How to properly inspect and fix recurring black mold?« 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 I'm worried the recent humidity made it worse. What's the best way to get a proper inspection to find the source of the moisture and make sure it doesn't come back after cleaning?

Based on your description, this is a classic case of exterior wall condensation exacerbated by Dubai's high humidity and constant air conditioning use. The patch in the closet is likely just the visible manifestation; the actual moisture source and potential hidden growth within the wall cavity require a professional inspection.

A proper inspection involves more than a visual check. Our certified mold assessors use a combination of thermal imaging cameras to identify cold spots and temperature differentials on the wall (thermal bridging), which are prime locations for condensation. We then use a borescope to invasively inspect inside the wall cavity for hidden mold growth and moisture meters to quantify the moisture content in the building materials, pinpointing the exact source. Air and surface sampling are often conducted to identify the specific mold species and spore concentration levels, which is crucial for determining the appropriate remediation protocol as per UAE standards.

Simply cleaning the visible patch will not solve the recurring problem. The root cause—the condensation—must be addressed. This often involves improving insulation on the cold wall, ensuring the AC system is properly balanced to reduce extreme temperature differences, and addressing ventilation in the closet. For a thorough inspection and a guaranteed solution to prevent recurrence, I strongly recommend calling our specialists at Saniservice. We can diagnose the exact cause and provide a remediation plan that includes addressing the moisture source.
