Is black mold in my rental shower the landlord's responsibility?« Back to Previous Page

In the UAE's humid climate, especially in areas like Jumeirah Village Circle, persistent black mold in a shower grout is a common but serious issue. The primary cause is almost always excessive and trapped moisture. Your observation that it's worse on an external wall is a critical clue; this often indicates a hidden problem such as a leaking pipe within the wall, poor external waterproofing, or significant thermal bridging causing condensation. Using bleach is a temporary, superficial fix. It may kill surface mold but does not address the root moisture source, and the hyphae (root structure) remain deep within the porous grout, allowing for rapid regrowth.

Regarding responsibility under UAE tenancy law (Law No. 26 of 2007), the landlord is typically responsible for the structural integrity of the property and the maintenance of essential fixtures. This includes the building's waterproofing envelope, internal plumbing, and the proper functioning of ventilation systems. A weak exhaust fan that fails to evacuate humid air is a clear maintenance defect that contributes to the problem. You should formally notify your landlord or property management company in writing, detailing the issue and the suspected causes (leak, faulty fan), and request immediate remediation.

For a case with a strong, recurring odor, a professional inspection is strongly recommended. We at Saniservice use borescopes to inspect inside walls for leaks and moisture meters to quantify the saturation levels. This evidence is crucial for determining the exact cause and scope of work required. Remediation involves fixing the moisture source, proper removal of contaminated materials, and application of antimicrobial coatings to prevent recurrence.
