How to Repair Double Glazed Windows
Many homes with double-glazing encounter issues like condensation, reduction in the insulation quality and windows that are difficult to open. These issues are usually the result of a problem with the hinges, mechanisms or handles.
It is possible to fix these windows by following a couple of simple steps.
Cracked Panes
A double-paned window that has damaged is a serious problem that needs to be addressed immediately. When a double or triple-pane window is damaged, the gas that insulates it is unable to block cold air and warm air in winter escapes. This means that your home is less insulated. Cracks can also become worse as time passes. Repairing them now can prevent a more serious problem in the future.
The most important thing to do when a crack appears is to determine the cause of it. It's possible that an impact or structural issue led to the crack. In this situation, it is important to examine your other windows for damage and determine the next steps.
You should also inspect the area around your home to determine whether there are any other problems that could be causing. If your windows are near other doors or walls the stress resulting from temperature fluctuations may be causing cracking.
There are several ways to fix a crack depending on the cause. If the crack was caused by an injury, you might be able replace just the broken glass. It could be necessary to replace the whole window frame. This is a more complex solution that requires expert assistance.
If you've noticed cracks in your glass that did not cause the frame to shift, then it's generally easy to apply adhesive between the broken panes. This will repair the fracture and prevent further damage to your window.
Another option that is fairly easy is to cover the crack with clear tape. It's not the most appealing appearance, but it can stop bugs and drafts from entering your home. Glass repair film is an upgrade that can be applied quickly and offers a more sturdy level of protection. This is available from many double glazing companies and is well worth the investment to protect your windows.
Condensation Build-Up
Double glazing windows needing to be repaired are usually because of condensation between the panes. This is because it usually indicates that the seal between the panes of windows has been breached which allows water vapour to enter. This water vapour can cause condensation and other issues that could require the window to be replaced.
Double glazing is more effective at reducing condensation than single panes of glass because it has a space between the two panes which is either filled up with non-toxic gases or air. The space is then separated from the window frame by a spacer bar, which acts as an insulation to prevent heat loss. In many cases the spacer bar is made up of silica gel that is effective in preventing moisture from getting between the glass panes.
It is therefore important to clean and regularly clean your windows. This will reduce the amount of moisture that builds up and let it evaporate. Utilizing extractor fans or opening the windows to allow for more air flow can help remove excess moisture.
Another method to fight condensation is by installing a dehumidifier inside your home. These units are priced between PS60 and PS150. They are a fantastic investment that will not only stop mould growth, but also helps to reduce condensation.
Condensation between the glass panes of your double glazing may happen because the outer air is colder than that of the inner window pane, causing the surface to cool and form condensation. It can also occur when you alter the temperature in your home, for instance by turning off or 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 some cases it's possible to have your seals replaced however it's worth noting that this will only be an immediate solution since the window will eventually break down in a different area, which means you'll have to replace it in the future.
Stained Glass
It is possible to repair a double-glazed window handle or locking mechanism instead of replacing the entire glass pane. But, this isn't necessarily a DIY job since special tools are required to ensure the repair is done correctly and doesn't compromise the seal or the purpose of the window.
The majority of homeowners who have double glazing complain that their windows or doors are difficult to open. This is usually due to some slight warping of the frame or hinges but can also be due to problems with the sealing. In some instances, the issue could be more severe than this and it is worth speaking to a professional about the options available.
Condensation between glass panes is a different complaint. This could be an indication of a faulty seal that is not retaining the insulating gases between the glass panes. Again, this is an easy fix. The gas that insulates can be restored by using a special adhesive to seal the gap between the panes.
Place the window that has been damaged on a flat surface. Peel back the black sealant carefully to reveal the silver spacer bars. Cut these into pieces with a sharp knife. Keep your cut at the lower end of both the glass and the silver spacer bars. Cut until you can cut the two pieces apart and once you have done this, place the top piece of glass onto your work surface (it is recommended to wear gloves here). Once again thoroughly clean both the glazed surface that is facing into the frame and the spacer frame taking particular care to remove any marks or smears since they can affect the seal when the window is reassembled. Lastly, position the new spacer bar on the glass pane and apply adhesive around its edge to help it bond to the glass and the silver spacer frame. Allow the adhesive to dry before assembling. This is usually a task for two people as it can be tricky to get everything lined up.
Gasket Seals
While double glazing is durable and is designed to last for many years to come, there are still issues that can arise occasionally. From draughts, to problems in closing or opening it is essential to have any faults fixed as soon as possible to prevent them from getting worse.
Condensation between the two panes is one of the most frequent issues that owners of double-glazed windows report. This is typically caused by an issue with the desiccant that absorbs moisture from the air within the insulated gap. Once the desiccant fails the condensation will form within minutes and leave a dark mark on the window.
Another issue that may arise is when the gasket seal is not able 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 immediately if you spot any signs that your double-glazed units are leaky.
Many companies will offer a guarantee on their products and these often include a guarantee of either 10 or 20 years, some even offer lifetime assurances. Examine the specifics of your warranty to see what is covered and how long it lasts.
It may be worth trying to solve any hardware problems yourself before calling your double glazing provider to request repairs. You can, for example, try cooling or lubricating the mechanism to see whether it solves the issue. You can also try cleaning the handle or window handle before installing it.
Contact your local council to determine if double glazing upvc windows they offer any grants to help you pay for the replacement or repair of your double-glazed windows. There are many different ways to apply, and some areas will require a particular form of application or proof of eligibility, so it is always worth checking with your local authority before deciding on how to proceed.
