Wall cracks are common findings during property inspections. Their appearance can provide useful information, but a visual inspection alone may not establish their cause. Inspectors should focus on accurate observation, systematic documentation and appropriate recommendations.
1. Locate the crack
Record the room, wall position and nearby features such as windows, doors, columns or ceiling junctions. Consistent location references make it easier for contractors to find the defect.
2. Observe the crack’s appearance
Describe whether the crack appears vertical, horizontal, diagonal, branched or irregular. Record visible characteristics without assuming that a particular pattern proves a specific cause.
3. Record dimensions where appropriate
Estimate or measure the visible length and width using suitable tools. State whether dimensions are approximate and avoid implying engineering precision when the measurement method does not support it.
4. Photograph the crack clearly
Take a contextual photograph showing its position and a closer photograph showing the crack itself. Include a scale reference when useful and practical.
5. Check the surrounding area
Observe nearby paint, plaster, tiles, doors and windows for related visible findings. Record each distinct defect separately when doing so improves clarity.
6. Identify when further assessment is appropriate
Recommend further assessment when cracks are extensive, changing, associated with other concerning signs or otherwise outside the inspector’s competence to evaluate.
Do not declare a crack structurally safe or dangerous solely from a photograph or superficial observation.
Frequently asked questions
Are hairline cracks always harmless?
Not necessarily. Their significance depends on context, location, material and other evidence.
Should inspectors measure every crack?
Measurements are useful when they support clear documentation, comparison or follow-up. Apply a consistent company procedure.
Can a crack photograph establish its cause?
Usually not. Photographs document visible evidence, but determining the cause may require additional investigation.
Conclusion
Accurate crack documentation provides a useful record for rectification and follow-up. Record the location, appearance, measurements where appropriate and supporting photographs, while distinguishing observation from diagnosis.
