Look for patterns
Is the crack vertical, horizontal, or shaped like stair steps? Does water come through it? Take dated photos with a ruler beside the crack so you can compare them over time. One measurement alone cannot tell you whether movement is happening.
Repair depends on the cause
A specialist may recommend sealing the crack, injecting repair material into it, improving drainage, or adding structural reinforcement to support the wall or foundation. Sealing a crack may help with water entry, but it may not stop the movement that caused it.
