How to treat and prevent mold in a humid sea-facing bedroom?« Back to Previous Page

The black speckles are likely mold, a common issue in sea-facing Jumeirah properties where salt-laden air and high humidity create persistent dampness. Your AC removes ambient moisture, but it cannot address condensation trapped behind furniture or within poorly insulated external walls.

For the existing mold, wearing an N95 mask and gloves, clean the area with a solution of white vinegar or a dedicated mold remover. Never use bleach, as it only discolors the surface and does not kill the roots. For porous surfaces like drywall, the affected section may need to be cut out and replaced if the growth is extensive.

Preventing recurrence requires addressing the moisture source. Move the wardrobe at least two inches away from the wall to allow air circulation. Wipe down the wall and the back of the furniture regularly to remove condensation. Inspect the external wall for cracks or failing sealant that may be allowing moisture ingress from the sea air; these will need professional sealing.

For a persistent problem, a professional inspection is recommended. They use thermal imaging to pinpoint hidden condensation and moisture meters to quantify the issue, which is often necessary for sea-facing villas. The most effective long-term solution may involve improving the wall’s insulation or installing a small dehumidifier in that room to work in tandem with your AC system.
