How to handle black mold in bedroom closet?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black mold in the corner of our master bedroom closet where we keep our shoes and bags. It's on the wall and seems worse since the humidity spiked last week. I'm worried it's spreading but don't know if it's something I can tackle with a store-bought spray or if I need to call a professional company to deal with it properly. What's the best way to handle mold in a bedroom closet here, and at what point is it a job for the pros?

That black patch is a common issue in Dubai closets, especially on exterior walls where condensation forms. The recent humidity spike likely provided the moisture it needs to thrive.

For a small patch (under one square foot), you can often handle it yourself. Wear an N95 mask and gloves. Scrub the area with a mixture of white vinegar or a dedicated mold remover, then dry it thoroughly with a fan. The critical step is fixing the moisture source. Ensure your AC is running adequately to control humidity, and leave some space between the wall and your stored items for air circulation.

If the mold returns quickly, covers a larger area, has a strong musty odor, or if you have respiratory sensitivities, it’s time for a professional inspection. In Dubai’s climate, hidden moisture behind walls or under floors is a frequent culprit. A proper assessment includes moisture mapping and often air or surface sampling to identify the mold type and concentration, which guides the correct remediation method. This scientific approach ensures it’s resolved at the source, not just cleaned superficially.
