How to Stop Condensation on Windows
Condensation is a problem that many homes have to deal with. So, how do you prevent condensation on your windows? Well, the good part about this is there are several things that you can do to fix the problem. In some cases, you may need to replace or repair the glass and windows. In others, you can make a few small changes to remedy the situation.
Whatever the case, this is an issue that needs to be resolved as quickly as possible to prevent moisture buildup, the appearance of mold, mildew, wood rot, or other similar such problems around the house. Below are several quick, DIY fixes that will help you get rid of window condensation forever.
Is Condensation on Windows Bad?
No, window condensation is not cause for alarm, especially if it’s temporary. However, excessive window condensation can be bad in some cases. It can even cause damage to your home. Condensation can rot wood, ruin plaster and cause excess moisture in your home. This creates interior condensation, which affects your entire house, not just your windows.
Condensation on the Outside of Windows
When window glass is colder than the dew point outside, condensation is likely to occur on the exterior of the window. Condensation, or dew, occurs naturally when the air becomes completely saturated with water.
Condensation on the Inside of House Windows
Interior window condensation is caused by excessive moisture inside the house. This happens in the winter months when warm air inside the house condenses on the cold windows.
Condensation occurs on the inside of windows every time there is water vapor that turns into a liquid. If the surface of the glass inside your windows is below the dew-point of the surrounding air, it will begin to fog and condense.
How to Absorb Condensation from Windows
One of the best ways of removing moisture from your home is to increase the ventilation around the house and windows. When weather permits, the quickest and cheapest way is opening some doors and windows, preferably at the opposite sides of the house.
Whether it’s with ceiling or vertical fans, these will not only help reduce moisture but also better distribute the hot air around the home. Make sure to turn on these fans or open some windows when you’re showering. The same thing can be said for when you’re cooking.
Use a Dehumidifier
To keep moisture off of windows, it’s a good idea to place a dehumidifier near the windows where condensation tends to form. Dehumidifiers remove moisture from the air and keep moisture off your windows. Also, running the shower can make the house extremely humid. Try running your bathroom fan when showering.
How to Keep Windows from Fogging Up
Weather-strip your Windows
Another quick and effective way of preventing window fogging is by stopping cold air from blowing inside your home in the winter. To do this, the best way is to weather-strip them. Not only will this prevent condensation, but it will also save you on your energy bills.
Line Dry Your Clothes
A similar win-win situation as weather-stripping is to line dry your clothes outside. This will save you on energy bills when using a drier and will prevent moisture buildup. If you dry your clothes indoors, try keeping a window open.
Move Your Houseplants Outside
The more plants you have indoors, the higher the humidity level. Sometimes, simply moving these houseplants outside will be enough to eliminate condensation.
When Should You Repair or Replace Your Windows?
Sometimes, despite whatever quick fixes you try, nothing seems to work, and your windows are still collecting condensation. In some cases, condensation on the inside of windows is the result of a failing windowpane seal. When this happens, cool air will make its way inside double-paned windows and attract condensation.
At other times, your windows might be too old and drafty. Installing storm windows may help prevent your windows from getting cold. Another way of doing it is by replacing your old single-pane windows with double or even triple glazing. While this may be more expensive than the other examples above, over time, this investment will pay for itself in the form of lower energy bills.
