deserve close attention because they resist force at the jamb.
Exterior lock hardware works as a system. Keep the strike plate flat, use screws with solid wood engagement where jamb construction allows it, and avoid carving a wide opening around the latch bolt.
Hardware strength depends on the wood holding it. Rotten jamb wood, loose trim, and cracked framing weaken even a well-positioned plate. ANSI/BHMA publishes performance standards for residential door hardware, which aligns with the need for secure screw engagement and sound jamb material.
Hardware alignment will not solve seasonal wood expansion, which calls for a different and more restrained correction.
Address Swelling and Edge Binding With Restraint
A broad lipstick transfer along the latch edge points to swollen wood or heavy finish after the hinge and strike checks. Start by clearing paint ridges and lifting folded weatherstripping away from the contact path. Your door needs workable clearance without becoming loose or drafty.
Wait through a moisture-driven bind that remains safe
Seasonal humidity makes wood take on moisture and expand across its width. A door that closes and latches with light pressure can remain untouched while indoor moisture and nearby leaks receive attention. Your bathroom exhaust, damp basement, or unsealed exterior edge can keep wood swollen for longer than expected.
A bind that stays in the same marked spot through drier conditions calls for limited material removal. Remove the door, mark the contact area again, and sand only that small zone. Your aim is a thin correction followed by another fit check, not broad reshaping of the edge.
Plane only a persistent, verified rub line
A wood plane removes material faster than sandpaper and needs more control. Use a plane only after hinge position, frame condition, paint, weatherstripping, and moisture sources have been checked. Your plane should travel in shallow passes with its sole flat against the edge.
- Mark the edge with tape or chalk so removal stays on the verified contact area.
- Remove tiny amounts and hang the door again after each short sanding or planing pass.
- Seal bare wood with primer and paint, especially on exterior door edges exposed to moisture.
- Check nearby seals around glass, bottom rails, and exterior trim for water paths feeding swelling.
Freshly exposed wood absorbs moisture faster than painted wood. Your resealed edge reduces repeat swelling at the trimmed area. That step matters after sanding and after plane work.
Verify the Repair and Recognize Structural Limits
Normal hand pressure is the final measure of a successful repair. Close the door from both sides at least five times, engage the lock where present, and watch for a new scrape at the floor or weatherstripping. Your repaired door should latch without lifting the knob, pulling the slab, or pushing near the lock.
Check clearance after each repair
Look for a workable gap at the top, sides, and floor. A credit card is not a universal clearance gauge because exterior weatherstripping and interior doors use different gaps. Your clearance should look even and allow smooth movement without scraping.
Example: a bedroom door that swings smoothly after the top hinge receives repair but still clicks against the strike needs a plate movement rather than more sanding. That repair order helps you fix a door that won’t close properly without masking the actual source.
Stop work before structural damage grows
A visibly warped slab, rotten door edge, cracked jamb, loose hinge area, or major frame racking calls for a carpenter or qualified door repair professional. Your home could have settlement movement or water damage that hinge and strike work cannot correct.
Fire-rated doors need extra restraint. Altering the slab, hinges, door latch, closer, frame, or seals can affect fire performance. Your exterior door also needs careful work around weather resistance and security, especially near a changed strike opening.
Closing Checks
The cleanest repair starts with evidence rather than a wood plane. Mark the contact point, tighten and repair hinge screws, clear paint or weatherstripping, then center the strike plate before trimming an edge. Your restraint protects door fit, jamb strength, and latch security.
Start with the repair that leaves the least permanent change. A screw repair or strike adjustment can restore closure without removing wood. Your final test should feel smooth from either side of the door.
FAQ
Why won’t my door close properly even though the hinges look fine?
Hinges can look sound while hinge screws have lost grip inside the door jamb. Check each screw for spinning, looseness, or a hinge leaf pulled away from its mortise. Your door can sag enough to miss the strike plate even without visible hinge damage.
How do I tell whether a door is sagging, rubbing, swollen, or out of alignment?
Use tape, chalk, or lipstick to mark the contact area. A top latch-side corner rub points toward sag, while a broad edge mark points toward wood expansion and humidity. Your latch bolt mark shows alignment trouble inside the strike opening.
Can tightening hinge screws fix a door that will not latch?
A few tightened hinge screws can raise a sagging door enough to bring the latch bolt back toward the strike plate opening. Start with the top hinge, then retest the latch. Your strike plate should stay in place until the door swings freely.
How do I adjust a strike plate so the latch catches correctly?
Darken the latch bolt, close the door gently, and inspect the transfer mark. Loosen the strike screws and move the plate only enough to center that mark. Your plate movement should match the bolt miss, such as 1/16 inch downward for a low bolt mark.
What should I do if a wood door sticks because of humidity?
Clear paint ridges, inspect weatherstripping, and look for moisture sources near the door. Your door can regain clearance as indoor air dries, especially where the rub line covers a broad section of the edge. Sand only a persistent rub line that remains after drier conditions return.
At what point should I plane or sand a door edge?
Sand or plane after hinge screws, jamb condition, paint buildup, weatherstripping, and strike alignment have been checked. Your marked contact area should remain in the same spot through repeated closes. Remove a very small amount, then seal the exposed wood.
