Mold in closet causing cough: DIY or professional removal?« Back to Previous Page

Black mold in humid climates like Dubai is a legitimate health concern, especially for children with asthma. The high humidity and condensation from year-round AC use create ideal conditions for mold growth in closets and behind walls.

For a small patch under 1 square meter, DIY removal can be attempted. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a mixture of detergent and water, then dry it completely. Discard any moldy porous items like cardboard boxes or fabrics. However, this only addresses visible growth; hidden mold in the wall or AC system could be the actual source of the spores causing the coughing.

Given the persistent symptoms and asthma history, a professional inspection is strongly recommended. DIY cleaning often fails to address the root moisture problem or remove all spores. Professionals use moisture meters and thermal imaging to find hidden dampness and perform air and surface sampling to identify the mold species and spore count. This diagnostic approach is critical in the UAE to ensure the AC system isn't spreading contaminants throughout the home.

For health safety and to prevent recurrence, the most effective strategy is to identify and fix the moisture source—often condensation or a minor leak—before any remediation.
