Black mold behind wardrobe causing coughs? DIY fix safe?« Back to Previous Page

Black spots behind furniture on a damp interior wall are a common issue in Dubai, often caused by condensation or a hidden plumbing leak from the adjacent bathroom. The damp wall provides the moisture mould needs to grow, and the lack of airflow behind the wardrobe creates the perfect environment.

For a DIY approach, first move the furniture to dry the area completely. Scrub the mould off the wall with a mixture of detergent and water; avoid bleach as it doesn't kill the roots and can worsen indoor air quality. Once clean and dry, address the moisture source. For condensation on a cold wall, improving airflow is key. Consider leaving a gap between the wardrobe and the wall. For a potential leak from the bathroom, inspect seals around showers and sinks. A dehumidifier can help significantly in reducing ambient humidity.

Regarding your AC, it is likely spreading the spores. Mould spores become airborne when disturbed. While your AC filter may catch some, it can circulate them throughout the home. Have the AC system inspected and cleaned by a professional to prevent ongoing distribution, especially since your children are symptomatic.

Given the symptoms and the concealed nature of the growth, a professional inspection is strongly recommended. DIY cleaning removes visible mould but doesn't address the extent of hidden growth inside the wall or the specific species present, which is important for health concerns. A certified inspector can use moisture meters and thermal imaging to find the moisture source and take air and surface samples for lab analysis to identify the mould type and confirm the air quality is safe.
