Window condensation can be a natural occurrence. Typically, it appears first on windows because glass surfaces have the lowest temperatures compared to other interior surfaces in the home. Condensation can be viewed as 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 the result of a higher air moisture content contacting lower temperatures on the glass. The higher the indoor humidity and the lower the outside window temperature, the more condensation can occur.
Living in Florida, temperatures are normally warmer outside and cool and air conditioned inside, so many Florida homeowners experience exterior window condensation year-round and interior window condensation during the winter months.
There’s no need to worry if you see a little condensation in the corners of your windows every now and them. Usually it doesn’t last long at all, so there is little risk for mold. Excessive condensation, however, is when there is so much condensation built up on your windows, the water begins to run down and pool in the sills, or runs off the windows and stains the woodwork or walls below.
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.
Daily activity such has showers, cooking, using dishwashers, washing machines, and dryers will produce water vapor into your home, raising indoor temperature resulting in condensation on your windows. Condensation is directly related to the amount of water vapor and humidity inside the home.
Modern houses are built in a way that keeps homes more air-tight. This is due to the energy crisis in the 1970’s, where there was a huge push to build homes in a more energy efficient way. Therefore, our homes are more insulated, and the by product is that moisture is also kept inside.
It is very important that you prevent excessive buildup of water vapor and humidity so that your home does not trap harmful moisture levels inside. Luckily, there are a few steps you can take to mitigate the accumulation of humidity inside your home.
- 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 sashes for smooth, adequate operation. Add integrated window ventilators and air exchange devices if necessary.
- Regularly use exhaust fans especially when showering.
- Install and use a dehumidifier. Use Ceiling fans to circulate air.
- Open windows or doors whenever practical or possible to allow interior moisture to escape.
