Damp and mould in rented homes: investigate the cause and follow up

Why a useful response needs an assessment, clear repair actions and a follow-up check rather than blame or a coat of paint.

A damp or mould report should lead to an investigation of the home and a clear plan for action. A photograph may show where the problem is visible, but it cannot establish every underlying cause. Repainting the area without understanding why it became damp can leave the original issue unresolved.

Take the report seriously

Record the affected rooms, when the problem was noticed and whether it has returned after earlier work. Give the tenant a clear contact and explain how the report will be assessed. Where there is an immediate safety or health concern, seek appropriate professional help promptly rather than waiting for a routine review.

Investigate the building

The government’s guidance for housing providers in England identifies building deficiencies, ventilation, heating and energy efficiency as relevant issues. It rejects blaming normal domestic activities as a substitute for addressing the causes. A competent assessment should consider the circumstances of the actual home, including leaks or defects that may not be visible from the surface mark.

Set out the work

Keep the assessment, recommended repairs and responsibilities together. Explain what will happen, who will arrange access and how the tenant will receive updates. If a contractor recommends further investigation, record that as an outstanding action rather than treating the visit as completion. Avoid a promise that a single product will solve every situation.

Work with the occupants

Provide practical information appropriate to the equipment and conditions in the home. Listen when a tenant explains that a control does not work or a room cannot be heated adequately. Advice about everyday use should sit alongside necessary building work, not replace it. Keep the conversation focused on resolving the problem.

Check whether it worked

Follow up after the intervention and ask whether the symptoms remain or recur. Retain the maintenance history so another report is not treated as an unrelated incident. This editorial guide concerns the response process in England; it does not diagnose mould, provide medical advice or set a universal legal deadline. Check the duties and time limits applying to the particular housing provider and tenancy. Reviewed 30 October 2026.
