Is black mold dangerous and landlord's responsibility?« Back to Previous Page

Black mold in bathroom silicone is a common issue in Dubai's humid climate, where condensation from showers and year-round AC use creates ideal conditions for growth. The type and quantity determine the risk; it can certainly cause the symptoms you describe—stuffy nose, sore throat, and irritation—especially over prolonged exposure.

In a Marina apartment, responsibility typically falls to the landlord for structural repairs and issues originating from building defects, like leaking pipes within the walls. As the tenant, you are generally responsible for maintenance stemming from daily use, such as resealing the shower to address moisture ingress. However, if the mold growth is extensive or has penetrated behind tiles or walls due to a hidden leak, the source must be identified. Document the issue with photos and formally notify your landlord or property management company. They should arrange an inspection to determine if a underlying leak exists.

For severe, recurring, or hidden mold, a professional inspection with moisture mapping and possibly air or surface sampling is advised to assess the full scope. In the meantime, improve ventilation by running the exhaust fan longer after showers and wiping down wet surfaces. Temporary cleaning of visible surface mold with a vinegar solution can help, but complete removal requires fixing the moisture source and replacing contaminated materials like the silicone sealant.
