Is black grout and smell a landlord's responsibility?« Back to Previous Page

Black grout and a persistent damp smell are almost certainly a sign of active mold growth, which is extremely common in Dubai bathrooms due to high humidity and condensation from shower use. The primary concern is the moisture source, which is often a leaking pipe, failed waterproofing, or cracks behind the tiles that allow water into the wall cavity.

In the UAE, the responsibility for repair depends on the cause. As a tenant, you are typically responsible for minor maintenance and surface cleaning. However, the landlord is responsible for fixing structural defects and issues with concealed installations, like internal plumbing or the integrity of the waterproofing membrane, as these are considered part of the property's main structure. Since the problem is spreading and has a persistent odor, it strongly suggests a concealed leak or seepage, which falls under the landlord's obligation to rectify.

Your first step is to formally notify your landlord or building management in writing, detailing the issue and requesting an inspection for the moisture source. They are obligated to address problems that affect the property's habitability. For a case like this, a professional inspection is advised to identify the exact moisture source using tools like moisture meters; surface cleaning alone won't solve it. Remediation often involves removing affected grout, treating the area, and repairing the leak before re-grouting and sealing.
