Is this dangerous mold and can I clean it myself?« Back to Previous Page

Based on your description, this is highly likely to be a case of active mold growth, and it should be treated as a potential health hazard. The black spots spreading from an AC leak are a classic indicator. The persistent moisture from the leak, combined with Dubai's high humidity and the organic material in wallboard, creates an ideal environment for mold. Your morning headaches are a common symptom of mold exposure, often resulting from mycotoxins and spores released into the air you breathe while sleeping.

Cleaning this yourself with bleach from ACE is strongly discouraged. Bleach is ineffective on porous surfaces like drywall; it only bleaches the surface color while leaving the root structure intact, allowing the mold to regrow quickly. More critically, improper cleaning can agitate the colony, causing a massive release of spores into your indoor air and significantly worsening the contamination and your health symptoms.

This is definitively a job for a professional mold remediation company. The process requires more than just wiping the surface. A certified inspector will conduct air and surface sampling to identify the mold species and spore concentration levels. Remediation involves containing the area with physical barriers and negative air pressure to prevent cross-contamination, safely removing the affected porous materials (the section of wall), HEPA vacuuming, and applying professional-grade antimicrobial agents. Finally, the source of the moisture—the AC leak—must be identified and repaired by an HVAC technician to prevent recurrence.

For a small, contained area like behind a wardrobe, a professional inspection and remediation could range from AED 1,500 to AED 3,500, depending on the extent of the damage behind the surface. Given your symptoms and the ongoing water issue, I recommend you cease using that AC unit and contact a professional immediately.
