How to remove mold from closet or call professional?« Back to Previous Page

Based on your description of black fuzzy spots, a damp smell, and location on an exterior wall that has been exacerbated by recent humidity, you are almost certainly dealing with a significant active mold colony. The climate in Dubai, with its high humidity levels and the constant use of air conditioning which can create temperature differentials and condensation on cold surfaces, is a primary catalyst for such growth.

For a small, surface-level patch (less than 10 square feet), a DIY approach can be attempted. First, isolate the area by sealing the closet with plastic sheeting. Wear an N95 respirator, gloves, and eye protection. Hard surfaces can be scrubbed with a detergent solution. However, porous materials like drywall, insulation, or the backing of shelves are nearly impossible to clean effectively; they typically require removal and replacement. Crucially, DIY methods only address the visible growth, not the underlying moisture source. In your case, the exterior wall location suggests a potential insulation or vapor barrier issue that is allowing condensation to form inside the wall cavity. This is a serious concern.

Given the spread you've described and the fact it's on a critical building envelope component, I strongly recommend you halt any DIY efforts and call a professional. Disturbing the mold without proper containment and air filtration can cause spores to aerosolize and spread throughout your bedroom and HVAC system.

In the UAE, professional remediation companies like Saniservice follow strict IICRC guidelines. We conduct a thorough inspection, including moisture mapping and often air quality testing, to identify the full extent of the contamination and the root cause. The process involves engineering controls (negative air pressure containment, HEPA filtration), safe removal of affected porous materials, and specialized antimicrobial treatments to ensure the mold is eradicated, not just cleaned.

For a proper assessment and to prevent further damage to your property and health, please contact our experts. Call 800-MOLDS (800-66537) or email hello@saniservice.com for a consultation.
