Is black mold causing our constant coughs and allergies?« Back to Previous Page

Black mold is a strong contender for causing your family's persistent coughs and allergy symptoms, especially given the size of the patch you described. The constant coughing is a common reaction to inhaling mold spores, which act as a powerful irritant to the respiratory system. In Dubai's climate, where we rely on year-round AC, hidden condensation leaks behind units or furniture create the perfect damp, dark environment for mold to thrive unnoticed.

For a patch of significant size, professional remediation is the safest course of action. Disturbing it yourself risks aerosolizing a high concentration of spores throughout your home's air, potentially making the problem much worse. In the UAE, look for a provider that follows IICRC S520 standards for mold remediation. The critical steps they should take include: first isolating the contaminated area with physical barriers and negative air pressure to prevent spore spread, then safely removing and bagging the moldy materials. The underlying cause, likely the AC condensate leak, must be identified and repaired by an HVAC technician to prevent immediate recurrence.

Before any cleaning, a professional inspection can confirm the mold type and extent. While often referred to generally as "black mold," several species can appear black; a lab analysis from a sample will identify it precisely. After remediation, ask for verification that the spore count in the air has returned to normal levels, which provides concrete evidence the problem has been resolved. For ongoing prevention, ensure your AC units are serviced regularly to prevent drain line clogs and maintain a humidity level indoors below 60%, using a dehumidifier if necessary.
