How to treat and prevent black mold on bedroom wall?« Back to Previous Page

Based on your description of black speckles behind a wardrobe in a Marina apartment, you are almost certainly dealing with a mold colony, likely triggered by the recent increase in humidity. The constant AC operation could be a sign the unit is struggling to dehumidify properly, which is a common issue in our coastal climate.

Do not attempt to treat this yourself. Disturbing the colony by cleaning it can release a massive amount of spores into your bedroom air, potentially causing health issues and spreading the contamination. The first and only step you should take is to have a professional inspection. We need to identify the mold species (some are more hazardous than others) and, most critically, find the source of the moisture. It could be a leaking pipe in the wall, condensation from the AC drain line, or insufficient ventilation behind the wardrobe.

In Dubai, remediation must comply with strict guidelines to ensure spores are contained and removed safely, not just wiped down. For a proper assessment and a certified remediation plan, please call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com. We use thermal imaging and borescopes to find hidden moisture and mold without unnecessary demolition. Preventing its return involves fixing the water source, ensuring your AC is serviced and draining correctly, and improving air circulation behind furniture – something we can advise on after the inspection.
