How to permanently remove mold from closet in humid weather?« Back to Previous Page

The mold returning worse indicates a persistent moisture source, likely inside the wall cavity itself. In older Jumeirah villas, this is often from condensation on chilled AC ducts running through the space or a small, unseen leak. Scrubbing the surface is temporary because the root cause remains.

Effective removal requires three steps: source identification, material treatment, and moisture control. First, a professional inspection with a thermal imaging camera can pinpoint the exact source of the condensation or moisture intrusion behind the wall. Second, all affected porous materials like drywall or insulation must be removed and replaced, as mold roots deeply into them. Surface cleaners cannot penetrate this. Finally, address the humidity. Ensure your AC is correctly sized and functioning to manage indoor humidity levels, which should ideally be kept below 60%. For a closet, improving air circulation by installing a vent in the door or using a small, standalone dehumidifier can be very effective.

Given the recurrence and your children's symptoms, a professional assessment is strongly recommended. They can conduct air and surface sampling to identify the mold species and confirm the spore count in the bedroom air, which is crucial information for remediation planning and health concerns. The goal is not just to clean what's visible, but to correct the conditions allowing it to grow.
