help1. Understand the Problem

Wood is hygroscopic — it absorbs moisture from humid air and expands. When a door swells, it binds against the jamb or latch plate, making it hard to close. This is common in summer or after rain. The fix involves finding the tight spot and removing just enough material to restore clearance.

1
Mark the tight area
Mark the tight areaUse a pencil to trace the outline of the rubbing area on the door edge. This is where you'll sand or plane.
2
Sand the binding edge
Sand the binding edgeUsing 80-grit sandpaper on a sanding block, sand the marked area until the door closes freely. Sand in the direction of the wood grain.
3
Check the latch alignment
Check the latch alignmentIf the door still sticks, remove the strike plate and file the hole slightly larger in the direction of the bind.
4
Seal the bare wood
Seal the bare woodAfter sanding, apply a thin coat of primer and paint or polyurethane to the exposed wood to prevent moisture absorption.

Frequently Asked Questions

Will the door shrink back when humidity drops?expand_more
Usually yes — but repeated swelling and shrinking can crack the paint. Sanding and sealing prevents permanent damage.
How much should I sand off?expand_more
Start with 1/16 inch (about 1.5 mm). Sand a little, test the door, and repeat until it closes without force.
Can I use a plane instead of sandpaper?expand_more
Yes — a hand plane is faster for larger amounts. Set it for a very shallow cut and work from the edge inward.
What if the door still sticks after sanding?expand_more
Check if the hinges are loose or if the door frame is out of square. You may need to shim the hinges or call a carpenter.
