Black mold in Dubai villa - landlord's responsibility?« Back to Previous Page

Black mold on an exterior wall in a Jumeirah villa is a common issue here, primarily driven by thermal bridging. The outside heat meets your cooled interior wall, causing condensation inside the wall cavity. This trapped moisture, combined with our high humidity, creates the perfect environment for mold.

Under Dubai rental law (Law No. 26 of 2007), the landlord is typically responsible for remedying structural issues that cause dampness and the resulting mold. This includes problems with external wall insulation, leaks, or faulty AC systems that fail to control humidity properly. Your first step is to formally notify your landlord or property manager in writing, with clear photos. They are obligated to investigate and address the root cause.

Do not attempt to clean this yourself with bleach, as it will not address the moisture source and can disturb toxic spores. For a growth of this size and location, a professional inspection is strongly advised to assess the hidden extent within the wall and identify the exact species. The remediation process here involves three steps: identifying and fixing the moisture source (e.g., improving insulation, repairing seals), physically removing the contaminated materials (drywall, insulation) under containment, and treating the area with antimicrobial solutions.

Until it's resolved, keep the AC on consistently to help manage indoor humidity levels and improve air circulation in the room. A reputable local remediation company can provide a detailed assessment and scope of work for your landlord to review.
