Black fuzzy wall patches in villa: landlord or my responsibility?« Back to Previous Page

In Dubai villas, the responsibility for mold remediation depends on the source of the moisture. If the black patches are caused by a structural issue like a leaking pipe in the wall, a faulty external sealant, or rising damp due to a missing damp-proof course, the landlord is typically responsible for the repair under UAE tenancy law. However, if the moisture is due to tenant lifestyle factors—such as insufficient use of AC/dehumidifiers to combat the high humidity, drying clothes indoors, or blocking ventilation with furniture—the cost of cleaning may fall to you.

Given its location behind a sofa, condensation from the wall's temperature differential with the room is a likely culprit, exacerbated by Dubai's climate. The first step is to inform your landlord or property manager in writing with photos. They should arrange a professional inspection to identify the moisture source; this is crucial, as simply cleaning the mold without fixing the underlying cause will lead to its return. A proper assessment often requires moisture meters and thermal imaging.

For remediation, the area should be isolated, the mold removed with HEPA-filtered equipment, and the underlying moisture issue resolved. DIY cleaning with bleach is not recommended as it can aggravate spores and doesn't address the root problem. Since you've noted a persistent damp feeling, a professional assessment is strongly advised to determine the extent and source. A company with its own microbiology lab can identify the mold type, which helps in understanding potential health risks and verifying the success of the cleanup.
