How to Repair Double Glazing Windows
If you have double-glazed windows there are times when you might encounter issues with gaskets, hinges, and handles. It is possible to resolve these issues without having to replace the entire window, saving time and money.
A common issue is the accumulation of condensation in the space between the two panes of glass. This is a sign that the window must be fixed.
1. Broken Panes
A broken double pane window is a serious issue and could leave your home exposed to the elements. However, it is not always necessary to replace the entire window sash in order to address this problem. In fact double pane windows are typically repairable with the use of a specific adhesive that is inserted into the cracks to prevent them from worsening.
This short-term repair option is often used to prevent superficial cracks (such as stress cracks) from getting worse that can happen when temperature fluctuations cause the glass to expand and contract. If your glass is damaged, you may need to take it off and replace the entire window.
The seals between two panes of glass can wear away or be damaged, causing misting and condensation on the windows. Usually, these issues are caused by moisture that gets trapped between the two glass panes or dripping through the window frame into the wall. Moisture is bad for double-glazed windows regardless of the source. It can cause water damage and mold which is expensive to fix.
You can try to resolve the problem by wiping down your double-glazed windows using cold, lukewarm water. This can temporarily solve the issue, especially when it is warm and humid outside. You can also consider using a dehumidifier inside the room in which your double-glazed windows are that can be especially helpful during the summer.
If the problem persists an expert in double glazing can come to your home and clean the space between the panes of your glass. They can also use a tool to create a line of score around the perimeter of your windows where you need to cut the glass using a glass cutter (inexpensive cutters are available in hardware stores). After that, you should remove all glazing points from the window opening. This is best done while the sash is still in place, but it can be easier to work on a flat surface such as a table.
2. Seals
The window seal is an integral component in double glazing and plays a significant part in keeping your home energy efficient as well as draught-free and safe. The seal is located on the inner perimeter of the uPVC frame and provides an air-tight seal over the gas-filled space between the two panes of glass in the window. The seals are an essential component of double glazing's insulating properties. If they fail or experience problems, this will be reduced.
If your seals aren't able to do their job, the result will be condensation between the panes. This is not only unsightly however, it could also lead to dampness and mould within the home. The effects of mould and damp can cause damage to floors, walls as well as furniture. It can cause serious health issues for those with respiratory conditions such as asthma.
The good news is that most double glazing manufacturers will offer a service to repair windows without having to replace the entire unit. This isn't just less expensive, but it can be a faster and more environmentally friendly alternative. There are also DIY alternatives, like caulking for leaks or moisture intrusion or self-adhesive seals that are placed directly on the junction of the window sash and the frame.
Contacting a professional is the most convenient and effective way to fix a broken window seal. They can repair the window seal and prevent moisture and air from entering your home, which can cause expensive damage.
It is worth looking over the documentation of your double glazing to find out if it has a warranty period - 10 to 20 years is common - this could save you money if your windows require replacement because of damaged seals. Some installers drill holes into the misted double glazing to remove the moisture and create a new seal. This will prevent it from misting in the near future. But, this could be an interim fix and a plug will need to be placed in the hole to keep it sealed.
3. Locking Mechanisms
Double-glazed windows use air gaps between the glass panes for insulation against the changing temperature outside and to maintain warm inside the house. This type of window can also be described as an Insulated Unit (IGU). These windows can help you save money on heating bills by reducing energy use. They aren't indestructible and could require repair to the double glazing.
Luckily, most of these are relatively easy to fix and are much less expensive than replacing the entire window. Contacting a company that offers double glazing repair will guarantee the work is done correctly and without any hassle. Many of these companies will give you an estimate for free to allow you to compare costs and the quality of their work.
It is essential to verify the warranty included with your double-glazed windows as it will typically pay for repairs. This is a standard part of all double glazing installations and usually lasts 10 or 20 years although some companies offer lifetime warranties.
The seal could have blown if you cannot open your double-glazed window or if there appears to be mist between the panes. This could happen if the frame of your window shifts slightly or if the special packaging that holds the glass sheets gets worn out over time.
You can fix double-glazed windows yourself, but it's easier to hire a specialist. If you attempt to do it yourself, then follow the manufacturer's guidelines and use specific tools for the job. It is also worth bearing in mind that if you attempt to remove the glass yourself then you'll lose any warranty you may have and you could end up with a bigger cost than if simply called the company from which you bought the windows.
After double glazing window repairs have removed the broken glass, you can replace it with plastic spacers. This will ensure that the new glass is compatible with the frame. You can also add any uPVC beading that is required. Then you can fit an additional wedge gasket and secure the window into place.
4. Weatherproofing
If your double glazing windows are difficult to open or have sagged, there are ways of fixing them. For instance, you can try oiling the mechanisms, hinges or handles to see if this helps. Another thing that you can do is to replace the gaskets. This will enhance the performance of your windows and prevent them letting in draughts and cold air. You can get these at a hardware store, or online, and they are easy to install. You can ask for help from a professional if want to do it yourself.
Condensation between windows is another problem which can be easily solved. This is due to the window seal being damaged, which allows moisture to enter between the glass panes. This could cause the glass to mist up, which is unattractive and ineffective.
Anyone with some DIY experience can easily replace the gaskets. Gasket sealer is crucial for a strong seal and will help reduce energy bills. You can also use a calk for filling any gaps and give your windows an extra boost in weatherproofing.
The seals could also fail on double-glazed windows. This can be caused by painting the windows near them or renovation work on the property or general wear and tear. It is crucial to repair your double-glazed windows as quickly when they start to become smudged.
Double-glazed windows can be a great addition to your home, providing you with energy efficient and secure windows that keep the cold out and the heat in. However, there are instances that it is recommended to replace your double-glazed windows rather than repair them. This can include broken panes, extensive decay and frames that are not suitable for the double glazing units.
