How to handle black mold in UAE villa closet?« Back to Previous Page

The damp wall suggests a moisture source, which is the core issue that must be addressed. In Dubai's climate, this is often due to condensation from an AC supply line running inside the wall or a minor, hidden plumbing leak. Surface cleaning alone is a temporary fix.

For a small, surface-level patch (under one square foot), you can carefully clean it with a diluted vinegar or hydrogen peroxide solution. Wear an N95 mask and gloves. However, since the wall is damp and the mold is likely inside, this will not solve the problem. The moisture will cause it to return.

Professional assessment is strongly recommended here. Remediation involves identifying and stopping the water source, then properly containing and removing the affected building materials to prevent spore dispersal. In many UAE villas, the concrete block and insulation behind the drywall can harbor significant growth if dampness persists. A reputable company will use moisture meters and borescopes to inspect inside the wall cavity and provide a scope of work.

After remediation, the area must be dried to a specific moisture content before repairs. To prevent recurrence, ensure your AC is serviced regularly and set to a consistent temperature to reduce condensation, and improve air circulation in closets by not overpacking them and occasionally leaving the doors ajar.
