How to treat black mold and prevent recurrence?« Back to Previous Page

Black mold behind furniture on an exterior wall is a common issue in Dubai due to the high humidity and constant air conditioning creating cold surfaces where condensation forms. The wall is likely a thermal bridge, where outdoor heat meets indoor AC, causing moisture to trap and mold to grow unseen.

For a small patch (under one square meter), you can treat it yourself. Wear an N95 mask and gloves. Scrub the area with a mixture of water and detergent or a dedicated mold removal product. Dry the wall completely immediately after. Do not just paint over it, as the mold will bleed through.

To prevent recurrence, you must control the moisture. The core issue is the lack of air circulation behind the wardrobe. Move the furniture at least two inches away from the wall to allow air to flow. A dehumidifier in the room can help, but addressing the condensation point is key. Consider insulating that specific wall to reduce the temperature difference that causes condensation.

Given the symptoms you describe, a professional inspection is strongly recommended. DIY cleaning only addresses surface mold; hidden growth inside the wall cavity is a possibility. An inspector can use a borescope to check inside the wall and perform air quality testing to identify if the mold type is contributing to the coughing. This is the only way to be certain the environment is safe for your children.
