Is hidden mold causing our family's persistent cough?« Back to Previous Page

Yes, hidden mold is a very likely cause of your family's persistent cough and fatigue, especially given the climate in Dubai. The high humidity and constant use of air conditioning create ideal conditions for mold growth, particularly in hidden areas with a moisture source like your slow leak. The black, fuzzy patch you found is a significant indicator.

The persistent respiratory symptoms you describe—coughing, congestion, and unusual tiredness—are commonly reported in households with mold exposure. These occur because mold releases microscopic spores and microbial compounds into the air you breathe, which irritate the respiratory system. Children are often more susceptible to these effects.

Do not attempt to clean this yourself. Disturbing a large patch releases a massive amount of spores, which can spread the contamination throughout your home and exacerbate health issues. The safest approach is a professional inspection and remediation. In the UAE, look for a company that follows IICRC S520 standards for mold remediation. They will contain the area, safely remove the contaminated materials, and use HEPA filtration to clean the air. Crucially, they must also identify and fix the underlying moisture source—in your case, the leak—to prevent it from returning. For a case this serious, a post-remediation verification test from an independent lab is the only way to confirm the space is truly safe again.
