Should my landlord fix recurring mold in bathroom grout?« Back to Previous Page

Under Dubai rental law, your landlord is responsible for maintaining the property's structure and ensuring it is habitable, which includes addressing persistent dampness and mold that result from building issues like inadequate ventilation or waterproofing. However, if the mold is solely due to tenant lifestyle (like not using the exhaust fan), the responsibility can shift.

In your case, the location behind the toilet suggests a chronic dampness issue, not just surface moisture. Bleach will only remove the visible stain temporarily; it does not kill the mold roots embedded in the porous grout and can actually feed future growth. The high humidity in Dubai, especially in bathrooms with poor airflow, creates a perfect environment for this rapid recurrence.

First, notify your landlord in writing with photos, detailing the specific location and that it persists despite using the exhaust fan. This documents the request. A professional assessment can determine if the fan is underpowered, if there's hidden moisture, or if regrouting with mold-inhibiting products is needed. For a science-based resolution, a company with a microbiology lab can test to identify the mold type and its root cause, providing your landlord with evidence for a proper, lasting fix rather than a superficial clean.
