How to Repair Double Glazing Windows
If you have double-glazed windows there are times when you might encounter problems with the handles, hinges and gaskets. It is possible to fix these problems without having to replace the entire window, thereby saving time and money.
A common issue is condensation that has accumulated in the gap between the two panes of glass. This is usually an indication that the window is damaged and requires attention.
1. Broken Panes
A double pane window that is broken is a major issue and could expose your home to the elements. It is not always necessary to have the entire sash of the window to be replaced in order to resolve this issue. In fact double pane windows are usually able to be repaired with the use of a special adhesive that is inserted into the cracks to prevent them from getting worse.
This short-term solution is used to prevent superficial fractures (such stress cracks) which can develop when temperature changes cause the glass to shrink and expand. If your glass has been damaged you may have to take it off and replace the entire window.
Sometimes, the seals between two glass panes can become damaged or worn out, causing condensation and misting on the windows. These problems are typically caused by moisture trapped between the glass panes or is absorbed into the wall through the window frame. Moisture is not good for double-glazed windows regardless of the source. It can cause water damage and mold which is expensive to repair.
You can try to control the issue by wiping your double-glazed windows with cold, lukewarm water. This may temporarily fix the problem, particularly in the case of warm and humid outside. You can also employ the help of a dehumidifier in cooling the room by using double-glazed windows. This is particularly useful in the summer months.
If the issue continues, an expert in double glazing can come to your home and clean the space between the panes of glass. They can also use tools to create a line of score around the perimeter of your windows. This is where you can cut the glass with a glass cutter (inexpensive ones can be found in hardware stores). After that, take out all glazing points from the window opening. It is best to do this while the sash stays in place. However it is much easier to work on flat surfaces, such as tables.
2. Seals
The window seal is an integral element of double glazing and plays a vital function in keeping your home efficient safe, draught-free and secure. The seal is situated on the inner perimeter of uPVC frames and forms an airtight seal within the space between the two panes of glass. The seals are a vital element of double glazing's insulation. If they fail or experience problems, this will be reduced.
If your seals aren't performing their job, you'll notice condensation between the panes. It's not just ugly but it can also cause damp and mould in the home. It can cause damage to floors, furniture, walls and cause serious health issues for those suffering from respiratory ailments such as asthma.
The good news is that most double glazing manufacturers offer the option of repairing windows without replacing the entire unit. This isn't just cheaper and more affordable, but it could be a quicker and greener alternative. There are other DIY alternatives, like caulking for leaks and moisture intrusion, or self-adhesive seals that can be placed directly on the junction of the window sash with the frame.
Calling a professional is the most convenient and effective solution to a failed window seal. They can replace the window seal and prevent moisture and air from entering your home, which could cause costly damage.
Check the warranty period on your double glazing. It is usually between 10 and 20 years. This can save you money in the event that seals are broken and the windows need to be replaced. Some installers will even drill holes in misted double glazing and draw out the moisture to form a new seal and prevent it from misting in the future. However, this can be a short-term fix and a plug will need to be placed in the hole in order to keep it shut.
3. Locking Mechanisms
Double-glazed windows utilize air gaps between the glass panes as insulation against the changing temperature outside and to keep warm in the home. This type of window is also known as an IGU or insulated glass unit (IGU). They can give you a lot of energy efficiency, which can lower your heating costs. However, they are not durable and there are some issues that could arise that require double glazing repairs .
The majority of these issues are simple to fix and are much less expensive than replacing the entire window. It is recommended to contact a specialist firm that provides double glazing repair services to ensure that the repair is done correctly and with minimal effort. These companies will often provide an estimate for free to let you compare the prices and the quality of their work.
It is important to check the warranty included with your double-glazed windows, as this will usually pay for a repair. This is a standard feature of double-glazing installations and usually lasts from 10 to 20 years, however some companies offer lifetime guarantees.
If you cannot open your double glazed window or it appears there is a cloud of mist between the panes, it is probably because the seal has blown. This can occur when the frame of the window shifts slightly, or if the packaging that holds the glass sheets in place becomes damaged with time.
There are ways that you can fix double-glazed windows yourself, however it is normally far easier to use an expert company. Always follow the directions of the manufacturer and use the right tools. It is important to keep in the mind that if you attempt to remove the glass yourself, you'll lose any guarantee you might have and could end up paying a higher cost than if simply made contact with the company from whom you purchased your windows.
Once the broken pane is removed, you can replace it with plastic spacers to make sure that it fits into the frame. You can also add any uPVC beading. You can then fit a new gasket and secure the window.

They can be purchased at a hardware store or on the internet and they are a breeze to install. If you do not have the time to do it yourself, you can always hire a professional to do it for you.
If you notice condensation between your window panes, it is also something that can be easily fixed. It usually happens due to an unsound seal, which will allow moisture to enter the gap between the glass panes. This could cause the glass to cloud up, which can be ugly and ineffective.
One solution is to replace the gaskets, which can be done easily at home by anyone with a minimal DIY background. Gasket sealer is essential for a good seal, and will help reduce the cost of energy. Alternately, you can use a calk for filling any cracks and give your windows an extra boost in weatherproofing.
