Can I remove this mold myself or call a professional?« Back to Previous Page

We've lived here for 2 years and just noticed a bunch of black spots spreading in the corner of our master bedroom closet, behind all the clothes. It's on the wall that faces the outside, and it's been worse since the humidity spiked last week. Is this something I can tackle myself with vinegar and bleach, or do I need to call in one of those mold remediation companies I see advertised?

Based on your description, this is a textbook case of a mold issue exacerbated by the Dubai climate. The location on an exterior wall, combined with the recent spike in humidity, strongly suggests a condensation problem. This is a common occurrence here where cool air from year-round AC meets the warm, humid air infiltrating from outside, creating the perfect environment for mold growth behind furniture and in closets.

While a small, surface-level patch might be addressed with a DIY solution like diluted vinegar, your situation requires a more professional approach for several reasons. The mold is behind clothing, indicating a potential for spore dispersal during cleaning. More critically, the location on an exterior wall raises the possibility of a more serious issue, such as a hidden leak in the building envelope or insufficient insulation, which a surface clean will not fix.

In the UAE, proper mold remediation is not just about cleaning; it's about identifying and resolving the underlying moisture source to prevent recurrence, which is a core requirement of local building hygiene standards. Disturbing the colony without proper containment and air filtration can inadvertently spread microscopic spores throughout your bedroom and HVAC system.

For a case like this, I strongly recommend a professional inspection. A certified technician from a company like Saniservice can conduct moisture mapping and thermal imaging to pinpoint the exact moisture source, assess the extent of the growth, and provide a protocol for safe, effective remediation that includes containment, air scrubbing, and addressing the root cause. For a proper assessment and to discuss a solution, please call 800-MOLDS (800-66537) or email hello@saniservice.com.
