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

Our master bedroom closet, which is on the inside wall of our villa in Jumeirah, has a persistent damp smell and I just found a few black spots on some leather bags stored in the back. The dehumidifier runs in the room, but it doesn't seem to help the closet. What's the most effective way to stop this from spreading and prevent it from happening again, especially during the humid summer months?

Based on the description of your villa in Jumeirah, this is a classic case of localized high humidity and poor air circulation within an enclosed space. Even with a dehumidifier in the main room, closets on interior walls often become stagnant air pockets where moisture accumulates, especially on leather which is organic and provides a food source for mold.

First, immediately remove all affected items from the closet. For the leather bags, gently wipe the mold spores with a soft cloth slightly dampened with a water and white vinegar solution (1 part vinegar to 4 parts water), then allow them to dry completely in a well-ventilated area—but not in direct sunlight, as this can damage the leather.

The most effective immediate action is to address the closet's microenvironment. You need to create air movement. I strongly recommend installing a small, battery-operated or USB-powered moisture absorber unit like a Eva-Dry dehumidifier inside the closet itself. These are perfect for enclosed spaces. Additionally, avoid overpacking the closet; leave space between items and the walls. Leave the closet door open for a few hours each day to allow the room's dehumidifier to cycle that air.

For long-term prevention, the root cause must be identified. The persistent damp smell suggests a potential issue that a standard dehumidifier can't solve alone. It could be a minor condensation issue due to the temperature differential between the air-conditioned room and the wall, or something more significant like a hidden plumbing leak or insufficient external wall insulation, which is common in older villas.

Given the climate and the potential for hidden problems, a professional inspection is wise. We use thermal imaging cameras to identify cold spots causing condensation and moisture meters to pinpoint exact humidity levels within the wall cavity. This is crucial to ensure the mold hasn't spread behind the drywall.

For a thorough assessment and a permanent solution, call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com. We can determine if this is a simple ventilation fix or requires remediation to prevent it from recurring next summer.
