Humidity and Seasonal Swelling
Wood doors absorb and release moisture with the seasons, expanding slightly in humid months and shrinking back in dry ones. In shore-area homes, this effect is often more pronounced than inland because of consistently higher ambient humidity from salt air, especially in homes without central air running year-round. A door that sticks badly in summer but swings freely by fall is very likely a humidity issue rather than a structural one.
If that's the pattern, the fix is usually minor: a light sanding of the binding edge, or better ventilation and humidity control in the room, rather than rehanging the door.
Hinges Are the First Thing to Check
Loose hinge screws let a door sag slightly, which throws off the gap around the whole frame and causes binding at a corner rather than the whole edge. Tightening the screws, or replacing stripped screw holes with longer screws that reach the framing behind the jamb, resolves a large share of sticking-door complaints without touching the door itself.
Worn or bent hinges, or a door that's been rehung crooked in the past, can cause similar symptoms and may need a hinge replacement rather than just a tightening.
- Door drags along the bottom near the latch side — hinge sag or settling
- Door binds only at the top corner — often a loose top hinge
- Sticks all around evenly — likely humidity/swelling
- Latch doesn't line up with the strike plate — frame has shifted
When It's the House, Not the Door
Older and shore-front homes settle over time, and that shift can rack a door frame out of square so the door binds no matter the season. Cracks in the drywall above the door frame, a gap that's uneven from top to bottom, or multiple doors on the same side of the house sticking are signs of structural settling rather than a simple hardware fix.
Minor settling can often be corrected with frame adjustment and door planing, but noticeable or ongoing settling, especially paired with foundation or sill concerns common in older shore properties, is worth having assessed by someone who can evaluate the structure itself.
Fixing It the Right Way
Planing a door — shaving down the binding edge — should be done conservatively and evenly, and only after confirming hinges and humidity aren't the real cause, since removing too much wood is not reversible and can leave a visible gap once seasons change again.
