Black mold in Dubai rental: DIY or call professional?« Back to Previous Page

In Dubai's climate, that black spot pattern behind a wardrobe is a classic sign of condensation mould. The wall is likely a cold spot where humid air condenses, creating a persistent moisture source for mould growth. Bleach is not recommended; it's mostly water and can feed the mould roots inside porous materials like drywall, while its fumes are hazardous in a bedroom.

For a rental, your first step is to notify the landlord or property management company in writing with photos. Under Dubai rental regulations, structural issues like persistent dampness that affect livability are typically the owner's responsibility to rectify. A professional inspection can document the source and extent, which protects your deposit by proving the cause was pre-existing moisture and not tenant negligence.

DIY scrubbing is only a temporary fix on non-porous surfaces. On drywall, it often spreads spores and disturbs the surface, making the problem worse. A proper remediation involves identifying and stopping the moisture source, then safely removing affected porous materials. Given the spread you've described and the location in a sleeping area, a professional assessment is strongly advised. They can perform ambient air testing to gauge spore levels and use containment procedures to prevent cross-contamination during removal, which is crucial for your health.
