Black mold near AC in Dubai: DIY or professional help?« Back to Previous Page

A dinner plate-sized patch of black mold from an AC leak is a significant concern and typically requires professional assessment. The high humidity in Dubai, combined with condensation from a leaking unit, creates an ideal environment for mold to thrive inside wall cavities where you can't see it. While surface mold on non-porous tile can sometimes be cleaned with a bleach solution, porous materials like drywall and plaster absorb moisture, allowing mold to root deeply.

DIY cleaning with supermarket bleach often only bleaches the visible surface, leaving the root structure intact to regrow. It also fails to address the primary issue: the ongoing moisture from the AC leak. For a patch that large and in a hidden location, the underlying damage is likely more extensive.

In Dubai, reputable remediation follows international IICRC standards. The process involves isolating the area, removing contaminated porous materials, HEPA vacuuming, and applying EPA-approved antimicrobials. Crucially, they will identify and rectify the source of the moisture—in this case, your leaking AC unit—to prevent immediate recurrence. The cost for professional remediation is an investment in your indoor health and varies significantly based on the extent of the infestation behind the wall; you will need to request an on-site assessment for an accurate scope and quotation. For any visible mold over roughly one square foot, and especially when caused by an appliance leak, a professional inspection is strongly advised.
