The Repair Double Glazing Case Study You'll Never Forget
How to Repair Double Glazed Windows

Many homes with double glazing are plagued by problems like condensation, a drop in the quality of insulation and windows that are difficult to open. These issues are usually caused by problems with the hinges or handles.

It is possible to repair these windows by following a couple of simple steps.

Cracked Panes

If a double-pane window is damaged, it's an urgent issue that needs to be addressed immediately. When a double or triple-pane window cracks the gas that seals it is unable to block cold air and warm air in winter is released. This means that your home is less well-insulated. Cracks can also get worse over time, so fixing them now prevents a potentially more serious issue in the future.

If a crack develops the most important thing is to identify what caused it. The most common cause is a structural issue which can cause the breakage, but it's also possible that it was caused by an impact of a different kind. In this situation it's imperative to inspect the rest of your windows for damage and determine the next steps to take.

It is also a good idea to inspect the area around your home for any other problems that could be contributing to the crack. For instance, if your windows are close to walls and doors and walls, the strain of expansion and contraction caused by temperature changes may cause cracking.

There are many ways to fix a crack depending on the source. For example, if it was caused by an impact, you might be able to work by replacing only the broken pane of glass. It is possible to replace the entire window frame. This is a more involved solution, and it requires the assistance of an expert.


If you've noticed cracks in the glass that did not cause the frame to move then it is usually easy to apply adhesive between the damaged panes. This can repair the crack and preserves your window from future problems It's certainly worth a try in this situation.

Another option that is fairly easy is to cover the crack with clear tape. This doesn't offer the best appearance, but it does keep 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. This is available from numerous double glazing companies and is well worth the investment to secure your windows.

Condensation Build-Up

Condensation that builds up between the two panes of double glazing is one of the most common reasons why people need to repair their windows. This is because it usually indicates that the seal between the window panes has been breached, allowing water vapour to get in. This moisture can then create condensation and other issues that may need the window replaced.

Double glazing is superior in reducing condensation than single pane windows since it has an air space between the glass that can be filled with air or gas that is non-toxic. The space is separated from the window frame by a spacer bar, which acts as an insulator and helps prevent heat loss. In a lot of cases, the spacer bar is filled with a silica gel, which is extremely effective at picking up moisture and preventing it from leaking between the glass panes.

This is why it's important to clean your windows on a regular basis and keep them clean as this will minimise the amount of condensation that forms and allows it to evaporate. Using extractor fans or opening the windows to allow for more air flow can also aid in removing excess moisture.

Installing a dehumidifier can be another way to combat condensation. These units can be picked up for around PS60-PS150 and are a wise investment that will not only decrease condensation, but also stop the growth of mould within your home, too.

Condensation between the glass panes of your double glazing can occur due to the fact that the outside air is colder than that of the inner window pane, causing the surface to cool and form condensation. It could also happen when you experience an increase in temperature, like turning on the heating or cooling of your home.

In reality, condensation may be an indication of a poor double glazing design as some of the older models are constructed with rubber strips instead of the more modern silicone variety which may degrade over time. It is possible to repair your seals, but this is only a temporary fix, as the window will eventually fail in another area.

Stained Glass

It is possible to repair a double-glazed window handle locking mechanism instead of replacing the entire pane of glass. But, this isn't necessarily a DIY job since specific tools are required to ensure that the repair is done correctly and doesn't compromise the seal or the function of the window.

The majority of homeowners who have double glazing complain that their doors or windows are difficult to open. This is typically caused by small warping in the frame or hinges, but it could also be due to problems with the sealing. In some cases the issue may be more serious and it is advisable to talk to a professional regarding the options available.

Condensation between the glass panes is another common complaint. This could indicate that the seal is failing and not able to hold the gas that insulates between the panes. Again, this is an easy fix and the gas that insulates can be restored with a special adhesive to seal the gap between the panes.

Place the damaged window on a flat surface. Peel back the black sealant to expose the silver spacer bar and cut it with a sharp blade making sure to stay below the glass's bottom and the silver spacer bar. Once you have separated the two pieces, put the top glass pane on the work surface. It is recommended to use gloves for this step. Clean the glazed surface that faces the frame and the spacer frame. Be sure to remove any marks and smears, as they could impact the sealing of the window when it is rebuilt. And lastly, place the new spacer onto the glass pane. Spread some adhesive around the edge to allow it to stick to the glass and silver frame. Let it set before reassembling. It is best to have two people do this job because it is difficult to set everything in the right place.

Gasket Seals

Double glazing is designed to last many years however, there are some issues that can occur. From draughts to problems with closing or opening it is essential to address any problems quickly to avoid them becoming worse.

Condensation between the two panes is one the most common issues double-glazed owners have to deal with. This is caused by the failure of the desiccant, which absorbs moisture in the air within the gaps that are insulated. Once upvc repair has failed, condensation can develop in minutes and cause dark lines across the windows.

Another issue could arise if the gasket seal is not able to keep water and other contaminants from entering the gap. This can cause leaks at the edges of the frame, and can also cause damage to the frame's surface. Contact your installer immediately if you notice any signs that your double-glazed units are leaking.

Many companies will offer a warranty on their products, and they usually include a guarantee of 10 or 20 years, some even offer lifetime assurances. Check the details of your warranty to find out what's covered and how long it lasts.

It may be worth trying to resolve any hardware issues yourself prior to calling your double glazing provider for repairs. For instance, you could try cooling the mechanism or oiling it to see if it resolves the problem. Alternatively, you can try taking the handle off or the window handle and cleaning it before putting it back in the correct position.

Check with your local council to determine whether they have any grants to help you pay for the replacement or repair of your double-glazed windows. There are many ways to apply, and some areas may require proof of eligibility or a specific type of application. It is worthwhile to check with the local authority to find out what they need to know.
