How to Repair Double Glazed Windows
Many homes with double-glazed windows experience problems such as condensation, a drop in insulation quality and windows that become difficult to open. These issues are usually a result of a defect in the hinges, mechanisms, or handles.
You can 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. If a double- or triple-pane windows cracks the gas that seals it will keep out cold air and warm air in winter escapes. This means that your home is less insulated. Cracks can get worse with time, so repairing them now prevents a potentially more serious issue in the future.
The most important thing to do when a crack appears is to determine the cause of it. The most commonly cited cause is a structural issue which can cause the break, but it's possible that the cause was an impact of some sort. In this situation, it is important to inspect your other windows for damage in order to determine the next steps.
It's also recommended to check the area around your home for any other problems that could be contributing to the crack. For instance, if your windows are situated near walls and doors, the stress of contraction and expansion caused by temperature fluctuations could cause cracking.
There are a variety of ways to fix a crack depending on the cause. For example, if it was caused by an impact, you might be able to get away by replacing only the broken pane of glass. You may need to replace the whole window frame. This is a more involved solution, and it requires the help of a professional.
If you've got cracks in your glass that didn't cause the frame to shift, then it's generally easy to apply adhesive between the broken panes. This fixes the crack and protects your window from future problems, so it's definitely worth trying in this instance.
Another option that's fairly simple is to cover the crack with clear tape. It's not the prettiest solution, but it does stop bugs and drafts from getting into your home. An alternative is the glass repair film which is designed to be quickly applied and offers greater protection. Many double glazing companies offer this product, which is worth the investment to protect your windows.
Condensation Build-Up
Condensation that builds up between the panes of double-glazing is one of the most common reasons why people need to repair their windows. It is usually a sign that a seal between two window panes failed, allowing water to be able to. This can lead to condensation, as well as other issues which may require replacement of the window.
Double glazing is superior in lessening condensation than single pane windows because it has an air space between the glass that is either filled with air or gas that is not toxic. The space between the glass and window frame is separated by a spacer, which acts as insulator. This prevents loss of heat. In a lot of cases, the spacer bar is filled with a silica gel, which is very effective at picking up 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 forms and allows it to evaporate. Utilizing extractor fans or opening the windows to increase airflow can also help to remove moisture.
Another way to combat condensation is to install an air dehumidifier in your home. These units are priced between PS60 and PS150. They are a fantastic investment that not only prevents mould growth, but also helps to reduce condensation.
Condensation can happen between the glass panes of your double glazing because the outer air may be warmer than the inside window pane. This causes the glass's surface to cool and produce condensation. It could also occur when you alter the temperature in your home, for example by switching off or turning on the heating.
Unfortunately, condensation can also be an indication of a poor double glazing design as some of the older units are constructed using rubber strips instead of the more modern silicone variety which may degrade over time. In certain cases it's possible to have your seals replaced but it's important to note that this is only an immediate solution since the window will eventually fail in another area, meaning you'll have to replace it in the future.

Stained Glass
It is possible to repair the double-glazed window handle or locking mechanism, rather than replacing the entire glass pane. This isn't a straightforward DIY project, as you will need special tools to ensure that the repair is carried out correctly.
The majority of homeowners who have double glazing complain that their doors or windows are difficult to open. This is usually due to a slight warping of the frame or the hinges but can also be due to issues with the sealing. In some cases the issue may be more severe than this and it is recommended to speak to a professional regarding the options available.
Another issue that is frequently reported is the forming of condensation between the glass panes. This could be a sign that the seal is failing and no longer holding in the insulating gas between the panes. This is a simple fix. The insulating gas can be repaired by using special glue to fill the gap.
Place the damaged window on a flat surface. Carefully peel back the black sealant, revealing the silver spacer bar and cut into it using a sharp knife, making sure to stay below the base of the glass and silver spacer bar. After you've separated the two pieces, put the top glass pane on your work surface. It is recommended to use gloves for this step. 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 put back together. Finally, place the new bar onto the glass pane, and spread adhesive on its edges to help it bond to the glass and the silver spacer frame. Let the adhesive dry before reassembling. This is typically a task for two as it can be difficult to get everything lined up.
Gasket Seals
Although double glazing is extremely durable and designed to last for a long time to be, there are problems that can occur from time to time. From draughts to problems in closing or opening it is crucial to address any problems quickly to prevent them from getting worse.
Condensation between the two panes is among the most frequent issues that double-glazed owners have to deal with. It is usually due to an issue with the desiccant which absorbs moisture from the air within the space that is insulated. If the desiccant is not working it can cause condensation to form within minutes and leave a dark mark on the window.
Another problem that can occur is when the gasket seal fails to keep water and other contaminants from the gap between the insulated gaps. This can cause leaks around the edges of the frame and can also damage the surface of the double glazed unit itself. Contact your installer right away if you observe any signs that your double-glazed units are leaky.
Many companies offer a warranty for their products. These warranties often include a guarantee of 10, or even 20 years. repairmywindowsanddoors.co.uk provide lifetime guarantees. Examine the specifics of your warranty to find out what's covered and how long it will last.
It might be worthwhile trying to resolve any hardware issues yourself prior to calling your double glazing provider to request repairs. For instance, you can try cooling or lubricating the mechanism to determine whether it solves the issue. You could also try cleaning the handle or window handle prior to reinstalling it.
It is also important to check whether your local council has insulation grants to assist in the replacement or repair of your double glazed windows. There are a variety of ways to apply, and some areas might require the proof of eligibility or a specific form of application. It is worth checking with your local authority to see what they need to know.
