Window Condensation Problems in Houston: Humidity Causes and Fixes

What Makes Houston Windows Sweat In The First Place

Houston humidity gives windows a workout, and condensation is one of the first signs that moisture is winning.

Condensation on the inside of the glass usually points to indoor humidity that is too high or a surface that is too cold.

This type of condensation is often linked to daily living, not a broken window, especially in kitchens, bathrooms, and laundry areas.

High indoor humidity from cooking, showers, and laundry, poor ventilation in tight rooms, thermostat settings that keep the glass very cold, air leaks around the frame, and blinds or curtains that trap humid air against the window.
