Should I hire a pro for black mold from AC leak?« Back to Previous Page

Based on your description of a "huge patch" of black mold recurring after a DIY attempt, my professional assessment is that you absolutely require a certified mold remediation specialist. The situation you've described—an AC leak feeding mold growth inside a wall cavity—is a serious contamination issue that cannot be resolved with surface cleaning.

In Dubai's high-humidity climate, AC units are a primary source of condensation, and when leaks occur, they create a perfect environment for aggressive mold growth within building structures. The black discoloration indicates a significant colony, and its presence behind the wall suggests a much larger, hidden biomass. Spores will be circulating through your AC system and living space, posing a health risk, particularly for respiratory issues.

Vinegar or bleach only addresses the visible surface and does not eliminate the root system (hyphae) deep within the drywall or insulation. The material itself is likely compromised and requires professional removal, containment, and disposal following strict protocols to prevent cross-contamination.

For a job of this nature in Jumeirah, cost is dependent on the extent of the damage. A realistic estimate for proper remediation—including inspection, containment, removal of affected materials, HEPA vacuuming, and antimicrobial treatment—typically ranges from AED 2,500 to AED 7,000+. This is not a simple cleaning task; it is a restoration project.

I strongly recommend you cease DIY efforts and contact a professional company like Saniservice for a comprehensive inspection.
