Signs Your Door Is Sticking

A sticking door usually gives you a few clues about what’s causing the problem.

Look for:

• The door requires extra force to open or close
• The top or side of the door rubs against the frame
• The bottom of the door drags across the floor
• The door sticks more during humid weather
• You can see scuff marks or worn paint where the door contacts the frame
• The gap around the door is noticeably tighter in one area
• The door has recently started sticking even though it worked normally before

A sticking door doesn’t automatically mean you need to sand or trim it. Loose hinges are one of the first things to check because they can cause the entire door to shift.

Before You Start

Open and close the door slowly and determine exactly where it is rubbing.

Look at the gap between the door and frame around the top and both sides. The gap should be reasonably consistent.

Pay attention to any area where the gap disappears or becomes noticeably smaller.

Also inspect the hinges before removing any wood.

Check for:

• Loose hinge screws
• A hinge pulling away from the door or frame
• Bent hinge leaves
• Stripped screw holes
• A door that appears to sag toward the latch side

💡 Pro Tip: Rub a pencil lightly along the edge of the door where you think it’s sticking. Open and close the door a few times. The rubbing area will often leave a visible mark that helps pinpoint exactly where material needs to be removed.

Step 1: Find Where the Door Is Sticking

Slowly close the door while watching the gaps around the top and sides.

Don’t force it shut.

Look for the exact point where the door first contacts the frame.

If you can’t see it clearly, inspect the door edge and frame for:

• Scraped paint
• Shiny spots
• Small dents
• Wood dust
• Dark rub marks

Mark the problem area lightly with a pencil.

What You Should See: Most sticking doors will have one relatively small area where the door edge is contacting the frame.

If Yours Looks Different: If the entire latch side of the door has an uneven gap or the top corner is noticeably lower than it should be, check the hinges before sanding anything. The door may be sagging. See How to Fix a Sagging Door for a more complete walkthrough.

Step 2: Tighten the Hinge Screws

Open the door and check every screw on the hinges.

Use a screwdriver to snug any loose screws.

Start with the top hinge, since it carries much of the load that keeps the door properly aligned.

Don’t overtighten the screws. Tighten them until the hinge sits firmly against the wood.

Close the door and test it again.

Sometimes this simple adjustment is all it takes.

What You Should See: The hinge leaves should sit flat against the door and frame without moving when the door opens or closes.

If Yours Looks Different: If a screw turns without tightening, the screw hole is probably stripped. Don’t keep spinning the screw. The hole will need to be repaired or the screw replaced with one that can reach solid wood.

Step 3: Correct a Sagging Door

If tightening the existing screws helped but the door still sags, inspect the screws in the top hinge on the frame side.

One of these screws can often be replaced with a 2½- to 3-inch wood screw that reaches through the jamb and into the framing behind it.

Drive the longer screw gradually while watching the door position.

The goal is to gently pull the hinge side of the frame tighter and raise the opposite side of the door slightly.

Stop once the hinge is secure and test the door.

Do not keep tightening the screw aggressively. Too much force can pull the jamb out of position.

What You Should See: The gap near the top of the door may become more even, and the latch-side corner may move slightly upward.

💡 Pro Tip: Test the door after every small adjustment. A surprisingly small movement at the top hinge can make a noticeable difference at the opposite corner of the door.

Step 4: Repair Any Stripped Hinge Screw Holes

If a hinge screw won’t tighten because the hole is stripped, repair the hole before moving on.

For a simple repair, remove the screw and insert one or more wooden toothpicks coated with wood glue into the hole.

Break or trim them flush with the surface.

Allow the glue to dry according to its instructions, then reinstall the screw.

For badly damaged holes, a more substantial wood repair may be necessary.

What You Should See: The screw should tighten securely and hold the hinge firmly against the wood.

If Yours Looks Different: If the wood around the hinge is cracked, split, or badly deteriorated, don’t rely on toothpicks alone. The damaged wood may need a more substantial repair.

Step 5: Test the Door Again

Before sanding or removing any wood, close the door several times.

Check whether tightening or repairing the hinges solved the problem.

If the door now closes normally, stop here. There’s no reason to remove material from the door.

If it still sticks, confirm exactly where it rubs and mark that area with a pencil.

This is important because you only want to remove material from the actual contact point.

Step 6: Sand the Sticking Area

For minor rubbing, start with sandpaper wrapped around a sanding block.

Sand the marked area using controlled, even strokes.

Remove a very small amount of material at a time.

After several passes, wipe away the dust and test the door.

Repeat only if necessary.

Avoid sanding a large section of the door when only a small spot is rubbing.

What You Should See: The marked contact area should gradually become smaller until the door clears the frame without rubbing.

If Yours Looks Different: If the door has a thick painted edge, sometimes paint buildup rather than the wood itself is causing the problem. Sand carefully so you don’t remove more material than necessary.

Step 7: Plane the Door if More Material Needs to Be Removed

If sanding isn’t enough and you have a solid wood or wood-edged door, a hand plane can remove material more efficiently.

Mark the area that needs adjustment.

Set the plane for a very shallow cut and make light passes along the door edge.

Work gradually.

Never try to remove the entire amount in one pass.

Depending on where the door sticks, removing the door from its hinges may make planing easier and safer.

💡 Pro Tip: Plane from the outside edges toward the center when working near the end of a wood door. This helps reduce the chance of splitting or chipping the corner.

If Yours Looks Different: Many hollow-core interior doors have only a limited amount of solid wood around their edges. Avoid aggressive planing or trimming because you can remove too much of the structural edge.

Step 8: Seal Any Exposed Wood

If sanding or planing exposes bare wood, especially on an exterior door, seal the area.

Apply primer and paint or another appropriate finish to match the existing door.

Bare wood can absorb moisture, which may cause the door to swell and start sticking again.

Allow the finish to dry before repeatedly closing the door against the frame.

For an interior door with only a tiny sanded area, touch-up paint may be all that’s necessary.

Step 9: Open and Close the Door to Test It

Open and close the door several times.

The door should move smoothly without rubbing, dragging, or requiring extra force.

Then close it completely and check that:

• The latch engages normally. If the door now swings freely but the latch still doesn’t line up with the strike plate, see How to Fix a Door That Won’t Latch.
• The gaps around the door look reasonably even
• The hinges remain tight
• The repaired area clears the frame
• The door doesn’t swing differently than it did before

If you removed material from the door, inspect the repaired edge once more and make sure any exposed wood has been properly sealed.

If the door still sticks in multiple areas despite proper hinge alignment, the door frame itself may be out of square or shifting.

🛑 Common Mistakes to Avoid

• Sanding before checking the hinges. A loose or sagging hinge can make a perfectly sized door rub against the frame.
• Removing too much material at once. Make small adjustments and test frequently.
• Forcing a sticking door closed. This can damage the paint, frame, latch, or door edge.
• Overtightening a long hinge screw. You can pull the jamb out of position if you drive it too aggressively.
• Ignoring stripped screw holes. A screw that spins freely isn’t supporting the hinge.
• Leaving bare wood unsealed. Exposed wood can absorb moisture and swell.
• Aggressively trimming a hollow-core door. These doors have limited solid material around their edges.

❓ FAQs

Why did my door suddenly start sticking?

Humidity is a common cause because wood can absorb moisture and expand. Loose hinges, settling, paint buildup, or changes in the frame can also cause a door that previously worked normally to start rubbing.

Should I sand a door that sticks?

Only after checking the hinges and alignment. If the door is properly aligned and only a small area rubs against the frame, light sanding is often the easiest fix.

How much should I sand off a sticking door?

As little as possible. Make a few passes, test the door, and repeat if necessary. Removing too much material can leave an excessive gap around the door.

Why does my door only stick in the summer?

Higher humidity can cause wood doors and frames to absorb moisture and expand. If the sticking is minor and seasonal, you may only need a very small adjustment.

Can I use a longer screw to fix a sagging door?

Often, yes. Replacing one of the frame-side screws in the top hinge with a 2½- to 3-inch wood screw can help pull the hinge toward the framing and correct minor sagging.

Why is my door rubbing at the top corner?

A loose or sagging top hinge is a common cause. Check and tighten the hinges before removing any material from the door.

Do I need to remove the door to sand it?

Usually not for minor rubbing along an accessible edge. If substantial planing or trimming is required, removing the door may make the work easier and give you better control.

📞 When to Call a Professional

Most sticking interior doors can be handled with basic tools and a little patience.

Consider calling a carpenter or handyman if:

• The door frame is visibly out of square
• The door suddenly began sticking severely
• Several doors in the house have recently started sticking
• The jamb is cracked, loose, or pulling away from the wall. If the problem is limited to movement between the frame and surrounding wall, see How to Fix a Loose Door Frame.
• An exterior door no longer closes or locks securely
• The door needs significant trimming
• The hinges or surrounding wood are badly damaged
• Adjusting the hinges and lightly sanding the contact point doesn’t solve the problem

If several doors or windows suddenly become difficult to open or close at the same time, especially along with new wall cracks or other noticeable movement, it may be worth having the underlying cause evaluated rather than repeatedly trimming the doors.
