Excessive moisture on or around your windows is cause for concern because it can lead to mold or mildew growth which is detrimental to your health. Window condensation can be remedied with the right tools and home investments. Moyes Glass wants to help improve the lifespan of your windows and keep common window condensation at bay. This blog contains some common causes of window condensation and tips on what you can do to solve them.
Causes Of Window Condensation

Condensation usually occurs when hot and cold air mix together. This is why when you have a cold drink on a hot day, the outside of the glass starts to have water condensation beads. This same process contributes to window condensation, but window condensation can occur even on cooler days.
If your home is often humid on the inside then condensation is likely to occur. Since windows are not insulated like the rest of the home, they are more prone to window condensation. The warm inside air and cold outside air stay trapped on either side and can create water droplets or frost. While it may seem impossible to keep your home at a regulated temperature and prevent window condensation, that is not the case. Below are some solutions to keep your home free of excess condensation.
1- Air Out Windows
Allowing air to circulate and mix with the outside air will help prevent condensation. Opening the windows a crack from time to time will help prevent such drastic temperature differences around your windows.
If you are not wanting to let the cooler outdoor air enter your home, running a small fan can accomplish the same air circulation.
2- Replace Old Windows
Finding condensation on your windows may be a reason to seek window replacement. Often times old windows have cracks or are no longer sealed properly and allow air or moisture to become trapped or can not regulate the changes effectively. Double-pane windows are less prone to window condensation because there is an extra layer for air to pass through. The adjustment of temperatures is less drastic with properly insulated window solutions of double-paned windows.
3- Adjust Your Home Temperature
While begin comfortable in your home is important, preventing window condensation may be as easy as lowering the temperature in your home by a few degrees. Humidity inside your home is also a main contributing factor to condensation. Lowering the temperature or purchasing a dehumidifier will help to reduce the likelihood of condensation on your windows.
For areas where you use hot water, like the shower, kitchen, or even laundry room, avoiding condensation may look like running the hot water for less time. The steam and humidity from rising hot water will cause condensation on your windows. If this is where you see the most window condensation, don’t stress, just lower the temperature of the water, or crack the window during your shower to let the exterior air in.
4- Weatherize The Windows
When condensation is bothersome on the exterior of your windows, you can apply some weatherizing solutions to keep moisture from forming. Water repellent, caulking gaps, or improving the seal can all stop snow and rain from collecting. Taking this step to prevent window condensation can prevent moisture from entering your home or getting trapped and leading to mold growth.
5- Increase Ventilation In Your Home
Eliminating window condensation or a musty smell in your home can be done by increasing ventilation in your home. Allowing the windows to be open at some point in the day, including ceiling fans or household fans, or turning the heat down when you are not home, can help more clean air circulate through your home and prevent mold growth. Similar to airing your windows out, allowing exterior air to mix with interior air will decrease the likelihood of such drastic temperatures between the sides of the windows.
