What Causes Cracks in Walls?

Cracks in walls can appear for a variety of reasons, and while some are harmless, others may signal more serious structural issues. In many Swindon properties, cracks form as a result of ground movement, settlement, or ageing materials. Changes in moisture levels in the soil beneath the building can cause foundations to shift slightly, especially in areas with clay-rich ground. Other causes can include temperature changes, vibrations from nearby traffic or construction, or even poorly executed building work. Cracks often form around windows, doors, and corners, where the structure experiences more movement or stress. While hairline cracks in plaster can be purely decorative, larger or widening cracks in brickwork or render should always be checked by a professional. At ASRS Ltd, we carefully examine the cause and nature of the cracking to determine the best repair method. Our goal is always to provide lasting, practical solutions rather than temporary cosmetic fixes.

Our Approach to Crack Repairs

Every property is different, which is why we tailor our crack repair approach to suit each individual building. At ASRS Ltd, we start with a detailed inspection to understand the cause and extent of the cracking. If the damage is found to be structural, we look at the underlying reasons before recommending a repair strategy. For non-structural cracks, such as minor cosmetic issues in plaster or rendering, we may be able to carry out straightforward repairs with minimal disruption. Where structural integrity is a concern, we may use techniques such as crack stitching or wall reinforcement to stabilise the area and prevent future movement. Crack stitching involves installing stainless steel bars across the affected area, bonded into the wall to restore strength and distribute loads evenly. This is a proven method that provides a long-term fix for most masonry cracks. We always use the best materials and carry out repairs to the highest standard, ensuring a strong and discreet finish.

Common Types of Cracks and What They Mean

Understanding the type and location of a crack is important when deciding how serious it might be. In Swindon, we often see vertical and diagonal cracks forming around doors and windows, which can suggest some level of movement in the building. These cracks may be caused by seasonal ground movement, especially during periods of prolonged wet or dry weather. Horizontal cracks, particularly in external walls or near the base of a property, can be a sign of more serious issues such as foundation movement or wall tie failure. Step cracks in brickwork or bulging areas of a wall might suggest that structural elements are under strain or have shifted. While some cracking is common in older buildings as they settle over time, rapid changes or widening gaps should never be ignored. At ASRS Ltd, we use our knowledge of local construction methods and building materials to diagnose the cause accurately and provide the right solution for each type of crack.
