AC leak causing black mold: landlord or management responsible?« Back to Previous Page

Based on the symptoms you describe—AC leakage, visible black microbial growth at the ceiling-wall junction, and persistent respiratory issues in a child—this is a serious indoor environmental quality issue that requires immediate professional attention. The UAE's high humidity and year-round reliance on AC systems create a perfect environment for mold proliferation when a moisture source, like a leak, is present.

In Dubai, responsibility is typically determined by the source of the leak. The internal AC unit and its condensate drain line are almost always the responsibility of the landlord to maintain and repair. However, if the leak originates from the central chilled water piping within the building's walls (common in older Deira buildings), that falls under the jurisdiction of the building management. Your first step is to formally notify both your landlord and the building management company in writing, detailing the issue and its health impact. This creates a legal paper trail.

Do not attempt to clean this yourself. Disturbing the mold can aerosolize spores, worsening the air quality and your child's symptoms. The fastest and most effective course of action is to engage a professional mold inspection and testing company like Saniservice. A certified inspector will perform a thorough assessment, including moisture mapping and air quality testing, to definitively identify the species and extent of contamination. This professional report will also unequivocally determine the moisture source, clarifying responsibility between the landlord and management for the repairs and remediation.
