How to permanently fix AC leak causing mold in closet?« Back to Previous Page

The mold growth you're describing is a direct result of the AC condensate leak and the high humidity levels typical of Dubai's climate. This is a serious issue that requires a systematic, professional approach for a permanent fix, not just a surface cleaning.

First, you must stop the water source. The leak is likely due to a blocked or disconnected condensate drain line, a damaged drain pan, or insufficient insulation on the cold water lines causing excessive condensation. A certified HVAC technician should inspect the unit, clear any blockages with a vacuum or pressurized jet, and ensure the drain line is properly routed and insulated. In villas, improper slope or damage to the concealed drain pipe within the wall is common.

Once the leak is repaired, the mold remediation begins. This is not a DIY job. The mold on the surface is just the visible part; the hyphae (root system) will have penetrated the porous wall and shoe materials. Proper remediation involves containment of the area with negative air pressure to prevent spore dissemination, HEPA vacuuming, and antimicrobial treatment of all affected surfaces. Porous items like the shoes may be unsalvageable. The wall may require cutting out and replacing if the drywall is saturated.

To prevent recurrence, consider installing a dehumidifier in the closet or having your HVAC system serviced to ensure it is correctly balanced and dehumidifying your home effectively, which is critical in our humid environment.

For a permanent solution, this requires a dual approach: an HVAC technician to fix the leak and a certified mold remediation company like Saniservice to handle the contamination safely and in line with Dubai Municipality guidelines. I strongly recommend a professional inspection to assess the full extent. Please call us at 800-MOLDS (800-66537) or email hello@saniservice.com for an assessment.
