Black spots in damp closet - DIY fix or call management?« Back to Previous Page

This is likely mold, given the dampness and Dubai's high humidity. The wall facing outside is a common problem area where warm, moist outdoor air meets the cooler, air-conditioned interior wall, causing condensation.

For a small area you can manage it yourself. First, wear an N95 mask and gloves. Wipe the area with a diluted white vinegar solution (1 part vinegar to 1 part water) or a dedicated mold remover, then dry it thoroughly with a fan. Discard any moldy porous items like cardboard boxes. The key is not just cleaning but stopping the moisture source. Check for a leaking pipe or AC condensation drain issue in that wall cavity. A dehumidifier in the room can help manage ambient moisture.

If the area is larger than one square meter, the dampness persists after cleaning, or you smell a musty odor, call building management. In Dubai, landlords are typically responsible for fixing structural issues causing dampness, like inadequate exterior waterproofing or faulty plumbing. A professional inspection can identify the exact moisture source, which is often hidden. They can also perform air or surface sampling to confirm the mold type, as some species require more stringent containment during remediation.
