Is black shower grout a tenant or landlord responsibility?« Back to Previous Page

In the UAE, particularly in high-humidity coastal areas like Jumeirah, black discoloration on shower grout is almost always a mold issue, exacerbated by the constant cycle of condensation from hot showers and year-round AC use. The primary responsibility hinges on the source of the problem. As a tenant, your obligation is to perform routine cleaning and maintenance, which you are doing by wiping down surfaces. This addresses surface-level moisture.

However, if the issue is systemic—such as an underperforming building exhaust fan that fails to remove humid air adequately, pre-existing leaks within the walls, or insufficient waterproofing—this falls under the landlord's responsibility for providing a habitable property with functioning systems, as per typical Dubai rental regulations (RERA). A persistently returning mold problem, despite your diligent cleaning, strongly indicates such a deeper, systemic moisture source.

We strongly recommend a professional mold inspection to determine the root cause. Our certified inspectors use tools like moisture meters and thermal imaging cameras to identify hidden leaks and assess ventilation efficiency. This objective report is crucial for liaising with your landlord or building management, as it definitively establishes liability. For remediation of confirmed growth, our team at Saniservice employs industrial-grade HEPA filtration and EPA-approved antimicrobials to ensure the mold is eradicated, not just superficially cleaned.

Do not let this persist, as it can impact indoor air quality. For an expert assessment, please call us at 800-MOLDS (800-66537) or email hello@saniservice.com.
