How to treat black mold in closet and inform landlord?« Back to Previous Page

The black spots in your closet corner are likely mold, a common issue in Dubai due to high humidity and condensation from year-round AC use. For a small area, you can treat it yourself by first scrubbing the surface with a mixture of white vinegar or a diluted bleach solution. Allow the area to dry completely, then use a dehumidifier or moisture absorber in the closet to prevent recurrence.

However, since the mold is on an exterior wall and the room feels persistently damp, the issue is likely a building envelope problem—possibly water intrusion or significant thermal bridging causing condensation. This is not something surface cleaning will fix permanently.

You should absolutely inform your landlord. Under typical Dubai rental regulations, structural and maintenance issues that affect the habitability of the property, such as water seepage leading to mold, are the landlord's responsibility. Document the issue with clear photos and send a written notification, requesting they investigate and repair the source of the moisture.

For peace of mind, a professional inspection can identify the exact moisture source and mold type. Companies with a microbiology lab can provide a precise identification, which is crucial for understanding any health risks and ensuring the remediation method is correct. Treating the symptom without fixing the underlying moisture problem will only lead to it returning.
