Can I treat AC mold myself or need a pro in Dubai?« Back to Previous Page

Based on the symptoms you've described – persistent AC leakage leading to widespread black spots on the wall – this is a serious moisture intrusion issue that requires professional assessment and remediation, not a DIY fix.

The black spots are almost certainly active mold growth, fueled by the constant moisture from the leaking AC unit and exacerbated by Dubai's high ambient humidity. Using bleach is strongly discouraged. It is ineffective on porous surfaces like drywall, as it only bleaches the surface color without killing the root system. More critically, it can agitate the spores, increasing airborne contamination, and the high water content can actually provide more moisture for the mold to feed on.

In the UAE, proper mold remediation is governed by strict hygiene and environmental standards. A certified professional will first conduct a comprehensive inspection, including moisture mapping and possibly air quality testing, to determine the full extent of the contamination, which is often far greater than what is visible. The process involves isolating the area with containment barriers, using HEPA filtration to capture airborne spores, safely removing and disposing of contaminated porous materials (like the affected drywall section), and applying EPA-approved, specialized biocides to eliminate the mold at its source.

For a small bedroom in Dubai, the cost for professional inspection and remediation can typically range from AED 1,500 to AED 4,000, depending on the severity and the extent of the damage behind the wardrobe. Given the AC is the source, an HVAC hygienization service is also highly recommended to prevent immediate recurrence.
