How to permanently stop AC leak and closet mold growth?« Back to Previous Page

The recurring black spots in your closet are a clear indicator of a persistent mold issue, directly caused by the AC condensate leak. In Dubai's high humidity climate, even a minor, continuous water source like this creates an ideal environment for mold colonization. The most effective, permanent solution requires a two-pronged approach: addressing the moisture source and properly remediating the existing contamination.

First, you must stop the water intrusion. The AC leak is likely due to a clogged condensate drain line, a cracked drain pan, or improper insulation on the cold refrigerant lines causing condensation. A certified HVAC technician should inspect and service the unit to resolve this. Simply wiping the mold is insufficient; the hyphae (root structure) penetrate porous materials like drywall and carpet. The affected section of drywall and the underlying carpet pad are likely compromised and must be removed and discarded. The area then requires professional-grade antimicrobial treatment to eliminate any remaining spores.

To prevent recurrence, ensure the closet maintains airflow; avoid over-packing with clothes. Consider installing a small humidity absorber. For a permanent fix, this situation warrants a professional inspection. We at Saniservice are certified in mold assessment and remediation, following UAE standards for indoor environmental quality.
