Identify painted plaster, tile joints, a flexible seal or another finish rather than only naming the room. Explain softness, peeling or changes after earlier repairs without removing material to inspect it yourself. A wide view shows how the parts meet; a detail shows the visible condition. Say which layers remain hidden so the enquiry does not overstate what photographs establish.
An ordinary home deep clean has a different purpose. Mould and material deterioration should be reported separately rather than assumed to be stronger versions of normal room dirt.
