How to find moisture source and inspect for mold?« Back to Previous Page

As a certified mold inspector in Dubai, what you're describing is a classic symptom of our local climate. The extreme outdoor humidity (often exceeding 90%) combined with year-round AC use creates significant potential for condensation and hidden moisture buildup, especially in enclosed, poorly ventilated spaces like closets.

The first step is a systematic moisture investigation. You must move everything out of the closet for a thorough visual assessment. The black speckles are a strong visual indicator of active mold growth. Using a digital hygrometer, measure the relative humidity and temperature inside the closet and compare it to the main bedroom. A difference of more than 5-10% RH indicates a serious lack of air circulation. A non-invasive moisture meter is then used to take readings of the walls, floor, and ceiling in that corner. This will quantify the moisture content within the building materials and help pinpoint the exact source—whether it's condensation from the temperature differential, a tiny plumbing leak from an adjacent bathroom, or even a minor infiltration from a poorly sealed window or external wall, which is not uncommon in older villas.

A proper inspection, as per UAE standards and guidelines, goes beyond this. It involves thermal imaging to identify hidden cold spots (thermal bridges) where condensation forms unseen, and air and surface sampling to identify the species of mold and its concentration. This data is critical for designing an effective remediation protocol.

Given the conditions you've described, this requires professional diagnosis. DIY attempts often disturb the colony, spreading spores to other areas. Our team at Saniservice uses this exact technical process to locate the moisture source, contain the affected area, and provide a definitive report and solution. I strongly recommend you call us for a comprehensive assessment at 800-MOLDS (800-66537) or email hello@saniservice.com to prevent it from spreading further.
