Condensation on windows is a common issue in all kinds of homes, no matter if you live in a house or an apartment. It’s especially a problem in winter when warm indoor air hits the cold window glass, creating moisture and water droplets.

To reduce condensation on windows in winter, ensure proper ventilation by using exhaust fans, opening windows periodically, or using a dehumidifier. Additionally, you can add weather stripping to windows, use insulated curtains, or consider installing a heat recovery ventilation system.

It’s crucial to tackle condensation because too much moisture can lead to:

– Damage to walls and ceilings

– Mold growth and dampness

– Low air quality, leading to higher risk of respiratory problems.

To help you prepare before the winter arrives, we’ll show you how to stop condensation on windows in winter.

Causes of Condensation on Windows

Condensation on windows is caused by several factors:

Temperature Difference

Temperature difference between indoor and outdoor air. Condensation occurs when one side of a surface is much warmer or colder than the other.

High Humidity Levels

High humidity levels inside the home. Condensation usually forms on the warmer, more humid side. For instance, if the sun hits a cold window in the morning, condensation might form on the inside of the glass.

Poor Ventilation

Poor ventilation. How to prevent condensation on windows – you need to lower the indoor humidity. When there’s no airflow, moisture gets trapped inside your home. Ventilation needs to be improved to allow moisture to escape.

Effects of Condensation on Windows

Why do we need to stop condensation occurring on our windows? These are the harmful effects of condensation on windows:

Mold growth and mildew. Dampness or humidity favors microbial growth. Condensation on glass windows raises the humidity level indoors, creating the perfect environment for the development of mold and mildew.
Damage to window frames and sills. The accumulation of moisture over time will eventually corrode the structure of window frames and sills, leading to breakage.
Reduced visibility through windows. When your windows are covered in condensation, you won’t be able to spot any danger that could be lurking outside your home.

Now that you know how condensation on windows can be detrimental, let’s discuss how to stop condensation on windows in winter.

How to Prevent Condensation on Windows

There are several ways of how to prevent condensation on windows, such as:

Use Dehumidifier

Using a dehumidifier to lower indoor humidity levels. As explained, a difference in humidity level indoor and outdoor is the main culprit.

Increase Ventilation

Increase ventilation through opening windows or using exhaust fans. Allow moisture from bathrooms and the kitchen to exit your home so that it doesn’t accumulate inside and cause condensation on windows.

Use Weather Stripping or Caulk

Use weather-stripping or caulk to seal any leaks around windows. The first downside of leaking windows is condensation on the glass and even water pooling. So take the necessary action to solve this problem before it gets worse.

Install Storm Windows

How to stop condensation on windows in winter – Consider installing storm windows or double-pane windows. Storm windows are usually made of plastic or other materials that don’t get affected by moisture. As a result, warm air is contained and cold air is kept out. Double pane windows are helpful too because they trap heat between the two glass panes, making it harder for warm air to escape. They also prevent cold air from entering your home when a window is open in winter, without letting in extra moisture.

Tips for Managing Condensation on Windows

We’ve talked about how to prevent condensation on windows. But what can we do if those solutions aren’t applicable or are impractical for us? Here are the alternatives:

Use a squeegee or towel to wipe away excess moisture. These tools are inexpensive and are commonly sold in stores.
Place moisture-absorbing products, such as silica gel packets, near windows. Silica gel absorbs moisture and is commonly used as dessicant for dry food products to maintain crispiness. However, to avoid accidental ingestion, it’s not advisable to use this method if you have small children or free-roaming pets at home.
Keep blinds or curtains open during the day to allow air flow. Air exchange is vital in preventing the accumulation of moisture indoors.
