Houses move with the climate: Heat and moisture will make them expand, cold and dryness will make them contract. This movement is normal and in most cases will not cause cracks.
What do horizontal cracks in walls mean?
Horizontal Cracks If the crack is horizontal or runs at a jagged 45-degree angle, it might mean there’s a more serious problem such as severe foundation shifting or water damage. Surface-blemish cracks can often be repaired with drywall putty, sanding tools and a fresh coat of paint.
