How to Repair Double Glazing Windows

You might experience issues with the handles of your double glazing gaskets, hinges and handles. They can usually be fixed without needing to replace your windows completely, saving you time and money.

One common issue is condensation that has accumulated in the space between the two panes of glass. This is a sign that the window requires to be repaired.

1. Broken Panes

A damaged double pane window is a major issue and can expose your home to the elements. However, it's not always necessary to replace the entire window sash to address this issue. In fact, double pane windows are typically able to be repaired with the use of a specific adhesive that is put inside the cracks to prevent them from getting worse.

This short-term method is employed to avoid superficial fractures (such stress cracks) which can develop when temperature fluctuations cause the glass to shrink and expand. If your glass has been damaged, you may need to remove and replace the entire window.

Sometimes, the seals between two glass panes may get damaged or worn-out, causing condensation and misting on the windows. Typically, these problems result from moisture that is trapped between the two glass panes or dripping through the window frame and into the wall. Whatever the cause, moisture is bad news for windows with double glazing as it can cause water damage and mold growth that can be costly to treat.

You can try to control the problem by wiping down the windows of your double-glazed windows with cold, lukewarm water. This will temporarily resolve the issue, especially when it is warm and humid outside. You could also try a dehumidifier in the room where your double glazed windows are situated which is particularly useful during the summer.

If the issue continues, the double glazing expert will visit your home and clean the space between the panes of your glass. A tool can also be used to create an outline around the outside of the windows, allowing you to cut the glass with a glass cutter. After this is completed, you should take off all the glazing points and putty from the frame of your window opening. This is best done while the sash is still in place, although it's easier to work on a flat surface like a table.

2. Seals

The window seal is an integral component in double glazing and plays a crucial part in keeping your home energy efficient as well as draught-free and safe. The seal covers the entire part of the uPVC frame and provides an air-tight seal over the gas-filled space between the two panes of glass that make up the window. The seals are a vital element of double glazing's insulation. If they fail or experience problems it will decrease the effectiveness.

If your seals aren't doing their job, the result is condensation between the panes. This isn't just a nuisance; it can lead to mould and damp in your home. It can cause damage to floors, furniture, walls and cause serious health issues for people suffering from respiratory issues such as asthma.

The good news is that most double glazing companies will provide a service to repair windows without replacing the entire unit. This is not only less expensive but also faster and more sustainable. In the meantime, there are DIY options such as caulking to prevent moisture and leaks or lengths of self-adhesive seals that can be affixed directly to the junction between the window sash and frame.

In most instances, the easiest and most effective method to fix a damaged window seal is to call in a professional. They can replace the window seal and stop air and moisture from entering your home, which could cause expensive damage.

Make sure you know the warranty duration of your double glazing. It's usually between 10 to 20 years. This could save you money in the event that the seals have failed and the windows have to be replaced. Some installers may even drill holes into misted double glazing and then draw out the moisture to form an entirely new seal, and stop it from misting again in the future. This is a temporary fix and a plug must be put in to seal the hole.

3. Locking Mechanisms

Double-glazed windows have air gaps between the glass panes to provide insulation against changing temperatures outside and also to keep warm inside the house. This kind of window can also be described as an Insulated Unit (IGU). They can give you a lot of energy efficiency that can save on your heating costs. But, they're not indestructible and some problems may occur that require double-glazing repairs.

The majority of these issues are fixable and are less expensive than having to replace the entire window. It is best to contact a specialist company who offer repair services for double glazing, so that you can be sure that the repair is done correctly and with minimal hassle. Most of these companies will offer no-cost quotes so that you can compare prices and the quality of their work.


Examine the warranty included with the double-glazed window. This will usually cover the costs of repairing. This is a common feature of double-glazing installations and usually lasts from 10 to 20 years, however some companies offer lifetime guarantees.

double glazing repair may have blown out if you are unable to open the double-glazed windows, or if you notice there appears to be a cloud of mist between the panes. This could happen when the frame of the window shifts slightly, or if the packaging that keeps the glass sheets in place deteriorates with time.

There are ways that you can fix double-glazed windows yourself, but it is normally far easier to use a professional company. If you try to do it yourself, you must follow the manufacturer's guidelines and make use of the appropriate tools to complete the task. It is also worth bearing in the mind that if you attempt to remove the glass by yourself, you'll lose any guarantee you might have and could end up paying a higher bill than if you had simply contacted the company from whom you purchased your windows.

4. Weatherproofing

If your double glazing windows are difficult to open or have sagged, there are ways of fixing them. For instance, you could try oiling the mechanisms, hinges or handles to see if it aids. You can also replace gaskets to boost the performance of your windows and stop them from opening up to cold air and draughts. You can purchase them at a hardware store, or online, and they are easy to install. If you aren't able to tackle this task yourself, you can always have a professional do it for you.

Condensation between windows is another issue that is easily fixed. This is due to the window seal being damaged, which allows moisture to enter between the glass panes. This can cause mist to develop on the glass, which is both unattractive and ineffective.

One way of addressing this is to replace the gaskets which can be accomplished at home by anyone with little DIY experience. Gasket sealer is crucial for a good seal, and can help cut down on energy costs. You can also apply the calk to fill in any cracks. This will give your windows an extra boost of weatherproofing.

The seals can also fail on double-glazed windows. This can happen due to paint being used near the windows, home renovations or general wear and tear. It is crucial to repair your double-glazed windows as soon as they become misted.

However, there are times when it is best to replace your double glazed windows rather than repair them. This can include broken panes, extensive decay and frames that are no longer suitable for the double glazing units.
