Demystifying Moisture Between Panes and Finding Solutions

Stop Window Condensation & Keep Your View Clear

Stepping into your home and being greeted by a fogged-up window can be frustrating, interrupting your view and potentially indicating a larger issue. While condensation on the interior of windows is a common occurrence, finding moisture between the panes of a double-glazed window signifies a compromised seal. This blog post dives into the causes of moisture between window panes, explores effective solutions on how to remove moisture from between window panes, and offers preventative measures to stop condensation on windows and keep your windows clear and efficient.

Understanding the Problem: How Does Moisture Get Between Panes?

Modern windows are typically double-glazed, meaning they consist of two panes separated by a spacer filled with dry air or inert gas. This design creates an insulating barrier, enhancing energy efficiency. However, over time, the seal between the panes can deteriorate due to various factors:

Natural wear and tear: Seals can weaken due to prolonged exposure to weather extremes like heat and cold, causing them to crack or lose their elasticity.

Improper installation: Faulty installation during window replacement can compromise the seal’s integrity from the outset.

Manufacturing defects: While rare, manufacturing flaws can create weak spots in the seal, allowing moisture to enter.

Moisture’s Detrimental Effects and Why You Should Address It:

The presence of moisture between window panes is not merely an aesthetic concern. It can lead to several negative consequences:

Reduced energy efficiency: The insulating properties of the window diminish, potentially leading to higher energy bills for heating and cooling.

Mould and mildew growth: Moisture provides a breeding ground for mould and mildew, which can pose health risks and damage surrounding materials.

Foggy windows: Condensation trapped between the panes obstructs your view and reduces natural light entering your home.

Window degradation: Over time, moisture can damage the window frame and surrounding materials, leading to costly repairs or replacements.

Solutions for Removing Moisture Between Window Panes:

Unfortunately, there’s no simple DIY fix on how to remove moisture from between window panes. However, depending on the severity of the issue and your window type, two primary solutions might be suitable:

Desiccant Replacement

This option involves injecting a new desiccant material into the spacer bar through strategically drilled holes in the pane. The desiccant absorbs the existing moisture, restoring the insulating properties of the window. It’s crucial to note that this procedure requires expertise and specialised equipment. Consider seeking professional assistance from a qualified window repair company to ensure proper execution and avoid further damage to your windows.

Window Replacement

If the seal is severely compromised or the window frame is damaged, replacing the entire window unit might be the most effective solution. This option guarantees the complete removal of moisture and offers the benefits of improved energy efficiency and a fresh aesthetic. When replacing windows, consider investing in high-quality units with durable seals and warranties to ensure long-term performance.

Preventative Measures on How Do You Stop Condensation on Windows

While moisture between window panes can occur due to unforeseen factors, some proactive measures can help minimise the risk and how do you stop condensation on windows:

Enhance Ventilation

Increase airflow: Open windows for short periods throughout the day, especially during and after activities that generate moisture, like showering, cooking, and laundry. This allows humid air to escape and be replaced by drier air from outside.

Utilise exhaust fans: Ensure bathroom and kitchen exhaust fans are functioning properly and run them during and for a short period after using these spaces. This helps remove moisture directly from the source.

Invest in ventilation systems: Consider installing whole-house ventilation systems like balanced ventilation or heat recovery ventilators (HRVs). These systems continuously remove stale, moist air and replace it with fresh, dry air, helping to control moisture levels throughout your home.

Maintain Consistent Temperature

Regulate indoor temperature: Aim for a consistent and moderate indoor temperature, ideally around 68°F (20°C). This reduces the temperature difference between the warm interior air and the cooler window surface, where condensation forms.

Control the heat source: Avoid placing furniture or heavy drapes directly in front of radiators or heat sources, as this can trap warm air and contribute to condensation on nearby windows.

Utilise dehumidifiers: If you live in a humid climate or struggle to maintain consistent temperature, consider using a dehumidifier to help remove excess moisture from the air.

Promote Window Cleanliness and Inspection

Regular cleaning: Regularly clean your windows, both inside and outside, to remove dirt and dust that can attract condensation. Use a clean, lint-free cloth and a mild cleaning solution.

Double-pane inspection: Regularly inspect your windows for any signs of seal failure, such as fogging between the panes, drafts, or visible cracks. If you suspect a broken seal, contact a professional how do you stop condensation on windows window repair company to address the issue promptly, as this can lead to moisture getting trapped between the panes.

Bonus Tip

Insulating window coverings: Consider using insulating window treatments like cellular shades or thermal curtains during colder months. These create an additional layer of insulation between the window and the room, reducing heat loss and minimising the temperature difference that can lead to condensation.

By implementing these preventative measures, you can create a more balanced and controlled environment within your home, effectively stopping condensation on windows and preventing the potential problems associated with moisture buildup. Remember, consistent effort and awareness will go a long way in maintaining clear windows and ensuring a comfortable, healthy living space.


Moisture between window panes, while frustrating, can be addressed effectively through professional intervention with moisture removal or window replacement. By understanding the causes and consequences of this issue, and by implementing preventative measures to stop condensation on windows, you can maintain clear, efficient windows and enjoy the full benefits of natural light and optimal home comfort. Remember, investing in your windows is an investment in your home’s energy efficiency, value, and overall well-being.
