Tell us the building type, the rooms affected and whether the problem has interrupted normal use. Describe any known leak, staining, odour or recurring growth. Include the history of previous treatment and repairs where it is available. For a managed property, photographs and maintenance records can help connect observations made by different people over time.
It is also important to explain the purpose of the visit. Do you need an initial moisture assessment, a treatment proposal or written findings for a property manager? These are related but distinct requirements. Agreeing the scope early helps ensure that access, reporting and the proposed work match what the organisation needs, rather than producing a visit with an unclear outcome.
