As winter descends upon Burien, residents anticipate cooler temperatures, rain-laden days and the all-too-familiar challenge of window condensation. Dealing with foggy windows not only obstructs your view but can also lead to potential issues like mold and mildew in the home. 

Before going into practical tips on how to combat winter window condensation in Burien, WA, we will go through the causes and the reasons why condensation occurs, especially during this period of the year. Knowing the particular cause can help you determine the best course of action in mitigating window moisture-related issues, through both short-term and long-term projects and investments for your home. 

Understanding the Causes of Window Condensation

Before discussing practical solutions, it's essential to grasp the factors contributing to window condensation. Identifying the root causes helps in implementing targeted and effective solutions to address this common issue.

Winter window condensation is a common occurrence in many homes in many locations, including Burien, WA. Most often, the main cause is the difference in temperature between the warm indoor air and the cold outdoor air. Some of the main reasons for winter window condensation can be: 

  • Temperature difference: During the colder months, the interior temperature of your home is maintained to keep you warm and comfortable. At the same time, the windows have much lower temperature than the indoor temperature because they are in direct contact with the cold outdoor air. This temperature difference causes the moisture in the air to condense on the window glass. 
  • High humidity indoors: Indoor activities such as showering, cooking and even breathing release moisture into the indoor air. At the same time, the outdoor air is less capable of holding moisture during the colder months, leading to higher relative humidity levels indoors. When the warm and humid indoor air comes in contact with a window surface that is cold, it reaches a dew point and condensates. 
  • Inadequate ventilation: Elevated humidity levels in the home can be caused by poor ventilation. Without proper airflow, the moisture generated indoors has no means to escape, leading to more than regular condensation on the windows. 
  • Limited circulation of the air: Furniture and window coverings that are positioned too close to or in front of the windows can obstruct air circulation, which allows the cold surface to persist due to the limited air movement. This can be another cause of abnormal window condensation. 

Determining the proper cause for the window condensation in your home during winter can help you devise the proper plan for combating condensation. 

1. Improve Ventilation for Optimal Airflow

Proper ventilation plays a pivotal role in reducing window condensation. Ensure your home has sufficient airflow by installing exhaust fans, periodically opening windows and considering the use of ventilation systems. This approach helps balance indoor humidity levels, preventing excessive moisture buildup on your windows.

2. Upgrade to Energy-Efficient Windows

Consider investing in energy-efficient windows to combat condensation effectively. Modern windows with advanced glazing technologies aid in regulating indoor temperatures, reducing the likelihood of condensation. High-quality, energy-efficient windows are not only helping with condensation — they also provide insulation for your home, lowering your heating and cooling bills. 

3. Leverage Dehumidifiers for Moisture Control

Dehumidifiers are valuable tools for maintaining optimal humidity levels within your home. Placing dehumidifiers strategically in areas prone to excess moisture, such as kitchens and bathrooms, can significantly reduce condensation on windows in those areas. This approach proves particularly effective in homes where traditional ventilation methods may be insufficient. 

4. Consider Thermal Curtains for Added Insulation

Thermal curtains provide an additional layer of insulation, reducing heat transfer and helping to maintain a more stable temperature near the windows. By acting as a buffer, these curtains prevent warm air from reaching the cold window surface and causing condensation. 

This affordable and aesthetically pleasing solution can be particularly effective in homes with large or drafty windows.

5. Implement Regular Maintenance and Inspection Practices

Simple maintenance practices can go a long way in preventing window condensation. Regularly wiping down your windows to remove existing moisture and prevent the growth of mold or mildew is essential. Additionally, keeping window sills dry and clear of debris ensures proper drainage, reducing the likelihood of moisture-related issues.

Apart from regular maintenance, make sure to conduct a thorough inspection of your windows for any gaps, cracks or leaks that might contribute to condensation. Addressing these issues with proper sealing or weather stripping can create a tighter barrier against the cold, minimizing the chance of moisture accumulating on your windows.

It is essential to perform these maintenance and inspection tactics throughout the entire year and be prepared when the colder months arrive.
