Black mold in bedroom corner—who to call in Dubai?« Back to Previous Page

That black spot pattern is a classic sign of a condensation issue, very common here due to the high humidity and constant AC use. The corner is likely a thermal bridge where cooler outdoor air meets the humid indoor air, causing moisture to condense and mould to grow.

Your first call should be to your building management. Under Dubai regulations, they are responsible for the building envelope, including external walls and windows where leaks or insulation failures can occur. Report the issue and request an inspection for potential water intrusion or inadequate insulation in that corner.

If the building management confirms it's not a structural issue or the problem persists after their repair, then a specialist inspection is needed. A professional can use a moisture meter to identify the exact source of dampness and take an air or tape-lift sample for lab analysis to confirm the mould type. This is crucial, as the remediation approach differs for various species.

For a patch that size, especially after it has spread, DIY cleaning is not advised. You might temporarily remove the visible growth but miss the underlying moisture problem, guaranteeing it will return. In Dubai's climate, controlling humidity with properly serviced ACs and using dehumidifiers in problem rooms is key to preventing recurrence after the root cause is fixed.
