How to Repair Double Glazed Windows
Many homes with double-glazed windows are plagued by problems like condensation, a decline in insulation and windows that become difficult to open. These problems are typically a result of a fault with the hinges, mechanisms, or handles.
It is possible to fix these windows by following a few simple steps.
Cracked Panes
If a double-pane windows is damaged, it's a major issue that needs to be addressed immediately. If a double- or triple-pane window cracks the gas that insulates it will keep out cold air and warm air during winter escapes. This means that your home is less insulated. Cracks also worsen over time, so repairing them early can prevent a more serious issue in the future.
The most important step to take when a crack appears is to determine the cause of it. The most commonly cited reason is a structural problem that can lead to the crack, but it's also possible that it was caused by an impact of some kind. In this situation it's imperative to inspect the rest of your windows for damage and determine what steps you should take.
It's also recommended to check the area around your home for any other issues that could be causing the crack. If your windows are situated near other doors or walls, the stress caused by temperature fluctuations may cause cracking.
There are many ways to fix a crack depending on the cause. If the crack was caused by an impact, you may be able to replace the damaged glass. In other cases, you may have to replace the entire window frame. This is a more complex solution and requires the assistance of a professional.
If you've got 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 fracture and prevent further damage to your window.

Condensation Build-Up
Condensation build-up in between the two panes of double glazing is among the most frequent reasons homeowners need to repair their windows. It is usually a sign that a seal between the two panes of glass has failed, allowing water get in. This water vapour can cause 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 separated from the frame by a spacer bar, which acts as an insulator to help keep heat from escaping. In many cases the spacer bar has silica gel that is effective in preventing moisture from getting between the glass panes.
It is therefore essential to clean and regularly clean your windows. This will reduce the amount of moisture that is accumulated and let it evaporate. Ventilation fans and opening windows can help remove excess moisture.
Another method to fight condensation is to install a dehumidifier inside your home. These units are priced between PS60 and PS150. They are an excellent investment that not only prevents mould growth but also reduces condensation.
Condensation between the glass panes of your double-glazing may happen because the outside air is colder than that of the inner window pane, causing the surface to cool down and form condensation. It could also happen when you change the temperature of your home, for instance by switching off or turning on the heating.
Unfortunately, condensation can also be an indication of a weak double glazing structure as some of the older models are constructed with rubber strips instead of the more modern silicone variety, which can deteriorate over time. It may be possible to repair your seals, but this is only a temporary solution, as the window will eventually fail in another area.
Stained Glass
It is possible to repair a double-glazed window handle locking mechanism rather than replace the entire pane of glass. However, this isn't necessarily a DIY job since specific tools are required to ensure that the repair is done correctly and does not compromise the seal or the purpose of the window.
The most frequent complaint from upvc doors repair double glazing owners is that their windows or doors are becoming difficult to open and close. This can be caused by some slight warping of the frame or hinges however it could also be a problem with the seal. It could be that the issue is more serious and you should speak to an expert to discuss the possibilities.
Another common complaint is the formation of condensation between glass panes. This could indicate that the seal is failing and not able to hold in the gas that is insulating between the panes. This is an easy fix. The gas that is insulating can be repaired by using a special glue to seal the gap.
Start by placing the faulty window on a flat work surface. Carefully peel back the black sealant, revealing the silver spacer bar. cut into it with a sharp blade making sure to stay beneath the base of the glass and the silver spacer bar. Cut until you are able to cut the two pieces apart and after you've done this, place the top piece of glass onto your work surface (it is best to wear gloves here). Clean the glazed side that faces the frame and the spacer frame. Be sure to clean away any smears or marks, because they can impact the seal of the window when it is rebuilt. Finally, place the new bar onto the glass pane and apply adhesive on its edges to ensure it bonds to the glass and silver spacer frame. Let the adhesive dry before assembling. It is recommended to have two people do this job since it may be difficult to align everything.
Gasket Seals
Double glazing is designed to last many years, but there are still some issues that may arise. It is essential to fix any problems immediately when they arise, whether it's draughts or issues with opening and closing.
One of the most common problems faced by double-glazed owners is condensation forming between the two glass panes. It is usually due to an issue with the desiccant which absorbs moisture from the air within the space that is insulated. When the desiccant fails the condensation will form within minutes and leave a dark mark on the window.
Another issue can arise when the gasket seal is not able to stop water and other contaminants from entering the insulated gap. This can cause leaks around the edges of the frame, and can also damage the surface of the double glazed unit itself. If you observe any indications of a leak in your double-glazed units, it is essential to contact your installer as soon as possible.
Many companies will offer a guarantee on their products and these often include a guarantee period of 10 or 20 years, and some even provide lifetime assurances. It is important to check the specifics of your guarantee to see what it covers and until when it expires.
You may want to test and solve any hardware issues yourself prior to making contact with a double glazing company. For instance, you can, try cooling or lubricating the mechanism to determine if that fixes the problem. You can also try cleaning the handle or window handle before installing it.
