How to remove and prevent mold on external wall?« Back to Previous Page

The mold you're describing on the external wall of your wardrobe is a common issue in Dubai, primarily driven by the high humidity and the thermal bridging effect. The external wall is colder than the interior air, especially with year-round AC, causing condensation to form inside the wardrobe—a perfect breeding ground for mold.

For effective removal, safety is paramount. Isolate the area, wear an N95 mask, gloves, and goggles. Do not attempt to clean it with bleach, as it only removes the color and can release harmful vapors. Instead, use a dedicated EPA-approved fungicide or a solution of distilled white vinegar and water. Scrub the area thoroughly. However, this addresses only the surface growth. The hyphae (root structure) often penetrate the plaster, meaning the problem will almost certainly return.

Given the location on an external wall and the associated health symptoms, this is a case that warrants a professional inspection. We use thermal imaging cameras to identify the exact point of condensation and moisture meters to determine the moisture content within the wall itself. The remediation protocol involves removing the affected plaster, treating the cavity with antimicrobial agents, and reinstating with mold-resistant plasterboard. To prevent recurrence, a professional-grade dehumidifying system or improving the wardrobe's ventilation is crucial, alongside addressing any potential external water ingress.

For a definitive solution and to ensure your family's health, I strongly recommend a certified inspection. Contact our team at Saniservice for a comprehensive assessment. Call 800-MOLDS (800-66537) or email hello@saniservice.com.
