How to handle mold bathroom in Dubai?« Back to Previous Page

Black mould in bathroom grout is common in Dubai due to the high humidity and condensation from showers. The musty smell indicates active microbial growth, and the humidity spike in January likely accelerated it.

As a tenant, you should report this to your landlord or property management company immediately. Under standard tenancy agreements in Dubai, structural issues like potential mould behind walls are typically the landlord's responsibility to investigate and remediate. Provide them with photos and a description of the persistent musty odour, as this suggests it may not be a surface-level issue.

For now, increase ventilation by running the bathroom exhaust fan for at least 30 minutes after showering and wiping down wet surfaces. Avoid using bleach, as it only removes surface colour and doesn't address the root cause. Scrubbing can also release spores.

A professional inspection is advised to assess if there's hidden growth behind the tiles. They use moisture meters and borescopes to check wall cavities non-invasively. If the mould is widespread or there's evidence of water damage, remediation by a certified company is necessary to prevent recurrence and protect indoor air quality.
