Is black mold in my closet causing my symptoms?« Back to Previous Page

That black patch in your closet is very likely the cause of your symptoms. The timing of the mould growth and the onset of your persistent sore throat and congestion are strong indicators of a connection, as these are classic signs of mould exposure. The dampness on the outside wall suggests a condensation issue, which is common in Dubai due to the high humidity outside meeting the cold AC-cooled surfaces inside.

For your safety, avoid disturbing it. Do not try to wipe or spray it with bleach yourself, as this can aerosolize the spores and worsen your indoor air quality and symptoms. The first step is to address the moisture source. Move all items away from the wall, improve air circulation in the closet by leaving the door open, and use a dehumidifier or your AC to lower the room's humidity. Check if the outside wall has any visible cracks or leaks that need sealing.

For a patch that large and given your health reaction, a professional inspection is strongly recommended. They can identify the specific mould species through lab analysis to confirm the risk level and locate the exact moisture intrusion point, which is often not obvious. In Dubai, remediation must follow strict DHA and DM guidelines to ensure it's contained and removed safely, preventing spores from spreading to other parts of your home. Proper remediation involves containment, HEPA filtration, and antimicrobial treatment of the area, not just surface cleaning.
