Black mold from AC leak: DIY or professional help?« Back to Previous Page

Based on your description, this is a serious situation that requires professional intervention. The black mold patch behind the wardrobe is a visible sign of a much larger problem. The leak from your AC has saturated the carpet, underlay, and likely the subflooring, creating a massive reservoir of moisture that mold is actively feeding on. The fact that it returned after a surface cleaning with vinegar confirms the infestation is deep within the building materials.

In Dubai's high-humidity climate, AC systems are a constant source of condensation. A leak provides the perfect breeding ground for mold, and the spores can easily become airborne and circulate throughout your apartment, potentially affecting air quality and health. DIY methods like bleach are strongly discouraged. Bleach is ineffective on porous materials, its fumes are hazardous in enclosed spaces, and it can actually aggravate the problem by adding more moisture.

A professional remediation company like Saniservice is essential. We would 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 and properly disposing of unsalvageable materials (carpet, underlay), HEPA vacuuming, abrasive cleaning of surfaces, and applying EPA-approved antimicrobial solutions. Finally, we identify and rectify the source—the AC leak—to prevent recurrence.

For a single room of this nature in a Marina apartment, you can expect costs to start from AED 2,500, depending on the severity and materials affected. This investment ensures the problem is solved correctly, safeguarding your property and health.
