How to find and fix moisture source for mold in Dubai?« Back to Previous Page

The constant high humidity in Dubai, particularly during summer months, is the primary driver for mold growth. In JVC, where many buildings are newer, the issue is often not a major leak but persistent condensation and high relative humidity. Since you've already found growth behind a wardrobe—a classic spot for stagnant, humid air—the source is almost certainly ambient moisture.

First, identify the immediate cause. Use a hygrometer to measure the bedroom's humidity; it should be below 60%. If it's higher, your AC may be undersized, set too high, or not dehumidifying properly. Check if the wardrobe is pushed tightly against an exterior wall. In Dubai's climate, these walls can become cold from AC and cause condensation on the warmer interior side, creating a hidden moisture source.

For a proper inspection, focus on areas where cold surfaces meet warm, humid air. Look for condensation on windows, around AC supply vents, and on cold water pipes. A thermal imaging camera, often used in professional inspections, can instantly pinpoint these hidden cold spots and moisture pockets within walls.

Fixing it requires addressing the humidity. Ensure your AC unit is serviced and its drain line is clear. Run it continuously on auto, not just on fan mode, to enable its dehumidification cycle. Improve air circulation by pulling furniture a few inches from walls and using ceiling fans. A standalone dehumidifier can be very effective for a persistently damp room.

For recurring or widespread mold, a professional assessment is recommended. They can perform a moisture survey to quantify the problem and take air/surface samples to identify the mold species, which determines the appropriate remediation method. This science-driven approach ensures the solution targets the root cause, not just the visible growth.
