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

The AC in my bedroom closet has been leaking a little for a couple of months, and now I’m seeing black spots spreading on the back wall and on some of my shoes. I wiped it with vinegar but it came back worse after a week. Is this something I can tackle myself with a stronger cleaner, or do I need to call a professional company to get rid of it for good?

Based on your description, this is a classic case of mold growth driven by a persistent moisture source, specifically the AC condensate leak. The fact that the mold returned more aggressively after a DIY cleaning attempt with vinegar is a critical indicator that this is not a surface-level issue. Vinegar is often insufficient as it does not address the root moisture problem or penetrate porous materials to kill the hyphae (the root-like structures of the mold).

In the UAE's climate, with its extreme humidity and year-round reliance on AC systems, such leaks are a primary cause of indoor mold. The constant cycle of condensation provides the perfect environment for colonies to thrive deep within building materials, like drywall and the backing of your closet. The black spots are likely Cladosporium or Stachybotrys (black mold), which require professional assessment.

Attempting a stronger cleaner yourself is not advisable. Agitating the colony with improper chemicals can aerosolize toxic spores, spreading the contamination to other areas of your home and posing a significant inhalation risk. Furthermore, Dubai Municipality has guidelines for environmental health and mold remediation that professionals are trained to follow, ensuring the problem is contained and removed safely without violating any local regulations.

The required course of action is a professional inspection and remediation. The leak must be repaired by an AC technician first. Then, a certified mold inspector will conduct air and surface sampling to identify the spore types and concentration levels. Based on this, a remediation plan is created, which includes containment of the area, HEPA filtration, and the safe removal and disposal of contaminated porous materials (like the affected wall section and shoes).

For a definitive solution and to ensure your indoor air quality is restored, I strongly recommend you contact a professional company. Saniservice specializes in this exact scenario.
