How to permanently fix dampness and mold in bedroom?« Back to Previous Page

The black speckles on your wardrobe wall in Jumeirah point to a persistent dampness issue, common here due to our high humidity and constant AC use. A constantly running dehumidifier only treats the symptom, not the source. The dampness is likely from a hidden leak or, more commonly in villas, condensation caused by a thermal bridge.

Start by inspecting the outside wall for cracks in the render or compromised sealant around windows that could let in humid air. Check the AC unit serving that room; a clogged drain line or an oversized unit that short-cycles can cause excessive condensation inside the walls. The wall behind the wardrobe is likely significantly colder than the room air, causing moisture to condense on it unseen.

For a permanent fix, you must identify the exact moisture source. This requires a professional inspection with a thermal imaging camera to pinpoint cold spots (thermal bridges) and a moisture meter to quantify the dampness within the wall cavity. Simply wiping the mould away will fail, as it will return until the underlying humidity problem is resolved.

In Dubai, remediation involves fixing the leak or insulating the cold wall to prevent condensation, followed by professional mould removal to address any growth inside the cavity. A company with its own microbiology lab can test to confirm the species and verify the cleanup was successful through post-remediation testing, ensuring it doesn’t return.
