Removing black mold in bathroom: landlord or professional first?« Back to Previous Page

Black mold in bathrooms is a common issue in Dubai due to high humidity and condensation from year-round AC use. For a sudden, spreading growth, especially with health symptoms present, your first step is to notify your landlord in writing immediately. Under Dubai rental law, the property owner is typically responsible for resolving issues that affect the property's habitability and your health.

While waiting for a response, improve ventilation by running the bathroom exhaust fan for at least 30 minutes after showers and keeping the door open. Wipe down wet surfaces to reduce moisture. For small patches, a solution of white vinegar or a dedicated mold remover can temporarily clean the surface, but this rarely addresses the root cause if the mold is growing behind tiles or in the wall.

Given the spread you describe and the coughing, a professional inspection is strongly advised. Surface cleaning often misses hidden moisture and mold within walls, especially behind toilets where leaks can occur. A proper inspection uses moisture meters and borescopes to find the source. The humidity will cause it to return unless the underlying dampness is fixed, which usually requires professional-grade dehumidifiers and sealing.

For health safety, a lab test can identify the mold species, which is crucial information if your children are symptomatic. Your landlord may prefer to hire a general handyman, but for persistent mold with health impacts, a specialist company with the right diagnostic tools is more effective for a permanent solution. They can provide the documentation your landlord may require to approve the work.
