Mold on bedroom wall: landlord or professional first?« Back to Previous Page

First, document the mold with clear photos and notify your landlord in writing immediately. Under Dubai rental law (RERA), landlords are generally responsible for fixing issues related to the building's structure, which includes water infiltration leading to mold. Do not attempt to clean it yourself, as improper methods can aerosolize spores and worsen the problem.

The location on an exterior wall strongly suggests a hidden issue driving the growth, likely condensation from the AC unit or, more seriously, water seepage from outside. Given Dubai's high humidity and the recent weather, condensation within the wall cavity is a common culprit. A professional inspection is necessary to identify the exact moisture source—whether it's a leaking pipe, capillary rise from the foundation, or a breach in the external waterproofing.

While you wait for your landlord's response, improve air circulation in the room by moving the wardrobe slightly away from the wall and ensuring your AC is set to a consistent, cool temperature to reduce humidity. Keep the area dry.

For a case this advanced, a professional assessment is highly recommended before any remediation begins. An inspector will use moisture meters and thermal imaging to pinpoint the source and take surface or air samples for lab analysis to identify the mold species. This report provides the concrete evidence needed to ensure your landlord addresses the root cause, not just the visible spots. Without fixing the moisture issue, the mold will return quickly. If your landlord is unresponsive, you can escalate the matter to the Dubai Land Department's Rental Dispute Center (RDC), and a professional report will be your strongest evidence.
