Black mold in bedroom closet: call building or specialist?« Back to Previous Page

Start by informing your building management immediately. In Dubai, landlords and building owners are generally responsible for addressing structural issues that lead to mold, such as leaks from external walls or faulty AC condensation lines. Document the issue with clear photos and a formal written notification to them.

Given the mold is on an external wall, this strongly suggests a hidden leak or significant condensation issue, likely from a breach in the building's waterproofing or a problem with the HVAC system. The high humidity here means mold can spread inside wall cavities if the moisture source isn't fixed.

While building management may send their own maintenance, a specialist assessment is often necessary for a hidden problem like this. They use moisture meters and thermal imaging to find the exact water source behind the wall, which is critical for a permanent fix. Simply cleaning the visible mold without addressing the hidden moisture is ineffective.

For a confirmed case like this, a professional inspection is the most reliable path. They can determine if the wall needs to be opened for drying and remediation, and their documented report can also be essential for your communications with the building owner to ensure the repair is done properly.
