How to remove and prevent black mold from windows?« Back to Previous Page

Black mold on windows is a common issue in Dubai villas due to high humidity and constant AC use, which creates condensation. The coughing you're noticing could certainly be related, as these molds release spores that irritate the respiratory system, particularly in children.

For cleaning, wear an N95 mask and gloves. Use a solution of one part distilled white vinegar to one part water, or a dedicated mold remover, and scrub the affected area with a stiff brush. Avoid bleach, as it only removes the surface color and doesn't kill the root structure embedded in porous surfaces like drywall or wood. After cleaning, ensure the area is thoroughly dried.

Preventing its return requires controlling the humidity that allows it to grow. First, improve ventilation by opening windows when outdoor humidity is lower, typically in the early morning or evening. Use a dehumidifier in the room, aiming to keep relative humidity below 60%. Wipe down window frames and glass daily to remove condensation, especially after the AC has been running. Check that your AC unit is properly sized and functioning; an overworked unit can cool the glass too quickly, creating more condensation. Ensure window seals are intact to prevent humid outdoor air from seeping in.

For a persistent problem, a professional inspection can identify hidden moisture sources within the walls or from AC drain lines. In many cases, the mold on the window is just the visible part of a larger issue. A science-driven assessment with air and surface sampling can identify the specific mold type and spore concentration in the room's air, which is crucial for understanding the health risk to your family and ensuring the remediation is complete.
