How to inspect AC leak and black mold in Dubai apartment?« Back to Previous Page

A professional inspection is the correct next step, as the issue is likely behind the wall. The source of the moisture—your AC leak—must be fixed first; otherwise, any cleaning is temporary. In Dubai's high humidity, mold can regrow on a damp surface within 24-48 hours, which is why the bleach wipe was ineffective.

A proper inspection involves three parts. First, the AC unit and drainage line must be examined to locate and repair the leak. Second, a moisture meter is used on the wall and carpet to map the full extent of the water damage, which is almost always larger than the visible stain. Finally, to identify the type of mold and its concentration, a surface or air sample should be collected for lab analysis. This step is crucial, as it determines the necessary scope of remediation, especially since the growth is inside a wall cavity.

For a Downtown apartment, you must notify your building management about the AC leak, as it may originate from a central chilled water system, which is their responsibility to repair. The inspection and any subsequent remediation should be conducted by a company that provides documented evidence of the contamination and the results of the cleanup, not just a visual assessment. This verifiable data is your assurance the problem is fully resolved.
