How to safely clean and prevent AC mold in Dubai?« Back to Previous Page

Based on the symptoms you've described—water leakage and black spots on the skirting board—this is a classic case of moisture intrusion leading to microbial growth, a common issue in Dubai due to our high ambient humidity and year-round reliance on AC systems.

The black spots are likely Stachybotrys or Cladosporium, molds that thrive on the cellulose in damp building materials like drywall and carpet backing. Simply wiping the surface is insufficient and can aerosolize spores. The first step is to identify and rectify the AC condensate drain line blockage or insulation failure that caused the leak; a recent service does not always guarantee this was addressed.

For a small, contained area (under 10 sq. ft.), you can carefully clean non-porous surfaces like the skirting board with a solution of detergent and water, followed by a disinfectant registered for mold remediation. However, the carpet and its underlay are highly porous. If the carpet backing is wet, professional-grade extraction drying is required immediately to prevent structural damage and further colonization within 48-72 hours. Crucially, any water-damaged porous materials that cannot be thoroughly dried must be discarded according to Dubai Municipality waste handling guidelines.

Given the propensity for hidden growth inside wall cavities and the health risks of improper handling, I strongly recommend a professional assessment. Our certified inspectors use thermal imaging and moisture meters to identify the full extent of the moisture and contamination. For a definitive remediation protocol that complies with local regulations, contact our team for an inspection. Call 800-MOLDS or email hello@saniservice.com to schedule. Prevention involves regular, professional HVAC servicing and maintaining indoor relative humidity below 60% using dehumidifiers if necessary.
