How to Repair Double Glazed Windows

Many homes with double-glazed windows have issues like condensation, a decline in insulation quality and windows that are difficult to open. These problems are typically a result of a problem with the hinges, mechanisms or handles.

Repairing these windows is possible by following a few simple steps.

Cracked Panes

A double-paned windows that are cracked is a serious issue that needs to be dealt with immediately. Double- and triple-pane windows are insulated by gases that keep warm air in the winter and cold air out. So, when one of these panes cracks the gas escapes and your home is less well-insulated. Cracks can also get worse over time, so repairing them early can prevent a larger issue in the future.

The most important step to take when you notice a crack is to determine what caused it. The most commonly cited cause is a structural issue that could cause crack, but it's also possible that there was an impact of some sort. In this instance, it's important to check the rest of your windows for damage and determine the best course of action to take to fix the issue.

It is also an excellent idea to look over the surrounding area of your home for any other problems that could be causing the crack. For instance the windows are situated near walls and doors, the stress of contraction and expansion caused by temperature changes may be causing the cracking.

Depending on the cause of the crack, there are various solutions to fix it. If the crack was caused by a blow, you may be able to replace only the broken glass. It could be necessary to replace the entire window frame. This is a more complicated solution and requires the help of an expert.

If you have a crack in the glass that didn't cause the frame to move then it is usually easy to apply adhesive between the damaged panes. This will repair the crack and stop further damage to your window.

Another option that's simple is to cover the crack with clear tape. It's not the most appealing appearance, but it can keep bugs and drafts from getting into your home. An alternative is the glass repair film which is designed to be quickly applied and offers more durable protection. Many double glazing companies offer this product, which is worth the cost to protect your windows.

Condensation Build-Up

Condensation build-up between the panes of double-glazing is one of the most common reasons why homeowners need to repair their windows. It's typically a sign that the seal between two windows was not strong enough, allowing water to get in. This moisture can cause condensation and other problems that may require the replacement of the window.

Double glazing is more effective in decreasing condensation than single pane windows because it features an air space between the glass that is either filled with air or gas that is non-toxic. The space between the glass and the window frame is separated by a spacer which acts as insulator. upvc repair helps to prevent loss of heat. In many instances the spacer bar has silica gel, which is efficient in preventing moisture from getting between the glass panes.

It is therefore essential to clean and regularly clean your windows. This will decrease the amount of moisture that accumulates and let it evaporate. Using extractor fans or opening the windows to create more air flow can also help remove excess moisture.

Another method to fight condensation is by installing a dehumidifier in your home. They can be purchased for between PS60-PS150. They are a good investment that will not just reduce condensation but prevent mould growth in your home as well.

Condensation can occur between the glass panes of your double glazing due to the outer air may be colder than the interior window pane. This causes the glass's surface to cool and create condensation. It could also occur when you alter the temperature in your home, such as by switching off or turning on the heating.

In reality, condensation may be an indication of poor double glazing construction since some older models are constructed with rubber strips instead of the more modern silicone type that can degrade over time. In certain cases, it may be possible to have your seals replaced but it's worth noting that this will only be a short term solution as the window will eventually fail in a different area, which means you'll need to replace it in the future.

Stained Glass

It is possible to repair a double-glazed window handle locking mechanism, rather than replacing the entire pane of glass. However, this isn't always a do-it-yourself project as specific tools are required to ensure the repair is done correctly and does not compromise the seal or the function of the window.

The most frequent complaint from homeowners of double glazing is that their doors or windows are becoming difficult to open and close. This could be due to a slight warping in the frame or hinges however it could also be a problem with the seal. In certain cases, the issue could be more serious and it is advisable to talk with a professional about the possibilities available.

Condensation between the glass panes is a different complaint. This could indicate that the seal is failing and is not able to hold the insulating gas between the panes. This is a simple fix. The gas that is insulating can be restored by using a special glue to seal the gap.

Begin by placing the damaged window on a flat surface. Peel back the black sealant gently to reveal the silver spacer bars. Cut them into pieces using a sharp knife, staying just below the bottom of both the glass and the spacer bars. Once you have separated the two pieces, place the top glass pane on the work surface. It is best to use gloves for this step. Clean the glazed side that faces the frame as well as the spacer frame. Make sure to get rid of any marks and smears, since these can affect the seal of the window when it is reassembled. The last step is to place the new spacer on the glass pane. Spread the adhesive along the edge to allow it to adhere to the glass and silver spacer frame. Allow it to set before reassembling. It is best to have two people assist you since it may be difficult to align everything.

Gasket Seals

While double glazing is highly durable and designed to last for a long time to come, there are still problems that may arise from time to time. From draughts to issues in closing or opening it is essential to have any faults fixed quickly to prevent them from getting worse.

Condensation between the two panes is one of the most common problems that owners of double-glazed windows report. This is typically caused by an issue with the desiccant which absorbs moisture from the air within the insulated gap. When the desiccant is damaged it can cause condensation to form in minutes and form dark lines across the windows.

Another problem can occur when the gasket seal is not able to stop water and other pollutants from leaking into the insulated gap. This can cause leaks at the edges of the frame, and also damage the frame's surface. Contact your installer immediately if you spot any signs that your double-glazed units are leaking.

Many companies provide a warranty for their products and these often come with a guarantee period of 10 or 20 years, some even offering lifetime assurances. Examine the specifics of your warranty to find out what's covered and the length of time it will last.


You may want to try and solve any hardware issues yourself before contacting a double glazing supplier. For instance, you can try cooling the mechanism or lubricating it to see if this fixes the problem. You can also try taking the handle off or the window handle and then cleaning it before placing it back in place.

It is also essential to determine if your local council has any insulation grants to help pay for the replacement or repair of your double-glazed windows. There are many ways to apply, and some areas might require the proof of eligibility or a specific form of application. It is worth checking with the local authority to determine what they need to know.
