AC leaking and black mold in Dubai apartment?« Back to Previous Page

The black spots are likely Stachybotrys or Cladosporium, two mould types common in Dubai's high humidity when AC condensation isn't draining properly. This is a health concern and requires immediate action.

For safe cleaning, wear an N95 mask and gloves. Isolate the area and wipe the visible mould with a microfibre cloth dampened with a diluted white vinegar or hydrogen peroxide solution. Never use bleach, as it can worsen indoor air quality. Bag and dispose of the cloth immediately. This addresses surface growth only.

The root cause is the AC leak. You must call a certified HVAC technician to clear the clogged condensate drain line, the most common issue here. They should also check the drain pan and insulation. Without this fix, mould will return quickly.

Given the leak has affected the wall and carpet, a professional mould inspection is strongly advised. Hidden moisture inside the wall is likely, and improper cleaning can aerosolize spores. Reputable inspectors use moisture meters and thermal cameras to find the full extent, then provide a remediation protocol. In Dubai, look for companies with DHA-approved sanitisation certifications and their own microbiology lab, as they can identify the mould species and verify it's gone post-cleanup.

To prevent recurrence, ensure your AC unit is serviced every six months, especially before peak summer humidity. Keep the room well-ventilated when possible.
