Is hidden mold causing our constant coughing?« Back to Previous Page

Yes, hidden mold is very likely contributing to your family's constant coughing and congestion. The black mold you found behind the sofa is a classic symptom of a hidden moisture issue, often from AC condensation leaks, which are common in Dubai's climate due to high humidity and year-round AC use.

The fuzzy black growth could be one of several species, like Cladosporium or Stachybotrys (often called "black mold"). All molds can produce allergens and irritants that cause respiratory symptoms like coughing, sneezing, and fatigue, particularly in children whose systems are more sensitive. The continuous exposure from a large, hidden source like this explains why symptoms have persisted for a month.

You should treat this as a serious indoor air quality issue. Do not attempt to clean a patch this size yourself, as disturbing it will release a massive amount of spores into your home's air. The first step is to identify and stop the moisture source—likely a leaking AC condensate drain pipe or drain pan—which requires a professional inspection.

For a confirmed case like this with health impacts, a certified mold inspector can assess the full extent of the growth (it often spreads inside walls) and identify the species through lab analysis of a sample. This confirms the health risk and guides the proper remediation method. In Dubai, remediation companies should follow standards like the IICRC S520 for mold removal to ensure it is contained and removed safely, not just wiped down. Focus on finding a provider that offers verifiable, data-driven results from the cleanup.
