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

This is a classic issue we see in older Dubai buildings, especially in areas like Jumeirah. That persistent dampness and cold spot on an interior wall is a major red flag, often pointing to a missing or compromised vapor barrier within the wall cavity, allowing humid air to condense on the cooler internal surfaces. Leather and shoes are prime targets for mold growth in these conditions.

First, stop the source. You need to lower the relative humidity in that closet immediately. While the AC is on, it might not be circulating air effectively into that enclosed space. I strongly recommend a few temporary measures: get a portable dehumidifier and run it in the bedroom, leave the closet doors open as much as possible, and consider a small rechargeable desiccant dehumidifier inside the closet itself for targeted control.

For a permanent fix, this likely requires professional intervention. The root cause needs to be diagnosed. It could be the vapor barrier, but also potentially a small, hidden plumbing leak or insufficient insulation around an AC duct running in that wall. DIY cleaning will only provide a temporary solution; the mold will return without addressing the moisture source.

Our certified inspectors use thermal imaging cameras and moisture meters to pinpoint the exact condensation point without destructive investigation. Remediation would involve correcting the insulation/vapor barrier issue and a professional antimicrobial treatment to ensure the spores are eradicated.

Given the health risks associated with active mold growth and the potential for structural damage, I'd advise a professional assessment. We can determine the exact cause and provide a guaranteed solution.
