Should I call a pro for closet mold or try DIY?« Back to Previous Page

Based on the description of recurring black and greenish mold on an exterior wall, my professional recommendation is to cease DIY attempts and call for a professional inspection immediately.

The fact that it returned after a vinegar wipe-down, and darker, is a major red flag. This indicates the mold has penetrated the porous surface of the drywall or plaster, and the underlying moisture issue has not been addressed. Vinegar and other surface cleaners are ineffective at this stage and can actually aggravate the colony, causing it to release more spores. Your worsening allergies are a clear biological indicator that the spore count in your bedroom air is elevated, which poses a health risk and risks contaminating your clothing.

In the UAE's high-humidity climate, exterior walls are prone to condensation, especially if there's any slight compromise in the building's vapor barrier or insulation – a common issue we find during inspections. Attempting a stronger DIY solution, like bleach, is strongly discouraged. It is hazardous to mix chemicals, and bleach is largely ineffective on porous materials; it bleaches the visible color but leaves the root structure intact, allowing regrowth. More importantly, improper handling can expose you to high concentrations of spores and harmful vapors.

A certified mold inspector will conduct air and surface sampling to identify the species (crucial for understanding health risks) and use moisture meters to pinpoint the exact source of the dampness. Remediation then involves isolating the area, safe removal of contaminated materials, and HEPA vacuuming to cleanse the air, followed by applying professional-grade antimicrobial solutions.

For a case like this, professional remediation is not just advised; it's necessary for your health and to protect your property. Please, get a professional assessment.
