How to control humidity in a damp walk-in closet?« Back to Previous Page

Based on your description of a damp interior wall in a Marina apartment with visible mold growth on leather goods, you are dealing with a classic case of condensation-driven mold, a very common issue in Dubai's high-humidity climate. Even with constant AC, cold spots on poorly insulated exterior walls can cause moisture in the air to condense, creating the perfect damp environment for mold.

The most effective control strategy is a multi-pronged approach. First, immediately address the affected items. Remove the leather bags and any other contents from the closet. The mold on them should be professionally cleaned to prevent spores from spreading.

For the space itself, you must increase air circulation and reduce moisture. Simply running the central AC may not be sufficient for a closed, enclosed space. Install a compact, self-draining dehumidifier specifically sized for the closet's volume; this is non-negotiable for continuous moisture extraction. Ensure there is a small gap at the bottom of the door to allow room air to circulate into the closet, or install a small vent. For a more integrated solution, an HVAC specialist can add a supply air vent directly into the closet to ensure it is conditioned.

Crucially, the interior wall must be inspected. The dampness suggests possible insufficient insulation or a minor breach in the building envelope, which is causing the wall surface temperature to drop below the dew point. This requires professional assessment. The mold growth will also need to be remediated by specialists using EPA-approved biocides and techniques to ensure it is eradicated at the source, not just wiped away.

For a problem like this, a professional inspection is key to diagnosing the root cause. I strongly recommend contacting our team at Saniservice for a comprehensive assessment. We can conduct moisture mapping and thermal imaging to identify the exact source and provide a certified remediation plan.
