Whenever structural cracking and movement appear significant or significantly worsen, a qualified & licensed Structural Engineer should be consulted for further advice.

Cracks occur when forces either externally, internally within a building, or as a result of chemical changes within the building's materials are greater than it can withstand.

Cracking and movement can be structurally dangerous. Differential movement throughout a building may be a consequence of poor design, ageing or changing environmental conditions to which a rigid building cannot adapt without fracturing.

The form and positioning of cracking depends upon the building's weak points, particularly around doors and windows and where floor and roof connect to walls. Other factors are the size, shape, and position of the crack, the age of the crack indicating repetitive movement, and crack widening suggesting settlement or support failure.
