Is black mold causing health issues and how to clean?« Back to Previous Page

The damp wall and black patch are a clear indicator of a moisture issue, and the symptoms you describe are consistent with prolonged mold exposure. In Dubai's climate, this is often caused by a combination of high external humidity and a thermal bridge—the cold wall behind the wardrobe meeting warm, humid room air, causing condensation the AC can't manage. This persistent dampness allows mold to thrive.

For a patch smaller than one square meter, you can clean it yourself. First, wear an N95 mask, gloves, and eye protection. Never dry-brush it, as that releases spores. Scrub the area with a solution of detergent and water, then wipe with a diluted bleach solution (one part bleach to ten parts water) to disinfect. Dry the surface completely with a fan. The critical step is fixing the moisture source; improve air circulation behind the wardrobe and consider a dehumidifier for that room.

Given the duration of symptoms and the wall's dampness, the mold growth inside the wall cavity is likely more extensive than what's visible. Self-cleaning only addresses the surface, not the root cause. A professional inspection with a borescope can assess the wall's interior and the extent of the problem. This is particularly advised in older Deira buildings where hidden condensation issues are common. Remediation for these cases involves controlled removal to prevent cross-contamination.
