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

The master bedroom closet in our Jumeirah villa has a persistent damp smell, and we just discovered black spots on a few of my winter jackets and shoes tucked in the back. This seems to happen every year after the humidity spikes in winter, even though we run the AC constantly. What’s the most effective way to treat the existing mold and what can we do to our closet space to stop it from coming back next season?

The issue you're describing in your Jumeirah villa is a classic case of localized mold growth, a common problem in Dubai due to our unique climate. The combination of high external humidity, particularly during the winter months, and the constant cooling from your AC creates significant condensation, providing the perfect environment for mold spores to colonize.

First, for the existing mold: Do not attempt to clean it with bleach. This can exacerbate the problem by releasing a high volume of spores and only removes the surface discoloration, not the root structure. For porous materials like leather shoes and jackets, professional cleaning is often required to salvage them. The affected closet must be isolated. The items should be carefully removed and sealed in plastic bags to prevent cross-contamination. The area should then be HEPA-vacuumed and treated with an EPA-approved antimicrobial solution by a trained technician to ensure complete eradication.

To prevent recurrence, you must address the moisture source. Simply running the AC is not enough; it must be correctly balanced for dehumidification. I recommend installing a standalone, compact dehumidifier inside the closet, such as a mini-desiccant model, to maintain humidity levels below 60%. Ensure there is a small air gap between the wall and your clothing to promote air circulation. Inspect the room's AC vent; it should be unobstructed and blowing air into the closet space, not away from it. Adding a moisture barrier, like a foil-backed insulation panel, to the closet's interior wall can also prevent condensation from forming due to the temperature differential between the cooled room and the warmer external wall.

For a persistent issue like this, a professional inspection is crucial. We use thermal imaging cameras to identify hidden condensation points and moisture meters to quantify the problem, which is often beyond a visual assessment. Saniservice's certified experts can provide a comprehensive remediation plan and post-clearance testing to ensure the environment is safe.
