Black mold from AC leak: need professional removal in Dubai?« Back to Previous Page

Based on your description of a recurring black mold patch from an AC leak at Jumeirah Lakes Towers, this is absolutely a job for a professional remediation company. Your attempt with vinegar is a common mistake; it is not an effective biocide for porous materials like drywall and wallpaper. The mold's root system (hyphae) remains deep within the wall, and the moisture from the leak continues to feed it, causing the rapid and worse regrowth you've witnessed.

The primary concern here is two-fold. First, the ongoing water intrusion from the AC unit is creating a perfect habitat for mold, exacerbated by Dubai's high ambient humidity which promotes condensation. Second, the mold colony is likely already producing mycotoxins and spores that can contaminate the AC system itself, becoming an airborne health hazard throughout your apartment. This requires a systematic approach: first, a certified inspection to identify the exact mold species and the full extent of the contamination behind the wall using tools like moisture meters and borescopes. The source of the AC leak must be identified and repaired by an HVAC technician to prevent recurrence.

Remediation involves isolating the area with containment barriers, using HEPA filtration devices to capture airborne spores, safely removing the contaminated wallpaper and affected drywall, and then applying professional-grade antimicrobial agents to eradicate all traces. The cost for a professional job of this scale in Dubai can vary, but for a contained bedroom wall issue, you should expect a range from AED 2,500 to AED 6,000, depending on the extent of the damage and the required repairs.
