Is toxic mold causing our family's illness?« Back to Previous Page

The black mold in your storage cupboard is likely contributing to the coughing and sinus issues, as these are common reactions to mold exposure. "Toxic black mold" specifically refers to Stachybotrys chartarum, which is less common than other black-colored molds like Aspergillus or Cladosporium. All of them can cause health effects, especially in enclosed spaces where spores become concentrated.

Given the UAE's high humidity, this scenario is unfortunately common. The under-stair cupboard is a classic problem area because it's enclosed, often lacks ventilation, and can trap moisture from temperature fluctuations with your year-round AC use. The damp, earthy smell confirms active microbial growth.

For your family's health, the immediate step is to isolate the area. Keep the door closed and avoid disturbing the mold, as this can release a large number of spores. Do not attempt to clean it yourself with bleach, as this can exacerbate the problem without addressing the root moisture source.

The only way to know the species and potential risk is through professional air and surface sampling, with the samples analyzed by an accredited microbiology lab. This identifies what you're dealing with. A proper remediation plan will then focus on fixing the underlying humidity issue—likely poor ventilation or a condensation leak—and safely removing the contaminated materials. In Dubai, look for providers certified by institutions like the IICRC, as they follow strict protocols to contain the area and prevent cross-contamination throughout your home during the cleanup process.
