Could mold in our closet be causing our cough?« Back to Previous Page

Yes, mold in your closet is a very likely cause of the persistent coughing, especially in children. The black, fuzzy spots and damp smell confirm an active colony, which releases spores and microbial volatile organic compounds (mVOCs) into the air you breathe. These are potent irritants known to trigger allergy-like symptoms, including chronic coughing, congestion, and sore throats.

Your first step is to isolate the area. Immediately close the door to the under-stairs cupboard and, if possible, seal the gap at the bottom with a towel to prevent spores from circulating into your living space. Do not attempt to clean the moldy items yourself, as disturbing them will aerosolize a high concentration of spores. For a situation of this scale, with visible growth on multiple porous items like clothing, a professional inspection is strongly recommended.

In Dubai's climate, this is a common issue. Enclosed storage areas are prone to condensation due to high humidity meeting cooler interior surfaces, and year-round AC use can create hidden damp spots if drainage is faulty. A certified inspector can identify the moisture source—whether it's a plumbing leak, condensation, or external water seepage—and assess the full extent of the growth, which is often not limited to just the visible surface. They will perform air quality tests to quantify spore levels in your home and take swab samples for lab analysis to identify the mold species, which determines the appropriate remediation strategy. Addressing the root moisture problem is the only way to prevent it from returning. Until the inspection, keep the children out of the immediate area and consider using a standalone HEPA air purifier in an adjacent room to help reduce airborne irritants.
