Black mold from AC leak: DIY or call a pro in Dubai?« Back to Previous Page

Based on the description of a "huge patch of black mold" caused by a prolonged AC leak, my professional recommendation is that you absolutely need to call a certified mold remediation company. This is not a safe or effective DIY project.

The combination of Dubai's high humidity and the constant moisture from an AC leak creates an ideal environment for aggressive mold growth. What you see on the surface of the drywall is only a fraction of the problem; the fungal roots (hyphae) will have deeply penetrated the porous material. Surface cleaning with bleach is ineffective as it does not kill the roots and can actually aggravate the spores, worsening airborne contamination. The "awful smell" is a strong indicator of a significant microbial volatile organic compound (MVOC) release, which is associated with poor indoor air quality and potential health risks.

UAE regulations and best practices for indoor environmental quality require that such infestations be handled by trained professionals. We use industrial-grade HEPA filtration units to contain and scrub the air, followed by the safe removal and disposal of contaminated porous materials like drywall. The underlying cause—the AC leak—must also be identified and repaired by a certified HVAC technician to prevent immediate recurrence.

For a situation of this severity, a professional inspection is non-negotiable. I strongly advise you to contact our team at Saniservice for a comprehensive assessment and remediation plan. You can reach us at 800-MOLDS (800-66537) or via email at hello@saniservice.com to schedule an inspection.
