How to treat black mould in Dubai villa for health?« Back to Previous Page

Black mould in Dubai villas is a health concern, particularly for children and those with respiratory sensitivities. The high humidity, especially during the summer and recent humid seasons, combined with year-round AC use creating cold surfaces for condensation, creates ideal conditions for mould growth behind furniture and curtains.

For a small patch, a solution of white vinegar or a diluted bleach mixture can be used for cleaning. However, the visible patch is often just the fruiting body; the root system can penetrate porous materials like drywall or plaster. Scrubbing without addressing the root cause and the hidden growth will result in it returning quickly.

The primary goal is to identify and eliminate the moisture source. In Al Barsha villas, common causes include leaking AC drain lines, condensation from poorly insulated external walls (especially behind curtains), or internal plumbing leaks. A professional inspection is recommended to pinpoint the exact source, as treating the symptom without fixing the moisture issue is ineffective.

For health safety during remediation, the area should be isolated, and family members should avoid the space. While cleaning, wear an N95 mask and gloves. After removal, improve ventilation and consider using a dehumidifier to maintain indoor humidity below 60%, as per Dubai Municipality guidelines for healthy indoor air.

If the mould covers a large area (typically more than one square meter) or if health symptoms persist, professional remediation is advised. Reputable providers use containment procedures to prevent spore dispersal and employ HEPA filtration. They should also be able to conduct post-remediation verification testing to confirm the mould and its allergens have been effectively removed.
