How to remove mold and who to call in Dubai?« Back to Previous Page

Black mould growth behind furniture on a cold wall is a common issue in Dubai villas, often caused by condensation from the temperature difference between the air-conditioned room and the exterior heat. The damp, cold surface you describe confirms this.

For removal, start by addressing the moisture source. Improve ventilation in the room immediately; running a dehumidifier can help measurably reduce humidity levels. To clean the visible mould, wear an N95 mask and gloves. Scrub the area with a microfiber cloth and a solution of detergent and water. Avoid bleach, as it only lightens the stain and does not kill the root structure, often causing regrowth.

However, scrubbing the surface is a temporary fix. The wall feeling cold suggests possible insulation issues, and the mould's presence indicates potential hidden growth inside the wall cavity. This is a serious case requiring professional assessment.

You should call a certified mould inspection and testing company. In Dubai, look for a provider that uses a moisture meter and thermal imaging camera to locate dampness and hidden mould behind walls without destructive probing. The most critical step is that they should conduct air and surface sampling, with the analysis sent to an independent, accredited microbiology lab. This lab report is essential—it identifies the mould species and spore concentration levels, which determines the proper remediation protocol and verifies the work was done correctly.

For a villa, a whole-property assessment is recommended to check other common problem areas like AC units and ductwork, which can spread spores throughout the home. Proper remediation involves containing the area, removing contaminated materials, and applying antimicrobial solutions, followed by post-remediation verification testing to ensure the problem is resolved.
