How to prevent mold in a Dubai villa storage room?« Back to Previous Page

The black speckled spots you've described are a classic sign of a mold colony, likely Cladosporium or Aspergillus, thriving due to the specific environmental conditions in your storage room. The primary issue is not just the AC but the lack of air circulation and temperature control in that specific space, which creates a microclimate of stagnant, humid air—a perfect breeding ground for mold, especially given Dubai's high ambient humidity levels that often exceed 90%.

The most effective strategy is to control the Relative Humidity (RH) within the room. Your target should be to maintain RH below 60%, which is the threshold to inhibit mold growth. Since extending your AC ducting might be impractical, I recommend a two-pronged technical approach. First, install a standalone, energy-efficient dehumidifier with a built-in hygrometer set to maintain 50-55% RH. This is non-negotiable for enclosed, non-AC spaces here. Second, you must drastically improve air circulation. Install a ceiling-mounted exhaust fan vented to the outside or use a high-capacity oscillating fan running on a timer for several hours daily to prevent air stagnation.

For the contents, immediately remove the affected leather items for professional restoration cleaning to prevent spore dissemination. Before returning any items, ensure they are completely dry and consider storing them in sealed vacuum bags with silica gel desiccant packs.

Given that visible growth is already present, this indicates a established problem. I strongly recommend a professional inspection. Our certified team at Saniservice can conduct a comprehensive assessment, including moisture mapping and air quality testing, to identify the full extent of the contamination and develop a targeted remediation plan to protect your property and health.
