Black mold on dry wall in Dubai? What to do?« Back to Previous Page

Black mold on a drywall interior wall is a common issue in Dubai, even if the room doesn't feel damp. The constant AC use creates significant temperature differences between the cooled room and the unconditioned space inside the wall cavity. This leads to condensation forming on the cooler inner surface of the exterior wall, providing the hidden moisture mold needs to grow behind furniture like wardrobes.

Your first step should be to alert your building's maintenance team. They are responsible for the building envelope and need to investigate if there is a leak from pipes running inside the wall or a crack in the external facade allowing humidity to seep in. Do not attempt to clean it yourself with bleach, as this can agitate spores and only bleaches the surface, leaving the root colony intact.

For a spreading patch, a professional inspection is recommended to assess the extent behind the wall and identify the mold species. In Dubai's climate, remediation involves more than just wiping it down; the affected drywall often needs to be cut out and replaced to prevent recurrence, and a dedicated drying process is used to ensure all residual moisture is eliminated. A reputable inspector will use lab analysis to confirm the type and provide a protocol for safe removal.
