Quick Answer
A sticking wood door is often caused by swelling, loose hinges or paint buildup, but frame movement and latch alignment can produce similar symptoms. Tighten and inspect the hinge screws first; it is a common cause. If still tight, identify where the door rubs by closing it slowly, then sand or plane those exact spots. Avoid removing more than 1/16 inch at a time.

Save to PinterestA sticking wood door that drags on the frame, refuses to latch, or has to be shoved to close is a common household irritation, especially as the seasons change. The good news is that a sticking door is usually a quick fix once you work out where and why it is binding, and you rarely need more than a few basic tools.
This guide walks you through finding exactly where the door sticks and the best fix for each cause, from tightening hinges to planing a binding edge, so your door opens and closes smoothly again.
Why Wood Doors Stick
Wood is sensitive to moisture and movement, so doors bind for a handful of common reasons:
- Humidity and swelling: Wood absorbs moisture in damp or humid weather and swells, causing the door to rub, often easing again when it dries.
- Loose hinge screws: Loose screws let the door drop and shift, so it catches on the frame, a very common and easily fixed cause.
- Built-up paint: Layers of old paint on the edges thicken the door so it no longer fits the frame.
- Settlement: The frame can shift slightly as the house settles, throwing the door out of alignment.
Tools and Materials You Will Need
- Screwdriver and longer screws
- Pencil
- Plane or coarse sandpaper/sanding block
- Candle or wax (for lubrication)
- Paintbrush and matching paint
- Cardboard (for shimming hinges)
Step-by-Step: How to Fix a Sticking Wood Door
Step 1: Find Where It Sticks
Close the door slowly and watch where it rubs, or slide a piece of paper around the gap to find the tight spot. You can also look for a worn, shiny, or scuffed mark on the door edge or frame.
Step 2: Tighten the Hinge Screws
Before anything drastic, tighten all the hinge screws. If the door has dropped, replace one or two top-hinge screws with longer ones that reach into the frame stud to pull the door back up. This alone fixes many sticking doors.
Step 3: Try Lubricating and Easing First
If the door only sticks slightly, rubbing a candle or wax on the rubbing edge can ease it. If swelling from humidity is the cause, it may free up on its own once the air dries.
Step 4: Sand or Plane the Binding Edge
For a persistent rub, mark the tight area, then sand or plane a small amount off that edge. Remove only a little at a time and re-test often, you can always take more off, but not put it back.
Step 5: Seal and Repaint the Edge
Once it closes smoothly, seal any bare wood you exposed with primer and paint. Sealing the edge also helps stop the wood absorbing moisture and swelling again.
Pro Tips to Prevent This Problem
- Always start by tightening hinge screws, it is the easiest fix and can correct sticking caused by hinge movement.
- Remove material gradually when sanding or planing and test often, to avoid taking off too much.
- Seal and paint any bare edges so the wood does not absorb moisture and swell again.
When to Call a Professional
Call a carpenter if the door or frame is badly warped, if the frame has shifted significantly due to settlement, or if you are dealing with a fire door, which must not be altered in ways that affect its rating. A significantly out-of-square frame may need professional realignment.
Frequently Asked Questions
Why does my door only stick in summer or when it is humid?
Wood absorbs moisture and swells in humid weather, so the door rubs, then shrinks back as the air dries. If it only sticks seasonally, sealing the edges helps, and you may not need to remove much material at all.
How do I fix a door that has dropped and catches?
A dropped door is usually down to loose hinge screws. Tighten them, and replace a top-hinge screw or two with longer ones that bite into the frame stud to lift the door back into alignment.
How much should I sand off a sticking door?
Only a little at a time. Mark the tight spot, remove a small amount, and re-test repeatedly. Taking off too much leaves a permanent gap, so patience is key.
Final Thoughts
A sticking wood door is usually a quick, satisfying fix. Find exactly where it binds, tighten the hinge screws first, and only sand or plane the edge if needed, removing material gradually. Seal any bare wood so it will not swell again. With these steps your door will swing and latch smoothly, and you will leave only badly warped doors or fire doors to a professional.
