A crack between the ceiling and wall. The ceiling joists and roof trusses have been designed to move up and down, and expand and contract with changes in humidity and temperature. As the wood moves so the drywall, fixed to the wood, moves with it.

Cracks in walls are a perfect example of this. Houses are always moving, even new builds. This could be due to settling, which you find with all new homes, movements in the soil under the house, or changing humidity levels (amongst other things). When this happens, cracks can appear in drywall, plaster or concrete. In most cases, these cracks are nothing to worry about. In others, however, they could be a sign of structural issues that need fixing quickly.

If the cracks are jagged, are at 45-degree angles or look like a flight of stairs going up your wall, you probably need to get them checked out. They are probably harmless but could be a sign of structural issues that will need addressing, so it is worth making sure.

Wall

Most of the cracks you see in walls will likely be paper thin and anything less than a 1/8” is usually nothing to be concerned about. Cracks wider than this are, again, a sign there could be something wrong structurally.

Where the crack is can also tell you how serious it is. For example, hairline cracks around windows shouldn’t cause problems. However, cracks along joints that connect upstairs ceilings and partition walls could be a sign there are problems with your roof truss, which could end up with walls coming away from ceilings. If you do see cracks in the ceiling, it’s a good idea to check for water leaks too, as these can lead to significant damage if not repaired.

Concrete walls

Whereas vertical lines in plaster or drywall aren’t much to worry about, they could be if your walls are made of concrete. This is because cracks that are vertical or diagonal in concrete could be a sign of issues with your foundation. One of the main things to look for here is whether the crack widens at any point. If you see this, or cracks that look like a staircase, this could mean your house is heaving (where the concrete slab your home is built on starts to rise above its foundation).

Another potential issue that you’ll need professional help with is horizontal cracks, which could mean your home hasn’t been designed correctly and that there has been a build-up of pressure behind the wall. The presence of water is also something that will need immediate attention as this can lead to further damage, even if the initial crack wasn’t that significant.
