How to quickly fix damp wall mold in closet?« Back to Previous Page

Mold on a damp exterior wall is a common issue in Dubai, primarily caused by thermal bridging. The intense outdoor heat transfers through the wall, cooling the interior surface below the dew point and causing condensation, which mold then feeds on.

For immediate action, wear a mask and gloves. Wipe the area with a solution of white vinegar or a diluted bleach mixture (1 part bleach to 4 parts water). Dry the surface thoroughly with a fan. Remove and wash any affected clothing. However, this only addresses the visible growth, not the underlying moisture.

The root cause is the condensation from the temperature differential. In many cases, improving air circulation in the closet by leaving doors ajar and using a small desiccant dehumidifier can help. For a more permanent solution, the wall may need to be assessed for insulation flaws.

You should absolutely notify your landlord. Under typical Dubai rental laws, structural issues like this, which are related to the building envelope, are the landlord's responsibility to investigate and remediate properly. A professional inspection, including moisture mapping, can identify the exact cause. Companies with their own microbiology labs can also test the mold to identify the species, which determines the appropriate remediation strategy, especially if the area is larger than one square meter. Simply painting over it will not solve the problem.
