Black mold behind wardrobe in Dubai: what to do?« Back to Previous Page

Your situation is common in Dubai due to the high humidity and condensation that builds up on cold walls, especially behind furniture blocking airflow. The black spots are very likely mold, a frequent cause of the respiratory irritation and persistent cough you're describing.

Stop using the room's AC immediately to prevent it from distributing spores. Do not attempt to clean it with bleach, as this can aggravate the situation. The fastest way to get a definitive answer is through professional mold inspection. A certified inspector will conduct air and surface sampling, which is then cultured in a microbiology lab to identify the exact species and concentration. This is crucial, as not all black molds are the highly toxic Stachybotrys, but many common types can still cause significant health issues, particularly for children. The lab report will dictate the necessary remediation scope.

For remediation, look for a company that follows IICRC S520 standards, the global benchmark for mold removal. They will set up containment with negative air pressure to prevent cross-contamination, safely remove the affected materials, and use HEPA filtration to clean the air. The final step should always be post-remediation verification (PRV)—a separate lab test to confirm spore counts have returned to safe, outdoor levels. This documented proof is your assurance the problem is resolved.

To prevent recurrence, ensure the wall is properly sealed and consider using a dehumidifier alongside your AC, as ACs alone often don't control humidity sufficiently in our climate. Keep furniture at least a few inches away from walls to allow for air circulation.
