Urgent to remove mold for child's cough?« Back to Previous Page

Yes, this is urgent. A persistent cough in children linked to visible mould growth, especially on an exterior wall, requires immediate action. The recent high humidity has created ideal conditions for mould that may not have been active before.

The black patches are a sign of a moisture issue within the wall cavity, likely from condensation due to the temperature difference between your air-conditioned room and the hot exterior. This type of hidden moisture often supports more extensive mould growth than what is visible. The continuous cough is a common reaction to mould spores becoming airborne and being inhaled.

For your children's health, I recommend a professional inspection. They will use moisture meters and borescopes to assess the wall's internal condition and identify the moisture source. Proper remediation involves containing the area, removing affected materials, and using HEPA filtration to capture spores—not just wiping the surface, which can make the problem worse by dispersing spores.

Until a professional can assess, keep the children out of the room if possible and increase ventilation by running exhaust fans. Do not attempt to disturb the mould yourself by scrubbing it.

In Dubai, remediation should follow standards like the IICRC S520 to ensure it's done correctly and prevents recurrence. A reputable provider can also perform air quality testing after remediation to confirm the spore count has returned to a safe level.
