Is black mold causing our coughs and how to clean safely?« Back to Previous Page

The recent humidity spike combined with year-round AC use creates the perfect environment for mold growth in Dubai villas. The black substance you found is likely a mold colony, and its spores being circulated by your AC system are a very probable cause of the persistent coughing, especially in children.

For a small patch (under one square foot), you can clean it yourself safely. Wear an N95 mask, nitrile gloves, and eye protection. Isolate the area by closing the door and opening a window if possible. Scrub the area with a solution of detergent and water. Avoid bleach; it only removes the color and doesn't kill the root structure. Dry the area completely immediately after cleaning with a fan. However, since the mold is behind furniture and your AC is actively spreading spores, the visible patch is likely just a small part of a larger problem inside your walls or AC unit.

Given the symptoms in your children and the hidden nature of the growth, a professional inspection is strongly advised. They use moisture meters and borescopes to find the full extent of the problem, which is critical for a complete solution. DIY cleaning often addresses only the surface, leaving the root cause intact.

For verification, a lab test is the only way to confirm the mold type and its potential health risks. In Dubai, remediation companies should follow DHA guidelines and provide documented proof of clearance testing after the cleanup is complete, ensuring the environment is safe for your family.
