Landlord or professional for black bathroom grout mold?« Back to Previous Page

The black discoloration in your bathroom grout in Jumeirah Village Triangle is a very common issue in Dubai, and it is almost certainly mold or mildew. The combination of high humidity from showers and year-round AC usage, which can create condensation, provides the perfect damp environment for microbial growth. Regular scrubbing often fails because the mold penetrates deep into the porous grout.

Under typical UAE rental contracts (EJARI), the landlord is responsible for structural and maintenance issues, while the tenant handles routine cleaning. However, the line can be blurry. If the mold growth is superficial due to a lack of ventilation or cleaning, it may be considered a tenant responsibility. But if it is pervasive, indicating a potential underlying moisture issue like a leaking pipe or faulty waterproofing behind the tiles, this is a structural defect the landlord must address.

I strongly recommend a professional inspection first. Attempting to clean a serious infestation yourself can aerosolize spores and worsen indoor air quality. A certified expert can determine the root cause—whether it's surface-level or a sign of a hidden problem.
