How to safely clean black mold in Dubai bedroom?« 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 store our winter clothes. It’s on the wall that faces the outside, and it feels damp. With the high humidity lately in Dubai, I’m really worried it’s spreading. What’s the most effective way to clean this safely and who should I contact in Dubai to check if there’s a bigger problem with the building?

Good morning. That's a very common issue we see here in Dubai, especially on exterior walls during the humid summer months. The dampness you feel suggests a potential condensation issue or, more seriously, a hidden water intrusion from the building envelope. Here’s what you need to know.

First, safety is paramount. That black patch could be Stachybotrys chartarum, a toxigenic mold. Do NOT just wipe it with bleach. This can agitate the spores, releasing them into your air and making the problem worse. For a small patch (less than 1 sq. ft), you can carefully clean it yourself. Wear an N95 mask, gloves, and eye protection. Use a solution of detergent and water, scrubbing gently. Never mix chemicals. However, the damp wall is the real concern—cleaning the surface mold without fixing the moisture source is a temporary fix.

Given the location on an exterior wall and the persistent dampness, this is likely a building-related issue. It could be failing sealants, capillary action from the slab, or a breach in the damp proof course. This requires a professional inspection. We use thermal imaging cameras and moisture meters to pinpoint the exact source of the moisture behind the wall, which is absolutely critical.

I strongly recommend you get a certified mold inspector to assess the situation. They can determine the extent of the growth and identify the root cause. For a proper assessment and a remediation plan if needed, you should contact a professional environmental company here in Dubai. You can reach our team for a thorough inspection at 800-MOLDS (800-66537) or via email at hello@saniservice.com. Don't let it spread, as it can affect your health and the integrity of your belongings in that closet.
