Mold under AC leak in Dubai: call maintenance or remediation?« Back to Previous Page

A slow leak from an AC unit in Dubai's climate is a significant source of moisture, and the resulting mold growth is a health concern that requires immediate action. The combination of high ambient humidity and a constant moisture source from the leak creates an ideal environment for mold, which can cause irritation and worsen allergies.

You should call your building maintenance first. Their responsibility is to stop the leak at its source, which is the primary step. However, building maintenance teams are typically not equipped for proper mold assessment or remediation. Their solution will likely be to fix the AC drain line and perhaps wipe the visible mold away with a disinfectant, which addresses only the surface and not the root problem.

The mold you see is likely just the surface manifestation; the moisture has almost certainly wicked into the carpet underlay and possibly the subfloor. This requires professional assessment. A certified mold inspector can use moisture meters and thermal imaging to determine the full extent of the water damage and take air/surface samples to identify the species, which dictates the remediation protocol.

For a leak of several months, a dedicated remediation company is strongly advised. They will follow protocols to contain the area, safely remove contaminated porous materials like carpet and underlay, and use specialized equipment like HEPA vacuums and air scrubbers to properly clean the area. Simply cleaning the surface will not remove the spores and mycotoxins embedded deeper, leading to recurring issues and potential health effects. After remediation, a post-clearance test from an independent lab is the only way to verify the space is truly safe.
