What Causes Window Condensation in Mandeville LA and How to Reduce It

How Humidity Drives Window Condensation In Mandeville LA

Inside condensation usually starts when normal household moisture, from showers, cooking, laundry, or even breathing, raises indoor humidity enough to hit the glass first.

A few factors show up again and again in local homes.

• Poor air circulation around windows, especially with curtains or furniture blocking airflow
• Window surfaces that get cold enough to fall below the dew point
• Air leaks around frames that let humid outside air seep in

Older windows are often the biggest culprit.

Homes with heavier shade, deep porches, or limited afternoon sun can also keep window surfaces cooler for longer, which raises the odds of condensation.

An experienced window replacement company can confirm the cause with a quick inspection.
