How to remove black mold from bedroom corner in Dubai?« Back to Previous Page

The black spots in your bedroom corner are a common issue in Dubai, often caused by thermal bridging. This is where the concrete slab meets the exterior wall, creating a cold spot that attracts condensation from our humid air, especially with year-round AC use. The dampness and mold will likely return unless you address this root cause.

Start by identifying the moisture source. Wipe the mold off with a microfiber cloth dampened with a diluted detergent solution (1 part detergent to 10 parts water). Never use bleach, as it only removes the colour and can push spores deeper into the porous paint and plaster. Dry the area thoroughly with a fan.

To prevent recurrence, you must stop the condensation. Increase air circulation in the corner with a small fan. Run a dehumidifier in the room, particularly during more humid winter months. For a more permanent fix, consider having an insulation specialist address the thermal bridge, which is the most effective long-term solution.

If the mold covers more than one square meter, has a musty odour, or returns quickly after cleaning, a professional inspection is recommended. In such cases, a certified company can use moisture meters and thermal imaging to pinpoint the exact cause and perform remediation that includes containment and air scrubbing to prevent cross-contamination, followed by lab testing to verify the space is clear.
