Black mold in Dubai bedroom: landlord's responsibility?« Back to Previous Page

In Dubai, landlords are generally responsible for maintaining the property's structural integrity and addressing issues that make it uninhabitable, which includes persistent dampness and mold caused by building envelope defects. Your situation—black mold on an interior wall with a constant damp feeling—strongly suggests an underlying moisture issue, likely from a hidden plumbing leak or, very commonly here, condensation due to thermal bridging. This occurs when the cold from the AC unit in an adjacent room or the chilled ceiling system meets Dubai's high outdoor humidity, causing water to condense inside the wall.

You should formally notify your landlord in writing (email is best) with clear photos. Under typical Dubai rental contracts (EJARI), the landlord is obligated to investigate and rectify the source of the dampness. However, the responsibility for testing the mold itself can be less clear-cut. While they must fix the leak, they may not cover the cost of environmental testing to identify the species.

For a case like this, a professional inspection is critical. The visible mold is often just the surface manifestation; the main colony is usually hidden inside the wall cavity. A proper assessment involves moisture mapping with a thermal camera and borescope inspections to find the exact source. Treatment is ineffective until the moisture problem is solved. DIY cleaning with bleach is not recommended as it only bleaches the surface and does not address the root cause or remove the deeper mycotoxins.

A reputable remediation company will first identify and stop the water intrusion, then contain the area, remove contaminated materials like drywall, use HEPA vacuuming and antimicrobial treatments, and finally verify the cleanup's effectiveness with post-remediation testing. Always request a detailed report with before-and-after lab results to confirm the spore count has returned to normal indoor levels. This documentation is also important for your landlord to confirm the issue is fully resolved.
