How to Remove and Prevent Window Condensation?

Window condensation might be a real pain. Do you have problems with your windows fogging and sweating on the inside as the weather changes? If this describes you, know that you're not alone. Condensation is the name for this occurrence. It happens more often than you might imagine. 

Condensation on windows can be aggravating, and in rare situations, it can even cause damage to your home. Excess moisture in your home, which produces interior condensation, can harm your entire home, rot wood moulding and damage plaster.

Condensation Inside Window: What Are the Causes and How to Remove It?

Excessive moisture in the house causes condensation inside the window, which is most common in winter when warm air within the house condenses on the cold windows. 

As per EPA (Environmental Protection Agency), the relative humidity should never exceed 60%. During all seasons you should aim for a percentage of 30 to 50 percent.

Here are helpful tips as for how to remove condensation on the inside of the window:

  1. Turning Humidifier down. Because the humidifier on the lower setting releases less moisture into the air, condensation should be reduced.
  2. Using Fans. When you cook or shower, turn on the fans in your bathroom and kitchen for about 15 minutes. 
  3. Using Ceiling fans. Circulating air can also aid in the reduction of condensation on the inside window. So, even in the winter, turn on your ceiling fans. The fans should spin in a clockwise direction to force warm air from the ceiling down to the floor.
  4. Opening windows. You can open your windows if it isn't too cold outside. This will allow some of the warm, damp air in the house to escape.
  5. Raising the thermostat. You can boost the temperature of your house slightly to raise the warmth of your windows. 
  6. Relocating your plants. Plants leak moisture into the air, moving them to a new location can help prevent condensation.
  7. Dehumidifier. Investing in a dehumidifier is a simple approach to get rid of excess moisture in your home. 
  8. Keeping windows out of coverings. When drapes or shades are drawn down, condensation is more prone to form. Draw your window coverings to keep the heat from accumulating on your window pane. 
  9. No firewood inside. To help regulate humidity, store firewood outside if you have a fireplace.

Condensation on the Outside of the Window: What Are the Causes and How to Stop It?

Condensation forms on the outside of your windows when the temperature of the glass's outer surface dips below the dew point of the air. When outdoor humidity levels are higher, such as in spring, summer and fall, when cool nights follow warm days, this form of condensation in the window is more likely to occur. 

What are the window condensation solutions?

  1. Patience. Condensation on the outside of windows is fairly prevalent because it is seasonal and climate-related. It's not a sign of a problem with your windows or the humidity level in your house. Simply wait for the sun to shine and evaporate all of the moisture.
  2. Water repellent. If the condensation really bothers you, try using a water repellent on the outside of your windows – you might already have some in your garage. Water repellant is routinely applied to car windshields to aid visibility in rainy conditions. It can be used to prevent condensation on house windows in the same way.

Having a window with seal failure can reduce your home's overall energy efficiency. It is very important to address the problem as soon as possible.
