A door that suddenly scrapes, jams, or refuses to latch can make a small daily task surprisingly frustrating. The good news is that sticking usually has a clear cause, and many fixes are simple once you know where to look. The key is to notice when the problem happens and exactly where the door rubs—those clues can help you tell a quick hinge adjustment from a sign of moisture or movement in the house.

Why a door stops moving freely
A door needs a small, even gap between its edges and the frame. If the door, frame, hinges, or latch shifts enough to close that gap, the door may drag or stick. Sometimes the change is only a fraction of an inch, but that can be enough to affect a close-fitting door.
Doors can also stick for more than one reason. A slightly loose hinge may get worse as a wooden door swells in humid weather, for example. Before making repairs, open and close the door slowly and look for the spot where it first touches the frame or floor.
Common causes of a sticking door
Changes in humidity and temperature
Wood takes in moisture from the air and releases it as conditions change. In humid weather, a wooden door can swell, making it wider or thicker. It may then rub along the top, side, or bottom of the frame. When the air dries out, the door may shrink and move freely again.
This is common with solid wood doors and can also affect wood frames. Seasonal sticking that improves when the weather changes often points to moisture rather than a sudden structural problem. Still, don’t assume every seasonal issue is harmless: persistent swelling may be caused by a leak or poor ventilation.
Loose or worn hinges
Hinges carry the door’s weight. If their screws loosen, the door can sag slightly, changing the gap around it. A sagging door often rubs at the top corner on the latch side, or it may drag along the floor.
Hinges can also wear out, bend, or pull away from soft or damaged wood. A quick check is to lift the handle side of the open door gently. If it moves noticeably, the hinges or their screw holes may need attention. Don’t force it; excessive movement can damage the frame.
A shifted door frame or house movement
Frames can move when a house settles, when building materials change with moisture, or after nearby construction or renovation. If the frame becomes slightly out of square, the gap around the door won’t be even. The door may bind in one area even though the hinges look secure.
One clue is that several doors or windows in the same part of the home have started sticking. You might also see new cracks around door or window openings. These signs don’t automatically mean there’s a serious structural issue, but if the changes are sudden, spreading, or paired with large cracks, ask a qualified building professional to inspect them.
Paint or finish buildup
Repeated coats of paint can narrow the space between the door and frame. The buildup may be hard to notice until the door is painted again or the humidity rises. Paint can also create a sticky surface where the door catches as it opens or closes.
Look for thick, cracked, or shiny paint marks at the contact point. If paint is the cause, carefully removing a small amount from the rubbing area may help. Take care with older paint: homes built before 1978 may contain lead-based paint in the United States, so sanding or scraping can create a health hazard. Use local safety guidance or hire a qualified professional before disturbing old paint.
Flooring changes or a new rug
New carpet, thicker underlay, a raised threshold, or a rug placed in the door’s path can make the bottom edge drag. Even a small change in floor height may be enough to stop the door from swinging freely.
Check the full path of the door, including the hinge side and the area beneath it. If the door only sticks after new flooring or a rug was added, the timing is a useful clue. Don’t trim the door until you’ve confirmed that the floor covering or threshold is correctly installed.
A misaligned latch or strike plate
Sometimes the door swings without rubbing but won’t latch. In that case, the latch bolt may no longer line up with the hole in the strike plate—the metal plate on the frame. Loose hinges, a sagging door, or a shifted frame can cause that misalignment.
Close the door slowly and watch the latch. If it hits the edge of the strike plate instead of entering the opening, the problem is likely alignment rather than swelling. A latch that sticks even when the door is open may instead need cleaning, adjustment, or replacement.
A leak or excess moisture
Water can make a door or frame swell, especially near a bathroom, kitchen, exterior entrance, or laundry area. Check for soft wood, bubbling paint, dark stains, a musty smell, or dampness around the frame. A door that continues to swell after the weather changes deserves a closer look for leaks or poor drainage.
Fixing the door without fixing the moisture source is usually temporary. The material may swell again, and ongoing dampness can lead to rot or mold. If you find signs of water damage, address the source before sanding or shaving the door.
How to find the exact sticking point
Start with a simple inspection rather than adjusting several things at once. Open and close the door slowly, paying attention to when resistance begins. Look for rub marks, scraped paint, or a shiny patch on the door edge or frame.
- Check the top and side gaps. A gap that narrows at one corner may point to sagging or a shifted frame.
- Look along the bottom edge. Scrape marks can point to a rug, floor covering, threshold, or sagging hinges.
- Test the latch separately. If the door moves freely but won’t latch, inspect the latch and strike plate alignment.
- Notice when it happens. A problem that appears during humid weather may have a different cause from one that starts right after new flooring.
You can also close the door gently and check whether a sheet of paper slides through the gap. If it slips easily in one area but catches in another, the clearance isn’t even. This won’t tell you the cause by itself, but it can help you locate where the door is binding.
What you can try before calling a professional
Tighten hinge screws
If the door is sagging and the hinges are loose, tighten the screws with a screwdriver. Stop if a screw turns without gripping or if the wood around it is damaged. A longer screw may help anchor a hinge into the framing behind the jamb, but the right length and placement matter; a screw that’s too long can damage nearby materials.
Clean and lubricate the hinges
If the door squeaks or feels stiff at the hinge rather than rubbing the frame, cleaning and lubricating the hinge pin may help. Use a lubricant suitable for door hardware and apply a small amount, then open and close the door several times. Wipe away excess so it doesn’t collect dust or stain the door.
Adjust the strike plate
If the latch misses the strike plate slightly, check that the plate’s screws are tight. Minor alignment problems may be corrected by adjusting the plate, but avoid enlarging the opening before you understand why the door has shifted. If the door is sagging, correcting the hinge problem may bring the latch back into line.
Wait before trimming a swollen door
It can be tempting to plane or sand a swollen wooden door right away. If humidity is the cause, the door may shrink again when conditions change, leaving an oversized gap. First check for leaks and consider whether the problem is seasonal. If trimming is still needed, remove as little material as possible and seal the exposed wood afterward to help limit future moisture changes.
When to get expert help
Call a carpenter or door repair professional if the door is badly sagging, the frame is cracked, a hinge is pulling out, or the door remains stuck after basic adjustments. A professional can check whether the frame is out of square and decide whether the door, hinges, or jamb need adjustment.
Get a building professional’s advice if several doors start sticking at once, the change is sudden, or you notice widening cracks or other signs of movement. For a swollen door near a leak, fix the water problem first. And if an exit door is difficult to open, treat it as a safety issue rather than a minor annoyance.

Frequently Asked Questions
Why does my door stick only in summer?
Higher humidity can make wood absorb moisture and swell. That can reduce the clearance between the door and frame. If the sticking is severe or continues through dry weather, check for a leak or another source of dampness.
Why does a door stick at the top corner?
A top corner on the latch side often rubs when the door sags because of loose or worn hinges. Look for loose screws and uneven gaps. If the frame is also shifting or cracked, have it inspected.
Should I sand or plane a sticking door?
Only after you’ve found the cause. If humidity is making the door swell, removing wood too soon may leave a large gap when it dries. Check the hinges, floor, paint, and signs of moisture first.
Why does my door close but not latch?
The latch may be missing the strike plate because the door has sagged or the frame has moved. If the door swings freely, watch where the latch bolt meets the plate. If the latch sticks even with the door open, the hardware itself may need attention.
Conclusion
Doors usually stick because something has changed: the wood has swollen, a hinge has loosened, paint or flooring has reduced the clearance, or the frame has shifted. Find the exact rubbing point and consider when the problem began before making repairs. A small hinge adjustment may be all you need, but signs of water damage, major movement, or a door that blocks an exit call for a more careful fix.
