How to permanently remove closet mold and prevent recurrence?« Back to Previous Page

Closet mold on an outer wall with damp smells and condensation on windows points to high humidity and a potential thermal bridge or condensation issue, which is common in Dubai's climate. The immediate priority is removing the moldy items for cleaning or disposal to prevent spore dispersal.

For the mold itself, scrubbing visible growth with a detergent solution can remove it, but this only addresses the surface. The underlying cause is almost always excess moisture. Given the location on an outer wall, this could be due to condensation from the temperature difference between the air-conditioned room and the hot, humid outside air, or possibly a minor leak in the building envelope.

To prevent recurrence, you must control the humidity. Consistently running your AC helps, as it dehumidifies. For a closet, improve airflow by not overpacking it and leaving the door ajar. A disposable dehumidifier pouch or a small desiccant canister inside can help absorb excess moisture. For a more permanent solution, a professional assessment can identify if the wall requires insulation to prevent condensation (a thermal break) or if there's a hidden leak.

You should notify building management first, especially as it involves an external wall. They are responsible for the building envelope and may need to address external sealing or insulation. If the problem persists after their intervention, or if the mold covers a large area (more than one square meter), a professional inspection is recommended to identify the exact moisture source and species of mold, as some types require specific remediation protocols.
