Cracks are usually what make people call. Some are harmless shrinkage; others are the first sign the foundation is moving. The pattern says a lot.

Reading the cracks
| Crack | Often means |
|---|---|
| Hairline cracks in a slab or drywall | Common shrinkage; watch them |
| Stair-step cracks in brick | Movement worth evaluating |
| Cracks wider at one end | Uneven movement |
| Cracks that reopen after patching | Ongoing movement |
| Doors sticking near a crack | The frame is moving too |
Cost
Angi says minor cracks that don't affect structural integrity can cost as little as $250 to repair. If the crack is a symptom of movement, the repair is the movement, not the crack.
Track it
Mark the ends of a crack with a pencil and the date. If it grows past the mark in a few weeks, mention that when you ask for a quote.
