How to stop AC leak mold in my Dubai villa?« Back to Previous Page

The black spots you're observing behind the curtain are a classic indicator of mold growth, directly caused by the AC leak and exacerbated by Dubai's high humidity. This is a very common issue in villas here. The moisture from the leak, combined with condensation and the organic material in the gypsum board (drywall), creates an ideal environment for mold proliferation.

Do not attempt to clean this with bleach or household cleaners. These are ineffective on porous surfaces like drywall and can actually exacerbate the problem by adding more moisture. The first and most critical step is to stop the source of the moisture. You must have a certified HVAC technician repair the AC condensate drain line or pan that is leaking. Until that is fixed, any cleaning is futile.

Given the visible growth, the wall cavity likely has a more extensive contamination. The standard protocol involves containment of the area to prevent spore dispersal, removal of the affected drywall section, HEPA vacuuming, and antimicrobial application. This is not a DIY job due to the health risks from disturbed spores and the technical precision required for proper remediation.

I strongly recommend a professional inspection. Our certified mold assessors at Saniservice use moisture meters, thermal imaging, and air sampling to determine the full extent of the problem, which is often far greater than what is visible on the surface. We provide a detailed remediation protocol to ensure the mold is removed safely and effectively, preventing its return. For a lasting solution in our challenging climate, professional intervention is key.
