A sticking interior door is usually a small alignment problem, not a reason to replace the door. The most useful clue is where it catches. A door rubbing near an upper corner often points to a loose hinge or slight sag, while rubbing along the latch side may come from swelling, paint buildup, or a frame that is no longer perfectly square. Before sanding or planing anything, open and close the door slowly and watch the gaps around its edges.
Find the Exact Spot Where the Door Sticks
Close the door as far as it will comfortably go and inspect the reveal, the narrow gap between the door and frame. It should look reasonably even. If one section is much tighter, focus there first. You can slide a sheet of paper around the edge to locate resistance, then look for scuffed paint, shiny rub marks, compressed wood, or a clean contact line.
Pay attention to timing too. If the door sticks mainly during humid weather, moisture-related swelling is likely. If it began suddenly after years of normal use, loose hardware deserves attention first. This quick diagnosis prevents you from removing material in the wrong place.
Start With the Hinges Before Removing Wood
Loose hinge screws are among the simplest causes of a door rubbing the frame. Over time, the weight of the door can pull the upper hinge slightly away from the jamb. Even a small movement can lower the latch-side corner enough to cause rubbing.
Tighten the Hinge Screws Carefully
Use a screwdriver that fits the screw heads and tighten the screws on both the door and the jamb. Work one hinge at a time and test the door after each adjustment. Do not force screws that are already tight, because overtightening can strip the wood and make the problem worse.
For example, imagine a bedroom door scraping near the upper latch-side corner. If the top hinge has loosened, tightening those screws may lift the outer edge just enough to restore clearance. This is often the best first interior door adjustment because it improves alignment without cutting, sanding, or refinishing anything.
Repair a Stripped Screw Hole
If a hinge screw spins without tightening, the wood in the hole may be stripped. The hole can be repaired with glued wood material so the screw has solid fibers to grip again. In some jamb situations, a suitable longer screw can reach sound framing behind the jamb. Use the correct screw for the hinge and avoid driving extra-long screws blindly where concealed services could be present.
Check for Paint Buildup
Doors that have been repainted several times can lose clearance even when the wood has barely moved. Thick paint along the door edge, jamb, or stop may create a stubborn contact point. If you can see a raised paint ridge exactly where the door rubs, carefully smoothing the buildup may solve the problem without sanding the underlying wood.
Touch up exposed areas with a compatible primer and finish coat. Sealing bare wood helps limit moisture absorption and reduces the chance that the same edge will swell and begin sticking again.
Allow for Humidity and Seasonal Swelling
Wood expands and contracts as moisture conditions change. An interior door may fit perfectly during a dry season and become tight when indoor humidity rises. Bathrooms, laundry areas, and poorly ventilated rooms are especially prone to this pattern.
If the problem is seasonal, avoid aggressive trimming at the first sign of swelling. Better ventilation or a dehumidifier may reduce the sticking without permanently enlarging the gap. If material eventually must be removed, take off only enough to let the door move freely. Removing too much can leave an obvious gap when the door shrinks in drier weather.

Sand or Plane Only the Confirmed High Spot
When the hinges are secure and moisture is not the only cause, a localized high spot may need sanding or planing. Mark the rubbing area first. Remove the smallest amount of material possible, then test the door. Several light passes are safer than one aggressive cut.
If you expose bare wood, prime and paint or otherwise seal the edge after the fit is correct. A controlled sticking door fix should improve clearance without creating a visibly oversized gap around the frame.
Check the Latch and Strike Plate Separately
Sometimes a door swings freely but resists during the final inch of closing. That can mean the latch is hitting the strike plate rather than the door rubbing the frame. Look for fresh scratches on the plate and check whether the latch enters the opening cleanly.
Small misalignment can sometimes be corrected by tightening hardware or carefully repositioning the strike plate. If the door is visibly sagging, fix the hinges first. Moving the strike plate to compensate for a sagging door may hide the symptom while leaving the real door alignment repair unresolved. A separate guide on how to adjust a door strike plate would make a natural internal link here.
Know When the Frame May Be the Problem
A door that develops large uneven gaps, sticks in several places, or sits in a visibly distorted opening may need more than a simple hardware adjustment. Buildings can settle, and moisture damage can affect framing or trim. If several nearby doors or windows begin binding at the same time, or cracks around the opening are changing noticeably, investigate the wider cause before trimming individual doors.
For normal maintenance, a guide on how to fix loose door hinges is another useful companion resource because hinge wear is one of the first issues to rule out when an interior door changes position.
FAQ
Why does my interior door suddenly stick?
Common causes include loose hinge screws, seasonal moisture changes, paint buildup, or small shifts in the frame. Find the exact contact point before choosing a repair.
Should I sand a sticking door right away?
No. Tighten the hinges and confirm the rubbing point first. If humidity is causing temporary swelling, removing too much wood can create an excessive gap later when conditions become drier.
Can a sticking door indicate a structural problem?
It can, but most sticking interior doors have simpler causes. Structural movement is more concerning when the frame is visibly distorted, cracks are growing, or several doors and windows start binding around the same time.
How much should I remove when sanding a door?
Remove as little as necessary. Mark the contact area, make a few light passes, and test frequently. Once the door swings freely, seal any exposed wood rather than continuing to remove material.
A Small Adjustment Is Often Enough
The best way to fix a sticking interior door is to diagnose before cutting. Start with the hinges, inspect paint and moisture conditions, check latch alignment, and remove wood only from a confirmed high spot. Most cases can be solved with careful observation and a restrained adjustment, preserving the fit of the door and avoiding unnecessary carpentry.
