Urgent: Black mold under shower sealant, notify landlord now?« Back to Previous Page

Yes, notify your landlord immediately. This is a health and habitability issue under Dubai rental law, and the humidity will only accelerate its growth.

Black mold under sealant indicates a persistent moisture problem, either from a leak behind the tiles or constant condensation. The high humidity we experience in Dubai, especially with AC systems creating temperature differentials, provides the perfect environment for this growth. Leaving it allows spores to spread into your bathroom's air and potentially the AC system.

For your health and the property's integrity, document everything with clear photos and a written notice to your landlord or property management company. They are responsible for addressing the underlying moisture issue and the remediation, not just wiping the surface mold away. Proper remediation involves removing the contaminated sealant, treating the area with antimicrobial solutions, fixing any hidden leaks, and allowing everything to dry completely before applying new, high-quality sealant.

While waiting for a response, keep the bathroom well-ventilated by running the exhaust fan for at least 30 minutes after showering and wiping down wet surfaces to minimize additional moisture. Do not attempt to remove it yourself, as disturbing it can release a large number of spores. For severe, widespread growth, a professional inspection can identify the full extent and ensure the remediation is done correctly to prevent a rapid recurrence.
