Black mold in closet causing coughs - who to call?« Back to Previous Page

Black mold in a closet against an exterior wall is a classic sign of condensation due to the temperature differential between the air-conditioned room and the humid outdoor air, a common issue in Dubai villas. For your children's coughs, the priority is safe removal to prevent spore dispersal.

Do not attempt to clean significant black mold yourself with bleach or other cleaners. This can aerosolize spores and worsen the problem. For a small patch (under one square foot), you can carefully wipe it with a detergent solution while wearing an N95 mask and gloves, ensuring the area is well-ventilated. However, given the location and the health symptoms, a professional assessment is strongly advised to identify the moisture source.

The root cause is almost always excess moisture. In your case, it could be a small plumbing leak within the wall, condensation from an AC duct, or inadequate insulation in the exterior wall. A proper mold inspection involves using moisture meters and thermal imaging cameras to pinpoint the hidden source of water intrusion that you cannot see.

For remediation, you should call a company that specializes in mold identification and removal, not a general handyman. Look for a provider that conducts pre- and post-remediation testing to verify the problem is solved. They will contain the area, safely remove the contaminated materials, treat the space, and most importantly, rectify the moisture issue to prevent recurrence. Without fixing the root cause, the mold will simply return.
