Is black and green mold in bedroom a serious issue?« Back to Previous Page

Black and green mould in a bedroom, particularly with a damp smell, is a health and property concern that warrants immediate attention. The combination of colours suggests multiple species may be present, some of which can produce allergens and irritants.

In Dubai's climate, this is a common issue. Year-round AC use creates cold surfaces, and when combined with the high humidity from outside air, it leads to condensation—often behind furniture like wardrobes placed against exterior walls. This trapped moisture is a perfect breeding ground for mould.

For a patch that is actively spreading and causing a noticeable odour, professional assessment is strongly recommended. While small, isolated spots can sometimes be addressed by the homeowner, your description of it spreading from the corner indicates a potential moisture issue within the wall itself that needs proper diagnosis. A certified inspector can identify the mould type and, more importantly, locate the moisture source to prevent recurrence. They use tools like moisture meters and thermal cameras to see inside walls, which is crucial for an effective, long-term solution.

Do not wait until the weekend. In the interim, ensure the area is well-ventilated but avoid disturbing the mould by scrubbing it, as this can release spores into the air. Keep the wardrobe away from the wall to allow air circulation. A professional inspection will determine if remediation is needed and provide a scope of work based on Dubai Municipality guidelines for environmental health and safety.
