What is happenning when a house is making awkward sounds in fall?
When a house cracks it usually means that the wall on the outside of your house are shrinking because the air inside the house is taking less space. While the walls on the outside are shrinking, the walls on the inside are not. So the walls outside are making noises when they move around the walls on the inside to find their new shape while the ones on the inside keep the same shape/size. Also the walls inside the house are connected to the walls on the outside. So when the outside walls move, the inside walls also have to move so they crack while trying to stay with the outside walls.
