Mold behind wardrobe: clean myself or call a pro?« Back to Previous Page

That black substance behind the wardrobe is a serious concern, especially with the kids coughing. The damp wall suggests a persistent moisture source, likely condensation from the AC unit's cold surface or a slow leak in the pipework inside the wall.

In Dubai's climate, this is a common issue. The high humidity combined with year-round AC use creates perfect conditions for mould when cold interior walls meet warm, moist air. Bleach is not recommended—it only removes surface discoloration and can worsen the problem by adding moisture. More critically, it doesn't address the root cause: the hidden moisture.

Because the wall is damp and you have health symptoms, a professional inspection is strongly advised. The visible mould is likely just the tip of the iceberg; the main colony is probably inside the wall cavity. A proper assessment will identify the exact moisture source (like a leaking AC condensate drain pipe) and the extent of the infestation. They can then perform remediation that controls spores and addresses the water issue, which is the only way to prevent it from returning. For health safety, it's best to have the area tested to identify the mould species.
