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

Stop using the AC and address the leak immediately. A leak inside the wall cavity means moisture is spreading unseen, and black mold growth indicates a persistent problem. In Dubai's climate, this will only worsen due to high humidity.

For a concealed leak and visible mold growth, DIY is not advisable. Bleach only removes surface discoloration on non-porous materials; it cannot penetrate drywall to kill the root structure of the mold, and the moisture problem remains. Disturbing it incorrectly can aerosolize spores throughout your apartment.

This requires professional remediation. The process involves identifying and repairing the AC leak, isolating the contaminated area, safely removing and disposing of affected drywall and insulation, HEPA vacuuming, and antimicrobial treatment of the cavity. The cost is not for a simple cleaning but for the demolition, repair, and restoration work. For a single interior wall, the investment is typically proportionate to the size of the affected area and the extent of the water damage.

Request a detailed assessment from a company that provides documented before-and-after testing from an independent lab. This verifies the mold has been properly addressed and the humidity levels normalized, preventing recurrence.
