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

Our master bedroom closet on the outside wall has started to get small black speckles on the leather bags and shoes we store in there. We’re in an older building in Bur Dubai and I’m worried the humidity is getting trapped inside. What’s the most effective way to stop this mold from spreading and damaging our things?

Based on your description of black speckles on leather goods in an external wall closet in an older Bur Dubai building, you are almost certainly dealing with a classic case of mold growth due to condensation and high ambient humidity. The UAE's climate, particularly during the summer months, creates an enormous burden on building envelopes. Older constructions often lack the continuous insulation and vapor barriers required by current Dubai Green Building Regulations, leading to thermal bridging. This is when the cold from your year-round AC condenses the humid outdoor air on the cooler internal surfaces of external walls, creating the perfect damp environment for mold spores to colonize.

The most effective immediate action is to remove all affected items from the closet for cleaning. For leather, use a solution of soapy water (a mild, pH-neutral soap) or a dedicated leather cleaner. Wipe down the interior surfaces of the closet with a diluted vinegar or hydrogen peroxide solution. However, this is only a superficial fix.

To stop the recurrence, you must address the root cause: humidity and temperature differential. First, improve air circulation. Use a small, battery-operated dehumidifier or a desiccant bag inside the closet. Ensure the closet door is left ajar periodically. For a permanent solution, the wall itself may need to be inspected. The issue could be insufficient insulation or even a minor, hidden leak in the external wall or from an AC condensation drain line, which is common here.

Given the location and the value of the items being damaged, I strongly recommend a professional inspection. Our certified inspectors use thermal imaging cameras to pinpoint the exact source of the condensation and moisture meters to quantify the problem, which is crucial for an effective remediation plan.
