FAQs
Doors rarely start sticking for no reason.
Usually, the problem develops gradually as hinges loosen, wood swells from humidity, paint layers build up, or the house settles slightly over time.
The good news is that most sticking doors can be repaired without replacing the door or frame. The key is identifying exactly where the door rubs and understanding why it’s happening before you start sanding or planing.
Quick Answer
A sticking door is usually caused by:
- Loose or sagging hinges
- Humidity swelling the wood
- Paint buildup along the edges
- House settling
- A door dragging on carpet or flooring
- Warped door components
In many cases, tightening the upper hinge screws or replacing one screw with a longer screw solves the problem without sanding or trimming the door.

Don’s Advice
One of the most common mistakes homeowners make is immediately sanding or planing a sticking door before checking the hinges.
I’ve seen many doors unnecessarily trimmed when the real problem was simply loose hinge screws allowing the door to sag slightly inside the frame.
Why Doors Start Sticking
Wood doors naturally expand and contract slightly as humidity changes throughout the year.
At the same time:
- Hinges loosen from years of use
- Homes settle gradually
- Paint layers accumulate
- Carpet or flooring heights change
Even a small shift can change the narrow gap—called the reveal—between the door and jamb.
Common symptoms include:
- The door rubs at the top corner
- The latch side sticks
- The door drags across carpet
- The door becomes hard to latch
- The door sticks only during humid weather
- The edge scrapes paint from the jamb
The location of the rubbing usually helps identify the underlying problem.
How to Diagnose Where the Door Binds
Before fixing the door, determine exactly where it rubs against the frame.
Open and close the door slowly while watching the gap between the door and jamb.
The reveal should remain fairly even around the top and sides.
Look for:
- Areas where the gap narrows or disappears
- Scrape marks on paint
- Shiny worn spots
- Carpet drag marks
- Binding near the latch or hinges
A simple way to locate tight spots is to slide a thin strip of cardboard between the door and jamb while slowly moving it around the perimeter.
Where the cardboard catches, mark the area lightly with pencil.
| Where the Door Rubs | Likely Cause |
|---|---|
| Top latch-side corner | Loose upper hinge or sagging door |
| Entire latch side | Humidity swelling or paint buildup |
| Bottom edge | Loose hinges or flooring interference |
| Top edge | House settling or frame movement |
| Only during humid weather | Wood expansion from moisture |
Fix Loose or Sagging Hinges
The most common cause of a sticking interior door is hinge sag.
The upper hinge supports most of the door’s weight. Over time, the screws can loosen slightly inside the framing behind the jamb.
Even a small amount of sag may cause the opposite top corner to bind against the frame.
1. Tighten the Existing Screws
Start by tightening all hinge screws firmly with a screwdriver.
Pay particular attention to the upper hinge.
If a screw spins without tightening, the hole has probably stripped and no longer grips the wood securely.
2. Replace One Upper Hinge Screw With a Longer Screw
Remove one screw from the upper hinge leaf attached to the jamb.
Replace it with a 2 1/2-inch or 3-inch wood screw.
Unlike the short factory screws, a longer screw reaches into the framing behind the jamb and can pull the entire door back into alignment.
As you tighten the screw, watch the reveal around the door. You can often see the upper corner move back into position.
Don’s Advice
When driving long hinge screws, tighten gradually and check the door frequently.
It’s surprisingly easy to over-correct the alignment and create a new rubbing point elsewhere.
3. Repair Stripped Screw Holes
If the screws no longer grip properly:
- Remove the loose screw
- Pack the hole with glue-coated toothpicks or wood dowels
- Allow the glue to dry
- Reinstall the screw
This gives the screw fresh wood to bite into.

How to Fix a Door That Swells From Humidity
Wood doors absorb moisture from humid air, especially if the edges are unfinished or poorly sealed.
This expansion can make a previously smooth-fitting door suddenly bind during humid weather.
Common signs of humidity swelling include:
- The door sticks mainly in summer
- The sticking worsens after rain
- The latch side becomes uniformly tight
- The problem improves during dry weather
Before sanding or trimming the door, first try:
- Running a dehumidifier nearby
- Improving ventilation
- Cleaning paint buildup from the jamb
- Applying paraffin or paste wax to rubbing surfaces
Sometimes reducing friction is enough to solve the problem without altering the door.
How to Plane a Door
Planing and sanding techniques are intended primarily for wood doors, including solid-wood doors and most painted hollow-core interior doors with wood or hardboard skins. Steel doors should never be planed, and fiberglass doors generally require different repair methods. Some laminate or composite doors also can be damaged by aggressive sanding or trimming, so check the manufacturer’s recommendations before modifying those materials.
If hinge adjustments don’t solve the problem, you may need to remove a small amount of material from the rubbing edge.
Always remove as little wood as possible.
Most sticking doors require only minor correction.
1. Mark the High Spots
Use pencil marks to outline the rubbing areas.
Avoid guessing where to remove material.
2. Remove the Door
For heavier trimming, remove the door and support it securely on sawhorses or edge supports.
See:
How to Remove a Door
3. Sand Minor Rubbing Areas First
For slight sticking, coarse sandpaper wrapped around a sanding block may solve the problem without planing.
Sand evenly and check the fit often.
Then smooth the area with finer sandpaper.
4. Plane the Edge Carefully
If more material must be removed, use a sharp jack plane set for shallow cuts.
Plane with the wood grain whenever possible to avoid gouging or tear-out.
At the top and bottom rails, work from the outside edge toward the middle.
This helps prevent splitting the wood at the corners.
5. Test the Fit Frequently
Rehang the door periodically and check the clearance.
Typically, you should maintain approximately the thickness of a dime between the door and jamb.
Avoid removing too much material too quickly.
6. Seal the Bare Wood
After sanding or planing:
- Prime exposed wood
- Paint or seal the edge
Unsealed wood absorbs moisture more easily and may swell again later.
Don’s Advice
Be especially careful about trimming exterior doors during humid weather, when moisture causes them to expand.
Wood often shrinks again during drier seasons, and over-planing can leave ugly air gaps that hurt energy efficiency and weather sealing.

How Paint Buildup Causes Doors to Stick
Repeated repainting gradually reduces the narrow clearance around a door.
This is especially common in older homes where doors and trim have been painted many times over decades.
Look for:
- Paint ridges
- Drips along the edges
- Heavy paint layers near the jamb
- Bridging where paint bonds the door to the trim
Often, removing excess paint solves the problem without sanding the wood itself.
Use a sharp wood chisel held nearly flat against the surface to carefully shave away heavy buildup.
Then smooth lightly with fine sandpaper.
How to Fix a Door That Drags on Carpet
If the door drags across carpet or flooring, the problem may not be the door itself.
Common causes include:
- New thicker carpet or padding
- Added flooring layers
- Loose hinges allowing the door to sag
- Minor settling of the structure
Before trimming the bottom edge, always try tightening the hinges first.
Often this raises the door enough to restore clearance.
If trimming becomes necessary, remove only a small amount from the bottom edge and reseal the exposed wood afterward.
When NOT to Plane a Door
Sometimes planing is the wrong solution.
Avoid removing wood if:
- The hinges are loose
- The house is actively settling
- The problem occurs only during short humid periods
- Paint buildup is causing the rubbing
- The frame itself is out of square
Exterior doors especially should be adjusted carefully because excessive gaps can create:
- Air leaks
- Water intrusion
- Poor weatherstripping contact
- Security problems
How to Prevent Doors From Sticking Again
- Tighten hinge screws periodically
- Keep door edges painted or sealed
- Control indoor humidity when possible
- Lubricate hinges occasionally
- Clean paint buildup before it becomes severe
- Maintain weatherstripping on exterior doors
FAQs
Why does my door stick only in summer?
Humidity causes wood fibers to absorb moisture and expand slightly, reducing the clearance between the door and frame.
Should I sand or plane a sticking door?
Minor rubbing can often be corrected with sanding. Heavier binding usually requires careful planing.
Can loose hinges really cause a door to stick?
Yes. Even slight hinge sag can shift the opposite upper corner into the jamb.
How much clearance should a door have?
Typically, about the thickness of a dime around the sides and top is sufficient for smooth operation.
Why is my door suddenly dragging on carpet?
New flooring, thicker carpet padding, loose hinges, or settling can reduce bottom clearance.
