Show the whole wall or opening before a close view of the affected surface. Say which room and side of the room it is, when you first noticed it and what changes. Photographs can help plan an enquiry, but they cannot establish concealed layers, the material’s current condition or every possible water route. Identify what cannot be seen safely.
For ordinary household work, a separate deep-cleaning enquiry has another scope. Mould should be described directly rather than assumed to be included because it appears in a room photograph.
