AC leak causing black mold in Jumeirah Village Circle?« Back to Previous Page

Based on your description, this is absolutely a job for a professional mold remediation company. The situation you've described—an AC unit leaking into a wall cavity and causing recurring black mold—is a serious concern that requires expert intervention, especially in Dubai's climate.

The continuous high humidity and condensation from a faulty AC unit creates a perfect breeding ground for mold. The fact that the musty odor returns when the AC operates is a major red flag; it indicates that the mold colony is active and likely spreading within the wall, a area you cannot access or treat with surface cleaning. Vinegar or DIY solutions are completely inadequate here, as they only address the surface visible to you, not the root cause or the hidden infestation.

In the UAE, proper remediation involves a multi-step process: first, a certified inspection to identify the moisture source and the full extent of contamination, often using tools like moisture meters and borescopes. Then, the remediation includes isolating the area, removing contaminated porous materials (like drywall), HEPA vacuuming, anti-microbial treatment of the structure, and finally, repairing the AC leak and the wall. The cost for a job like this can vary significantly based on the extent of the damage, but for a localized wall patch due to an AC leak, you could be looking at a range from AED 1,500 to AED 4,500. This typically includes the inspection, containment, removal, treatment, and ensuring the moisture source is resolved.

Given the health risks associated with black mold and the potential for structural damage, I strongly recommend you stop using that AC unit and contact a professional immediately.
