Urgent: mold in Dubai villa making family sick—what to do?« Back to Previous Page

First, isolate the storage room and close its AC vent to prevent spores from circulating. The black spots on the wall and clothes indicate active growth, which is a serious concern in Dubai's humid climate where AC systems can spread contaminants.

You need a professional indoor environmental assessor to conduct air and surface sampling. This is not a standard AC cleaning; it requires specialized equipment to test the air for spore counts inside the room, in the main living area, and at an outdoor control point. The lab analysis will identify the mold type (e.g., Cladosporium, which is common here, or more problematic types like Stachybotrys) and the concentration levels, which is critical data for any remediation plan.

Do not attempt to clean this yourself. Disturbing the mold without proper containment will aerosolize a massive amount of spores. Remediation involves setting up negative air pressure containment, HEPA filtration, removing contaminated porous materials like those sweaters, and professionally cleaning the wall structure. The entire process must be verified by post-remediation testing to ensure spore counts inside the villa are lower than those outside.

For immediate next steps, contact a company with certified mold remediators and their own microbiology lab to expedite the process from inspection to verification. This is a health priority, especially with children presenting respiratory symptoms.
