Why Are My Windows Wet Inside? (Quick Answers)

You might see fog gathering on the window, especially in times of rainy days and mornings. It is fun to draw on the foggy window.

But it also becomes inconvenient when you cannot see the outside properly. Further damage can also occur due to the excess fog in the window.

Following below are tips and information regarding the windows and the reason behind them getting wet and the possible solution that would help you out.

Windows wet inside

Windows can get wet inside due to the fog and especially due to the change in the humidity. The temperature also has an impact on creating wet windows. Well, it is nothing but an accumulation of moisture on the window. You can get rid of accumulating moisture before it turns into a bigger problem.

Windows give protection against weather changes. During winter, you would not want the cold air to come inside the room and freeze you.

Similarly, during summer, the hot sunlight is also not welcomed inside the house. With the weather changes, the windows also avoid changing the temperature of the inside of the house.

In the winter

The wet window appears more during the winter season. You would find the window is covered with moisture all over.

Some may think it is due to the defects in the windows. Well, it is not the case. This is the result of the weather change and nothing more than that.


The wet windows mainly appear due to the humidity of the surrounding. During winter the outside becomes filled with cold air.

Meanwhile, the inside of the house is kept warm and cozy. There is a temperature difference as well. The cold air cannot come inside the room and the hot air does not have a way out.

All the hot air is accumulated in the room. This creates a larger humidity inside the room. The moisture would try to go to the lower humidity area or in the cold area.

As the window remains cold, the moisture gets accumulated there. The windows provide direct contact with the outside.

The cold air present outside would make the window cold. The cold region would gather moisture. That’s why the window becomes wet during the winter. The moisture in the window is not a bad thing unless it results in growing the molds.

Molds grow whenever they find moisture. The accumulation of moisture in the window for a long time can be a good place for the mold to grow. Before further damage occurs, you should wipe the moisture from the window.

In the morning

The early morning is perfect for the dews to drop. The dew would be on the leaves, on the windows, on places.

Some might find it annoying while some love it. The weather seems to be covered with a new look. A new start to the day. The reason which causes this is given below.

Low temperature:

Generally, the temperature outside remains low during the morning and the night. The moisture moves from the warmer places to the cold places.

As a result, the warmer air from the room gets on the cold window. Which creates a wet window. Wiping it off would be okay before it creates marks.

Is it normal for windows to be wet on the inside?

It is normal for windows to be wet on the inside to some extent. The weather changes would definitely make the windows wet. You would not be able to protect the window from getting moisture on it. Well, there is also no reason for panic.

The reason for the window getting foggy is not because the window has been damaged. It is due to the fluctuation in the humidity and temperature between the inside and outside of the home.

As the weather changes, the humidity would change as well. Thus, the formation of moisture in the window is also common.

You can try to get rid of it after setting up a proper environment. Controlling the humidity inside the room can prevent the accumulation of moisture in the window. There are also other ways to keep the window dry.

How much condensation on windows is normal?

Excessive condensation on windows is indeed abnormal while the normal condensation would wipe away at once.

Especially during cold weather, wiping the moisture becomes tough as the condensation of the moisture occurs frequently. Some windows provide no condensation when the internal humidity is up to 37%.

But the cold weather can create a great humidity gradient between the room and the exterior.

It is tough to decide on an average point of condensation which would be easier to handle. Instead, the condensation during the winter is rather annoying and almost gets on my nerves.

Better to get rid of the moisture accumulation on the windows.

You can follow some methods to keep the room humidity in control while creating less condensation of moisture on the window. Try using them instead of being faded up with the wet window.

How do you stop condensation on inside of windows?

The condensation of the moisture inside the windows can be bad for the window as well.

Especially, when the moisture remains on the window for a long time. You should try to stop the moisture accumulation to keep the windows safe. Follow below to stop condensation inside of windows.

Keep the windows open:

Opening the windows would help the excess moisture go outside. Well, the moisture gathers on the window because they have no place to go.

They would move to the cold area. Making a way for the moisture would create less humidity inside the room. Thus, the condensation can be stopped temporarily.

Proper ventilation:

The proper ventilation of the air can help to stop the condensation of moisture. Especially in the places such as bathrooms, and the kitchen, proper ventilation should be there.

Or else make a way to let the air out. This would also contribute to controlling the humidity and temperature inside the house.

Turn off the humidifier:

The humidifier adds moisture to the place. Already the condensation of the moisture in the window is caused because of the excess moisture in the room. If the humidifier adds up more moisture, it would result in more condensation. Better to turn it off.

Wipe off the condensations:

Wiping off the condensations would also help. Well, cover the wet areas or any moisture. So that the air cannot take the moisture and increase its humidity. Wipe off the wet places. Do not let the air take moisture out of it and result in condensation.

How do you get rid of condensation in between double glazed windows?

The double glazed windows are the most suitable ones to prevent condensation. Yet, condensation can occur on the double glazed windows up to some extent. If you want to keep the double glazed window condensation free, you can follow the below.

Air ventilation:

Air ventilation is required to minimize the condensation on the window. You can keep your double glazed window a bit open.

Do not open it too much. Make enough route for the air to pass. This would help to let the air out of the room and get rid of the condensation in between the double glazed windows.

Wipe away the moisture:

You should wipe off the moisture before it sits up on the window. Well, some use moisture absorbers to clean the moisture from the window. It would help to clean the window completely. Try using the absorbers to clean in between the window.

Use a dehumidifier:

A dehumidifier would take the moisture away unlike the humidifier. You can use the dehumidifier to get rid of the moisture from the windows. It would take the moisture from the double glazed windows and make them clean.


Many try using hair drying to get rid of the condensation in between the double glazed windows.

You can try this but not when it has already been used to dry stuff. The hair dryers are used on the windows to absorb the moisture, not to leave moisture.

Final Thoughts

Overall, the windows get wet due to the fluctuation in the temperature and the humidity between the rooms and exterior. The excess moisture has to leave the room. They would rather get stuck in the window which acts as cold air for the moisture. Thus, moisture gathers in the window.
