AC leak causing black mold: emergency or wait for maintenance?« Back to Previous Page

Yes, this requires immediate professional attention and should not wait for a general maintenance visit. In Dubai's high humidity, an active water leak combined with AC condensation creates an ideal environment for mold to proliferate rapidly, often within 24-48 hours. The visible spots on the skirting board are likely just a small indication; the growth is probably more extensive inside the wall cavity and under the carpet padding.

Your first step is to stop the moisture source. Place a bucket under the AC leak, turn off the unit's breaker to prevent electrical hazards, and move the curtain away to allow airflow. Do not attempt to scrub the visible mold yourself, as improper cleaning can aerosolize spores and spread them further.

For a situation involving structural elements like walls and flooring, a specialist inspection is strongly advised. They use moisture meters and thermal imaging cameras to assess the full extent of water damage and hidden mold growth behind surfaces, which a maintenance person's visual inspection will miss. Proper remediation involves containing the area, removing affected porous materials like damaged drywall or carpet, and using industrial-grade HEPA filtration to clean the air.

Document the leak and visible damage with photos and immediately notify your landlord in writing. Under Dubai rental law (RERA), landlords are typically responsible for addressing maintenance issues that affect the property's habitability, including mold caused by leaking AC units. A professional assessment provides the documentation needed to ensure the repair is completed to a standard that protects your health and the property. Waiting a week allows the problem to become significantly worse and more costly to fix.
