Evidence of structural movement and subsidence within a property

Houses crack sometimes due to regular thermal and moisture changes in the structure and brickwork. However, if you see diagonal cracks that are wider at the top than at the bottom, it may be subsidence. The most common cause of subsidence is tree roots, which take water from the soil and cause it to dry and shrink. Other potential causes are a broken drain or prolonged dry weather. You should also do annual checks of your property to ensure there are no blockages.
