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

The recurring mold growth in your villa closet is a classic symptom of a condensation issue, exacerbated by Dubai's high ambient humidity and year-round AC use. The wall facing the exterior is likely a "cold bridge," where the outside heat meets the cooled interior air, causing condensation within the wall cavity. This trapped moisture provides the perfect environment for mold, which is why wiping the surface with vinegar only offers a temporary fix.

For a permanent solution, the underlying cause must be addressed. First, a professional inspection is crucial. We use thermal imaging cameras to identify the exact location and severity of the condensation and moisture meters to assess the wall's moisture content. This diagnosis is essential, as the mold you see is often just the "fruit" of a larger colony hidden within the wall.

The remediation process involves several technical steps: removing the affected drywall or plaster, treating the cavity with specialized antimicrobial agents, and installing new moisture-resistant drywall. However, the key to preventing recurrence is improving the thermal performance of that wall. This typically involves injecting insulation into the cavity or applying an internal insulating plasterboard to raise the surface temperature above the dew point, thereby eliminating condensation.

Furthermore, we recommend installing a dehumidifier or ensuring your AC system is properly balanced to maintain humidity levels below 50%, as per Dubai Municipality's guidelines for healthy indoor air quality.

Given the potential health effects on your children, I strongly advise against a DIY approach.
