Black mold in closet: DIY or call a professional?« Back to Previous Page

Based on your description, this is a common issue in Dubai due to our high humidity levels and the constant cycling of air conditioning, which can create significant condensation, especially in enclosed, poorly ventilated spaces like closets on interior walls. Storing damp clothing is a frequent catalyst.

For a small, isolated area (less than 10 square feet), a careful DIY approach may be feasible. First, wear an N95 mask, gloves, and eye protection. Isolate the area by sealing the closet off from the room with plastic sheeting. The moldy drywall surface can be cleaned with a solution of detergent and water (never mix bleach with ammonia). Completely dry the area using fans and a dehumidifier. The root cause, however, is excess moisture. You must identify and rectify this; it could be the initial damp storage, but more likely it's due to condensation from the AC system or a lack of ventilation.

However, given that the mold is on an interior wall, there is a non-zero risk that the growth has penetrated deeper into the drywall or even the insulation cavity, which is impossible to properly address without professional equipment and techniques. Disturbing it incorrectly can aerosolize spores and contaminate your entire bedroom.

For a confirmed and recurring issue like this, a professional inspection is strongly recommended. We use moisture meters and thermal imaging cameras to identify the exact moisture source and borescopes to inspect inside walls. This is crucial for an effective, permanent solution. Remediation involves advanced containment, HEPA filtration, and antimicrobial treatment to ensure the mold is eradicated, not just superficially cleaned.

For a proper assessment and to discuss a permanent remediation plan, I advise you to call our specialists at 800-MOLDS (800-66537) or email hello@saniservice.com. Saniservice is fully compliant with Dubai Municipality and HAAD standards for environmental hygiene.
