How to Fix a Door That Won't Stay Open or Shut (4 Causes)

TL;DR: A door that won't stay where you put it is almost always caused by loose hinge screws, a door frame that's shifted out of plumb, worn hinge pins, or latch misalignment. Tighten screws first, shim hinges if the frame has settled, replace pins if the door sags, and file or adjust the strike plate if the latch won't catch. Most fixes take 15–30 minutes and require only a screwdriver, shims, and possibly a hinge-pin kit.

A door that swings shut when you want it open—or refuses to latch when you close it—is one of the most common and most annoying maintenance issues in a rental or owner-occupied home. The good news: the root cause is usually mechanical, visible, and fixable without replacing the door itself.

Okoniq Property Hub logs every repair you make, timestamps hinge adjustments and hardware swaps, and keeps photos of before-and-after alignment so you can prove the work was done if a tenant or buyer asks.

Why does a door swing closed on its own?

Gravity pulls a door toward the side where the frame is lower or the hinges are loose. If the door frame has settled—common in older homes and anything built on a slab—the top of the frame tilts forward or backward, and the door follows. Loose hinge screws let the door sag, which shifts the center of gravity and causes the door to drift.

Fix 1: Tighten every hinge screw. Use a 3-inch screw (not the short ones that came with the hinges) on at least one hole per hinge to bite into the wall stud, not just the door jamb. If a screw hole is stripped, fill it with toothpicks and wood glue, let it cure 30 minutes, then redrive the screw.

Fix 2: Check the frame with a level. Place a 2-foot level on the door jamb (the vertical part of the frame). If the bubble shows the jamb leaning toward the room, the door will swing inward. Shim behind the top hinge to push the door away from the room, or behind the bottom hinge to pull it the other way. Cardboard from a cereal box works for thin shims; use wood shims for gaps over ⅛ inch. Remove one screw at a time, insert the shim, then replace the screw.

What causes a door to sag and not close properly?

Worn hinge pins or bent hinge leaves let the door drop on the latch side, so the latch bolt hits the strike plate too high or too low instead of sliding into the hole. You'll see a gap at the top of the door on the hinge side and the door rubbing the frame at the bottom on the latch side.

Fix 3: Replace the hinge pins. Most residential hinges use removable pins. Tap the pin out from the bottom with a nail and hammer, pull it free, and compare it to a new pin from a hardware store. If the old pin is bent or worn smooth (no knurling), replace all pins on the door at once—mixing old and new creates uneven friction. Cost: under $5 for a 3-pack.

Fix 4: Add a third hinge. Solid-core doors and doors over 80 inches tall need three hinges to prevent sag. Measure the distance between the existing two hinges, divide by 2, and install the third hinge at that midpoint. Use a chisel to mortise the jamb and door edge so the hinge sits flush.

If you're replacing ceiling light fixtures in the same room, check whether the door frame shifted when the house settled—the two often happen together.

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

A latch that won't catch means the strike plate (the metal rectangle on the door jamb with the hole for the latch bolt) is misaligned. Close the door slowly and watch where the latch hits the plate. If it's too high, too low, or hitting the edge of the hole, the frame has shifted or the door has sagged.

Fix 5: File the strike-plate hole. Use a metal file to enlarge the hole vertically or horizontally by 1⁄16 to ⅛ inch, whichever direction the latch misses. Test after every few file strokes—stop when the latch slides in smoothly.

Fix 6: Move the strike plate. If filing won't reach the latch, unscrew the strike plate, fill the old screw holes with wood filler, and re-mount the plate ⅛ inch higher or lower. Use a chisel to extend the mortise so the plate sits flush. This fix works best when the door has sagged more than ¼ inch.

When should I replace the entire hinge instead of adjusting it?

Replace the hinge if the knuckles (the barrel part) are cracked, the leaves are bent beyond straightening, or rust has frozen the pin. Steel hinges last 20–30 years in dry climates; brass and bronze last longer. In coastal or high-humidity areas, check hinges every 5 years for corrosion.

Hinge sizing matters: Match the height and width of the old hinge. Standard interior doors use 3½-inch hinges; exterior and heavy doors use 4-inch. Buy hinges with a removable pin unless local code requires non-removable (fire-rated) hinges for certain applications.

Pair this repair with an annual chimney and fireplace inspection if you have one—both are low-cost preventive checks that avoid bigger problems.

FAQ

How long does it take to fix a door that won't stay open?

15–30 minutes for loose screws or hinge shimming; up to an hour if you need to move the strike plate, replace all hinge pins, or add a third hinge. Gather your tools first: screwdriver, level, shims, wood filler, and a metal file.

Can I use a doorstop instead of fixing the door?

A wedge doorstop hides the problem but doesn't fix the underlying sag or frame shift. If the door swings shut hard enough to hurt someone or damage the wall, fix the hinges and alignment—a doorstop won't prevent injury or further wear.

Do I need to remove the door to tighten hinge screws?

No. Work with the door in place. Open it fully, prop the bottom with a book or piece of wood to take weight off the hinges, then tighten screws one hinge at a time. Remove the door only if you're replacing all three hinges or planing the edge.

Why does my door swing open in summer and stay put in winter?

Humidity causes wood to swell, which can change the door's center of gravity and how it hangs in the frame. If the problem is seasonal and mild, adjust the stop bead (the thin wood strip on the jamb that the door closes against) rather than shimming hinges—you may need to reverse the adjustment in six months.

Should I hire a carpenter for this repair?

Only if the door frame is severely out of square (more than ½ inch over 6 feet), the jamb is split, or you've tried all four fixes and the door still won't stay. A carpenter will charge $100–200 to rehang a door or replace a jamb; shimming and screw replacement are straightforward DIY tasks.

This is educational information, not professional carpentry or structural advice. If your door frame has shifted due to foundation movement or you see cracks in walls near the door, consult a licensed contractor or structural engineer.
