Say where droplets or wetness appear, approximately when you notice them and whether growth returns in the same location. Mention an existing fan, vent or window arrangement without assuming it works adequately. Include a whole-room view and a close surface picture. The enquiry should describe observations, care already attempted and known repairs rather than diagnose the property from one feature.
Ordinary dusting or room cleaning can be requested through regular domestic cleaning. That scope is different from investigating moisture and treating mould; a routine visit should not stand in for this enquiry.
