Black mold found behind wardrobe, DIY or call pro?« Back to Previous Page

The black mould behind your wardrobe is a common issue in Dubai homes, often stemming from condensation where walls meet cold AC ducts or from hidden humidity leaks. Bleach is not recommended; it's mostly water and can worsen the problem by feeding residual spores without addressing the root cause. For a small patch (under one square meter), scrubbing with a vinegar solution or a dedicated mould cleaner can be effective, but you must identify and fix the moisture source—often a small leak or insufficient ventilation.

However, given the location (behind furniture, likely undisturbed for two years) and the fact it's causing health symptoms, a professional inspection is strongly advised. Hidden mould can spread inside wall cavities, and improper DIY dispersal can increase spore concentration in your air. Prolonged exposure, even to non-toxic moulds, can irritate respiratory systems, particularly in children.

Reputable remediation companies in Dubai should follow guidelines like the IICRC S520 standard. They will contain the area, use HEPA filtration to clean the air, and most importantly, use moisture meters and thermal imaging to find the exact humidity source. For verification, some firms, including those with in-house microbiology labs, can take air samples before and after to confirm spore counts have returned to safe levels. The goal is to fix the environment so it doesn't come back.
