How to Fix a Door That Won't Close: 6 Causes and Fixes (2026)

Frequently Asked Questions

Why won't my door close all the way?

The most common causes are loose hinges (easy fix: replace hinge screws with longer 3-inch screws), a shifted or misaligned strike plate (chisel the mortise wider or move the plate), seasonal wood swelling from humidity (plane or sand the latch-side edge), a warped door (heat and clamp, or plane), or foundation settling (requires carpentry adjustment to the frame). Check hinges first — they cause the majority of door problems.

How do I know if my door is stuck because of the hinge or the frame?

Look at where the door is sticking. If it sticks at the top corner on the latch side, the problem is usually the top hinge is loose. If it sticks along the latch edge or the bottom, the issue is swelling, frame settling, or strike plate misalignment. Rub chalk or lipstick on the door edge and close it partway — the chalk transfers to the frame wherever they're touching and shows you exactly where to work.

How do I fix a door that won't latch?

Look at the latch bolt and strike plate. If the latch bolt is hitting above or below the strike plate hole, the plate has shifted — loosen the screws and move it to realign with the latch. If the latch barely misses, a simple fix is to file the strike plate hole wider with a metal file. If the gap is large (more than 1/8 inch), remove the plate, chisel the mortise to the new position, and re-install.

Can humidity cause a door to not close?

Yes — this is very common. Wood expands in summer humidity and contracts in winter. A door that's fine in winter may stick badly in July. The permanent fix is to seal all six sides of the door (including the top and bottom edges) with primer and paint — unsealed wood absorbs moisture and swells. A door that only sticks seasonally needs paint more than planing.

How do I fix a door that rubs at the top?

Rubbing at the top corner (latch side) almost always means the top hinge has loose screws, causing the door to sag. Replace the top hinge screws with 3-inch screws that reach the stud behind the doorframe. If the hinge leaf itself is stripped or bent, replace the hinge. If new long screws don't fix the sag, check if the frame header has shifted — that's a structural issue requiring shimming or carpentry.

How do I fix a warped door that won't close?

Minor warps (under 1/4 inch): adjust the strike plate to match the new position of the latch, and add a third hinge in the middle of the door to pull the bow straight. Significant warps: lay the door flat on sawhorses in the sun (concave side up) with weights on the center for 24-48 hours to slowly reverse the warp. If the warp is severe or permanent, the door needs to be replaced.

Most doors that won’t close have one of three problems: loose hinge screws (fix with longer screws, 2 minutes), swollen wood from humidity (plane or sand the sticking edge), or a misaligned strike plate (adjust with a chisel or move the plate).

A door that won’t close is almost always one of a short list of fixable problems — and 90% of them don’t require replacing anything. The key is diagnosing which problem you have before reaching for a plane or calling a carpenter.

Here’s how to read the symptoms and fix the right thing.

Step 1: Diagnose where it’s sticking

Before touching any tools, close the door slowly and watch where it catches. The location tells you the cause:

Where it sticks	Most likely cause
Top corner, latch side	Top hinge loose or hinge pin worn
Middle of latch edge	Swollen wood or out-of-plumb frame
Bottom of latch edge	Foundation settling or threshold issue
Doesn’t latch, but doesn’t stick	Strike plate shifted
Bows in the middle	Warped door
All around the frame	Frame racked (foundation movement)

The chalk test: Rub chalk, lipstick, or a lumber crayon on the door’s edge and close it part-way. Wherever the chalk transfers to the frame is exactly where the door is binding.

Fix 1: Loose hinge screws (most common)

Symptoms: Door sags; scrapes at the top-latch corner; hinges look slightly open when the door is shut.

Why it happens: The short screws that come with most door hinges (typically 3/4 inch) only grab the door casing, not the structural stud behind it. Over time, they strip and the hinge pulls away from the frame.

Fix:

1. Open the door and have someone hold it steady (or wedge it with a doorstop).
2. Remove the hinge screws one at a time from the door frame side (not the door side).
3. Replace them with 3-inch #10 wood screws — these reach through the casing and into the stud.
4. If the holes are stripped (screw spins without tightening), use a wooden toothpick and wood glue: dip a toothpick in glue, snap it off in the hole, let dry for an hour, then drive the new screw. The wood plug gives the screw something to grip.

This fix takes 10–15 minutes and solves the majority of door-won’t-close problems.

Fix 2: Misaligned strike plate (door doesn’t latch)

Symptoms: The door closes but the latch bolt doesn’t catch, or catches but releases when you push on the door.

Diagnosis: Watch the latch bolt as you close the door. If it’s hitting above, below, or to the side of the hole in the strike plate, the plate has shifted or the door has settled.

Fix — minor misalignment (under 1/8 inch):

File the strike plate opening wider with a metal hand file. Work slowly and test frequently — you only need to remove a little material.

Fix — significant misalignment:

1. Unscrew the strike plate.
2. Mark the new position (where the latch actually hits the frame) with a pencil.
3. Use a sharp chisel to extend the mortise (the recessed pocket) to the new position.
4. Fill the old screw holes with toothpicks and glue, then reinstall the plate in the new location.

If the gap between where the plate is and where it needs to be is more than 1/4 inch, consider a heavy-duty strike plate with longer screws — these use 3-inch screws into the stud and provide a larger hole for the latch bolt.

Fix 3: Swollen wood (seasonal sticking)

Symptoms: Door closes fine in winter or spring, sticks in summer. Sticking is along the latch edge or top edge, not at hinge corners.

Fix — temporary: Rub a candle or bar of soap along the sticking edge as a dry lubricant. This buys time but doesn’t fix the underlying issue.

Fix — permanent (sealing):

If all six sides of the door aren’t painted or sealed (including the top and bottom edges), moisture enters through those bare surfaces and swells the wood. Remove the door, seal all edges with exterior primer and paint, and the seasonal swelling should stop.

Fix — planing:

If the door still sticks after sealing, or if the swelling is too severe, you’ll need to plane the edge:

1. Remove the door (tap out hinge pins from bottom to top with a nail and hammer).
2. Use a hand plane or belt sander to remove material from the sticking edge.
3. Work in thin passes (1/32 inch at a time) and re-hang to test fit frequently.
4. Seal the planed edge with primer before re-hanging — bare wood will reabsorb moisture immediately.

How much to remove: Remove only enough to create 1/8-inch clearance when the door is at its most swollen (summer). If you remove too much, the door will rattle in winter.

Fix 4: Warped door

Symptoms: Door bows in the middle; gaps at top or bottom when closed; lock or deadbolt difficult to engage.

Minor warp (under 1/4 inch):

Add a third hinge at the center of the door. This distributes the load and pulls the bow straight in many cases. Also check that the existing hinges aren’t pulling the door out of the frame.

Moderate warp (1/4 to 1/2 inch):

Lay the door flat on two sawhorses with the concave (hollowed) side facing up. Place heavy weights or clamps in the center of the bow, with padding to protect the door surface. Leave in direct sunlight for 24–48 hours — heat + pressure slowly reverses the warp. Works best on solid-core doors.

Severe warp: Replace the door. Warped hollow-core doors especially are not worth the effort to repair.

Fix 5: Frame out of square (settling or racking)

Symptoms: Large, uneven gap around the door; multiple areas of binding; door binds differently depending on which hinge carries the weight; new problem in an older house after storms or foundation work.

Diagnosis: Use a long level on the hinge-side jamb. If it’s significantly out of plumb (more than 1/4 inch in 4 feet), the frame has racked.

Fix:

1. Check the hinge-side jamb. If it’s leaning, you can often shim behind it to push it back toward plumb.
2. Remove the casing molding on the hinge side.
3. Use composite door shims behind the jamb at hinge locations to adjust.
4. Re-drive the hinge screws with 3-inch screws through the jamb, shims, and into the stud.

If the frame is racked due to foundation settling (sagging floor joists, post problems), the shim fix is temporary — the underlying structural issue needs to be addressed. A structural contractor evaluation is warranted if multiple doors and windows in the home are sticking simultaneously.

Fix 6: Worn or bent hinges

Symptoms: Door binds at the hinge side; hinge barrel is visibly loose or bent; door feels floppy on its hinges.

Fix:

Replace the hinges. Standard residential hinges are 3.5 × 3.5 inch or 4 × 4 inch. Match the size and finish of the existing hinges. If the mortises are already cut correctly, the swap takes about 20 minutes per hinge.
