Is closet mold a DIY fix or professional job?« Back to Previous Page

The presence of black mould in a closet on an interior wall, especially with high humidity, is a sign of a persistent moisture issue that needs to be addressed at its source. In Dubai's climate, this is often due to condensation from AC ducts running inside the wall or a lack of ventilation.

For a small patch (under one square foot), a DIY approach can be attempted. Use a vinegar solution (1:1 with water) or a dedicated mould cleaner, not bleach, as bleach only removes surface discoloration and does not kill the roots. You must wear an N95 mask and gloves. However, this is only a temporary fix if the moisture source remains.

For anything larger, a recurring issue, or if the mould is on drywall, a professional inspection is strongly recommended. The mould you see is often just the surface growth; the underlying problem inside the wall cavity could be far more extensive. A certified inspector will use moisture meters and thermal imaging to find the exact source of the water intrusion and take air/surface samples for lab analysis to confirm the mould type. Saniservice’s diagnostic process is designed to identify these hidden problems to ensure a proper, long-term solution, not just a surface clean.

Given your description of high room humidity, the issue is likely systemic. Call 800-MOLDS for a diagnostic assessment to identify the root cause and get a scientifically-backed remediation plan.
