Black mold in closet: DIY or call professional in Dubai?« Back to Previous Page

Good question. This is a very common issue in Dubai, especially on exterior walls where thermal bridging and condensation can occur. Let's break it down.

First, that black spot is almost certainly mold, feeding off the cellulose in the drywall and the organic material (dust, skin cells) on your clothes. The high humidity we've been experiencing acts as the perfect catalyst.

Regarding DIY: While bleach and vinegar are common suggestions, I strongly advise against them for a few technical reasons. Bleach is mostly water. The chlorine evaporates quickly, only bleaching the mold on the surface while the water soaks into the porous wallboard, feeding the root system (hyphae) deeper within. This makes the problem worse. Vinegar can kill some surface mold but is ineffective on porous materials and won't address the root cause.

In the UAE, the primary concern isn't just cleaning; it's identifying and resolving the moisture source. Is it condensation from the AC system? A tiny leak in the external wall sealant? Poor insulation? Without a professional inspection, including moisture meters and thermal imaging, you're just treating the symptom.

For a small, surface-level area (less than 1 square meter), you might manage it by carefully cleaning with a HEPA vacuum and a dedicated EPA-approved fungicide, not household cleaners. However, given its location on an exterior wall and its recurring nature, this indicates a persistent moisture issue.

My professional recommendation is to call for an inspection. We need to identify the exact moisture source to prevent it from returning after any cleanup. Improper handling can also aerosolize spores, spreading the contamination to other areas of your home.
