Black mold behind wardrobe: urgent or DIY cleaning?« Back to Previous Page

This is likely a moisture issue and should be addressed with caution. Black spots spreading on an interior wall strongly suggest a hidden problem, like condensation from the AC unit or a slow leak in a pipe within the wall. The damp feeling confirms high humidity is trapped there.

In Dubai's climate, year-round AC use can cause significant condensation if units are not draining properly or are set too cold. The wall behind the wardrobe is a prime spot for this, as lack of airflow allows moisture to accumulate and mould to thrive.

For a small, surface-level area (less than 1 square meter), you can clean it yourself with a vinegar solution or a dedicated mould remover. Wear an N95 mask and gloves. However, simply cleaning the visible mould is a temporary fix if the underlying moisture source isn't identified and resolved. It will almost certainly return.

Given that it's spreading and the room feels persistently damp, a professional inspection is recommended. They can use moisture meters and thermal imaging to locate the exact source of the water intrusion without damaging your walls. For rental properties, this is often the landlord's responsibility to rectify. If the mould is extensive or you have health concerns, a lab test can identify the species and inform the correct remediation approach.
