How to permanently fix damp smell in closet after rain?« Back to Previous Page

The damp smell returning after cleaning indicates active mold growth inside the wall cavity, a common issue in Dubai villas after heavy rain. Moisture from the rain event was likely absorbed by the porous aerated concrete blocks, and it's now trapped behind the plaster and paint, creating a perfect environment for mold.

Vinegar only addresses surface mold you can see, not the source. The most effective long-term solution requires a professional assessment to confirm the moisture source and extent. They will use a moisture meter to pinpoint the damp areas and a boroscope to inspect inside the wall. The permanent fix typically involves carefully removing a section of the affected plasterboard to allow the wall cavity to completely dry out. The interior structure must then be treated with antimicrobial solutions before new, moisture-resistant plasterboard is installed.

To prevent recurrence, ensure the villa's exterior wall sealant and waterproofing are intact, as the intense sun here degrades them over time. Keep the closet slightly away from the wall and run a small desiccant dehumidifier inside for a few weeks after remediation to control the high ambient humidity. For leather goods, wipe them down with a dilute soap solution and allow them to dry fully in a less humid room before returning them.
