Mold from AC leak: DIY fix or professional in Dubai?« Back to Previous Page

Stop using the AC unit immediately to prevent further moisture from feeding the mold. What you're describing—a fuzzy black patch from a persistent leak—is a serious concern that requires professional assessment, not a DIY bleach solution. Bleach only removes surface discoloration on non-porous materials and is ineffective on porous surfaces like drywall; it also fails to address the root moisture problem and can push spores deeper into the area.

In Dubai's high humidity, an active AC leak creates a perfect environment for mold proliferation, which is likely exacerbating your wife's allergies. The remediation process requires isolating the area, safely removing and disposing of contaminated porous materials like the affected wall section, HEPA-vacuuming, and then addressing the original AC leak to prevent immediate recurrence. This is not a surface-level cleaning task.

For a standard apartment in JVC, the cost for professional remediation of a small, contained area is generally considered a minor project. The final price is driven more by the extent of the leak repair needed (e.g., fixing a drain pan vs. a refrigerant line) and the lab confirmation of the mold type than the square footage of the visible stain. Always request a company that provides before-and-after lab reports to verify the spore count has been returned to safe levels, as this is your only proof of a successful remediation.
