Understanding Condensation in Double Glazed Windows

Condensation between window panes in double glazed windows, often referred to as “window condensation,” is a telltale sign that not all is well with your insulated glass units (IGUs).

This phenomenon occurs when the sealant holding the panes of an insulated window together fails, allowing moisture to seep into the once-sealed space. The primary function of these seals is to maintain a barrier against the elements, keeping the inert gas between the panes stable and ensuring optimal thermal performance in your double pane window.

The Signs of a Failed Window Seal

When the seal deteriorates, which can be due to factors such as age, wear and tear, or even improper installation, the inert gas escapes, and moist air from the outside environment takes its place. As temperatures fluctuate, this moisture condenses into water droplets, fog, or frost, which becomes visible between the glass panes of your insulated window.

Addressing window condensation in double glazing is essential, not only for maintaining clear visibility, which reduces the need for frequent window cleaning, but also for preserving the window’s insulating properties. Ignoring this issue can lead to increased energy bills and reduced comfort within your home, underscoring the importance of timely action.

Left unchecked, it can lead to more significant issues, including mould growth, wood rot around the window frames, and a noticeable decrease in the energy efficiency of your home. Understanding the cause of condensation is the first step towards a clear and lasting solution for glass panels.

DIY Solutions for Removing Condensation

Tackling condensation between your window panes doesn’t always require professional help. With a few tools and some elbow grease, you can address minor condensation issues yourself.

Necessary Tools and Materials

Before you begin, gather the necessary tools: a drill with a small, precise bit, a lint-free cloth, and a high-quality liquid sealant. Ensure you have a microfiber cloth on hand to gently wipe away any moisture that escapes during the process. For the sealant, choose a product specifically designed for windows to ensure a lasting fix.

The Drilling Method

The drilling method is a widely used DIY technique for removing condensation from a double pane window. Start by carefully drilling a small hole at the top and bottom of the window pane where the condensation is present.

This allows the trapped moist air to escape and provides an avenue for you to absorb moisture from the window cavity. Use the lint-free cloth to gently dab and absorb the condensation. Once the window space is dry, apply the liquid sealant to the drilled holes to reseal the space and prevent future condensation. Remember, this is a short-term solution and may not restore the full thermal performance of your double glazed windows.

While these DIY methods can provide a temporary fix to remove condensation from double glazing, they do not address the root cause of the problem—a failed seal. For a long-term solution, consider consulting with a professional to discuss the replacement of the insulated glass unit or the entire window to ensure energy efficiency and prevent future condensation.

Professional Solutions for Window Condensation

When DIY methods fall short, professional solutions for window condensation offer a more robust and lasting fix. Experts in window repair can provide defogging services, which involve drilling precise holes to remove moisture and then sealing them with a special solution to prevent future condensation.

For a more permanent resolution, professionals may recommend replacing the entire insulated glass unit (IGU). This not only eradicates the condensation issue but also restores the window’s thermal efficiency.

Trusting the job to seasoned professionals ensures that your double glazed windows regain their clarity and insulating properties, safeguarding your home against heat loss and excess energy consumption.

Long-Term Fixes for Condensation Problems

For homeowners facing persistent window condensation, long-term solutions are essential for maintaining both visibility and thermal efficiency. When temporary fixes no longer suffice, it’s time to consider more permanent measures to ensure your home’s comfort and energy performance with modern windows.

Choosing Replacement Windows

Selecting new windows is not just about addressing the immediate condensation issue; it’s about enhancing the overall thermal window performance. When choosing replacement windows, consider options that offer superior insulation and energy efficiency.

Look for features like double or triple glazing, low-emissivity coatings, and inert gas fills, which all contribute to an insulated window’s ability to minimize heat transfer. Replacing not the whole window but just the affected tempered glass unit can be a cost-effective solution if the frames and surrounding structures are still in good condition.

However, if multiple panes are compromised or if you’re looking to upgrade to a more energy-efficient system, replacing the entire window may be the best option. This not only resolves the window condensation issue but also enhances the overall energy efficiency of your home, potentially leading to significant savings on energy bills.

Preventing Future Condensation

Ensuring that your double pane windows remain clear and free of condensation is as much about proactive prevention as it is about addressing existing issues. Proper maintenance of your windows is key to preventing the recurrence of condensation.

Regularly check the seals of your double pane windows for signs of wear and tear, and make sure that the space around the window is well insulated. Additionally, managing the humidity levels within your home can play a significant role in preventing condensation in double glazing. Use dehumidifiers if necessary, and ensure that your living space is well-ventilated to allow moist air to escape.


In conclusion, while window condensation can be a nuisance, there are several effective strategies to eliminate it and prevent its return. From DIY fixes to professional repairs and replacement of double pane windows, you have options to restore clarity and functionality to your windows.

Remember, maintaining your insulated windows properly not only addresses condensation but also enhances the overall energy efficiency of your home. By taking the right steps today, you can enjoy clear views and a comfortable indoor environment for many years to come.
