Crack in wall
Photograph with a scale and date. New, widening or structural-looking cracks need professional assessment.
What to do first
- Check whether the issue is isolated or affects the whole home.
- Take photos and note any recent changes, work or weather.
- Stop DIY if the task involves regulated work, hidden services, height or a safety risk.
What could be behind it
- Normal shrinkage or finish movement
- Moisture/weather exposure
- Structural movement that needs assessment
These are common possibilities, not a diagnosis of your specific home.
When to stop doing it yourself
Stop if you are unsure of the cause, cannot isolate the system safely, need to open fixed electrical/gas equipment, work at height, disturb hidden building fabric, or the problem is getting worse.
