Steps

Goal: Confirm where the door sticks, then rule out hinge issues before isolating paint buildup, swelling, or warp.

  • Open and close the door several times. Note where it binds—top corner, bottom, or latch side.
  • Good: It sticks in one or more spots—proceed to Check hinges.
  • Bad: The door will not latch or stay open—different problem; see the relevant guide.

Check hinges

Goal: Fix loose hinges or bent pins so the door swings freely.

  • Lift the door by the handle. If it moves up and down, the hinges are loose. Tighten all hinge screws with a screwdriver—use the longest screws that fit.
  • Remove a hinge pin by tapping it up from the bottom. Check for rust, bends, or wear. Replace with a matching pin if damaged.
  • Good: The door swings more freely after tightening or replacing pins—you may be done.
  • Bad: Still sticks—proceed to Paint buildup and swollen wood.

Paint buildup and swollen wood

Goal: Remove paint buildup or sand swollen spots so the door clears the frame.

  • Look at the door edge and the frame where the door meets it. Run your finger along the seam—paint buildup or swollen wood feels rough or raised.
  • If paint buildup: scrape or sand the high spots with a paint scraper or 120-grit sandpaper. Remove only enough to clear the frame.
  • If swollen from humidity: sand the high spots lightly. If the wood is warped (rocks or does not sit flat), do not sand—call a carpenter.
  • Good: The door clears the frame and swings smoothly—done.
  • Bad: Warped or sanding did not help—call a carpenter or handyman.

Shim hinges

Goal: Correct door sag by shimming the hinge so the door aligns with the frame.

  • If the door sags and binds at the top or bottom, shim the hinge: remove the hinge from the jamb, add a thin cardboard or wood shim behind the hinge leaf on the side that needs adjustment, reinstall.
  • Test the door. Good: The door aligns and swings without binding—done.
  • Bad: Still sticks—call a carpenter or handyman.

When to get help

Call a carpenter or handyman if:

  • The door or frame is warped.
  • You have tried tightening hinges, replacing pins, removing paint, and sanding and it still sticks.
  • The door is heavy commercial-grade or fire-rated.

Do not force a stuck door—it can damage the frame or hinges. For related fixes, see Fix a door that will not latch or Fix a drawer that sticks.

Verification

  • The door opens and closes smoothly without catching.
  • No binding at the top, bottom, or latch side.
  • Hinge screws are tight and the door does not shift when you lift it.
  • The door swings freely through its full range.
