Steps

1
Open and close the door slowly to observe exactly where it is sticking. Use a pencil or painter's tape to mark the high spots on the door edge or jamb where rubbing occurs.
Tip: Check for scrape marks on the door edge to identify the contact point.

2
Inspect all hinges and tighten any loose screws using a screwdriver. If screws are stripped, fill the holes with toothpicks and wood glue before re-driving the screws for a secure hold.
3
If the door still sticks, attempt to realign it by replacing a middle hinge screw with a longer 2.5-inch or 3-inch screw to pull the hinge tighter toward the wall framing.

4
For doors that still rub, remove the door from its hinges. Use a hand plane or sanding block to gently shave off small amounts of material from the marked sticky areas.
Tip: Remove only the minimum required to avoid creating a gap that is too wide.

5
Reinstall the door and test the swing. If it still sticks, repeat the sanding or planing process, testing frequently until the door operates smoothly.
6
Smooth the trimmed area with fine-grit sandpaper. Apply wood filler to any chips, then finish the bare wood with matching paint or sealer to prevent future moisture swelling.
7
Verify that the door is square and has a consistent reveal (gap) of approximately 1/8 inch between the door and the jamb.

If the sticking is caused by structural foundation settlement rather than simple misalignment or swelling, consult a professional foundation repair specialist.

Pro Tips

  • Always mark the area to be sanded with a pencil for precision.
  • Work slowly and test the door's fit after every small adjustment to avoid over-removing material.
  • If the door swells during humid months, consider running a dehumidifier before altering the wood.

When to Call a Professional

If the door frame is out of square or the sticking returns after planing, the foundation may have shifted — consult a contractor.
