How to Fix a Sticking or Rubbing Door
Updated September 18, 2026
Can I do this myself?
Safe to DIY
Usually yes. Tightening hinges and light sanding are safe beginner jobs. Taking a heavy door off to plane it needs two people, and sanding old paint needs a lead test first. Sudden large gaps or new cracks point to house movement and need a professional.
A door that sticks, rubs or has to be shoved closed is usually telling you one of two things: either the wood has swollen with moisture, or the door has dropped out of position because its hinges have loosened. Both are common, and both are usually fixable with simple tools.
Humidity is the big seasonal culprit. Wood absorbs moisture from the air and expands, especially if the door’s edges were never painted or sealed. Many people notice doors sticking during wet seasons such as the monsoon or a humid summer, then working fine again in dry weather. Loose hinges, on the other hand, cause sticking all year and tend to get gradually worse.
Start with the least invasive fix. Tighten the hinges first, and only sand or plane the door if it still rubs. Remove as little wood as possible, and always seal the bare edge afterwards, or the door will soak up moisture and stick again. If the sticking appeared suddenly along with new cracks or large gaps, the building itself may be moving, which is a job for a professional.

Signs of the problem
- The door rubs the frame at the top corner or along the latch side
- You have to push or pull hard to open or close it
- Worn paint or shiny marks on the door edge or frame
- The door sticks in wet or humid weather but is fine when it’s dry
- The gap around the door is uneven: tight in one place, wide in another
- The bottom of the door scrapes the floor or threshold
Common causes
Swelling from humidity
Most commonWood expands as it absorbs moisture. Unsealed edges, especially the top and bottom that nobody sees, let moisture in. The door grows slightly and binds against the frame, typically worst during humid or rainy months.
Loose hinge screws
Most commonWhen the top hinge loosens, the door tilts, so its top corner on the latch side rubs the frame. A loose bottom hinge can do the opposite. Tightening the screws often fixes this completely.
Paint build-up
SometimesSeveral coats of paint on the door edge and frame add thickness. Eventually there’s no clearance left, and painted surfaces can even stick to each other in warm weather.
House settling or structural movement
Less commonBuildings settle over time, which can push a door frame out of square. Gradual, minor settling is normal. Sudden sticking with new diagonal cracks at the corners of doors or windows, or gaps that keep growing, can point to foundation or structural problems.
Safety first: before you start
- Critical:A door can weigh 20-40 kg (45-90 lb) or more. Get a helper to lift it off the hinges and carry it, and lift with your legs, not your back.
- Critical:In homes built before about 1980, paint may contain lead. Test the paint with a lead test kit before sanding or planing a painted edge, and don’t dry-sand it if the test is positive.
- Wear safety glasses and a dust mask (N95/FFP2) when sanding or planing.
- Keep fingers well clear of plane blades and power sander pads, and unplug power tools before changing blades or sandpaper.
- Lay the door on padded sawhorses or a stable surface so it can’t slip while you work on it.
Tools & materials
Tools
- Screwdrivers
- Pencil
- Sanding block or electric sander with 80- and 120-grit paper
- Hand plane or power planer (for larger amounts)
- Hammer and nail set (to remove hinge pins)
- Sawhorses or a padded work surface
- Safety glasses and N95/FFP2 dust mask
Materials
- Wood screws, around 65-75 mm (2.5-3 in)
- Wooden toothpicks and wood glue (for stripped holes)
- Primer and paint, or a clear wood sealer
- Lead paint test kit (for older homes)
Step-by-step fix
- 1
Find exactly where it sticks
Close the door slowly and watch for the point where it binds. Look for worn paint or shiny patches on the edge and frame. Slide a sheet of paper around the closed door: where it catches, the gap is too tight. Draw light pencil marks at those spots.

Tighten the hinges
Open the door and tighten every hinge screw. Replace stripped ones by packing the hole with glue-dipped toothpicks, or use a longer screw. On the top hinge, a 65-75 mm (2.5-3 in) screw through the frame into the wall framing pulls the top of the door back toward the hinge side, which often clears a rubbing top corner.
Warning: Check for switches and wiring in the wall beside the door before driving long screws.

Wait out a seasonal swell if possible
If the door only sticks in humid weather and the hinges are tight, consider waiting for a dry spell before removing any wood. A dehumidifier or fan can help. If you plane a swollen door, it may leave a large gap when it dries out.

Try light sanding in place
For minor rubbing, sand the marked area with 80-grit paper on a block, working along the grain, while the door is still hanging. Check the fit often. This is often enough to remove paint build-up.
Warning: Test old paint for lead first. If it contains lead, don’t sand or plane it yourself; use a professional trained in lead-safe work.

Remove the door for bigger jobs
If more than a couple of millimetres needs to come off, or the bottom edge rubs, take the door down. Close it, wedge the bottom, tap out the hinge pins from the bottom hinge up, then with a helper lift the door off and lay it on padded sawhorses.
- 6
Plane the edge
Mark a line where you need to remove wood, aiming for about a 3 mm (1/8 in) gap. Plane toward the line in light passes, working from the ends toward the middle on the top and bottom edges so you don’t split the corners. On the latch edge, avoid planing into the hardware; remove the latch first if needed.
Tip: It’s better to take off too little and repeat than too much. Test-fit between passes.

Seal the bare wood
Sand the planed edge smooth with 120-grit paper, wipe off dust, then prime and paint it, or apply a clear sealer on natural wood. Seal the top and bottom edges too while the door is off. Unsealed wood soaks up moisture and swells again.

Rehang and test
With your helper holding the door, line up the hinge knuckles and tap the pins back in, top pin first. Open and close the door several times and check that the latch still catches cleanly.

How to check it's fixed
- The door opens and closes with light hand pressure and no rubbing
- There is an even gap of roughly 3 mm (1/8 in) around the sides and top
- The latch catches without lifting or pushing the door
- All freshly planed edges are painted or sealed
When to stop and call a professional
- Doors suddenly stick along with new diagonal cracks in walls or large new gaps
- Several doors or windows have started sticking at the same time
- The frame is rotten, soft or separating from the wall
- Paint tests positive for lead and the edge needs sanding or planing
- The door is too heavy for you and a helper to handle safely
How to prevent it
- Seal all six sides of wooden doors, including the top and bottom edges.
- Keep indoor humidity moderate with ventilation, exhaust fans or a dehumidifier.
- Check hinge screws yearly and tighten them before sagging starts.
- Don’t paint the door edge with thick layers; lightly sand between coats.
Frequently asked questions
Why does my door stick only in the rainy season?
The wood absorbs moisture from humid air and expands. When the air dries out, it shrinks back. Sealing all edges of the door, including the top and bottom, greatly reduces this seasonal swelling.
Should I plane a swollen door?
Only after tightening the hinges and, ideally, after the swelling has partly gone down. Planing a fully swollen door can leave a large gap once it dries. Remove the minimum and seal the edge afterwards.
Can I sand a door without taking it off?
Yes, for small amounts on the latch side or top corner. For the bottom edge or larger amounts, removing the door is safer and gives a straighter result.
Is a sticking door a sign of foundation problems?
Usually not. Humidity and loose hinges are far more common. Be concerned if sticking appeared suddenly along with new cracks running diagonally from door or window corners, sloping floors, or gaps that keep getting bigger. Have a structural engineer or builder take a look.
Do I need to worry about lead paint?
In homes built before about 1980, paint can contain lead, and sanding or planing it creates harmful dust. Use an inexpensive lead test kit first. If it’s positive, leave the work to a lead-safe professional.
