These aren’t usually anything to worry about, however a crack at the top of a door frame, or one that extends diagonally from the corner of a door is slightly more serious. This is usually because a window compromises the strength of the wall slightly, causing cracks to appear. You should look at how long and deep the crack is, and call out a structural engineer who might be able to advise you on the seriousness of the issue.Ĭracks will generally appear in the weakest areas of the wall, such as around a window frame. Jagged cracks that move in a diagonal direction or look like a set of stairs moving up your wall could be a sign of structural movement and may be slightly more serious than cracks that simply run up and down.

A damaged wall would be considered severe when it’s 25 millimeters or wider (2.5 centimeters or one inch) as it could be a sign of structural damage, subsidence (the sudden sinking of a house and its foundations) or something else.

Hairline cracks of less than one millimetre in width or slight cracks of between one and five millimetres are generally not a cause for concern. Smaller cracks are generally nothing to worry about, however wider cracks, ones that run over doorways or those that run diagonally instead of vertically may be signs that something more serious is happening. When should you worry about cracks in walls? Some cracks can be longer and deeper than others, but when should a crack start to worry you? Read on to find out.
