How to stop closet mold in a humid villa?« Back to Previous Page

Our bedroom closet on the outside wall of our villa in Al Barsha has developed black spots on the leather bags and shoes I stored there. It's been incredibly humid the last few weeks and even though the AC is always on, that corner just feels damp and cold. What's the most effective way to control the humidity in a specific closet to stop this mold from coming back?

That black spotting on leather is a classic sign of a localized humidity problem, especially in closets on exterior villa walls in Dubai. The cold concrete wall behind the closet acts as a thermal bridge, causing condensation when humid room air meets the cold surface, creating a perfect environment for mold.

Start by emptying the closet and cleaning the affected items and interior surfaces with a solution of white vinegar or a dedicated mold-cleaning product. For leather, consult a specialist cleaner to avoid damage.

To stop it from returning, you must control the humidity in that enclosed space. A small, plug-in dehumidifier or reusable desiccant pods (like silica gel) placed inside the closet can help significantly. Ensure there's at least a few inches of space between the back wall and your stored items to allow for air circulation. Leaving the closet door ajar for a few hours each day can also prevent stagnant, moist air from accumulating.

The root cause is likely the temperature differential of that exterior wall. If the problem persists, the wall itself may have insufficient insulation or a hidden leak, which is common after winter rains. For a recurring issue, a professional inspection can identify the exact moisture source—whether it's condensation, capillary rise from the foundation, or a leak—and recommend targeted remediation, which is more effective than temporary fixes.
