Many properties with double glazing are plagued by problems like condensation, a drop in the quality of insulation and windows that become difficult to open. These problems are typically a result of a problem with the hinges, mechanisms, or handles.

It is possible to fix these windows by following a few simple steps.

Cracked Panes

A double-paned windows that are cracked is a serious issue that must be addressed immediately. When a double- or triple-pane windows cracks the gas that seals it will keep out cold air and warm air in winter months escapes. This means that your home is less insulated. Cracks can get worse with time, so repairing them now prevents a potentially larger issue in the future.

The most important step to take when you notice cracks is to determine the cause of it. It's possible that an impact or structural issue led to the crack. In this instance, it is important to examine your other windows for damage and determine the next steps.

It's also recommended to check the area around your home for any other problems which could be contributing to the crack. For instance, if your windows are close to walls or doors The stress of expansion and contraction caused by temperature fluctuations could be the cause of cracking.

Depending on the cause of the crack, there are different solutions to fix the issue. If the crack was caused by an impact, you may be able to replace only the damaged glass. It could be necessary to replace the whole window frame. This is a more complex solution and requires the assistance of an expert.

Double glazing windows that require to be fixed are often due to condensation between the panes. This is because it typically indicates that the seal between the panes of windows has failed and allowed water vapour to get in. This moisture can then create condensation and other issues that may require the window to be replaced.

Double glazing can reduce condensation better than single panes of glass because it has a space between the two panes that is filled with non-toxic gases or air. The space is then separated from the frame by a spacer bar, which acts as an insulation to stop heat loss. In many instances the spacer bar is stuffed with a silica gel, which is very effective at picking up moisture and preventing it from getting between the glass panes.

This is the reason it is important to clean your windows frequently and keep them clean, since this will reduce the amount of condensation that builds up and allows it to evaporate. Using extractor fans or opening the windows to create more air flow can help to remove moisture.


Another method to fight condensation is by installing a dehumidifier inside your home. These units can be picked up for around PS60-PS150 and are a good investment that will not just reduce condensation, but also stop the growth of mould within your home, too.

Condensation between the glass panes of your double glazing may happen because the outside air is colder than the inside window pane, which causes the surface to cool down and cause condensation. It can also occur when you have a change of temperature, for instance, turning on the heating or cooling your home.

However, condensation could also be an indication of a poor double glazing design since some older models are constructed with rubber strips instead of the more modern silicone version, which can deteriorate over time. It is possible to repair your seals, however this is only a temporary solution, as the window will eventually fail in a different location.

Stained Glass

It is possible to fix a double-glazed window handle or locking mechanism, rather than replacing the entire pane of glass. This isn't a straightforward DIY project, since you'll need specialized tools to ensure that the repair is done properly.

Repair My Windows And Doors with double glazing complain that their windows or doors are difficult to open. This is often caused by some slight warping of the frame or hinges, but could also be due to problems with the sealing. It is possible that the problem is more serious and you should consult a professional to discuss the options.

Condensation between the glass panes is a common complaint. This can be a sign that the seal is failing and is not able to hold the insulating gas between the panes. It is also an easy fix. The insulating gases can be reinstated by using an adhesive designed specifically to seal the gap between the panes.

Start by placing the broken window on a flat surface. Peel off the black sealant gently to reveal the silver spacer bars. Cut into these with a sharp knife. Keep your cut just below the bottom of both the glass and the spacer bars. Cut until you can split the two pieces, and after you've done this, put the top layer of glass onto your work surface (it is best to wear gloves when working with glass). Once again thoroughly clean both the glazed side that is facing the frame and the spacer frame, taking particular care to remove any marks or smears as they can affect the seal when the window is reassembled. The last step is to place the new spacer onto the glass pane. Spread some adhesive around the edge to help it stick to the glass and silver spacer frame. Let the adhesive dry before reassembling. It is recommended that two people do this job as it can be difficult to set everything in the right place.

Gasket Seals

While double glazing is highly durable and is designed to last for many years to come, there are still problems that can occur occasionally. From draughts to problems in closing or opening, it is important to have any faults fixed promptly to prevent them from getting worse.

Condensation between the two panes is among the most frequent issues that owners of double-glazed windows report. This is usually caused by an issue with the desiccant, which absorbs moisture from the air in the space that is insulated. After the desiccant has failed, condensation can develop in minutes and cause an ugly line across the windows.

Another issue could arise if the gasket seal is not able to stop water and other contaminants from leaking into the insulated gap. This can lead to leaks around the edges of the frame and can also damage the surface of the double glazed unit itself. If you notice any signs of leaks in your double glazed units it is essential to contact your installer as soon as you can.

Many companies offer a guarantee for their products. These warranties often include a period of guarantee that is 10 or 20 years. Some companies even provide lifetime guarantees. It is essential to review the specifics of your guarantee to determine what it covers and the date it expires.

You may want to try and solve any hardware issues yourself before contacting a double glazing supplier. For instance, you could try cooling the mechanism or lubricating it to see if that resolves the problem. You can also try removing the handle or window handle and cleaning it before returning it to its place.
