How to Repair Double Glazed Windows

Many properties with double-glazing experience issues with condensation, a lower insulation quality and windows that are difficult to open. These issues are usually a result of a problem with the hinges, mechanisms or handles.

You can repair these windows by following a few simple steps.

Cracked Panes

If a double-pane windows is damaged, it's an urgent problem that needs to be addressed immediately. If a double- or triple-pane window cracks, the gas that insulates it to keep out cold air and warm air during winter escapes. This means that your home is less well-insulated. Cracks also worsen over time, so repairing them now can prevent a bigger problem in the future.

The most important thing to do when a crack appears is to determine the cause of it. The most commonly cited reason is a structural issue which can cause the breakage, but it's also possible that there was an impact of a different kind. In this case it's crucial to examine the rest of your windows for damage and to determine the next steps to take.

It's also an excellent idea to look over the area around your home for any other problems which could be contributing to the crack. For instance windows that are located near to walls or doors, the stress of expansion and contraction caused by temperature changes may cause cracking.

Depending on the reason for the crack, there are a variety of ways to repair the issue. If the crack was caused by an impact, you may be able replace just the damaged glass. It is possible to replace the entire window frame. This is a more complicated solution and requires the assistance of an expert.

If you're dealing with a crack that didn't cause the frame move, it's normally simple to put an adhesive between the broken panes. This will close the crack and prevent further damage to your window.

Covering the crack with clear tape is another option. This isn't the best appearance, but it can stop bugs and drafts from getting into your home. An alternative is a glass repair film that's made to be easily applied and offers more durable protection. Many double glazing companies provide this service, which is worth the investment to protect your windows.

Condensation Build-Up

Condensation that builds up between the panes of double-glazing is among the most common reasons why homeowners need to repair their windows. It is typically a sign that the seal between two window panes failed, allowing water to be able to. This water vapour can cause condensation and other issues that could need the window replaced.

Double glazing reduces condensation better than single panes of glass because it has a space between the two panes which is filled with air or non-toxic gases. The space between the glass and window frame is separated by a spacer which acts as an insulation. This helps prevent loss of heat. In a lot of cases, the spacer bar is stuffed with a silica gel which is very effective at taking in moisture and preventing it from leaking between the panes of glass.

This is why it's important to wipe down your windows on a regular basis and keep them clean, as this will minimise the amount of condensation that accumulates and allow it to evaporate. Opening windows and using extraction fans can help to remove moisture.

Installing a dehumidifier can be another method to fight condensation. These units can be purchased for between PS60-PS150. They are a wise investment that will not only reduce condensation, but also stop the growth of mould within your home, too.

Condensation between the glass panes of your double glazing could occur because the outside air is colder than the inner window pane, causing the surface to cool down and cause condensation. It can also happen when you change the temperature in your home, such as by turning off or on the heating.

Condensation could also be an indication of poor double glazing, because older models were constructed with rubber strips, rather than the latest silicone type. They can become damaged with time. It is possible to repair your seals, however this is only a temporary solution since the window will eventually fail in a different location.

Stained Glass

If you have a problem with a double glazed window handle or lock, it is possible to repair it rather than having to replace the entire glass pane. This is not a simple DIY task, as you will need special tools to ensure that the repair is done right.

Most homeowners with double glazing complain that their windows or doors are difficult to open. This is typically caused by a slight warping of the frame or hinges but can also be due to problems with the sealing. In some cases the issue could be more severe than this and it is worth speaking to a professional regarding the possibilities available.

Another frequent complaint is the formation of condensation between glass panes. This could be a sign of a leaky seal that isn't holding the gases that are insulating between the glass panes. It is also an easy fix and the gas that insulates can be restored with a special adhesive to seal the gap between the panes.



Start by placing the faulty window on a flat surface. Peel back the black sealant to expose the silver spacer bar and cut into it with a sharp blade, being sure to stay under the base of the glass and the silver spacer bar. After you have separated the two pieces, put the top glass pane on your work surface. It is recommended to wear gloves during this step. Clean the glazed side that faces the frame and the spacer frame. Make sure to get rid of any marks or smears because they can affect the seal of the window when it is put back together. The last step is to place the new spacer on the glass pane. Spread the adhesive along the edge to help it stick to the glass and silver frame. Allow to set before re-assembling. It is best to have two people help you as it can be difficult to align everything.

Gasket Seals

While double glazing is highly durable and designed to last for years to come, there are still issues that can arise occasionally. From draughts, to problems in closing or opening, it is important to fix any issues promptly to prevent them from becoming worse.

One of the most common problems faced by double-glazed owners is the formation of condensation between the two panes of glass. This is due to the failure of the desiccant which absorbs moisture in the air inside the gaps that are insulated. If the desiccant is not working it can cause condensation to form within minutes and leave a dark mark on the window.

Another issue that could arise is when the gasket seal fails to keep water and other pollutants out of the gap. This could lead to leaks around the edges of the frame, and could also cause damage to the surface of the double glazed unit itself. Contact your installer right away if you observe any signs that your double-glazed units leak.

Many companies offer a warranty on their products and these often come with a guarantee period of either 10 or 20 years, with some even offering lifetime assurances. Check the details of your warranty to see what's covered and how long it will last.

RepairMyWindowsAndDoors  may want to try and solve any hardware issues yourself before contacting a double glazing supplier. For example, you can try cooling the mechanism or oiling it to see if this fixes the issue. You can also try taking the handle off or the window handle and cleaning it prior to putting it back in place.

It is also essential to determine if your local council offers insulation grants to aid in the replacement or repair of your double-glazed windows. There are a variety of methods to apply and certain areas will require a particular form of application or proof of eligibility, so it is always worth checking with your local authority prior to deciding on how to proceed.
