How to permanently stop black mold around windows?« Back to Previous Page

Black mold around windows is a common issue in Dubai due to the high humidity and constant temperature shifts between our hot outdoor climate and cold, air-conditioned interiors. This creates significant condensation, which is the primary fuel for mold growth. Simply wiping it away treats the symptom, not the cause.

The most effective long-term solution is to manage the moisture. First, improve ventilation in the room by opening windows daily when the outdoor humidity is lower, typically in the early morning or evening. Use a squeegee to wipe down condensation from windows and window frames every morning. Ensure your AC unit is set to a reasonable temperature; excessively cold settings increase condensation. Check that window seals are intact, as failed seals allow humid air to seep in and condense on the colder glass.

For persistent cases, the underlying issue is often high relative humidity within the room itself. A professional inspection can identify these hidden moisture sources and assess the extent of the growth. In many older Jumeirah buildings, the problem is systemic. Remediation involves safely removing the established mold colonies—which are likely deeper than the surface—and then applying preventive treatments. The final, critical step is a post-remediation verification test from an independent lab to confirm the spore count has been returned to a normal level, ensuring the solution is truly effective and your indoor air quality is safe.
