How to stop AC leak mold in Dubai apartment permanently?« Back to Previous Page

The water leak is causing the mold, and stopping the leak is the only permanent solution. The black spots are a surface sign of a moisture problem. In Dubai's climate, with high humidity and year-round AC use, condensation is a primary culprit. First, have your AC unit's condensate drain line inspected; it's often clogged with algae or dust, causing the pan to overflow. A general handyman can often clear this.

For the existing mold, a solution of white vinegar or a diluted bleach mixture (1 part bleach to 10 parts water) can clean non-porous surfaces like the window sill. However, if the mold has penetrated the porous drywall or plaster, surface cleaning won't be sufficient. The affected section may need to be cut out and replaced to prevent spores from lingering.

To stop it from returning, ensure the AC leak is fully resolved. Afterwards, improve ventilation in the room when possible and consider using a dehumidifier to keep indoor humidity levels below 60%, which significantly slows mold growth. For persistent issues, a professional inspection can identify the exact mold species and the extent of the problem, especially if the wall cavity is affected, which is common in these scenarios.
