Window Condensation & Mold

Window condensation can be a natural occurrence. It can be a warning that excessive moisture is present and may cause structural deterioration and the possibility of mold growth.

• Condensation on the inside of a window is a result of a higher air moisture content contacting lower temperatures on the glass. The higher the interior humidity and the lower the outside window temperature, the more condensation can occur.
• Excessive interior humidity can lead to structural damage and health concerns if high moisture levels are sustained inside wall cavities. Wood rot, mold and mildew can result.
• Check all sash for smooth adequate operation. Add integrated window ventilators and air exchange deceives if necessary.
• Regularly use exhaust fans especially when showering.
• Install and use a dehumidifier. Use ceiling fans to circulate air.
• Open windows and doors whenever practical or possible to allow interior moisture to escape.
