What you can do
- Photograph the crack and the whole wall from a safe position, noting the date.
- Look without touching for loose material, a corresponding indoor crack or newly sticking doors.
- Tell the owner or manager before covering the evidence.
How to tell whether it helped
Painting a crack is not proof of safety. Repair should follow assessment of its cause; keep any requested monitoring record.
When to stop
Keep people clear of fast-changing cracks, falling pieces or distortion. Immediate danger needs emergency help; structural assessment needs the appropriate qualified specialist.
How NAPREMO can help
NAPREMO can help plan repairs after the cause is established. A repair enquiry does not replace a structural assessment.
