How to Repair Double Glazed Windows
Many homes with double-glazed windows have issues like condensation, a drop in insulation and windows that are difficult to open. These problems are usually caused by an issue with the handles or hinges.
You can fix these windows in a couple of easy steps.
Cracked Panes
A double-paned window that has cracked is a serious issue that needs to be dealt with immediately. When a double or triple-pane window is damaged the gas that insulates it to 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 can prevent a bigger problem in the future.
The most important step to take when a crack appears is to determine what caused it. The most common reason is a structural issue that could cause breakage, but it's also possible that the cause was an impact of a different kind. In this case it is imperative to inspect your other windows for damage in order to determine the next steps.
It is also important to look at the area around your home to see if there are any other problems that could be contributing. If your windows are located near walls or doors the stress resulting from temperatures can be causing cracks.
There are many ways to fix a crack depending on the source. If the crack was caused by a blow, you may be able replace just the broken glass. Or, you may need to replace the entire window frame. This is a more complex solution that requires professional assistance.
If you've noticed cracks in the glass that didn't cause the frame to move then it's generally easy to apply adhesive between the broken panes. This will repair the crack and preserves your window from future problems, so it's certainly worth a try in this instance.
Covering the crack with clear tape is a different option. This doesn't offer the best appearance, but it does prevent drafts and bugs from getting into your home. The next step is a glass repair film made to be easily applied and offers more durable protection. This is available from many double glazing companies and is worth the investment to secure your windows.
Condensation Build-Up
Condensation build-up in between the two panes of double glazing is one of the most frequent reasons people need to repair their windows. It's usually a sign that the seal between the two panes of glass has failed, allowing water be able to. This can lead to condensation, as well as other issues that could require replacement of the window.
Double glazing can reduce condensation better than single panes of glass because it has a space in between the two panes that 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 insulator and helps stop heat loss. In many cases, the spacer bar is filled with silica gel which is extremely effective in taking in moisture and preventing it from entering between the glass panes.
It is therefore crucial to regularly wipe down and clean your windows. This will decrease the amount of moisture that builds up and allow it to evaporate. Using extractor fans or opening the windows to allow for more airflow can also aid in removing excess moisture.
Another way to stop condensation is to install a dehumidifier inside your home. These units can be picked up for around PS60-PS150 and are a great investment that will not only reduce condensation but prevent mould growth within your home, too.
Condensation between the glass panes of your double-glazing may happen because the outer air is colder than the inner window pane, causing the surface to cool down and create condensation. It can also happen when you have a change of temperature, for instance, turning on the heating or cooling in your home.
Condensation is also an indication of poor double glazing as older units were made with rubber strips, rather than the current silicone version. They can become damaged over time. In certain cases it's possible to repair your seals, although it is worth noting that this will only be the short-term solution as the window will eventually fail in a different area, which means you'll need to replace it in the future.
Stained Glass
If you are having issues with a double-glazed window handle or lock, it is often possible to repair it instead of having to replace the entire glass pane. This isn't a straightforward DIY task, as you will need special tools to ensure that the repair is done right.
The most frequent complaint from owners of double glazing is that their doors or windows have become difficult to open and close. This can be due to some slight warping of the frame or hinges but it can also be a problem with the seal. It could be that the issue is more serious and you should speak to a professional to discuss the possibilities.
Another frequent complaint is the formation of condensation between the glass panes. This could be an indication of a faulty seal that isn't holding the gases that are insulating between the glass panes. It is also an easy fix and the gas that insulates can be restored with a special adhesive to seal the gap between the panes.
Start by placing the faulty window on a flat work surface. Peel off the black sealant carefully to reveal the silver spacer bars. Cut into these with a sharp knife, staying just below the bottom of both the glass and the silver spacer bars. Cut until you can cut the two pieces apart and when you've completed this, put the top layer of glass on your work surface (it is recommended to wear gloves when working with glass). Make upvc window repairs to thoroughly clean both the glazed side that is facing the frame and the spacer frame, making sure to get rid of any marks or smears as these can impact on the seal when the window is re-assembled. Lastly, position the new spacer bar onto the glass pane, and spread adhesive around its edge to aid in bonding it to the glass and the silver spacer frame. Allow to set before re-assembling. It is best to have two people assist you since it may be difficult to align everything.
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 fix any issues promptly to prevent them from becoming worse.
One of the most frequent issues reported by double-glazed owners is the formation of condensation between the two panes of glass. This is typically caused by an issue with the desiccant that absorbs moisture from the air in the space that is insulated. After the desiccant has failed, condensation can develop in minutes and form an ugly line across the windows.
Another issue that could arise is when the gasket seal fails to keep water and other contaminants out of the insulated gap. This could lead to leaks around the edges of the frame, and could also cause damage to 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 quickly as you can.
Many companies will offer a warranty on their products. These usually include a guarantee of 10 or 20 years, and some even offer lifetime guarantees. It is important to check the specifics of your guarantee to see what it covers and the date it expires.
It may be worth trying to solve any hardware issues yourself before contact your double glazing company to request repairs. For instance, you can try cooling or fluidizing the mechanism to see whether that solves the issue. You can also try cleaning the handle or window handle prior to reinstalling it.
It is also essential to determine if your local council offers insulation grants that can help pay for the replacement or repair of your double-glazed windows. There are numerous ways to apply, and some areas require a specific form of application or proof of eligibility, therefore it is always worth checking with your local authority prior to deciding how to proceed.
