Is this black mold dangerous and should I test it?« Back to Previous Page

We've lived here for 2 years and just noticed a spreading black patch behind our bedroom wardrobe. It's been incredibly humid in Dubai Marina this winter and I've been waking up with a stuffy nose, itchy eyes, and a headache that won't go away. I'm worried it's making me sick. **How dangerous is this kind of mold and should I get a professional test done or can I clean it myself with bleach?**

Based on your description, the situation you are describing is a serious concern that warrants immediate professional attention. The black patch spreading behind your wardrobe, combined with your persistent respiratory symptoms (stuffy nose, itchy eyes, headaches), strongly indicates a significant mold infestation that is very likely affecting your indoor air quality and health.

The term "black mold" often refers to Stachybotrys chartarum, a toxigenic mold species that can produce mycotoxins. In the humid, enclosed space behind furniture, it thrives. The climate in Dubai Marina, especially with the recent high humidity levels and the constant use of air conditioning, creates massive condensation issues. This trapped moisture against cooler walls is a perfect breeding ground for such mold. Attempting to clean it yourself with bleach is highly inadvisable. Bleach is ineffective on porous surfaces like drywall, as it only bleaches the surface color without addressing the root structure of the mold. It can also aggravate the problem by releasing a high volume of spores and harmful fumes into your living space during agitation, potentially worsening your symptoms.

A professional inspection is absolutely necessary. Our certified inspectors use tools like moisture meters, thermal imaging cameras, and air and surface sampling to determine the exact species and the full extent of the contamination, which is often far greater than what is visible. This testing is crucial to develop a safe and effective remediation protocol, as mandated by UAE health and safety guidelines for proper biocontainment and removal.

For your health and the integrity of your property, I strongly recommend you do not disturb the area and seek a professional assessment immediately.
