Double-pane windows are a great way to insulate your home. However, they can be prone to condensation build-up, which can be frustrating and impact visibility. This is caused by warm, humid air coming into contact with the colder glass, which then condenses and becomes trapped between the two panes of glass. This can be removed by using a dehumidifier, moisture absorber, or hair dryer, but these are only temporary solutions. The best long-term solution is to fix the main problem, which is almost always a broken seal, by hiring a professional to reseal or replace the window.

What You'll Learn
Causes of moisture in double-paned windows
Double-pane windows are designed to provide better insulation by reducing heat transfer and preventing drafts. However, over time, they can develop moisture problems that affect their appearance and functionality. This happens due to several factors, which can be temporary or permanent.
Temperature Fluctuations
The constant pressure fluctuations caused by thermal pumping can stress the seal, causing small fractures that grow over time. This allows increasing amounts of infiltration and exfiltration of gas from the space between the panes. Windows on the sunny side of a home are more susceptible to this issue, as they experience larger temperature swings, resulting in greater amounts of thermal pumping and seal stress.
Weather Conditions
Extreme weather conditions can cause the gas inside the sealed unit to expand and contract, creating movement that stresses the seals and creates gaps. This allows moisture to infiltrate the space between the panes, leading to fogging and condensation.
Seal Failure
The seal protecting the window assembly can fail due to various factors, including temperature fluctuations, exposure to the elements, and general wear and tear. When the seal breaks, it no longer effectively blocks moisture from entering the space between the panes. This leads to condensation and a foggy appearance, reducing visibility and potentially damaging the window frame.
Production Defects
In some cases, double-pane windows may have been manufactured with defective seals that contain small defects. These defects can cause the window to fail prematurely, resulting in moisture intrusion and condensation between the panes.
It is important to address moisture issues in double-paned windows promptly to prevent long-term damage. While temporary solutions, such as using moisture absorbers or applying WD-40, can help clear condensation, consulting a professional glass repair company is advisable for persistent or severe issues.

Short-term fixes for moisture removal
If you notice moisture inside your double-paned windows, it's a sign that the seal between the panes has failed, allowing moisture to enter the space between the glass. While replacing the window or the glass unit is the best long-term solution, there are a few short-term fixes you can try to remove the moisture and improve the appearance of your windows.
Use a Dehumidifier
A dehumidifier is an electrical appliance that reduces and maintains the humidity levels in the air. Place a dehumidifier near the affected window, and it will help absorb the condensation between the panes. This is a reasonably priced option that doesn't require hiring a professional.
Moisture Absorbers
Moisture absorbers are another inexpensive household item that can be used to remove dampness from within your home. Place the moisture absorbers along the bottom edge of the window, and they will absorb the condensation. You may need to repeat this process a few times for full effectiveness.
Heat Application
Common household items such as space heaters or hair dryers can be used to clear condensation from double-pane windows. Simply place the heat source near the window and turn it on. The heat will help absorb the moisture between the panes. However, this method only provides a temporary solution.
Vinegar and Water Solution
Mix equal parts vinegar and water in a spray bottle. Spray this solution onto the interior side of the window, focusing on hazy areas. Gently wipe the glass with a microfiber or lint-free cloth using a circular motion. If necessary, follow up with a glass cleaner or an ammonia and water solution, and finally, wipe away any excess moisture with a dry cloth. This method is suitable for removing haze from the surface of the glass, but if the haze is between the panes, it may indicate a failed seal that requires professional attention.
While these short-term fixes can help with moisture removal, it's important to consider a more permanent solution to restore the insulating and energy-efficient properties of your double-paned windows.

Long-term solutions for moisture prevention
Double-pane windows are designed to have two seals: an inner seal to protect against moisture and corrosion, and an outer seal to protect the window's strength. Over time, the constant pressure fluctuations caused by thermal pumping will stress the seal, leading to small fractures that will grow in size. This allows increasing amounts of infiltration and exfiltration of argon from the space between the panes. As a result, once the seal is broken, moisture begins to form between the glass plates, causing a milky, foggy appearance.
Regular Maintenance and Inspections
Routine inspections and regular maintenance can help catch issues early and prevent future moisture problems. Check the sealant and weather stripping around your windows, as cracked and peeling weather stripping allows moisture in and causes condensation. Replacing any damaged sealant or weather stripping will help prevent issues.
Establish Proper Water Drainage
Ensure proper water drainage around your home to prevent water from pooling near window sills and frames. Poor drainage can result in water retention, which is a common cause of moisture buildup.
Avoid Direct Sunlight Exposure
Windows that receive direct sunlight will experience larger temperature swings, leading to greater thermal pumping, seal stress, and higher failure rates. Consider ways to minimise direct exposure to sunlight, such as using curtains or blinds during the hottest parts of the day.
Professional Repair or Replacement
While there are temporary fixes like using a dehumidifier or hair dryer to absorb moisture, addressing the underlying seal failure is crucial. Professional window installers have the expertise and tools to correctly diagnose the problem and implement the best solution. They can also ensure proper sealing of new units to prevent future moisture issues.
Window "Defogging"
A newer method, known as "defogging," involves drilling a small hole into the window and inserting a defogger device. This process removes condensation by releasing moisture during thermal pumping. However, opinions vary on its effectiveness as a long-term solution, as it may only address the symptom of seal failure without fixing the seal itself.

Maintenance and prevention
Double-pane windows are a great way to insulate your home from outside elements. They are typically made up of two glass panes separated by a spacer, usually metal or plastic, and filled with a gas like argon or krypton. The double panes prevent heat from escaping in the winter and keep your home cooler in the summer.
However, double-pane windows can be prone to condensation build-up, especially in winter, due to the temperature difference between the outside and inside air. This condensation can get trapped between the panes, giving your windows a milky, foggy look and reducing their energy efficiency.
To prevent and address this issue, here are some maintenance tips:
- Annual inspections: Inspect your windows annually for any signs of wear or damage, especially checking the seals and frame integrity. Early detection of any issues can prevent them from escalating.
- Ventilation and humidity control: Use exhaust fans in high-humidity areas like bathrooms and kitchens to minimise moisture build-up. Maintain indoor humidity levels between 30% and 50% to reduce condensation. Air conditioners and dehumidifiers can help manage these levels.
- Address drainage issues: Ensure proper drainage around your windows. Water retention in the frame or improper drainage can lead to seal breakage.
- Limit direct sunlight exposure: Direct sunlight exposure can cause the glass to expand, contract, and weaken over time, leading to seal breakage.
- Maintain sealant and weather stripping: Check the sealant and weather stripping around your windows regularly. Cracked or peeling weather stripping allows moisture to enter and cause condensation. Replacing damaged sealant or weather stripping will help prevent future issues.
- Consider resealing: If your windows continue to have condensation issues, consider hiring a professional to carry out a resealing process to prevent future problems.
While some temporary solutions can help remove condensation, such as using a hairdryer or vinegar solution, addressing the root cause through proper maintenance and prevention is key to maintaining clear and functional double-pane windows.
