How to permanently remove mold in a high-rise bedroom?« Back to Previous Page

Bleach only removes surface discoloration but doesn't address the root cause, which is why it returns. In Dubai's high humidity, especially in sealed high-rises with constant AC, condensation forms on cold surfaces like exterior walls behind furniture. This moisture allows mold to regrow from the spores embedded in the wall material.

First, move the headboard and any furniture away from the wall to improve air circulation. The AC unit should be checked; if it's not dehumidifying properly or its condensate drain line is clogged, it can saturate the wall with moisture. In the Marina, this is a common issue due to the sea air and building envelope pressures.

The only permanent solution is to identify and eliminate the moisture source. For a recurring case like this, a professional inspection is recommended to pinpoint the exact cause, which could be a minor condensation issue or something more significant like a tiny leak within the wall cavity. They can also assess if the mold growth is extensive enough to require professional remediation, which involves removing contaminated materials like drywall or insulation and treating the area with specialized antimicrobial agents.

To prevent recurrence, after the source is fixed, repaint the affected area with a high-quality, mold-inhibiting primer and paint. Maintain indoor humidity below 60% using a dehumidifier if necessary, and ensure your AC servicer cleans the unit and checks its drainage function at least twice a year.
