Is black mold from AC leak a job for professionals?« Back to Previous Page

Based on your description of a recurring black mold colony stemming from an AC leak in Mirdif, this is unequivocally a job for professional mold remediation. The fact that it returned more aggressively after a DIY attempt with vinegar is a classic indicator of a deeper, unresolved issue.

Vinegar or bleach only addresses the surface discoloration, not the root cause. The leak has almost certainly saturated the wall cavity and potentially the insulation behind the wardrobe, creating a permanent reservoir of moisture. In Dubai's high-humidity climate, this hidden dampness, combined with condensation from your AC system, creates the perfect environment for rapid and resilient mold growth. The airborne spores from this colony are likely circulating through your AC system, contaminating other areas and posing potential health risks.

According to UAE health and safety guidelines, persistent mold growth exceeding 1 square meter and originating from a chronic water source requires professional assessment and remediation. A certified company like Saniservice will first conduct a thorough inspection, including moisture mapping and air quality testing, to determine the full extent of the contamination. The remediation process involves isolating the area, removing the affected porous materials (drywall, insulation), HEPA vacuuming, and applying professional-grade antimicrobial treatments to eliminate the spores at their source.

For a single room, the cost can vary significantly based on the extent of the damage behind the wall. For a contained issue, you might be looking at a range of AED 2,000 to AED 5,000, which includes inspection, containment, remediation, and a post-clearance test to ensure the environment is safe. Given the health risks and potential for structural damage, a professional solution is not just recommended but necessary. I strongly advise you to stop DIY efforts and call for a professional inspection. Contact Saniservice at 800-MOLDS (800-66537) or hello@saniservice.com for an accurate assessment and quotation.
