What is causing musty smell near windows in apartment?« Back to Previous Page

Based on your description, that persistent musty odor near your floor-to-ceiling windows in Marina is a major red flag. In our humid UAE climate, the most likely culprit is concealed microbial growth, specifically mold, developing due to condensation.

Those large windows, while beautiful, are thermal bridges. The intense outdoor heat transfers through the aluminum frames and glass, cooling the interior surface. When our humid air contacts these cooler surfaces, it condenses, creating a constant damp environment. This moisture gets absorbed into the drywall, insulation, and even the window seals themselves, providing the perfect food source for mold spores that are always present in the air.

The fact that the smell is strongest near the vents is also highly significant. It suggests your AC system might be drawing in moist air from these damp cavities and distributing the spores and microbial volatile organic compounds (mVOCs) – which cause the musty smell – throughout your living area. This would directly explain your kids' increased coughing, as they are breathing in these irritants.

You absolutely need a professional inspection. DIY checks are insufficient as the growth is likely hidden within the wall cavity or behind the skirting boards. We use borescopes and moisture meters to pinpoint the exact source and extent of the contamination without destructive investigation initially. Proper remediation is critical, not just surface cleaning, to protect your family's health.
