Mould and moisture: investigate the cause before covering the mark

Use these steps to plan, check and keep a record of your next actions.

• Record visible dampness or mould and when it appeared without disturbing suspect materials.
• Investigate and stop the moisture source.
• Arrange assessment of hidden extent and older-material hazards where appropriate.
• Ask how containment, drying and cleanup will be verified.
• Keep repair evidence and watch for recurrence.
