Best long-term solution for AC leak and recurring mold?« Back to Previous Page

The recurring mold indicates the underlying moisture issue wasn't resolved. A permanent fix requires addressing both the AC leak and the existing mold colony.

First, a qualified AC technician must properly diagnose and seal the leak in the unit or its drainage line, which is the primary water source. In Dubai's climate, even a minor leak creates constant humidity, allowing mold to thrive. For the mold itself, surface cleaning is insufficient if it has penetrated porous materials like drywall or plaster. The affected section of the wall likely needs to be carefully removed and replaced after the leak is fixed.

Treating the area with an antimicrobial solution is crucial to prevent regrowth from residual spores. Given the location behind a wardrobe, which creates a dark, stagnant air pocket, achieving this without professional equipment is difficult. For a long-term solution, an inspection that includes moisture mapping with a thermal camera can identify the full extent of the water damage and hidden mold you cannot see.

The Dubai Municipality has clear guidelines for property maintenance to prevent such issues. Since this is a recurrence, a professional remediation protocol—not just cleaning—is advised to ensure it is done to a standard that prevents it from returning again next season.
