What Causes the ‘Creak’ of an Old Door?

When you open an old door and it creaks, it's because parts of the door are moving in a special way that makes a sound.

Think of your door like a big, sleepy animal. When it’s new, it moves smoothly, just like when you first learn to walk. But over time, the door and the frame (the part around the door) get tired or a little out of shape.

If the door isn’t perfectly aligned with the frame, parts of it rub against each other when you open or close it. This rubbing is like when your sock catches on your shoe, it makes a creak sound!

Old doors are usually made of wood, and wood can shrink or swell depending on how wet or dry the air is. When the door gets smaller, it might not fit as nicely in its spot anymore. That’s like when you take off your sweater after being outside, it feels loose because it’s a little smaller now.

So next time you hear that creak, imagine the door giving a little yawn and stretch as it moves along with you!
