Black mold from AC leak: call pro and cost?« Back to Previous Page

Based on the scenario you've described in Jumeirah, this is a serious situation that requires immediate professional intervention. A slow AC leak inside a wall cavity is a significant concern, as it creates a perfect, hidden environment for mold growth, particularly the toxic black mold (Stachybotrys chartarum) you've identified. The strong smell indicates a large, established colony.

For this level of contamination, a DIY approach is not only ineffective but also hazardous. Disturbing the mold without proper containment can aerosolize spores, spreading the contamination throughout your apartment and posing serious health risks, including respiratory issues and allergic reactions. Furthermore, Dubai's high humidity and year-round AC use mean that if the moisture source isn't professionally identified and remediated, the mold will return quickly.

The process must begin with a comprehensive inspection, which includes moisture mapping and air quality testing to determine the full extent of the contamination behind the wall. Remediation involves setting up critical containment barriers and negative air pressure to prevent cross-contamination, the safe removal of affected drywall and insulation, professional-grade antimicrobial treatment of the cavity, and finally, HEPA vacuuming and air scrubbing. The leak itself must be repaired by a certified AC technician.

Costs in the UAE for a project like this are highly variable but significant. For a contained wall leak with hidden damage, you should expect a professional inspection and testing to start from AED 1,500 - 2,500. The full remediation process, including demolition, disposal, and restoration, can range from AED 8,000 to AED 20,000 or more, depending on the square footage affected and the complexity of the access. This is a justified investment in your health and property.
