Black mold in bedroom: DIY or call Dubai Marina management?« Back to Previous Page

That black patch behind your shoes is a classic sign of condensation buildup on a cold external wall, a very common issue in Dubai Marina apartments due to the high humidity and constant air conditioning. Your first step is to call your building management immediately. Under Dubai regulations, the building owner is responsible for the structure's integrity, including addressing moisture seepage or insulation failures that cause this problem.

While you wait for them to act, move all items away from the wall to improve air circulation. Wipe the visible mold off with a microfiber cloth dampened with a diluted detergent solution; never use bleach as it can worsen the problem. However, this only addresses the surface. The wall likely has moisture trapped inside, and the mold you see is just the fruiting body of a larger colony.

A professional inspection is strongly recommended here. The constant damp feeling indicates a persistent moisture source, which could be anything from a minor thermal bridge to a hidden plumbing leak. An expert can use moisture meters and thermal imaging to find the exact cause. If the patch is larger than one square meter, or if anyone in the household has respiratory sensitivities, a lab test to identify the mold species is wise to understand the potential risk. Simply cleaning it without fixing the underlying moisture issue will guarantee its return.
