Make each observation comparable
Choose a fixed reference such as the left edge of a doorway or the ceiling corner above a window. Describe the affected surface relative to it. If safe, take an overview from the same position each time, followed by a closer photograph. Keep the originals and label the date and room.
Record whether the surface looks unchanged, newly wet or different in extent. A photograph taken closer to the wall can make the same mark appear larger. Lighting and viewpoint should therefore be noted when images seem inconsistent.
Worked example: two photographs of one mark
Suppose the first picture shows a ceiling mark beside a light fitting and the second is a close-up of its edge. The images alone cannot establish that the mark spread. A better record says the viewpoints differ and describes any fresh droplets actually observed. A later overview from the original position may provide a more useful comparison, if it can be taken safely.
If water is near electrical equipment, do not approach it to improve the photograph. HSE's electrical-safety guidance supports competent assessment of unsafe equipment. Recording evidence must not delay the response to an active problem.
| Entry | Useful wording |
|---|---|
| Visible condition | Fresh droplets were seen at the doorway-side edge. |
| Photo limitation | The second image is closer and cannot show overall size reliably. |
| Uncertainty | The time wetting began is unknown; this is when it was noticed. |
Report changes that affect the enquiry
Include relevant ordinary events such as cleaning, normal fixture use or a repair, but keep their timing separate from a claim of causation. A mark noticed after a shower does not by itself identify a shower defect.
GOV.UK's damp guidance emphasises addressing the underlying cause. A dry-looking surface or a repainted stain should therefore be recorded as a change, rather than treated as proof that the source is resolved. Send the new observation with the earlier reference so the professional can understand the sequence.
