How to remove and prevent mold in a bedroom closet?« Back to Previous Page

Based on the symptoms you've described, this is a classic case of mold growth due to condensation, a very common issue in Dubai villas, especially following periods of high humidity. The outside wall is a thermal bridge, where the temperature difference between the air-conditioned interior and the hot, humid exterior causes moisture to condense, providing the perfect environment for mold.

For immediate cleaning, safety is paramount. Wear an N95 mask, gloves, and eye protection. For a small, surface-level infestation on a non-porous surface like painted drywall, you can carefully clean it with a solution of detergent and water. Avoid using bleach, as it does not kill the roots (hyphae) and only bleaches the surface, while the fumes can be dangerous in an enclosed space. After cleaning, the area must be thoroughly dried. However, if the mold has penetrated the wallboard or the affected area is larger than one square meter, professional remediation is strongly advised to prevent cross-contamination and ensure complete removal.

Prevention is the critical long-term solution. The root cause is excess moisture. First, improve air circulation inside the closet. Leave the doors ajar occasionally and ensure there is a small gap between the back wall and your clothing. A small battery-operated dehumidifier or silica gel desiccant bags can help control moisture in the enclosed space. Most importantly, address the thermal bridging on the external wall. This may require a professional assessment to evaluate the need for improved insulation or vapor barriers, which are essential for building integrity in the UAE climate.

Given that the mold is on a structural wall and has caused a persistent damp smell, I recommend a professional inspection. Our certified experts at Saniservice can conduct a thorough assessment using moisture meters and thermal imaging to identify the exact moisture source and extent of the problem, then execute a definitive remediation protocol.
