How to permanently treat and prevent mold in Dubai?« Back to Previous Page

The damp AC and recurring mold spots point to a classic Dubai humidity problem, not just a surface issue. Effective treatment requires addressing the moisture source first, as surface cleaning alone will always fail here.

Start by having a certified technician inspect your AC unit. The constant dampness suggests the evaporator coils are likely not draining properly or the unit is oversized, causing excessive condensation—a common issue in JVC apartments. They should check the condensate drain pan and line for blockages and ensure the drain trap is functioning. This is the primary moisture source feeding the mold.

For the walls and wardrobe, scrubbing with a diluted vinegar or hydrogen peroxide solution can remove visible growth, but it will return if the room’s humidity isn’t controlled. Given our climate, a professional-grade dehumidifier is often necessary to keep indoor humidity below 60%, the threshold where mold struggles to grow. Ensure your AC is running consistently, even when you're out, to maintain a stable, dry temperature.

For prevention, improve air circulation behind furniture. Pull your wardrobe slightly away from the wall. Consider applying an anti-microbial coating to the affected walls after they are professionally dried and cleaned, as these surfaces are now more susceptible to regrowth.

If the problem recurs after these steps, the mold may have penetrated the porous materials like drywall or insulation. A professional inspection with moisture mapping is needed to assess the extent. Companies with their own microbiology labs can identify the species and provide a targeted remediation protocol, which is the only way to achieve a permanent solution in our high-humidity environment.
