Black mold in bedroom corner - call management or clean myself?« Back to Previous Page

This situation is very common in Dubai due to high humidity and condensation forming on cold surfaces like exterior walls and ceilings. The first step is to assess the extent. If the area is smaller than a square meter and confined to the surface, you may handle it yourself. For anything larger, or if there's a musty smell or visible moisture, a professional inspection is strongly advised to identify the moisture source.

You should absolutely inform your building management, especially if this is an external wall. They are responsible for the building envelope, and the leak or condensation source may be originating from a common area, a faulty external seal, or a rooftop issue. They need to be made aware to prevent recurrence after any cleaning.

For a small area, you can clean it with a solution of diluted white vinegar or a dedicated mold remover, wearing an N95 mask and gloves. However, this only addresses the visible growth, not the underlying moisture problem. In many cases, the hidden condensation within the wall cavity requires professional-grade drying equipment.

Given that it's behind a wardrobe, the lack of air circulation has exacerbated the issue. After remediation, ensure the area is well-ventilated and consider using a dehumidifier, especially during the more humid months, to prevent it from returning. A professional assessment can pinpoint the exact cause—often a thermal bridge in the construction or a minor leak—which is crucial for a permanent solution.
