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

That leak is creating the perfect environment for mold—constant moisture and Dubai's high humidity are a powerful combination. The black spots are likely Cladosporium or Aspergillus, which are common here from AC condensation issues.

For a small patch (under one square foot), a DIY approach with a vinegar solution can be effective for surface cleaning. However, the critical issue is the water source. You must fix the AC leak first; otherwise, the mold will return within days, no matter how much you clean.

In your case, with water leaking into the wall cavity, professional remediation is strongly advised. The mold is likely growing inside the wall, which you cannot properly address yourself. DIY methods like bleach can actually aggravate the problem by adding moisture and only bleaching the surface color without killing the roots.

A reputable company will use containment procedures to prevent spores from spreading to other parts of your home during cleanup, employ HEPA filtration to remove them from the air, and, most importantly, identify and resolve the root cause of the AC leak. They should also provide before-and-after testing to verify the space is truly clean. Given Dubai's climate, this comprehensive approach is the only way to ensure it doesn't quickly come back.
