Black mold in bedroom closet: DIY or building management?« Back to Previous Page

That black, fuzzy patch is a common issue in Dubai due to the high humidity and condensation on exterior walls. The dampness you feel is the core problem—the mold is just the symptom.

For a small patch (under one square foot), you can clean it yourself. Bleach is not recommended indoors; it can irritate your lungs and doesn't prevent regrowth. Instead, use a dedicated fungicidal cleaner or a solution of white vinegar and water. Scrub the area, let it dry completely, and address the moisture source by improving airflow in the closet and ensuring your AC is running efficiently to dehumidify the room.

However, since the mold is on an exterior wall and the area feels persistently damp, the issue is likely a building envelope problem, such as a small leak or inadequate insulation causing condensation. In this case, you should formally notify your building management. Dubai's Strata Law (Law No. 6 of 2019) typically holds the Owners' Association responsible for maintaining the common property and building structure, which includes external walls. They should investigate and repair the moisture intrusion from the outside.

If the patch is large, has a strong musty odor, or if anyone in the household has respiratory sensitivities, a professional inspection is wise. They can perform air and surface sampling to identify the mold species and confirm the moisture source, which provides documented evidence for your building management and ensures the remediation is handled correctly.
