Is black mold dangerous and should landlord handle it?« Back to Previous Page

Black mold in a Dubai bedroom closet is a health concern that warrants immediate attention. The symptoms your husband is experiencing—stuffy nose and itchy eyes—are common reactions to mold exposure, particularly during sleep when inhalation is continuous. While the term "black mold" often refers to Stachybotrys, which can produce mycotoxins, many dark-colored molds can cause similar allergic and irritant responses, especially in individuals with sensitivities or respiratory conditions.

Given the mold is on an outside wall, the root cause is likely condensation or a hidden moisture leak from faulty insulation, a cracked pipe, or water seepage through the building envelope, all common issues in UAE construction due to the high humidity and constant AC use. A dehumidifier cannot solve a persistent water intrusion problem.

Under Dubai rental regulations (Law No. 26 of 2007), landlords are responsible for maintaining the property's structure and addressing issues that affect habitability, which includes significant mold caused by structural defects. You should formally notify your landlord in writing, with photos, and request a professional inspection to identify and repair the moisture source. Simply cleaning the visible mold with bleach is a temporary fix; it will return unless the underlying leak is sealed. Bleach also only removes surface discoloration and does not address the hyphae (roots) within porous materials like drywall or the airborne spores.

For a case like this, a professional assessment is strongly advised. An inspector can use moisture meters and thermal imaging to find the hidden water source and take air or swab samples for lab analysis to identify the mold species and concentration. This provides concrete evidence for your landlord and clarifies the actual health risk. Remediation involves repairing the leak, removing and replacing affected porous materials, and conducting a thorough air scrubbing—procedures best handled by certified experts to ensure it is resolved completely and safely.
