Is this mold causing our persistent cough and allergies?« Back to Previous Page

Persistent coughs and allergies worsening over a month, especially in children, are classic indicators of a mold-related indoor air quality issue. Given the black spots spreading behind your wardrobe, it is highly probable that mold is a significant contributing factor.

The Dubai climate creates ideal conditions for this. High humidity, combined with the constant use of air conditioning, leads to condensation in hidden areas—particularly behind large furniture placed against exterior walls. This creates a damp microenvironment where mold spores, which are always present in the air, can rapidly colonize. The wall behind a wardrobe is one of the most common places we find hidden mold growth in villas.

While visual confirmation is a strong sign, the specific type of mold matters for health impact. Some species, like certain aspergillus molds common here, are more allergenic and can cause the exact respiratory symptoms you describe. The only way to confirm the type and its concentration in your air is through professional inspection that includes air and surface sampling, with analysis by an accredited microbiology lab. This data is crucial to understand the scope of the problem and plan an effective remediation.

For your situation in Jumeirah, a proper inspection should involve a thorough visual assessment of moisture-prone areas (like behind all wardrobes, under sinks, and in AC drip pans) and the use of calibrated equipment to measure humidity levels inside the walls. The inspector should then take air samples from both indoors and outdoors to compare spore counts, as well as tape or swab samples of the visible growth for species identification.

Any reputable company you contact should be able to explain this process clearly and be transparent about providing you with a detailed lab report. This evidence-based approach is what separates a legitimate diagnosis from a simple visual guess and will definitively tell you if this mold is the source of your family's illness.
