How to Repair Double Glazing Windows
If you have double-glazed windows, you may sometimes experience problems with the handles, hinges and gaskets. These issues can be resolved without needing to replace your windows completely, saving your time and money.

Condensation can form in the space between the two panes. This is a sign the window requires to be repaired.
1. Broken Panes
A double pane window that is broken is a serious issue and can expose your home to the elements. But, it's not always necessary to replace the entire window sash in order to fix this problem. In fact, double pane windows are often able to be repaired with the use of a specific adhesive that is inserted into the cracks to stop them from worsening.
This repair method is typically used to stop superficial cracks (such as stress cracks) from becoming worse and can happen when temperature fluctuations cause the glass to expand and contract. If your glass has been damaged, you may need to remove and replace the entire window.
Sometimes, the seals between two glass panes may be damaged or worn out causing condensation and misting of windows. Most often, these issues result from moisture that is trapped between the two panes of glass or dripping through the window frame into the wall. Moisture is a problem for double-glazed windows regardless of the source. It can cause mold and water damage that is costly to fix.
To get the misting or condensation problem under control, you should first try wiping your double glazed windows with cold water. This can help to temporarily solve the issue, especially if the weather is warm and humid. You can also try using a dehumidifier in the room where your double glazed windows are that can be especially beneficial during summer.
If the problem persists the double glazing expert can come to your home and clean the space between the panes of glass. A tool can also be used to make an outline around the perimeter of the windows, allowing you to cut the glass using a glass cutter. After this, remove all glazing points from your window opening. It is best to do this while the sash remains in place. However, it is easier to work on flat surfaces, such as a table.
2. Seals
The window seal is a crucial component of double glazing. It plays a significant role in keeping your home energy efficient, draught-free, and safe. The seal is situated on the inner perimeter of uPVC frames and forms an airtight seal in the space between the two panes of glass. The seals form an essential component of double glazing's insulating properties. If they fail or experience problems, this will be reduced.
If the seals you have installed aren't doing their job, you'll see condensation between the panes. This isn't just ugly but can also lead to dampness and mould in the home. The effects of mould and damp can cause damage to walls, floorboards as well as furniture. It can cause serious health issues for those with respiratory issues like asthma.
The good news is that most double glazing manufacturers will offer repair services for windows without having to replace the entire unit. This isn't just cheaper and more affordable, but it could be a quicker and more environmentally friendly alternative. In the meantime, there are a few DIY alternatives, such as caulking to stop water leaks and moisture penetration, or lengths of self-adhesive seals which can be applied directly to the window frame's junction sash and frame.
Calling a professional is the most convenient and effective solution to a failed window seal. They can repair the window seal and stop air and moisture from entering your home, which could cause expensive damage.
It's worth checking the paperwork of your double glazing to see whether it comes with an assurance period of 10 to 20 years is typical and can save you money if the windows require replacement because of broken seals. Some installers will drill the misted double glazing in order to remove the moisture and then create a new seal. This will stop it from misting in the future. This is a temporary fix, and a plug must be put in to seal the hole.
3. Locking Mechanisms
Double-glazed windows use air gaps between the glass panes as insulation against temperature fluctuations outside and also to keep heat in the house. This kind of window is also known as an insulated glass unit (IGU). These windows can save money on heating costs by reducing the energy consumption. But, they're not indestructible and some problems may arise that require double glazing repairs .
Luckily, most of them are easy to fix and cost less than replacing the entire window. If you contact a company that provides double glazing repair can ensure that the work is done correctly and with minimal fuss. These companies will often provide an estimate free of charge to let you compare the prices and quality of their work.
Make sure you check the warranty that came with the double-glazed window. It usually covers the costs of repairing. This is a standard feature of double glazing installations and typically lasts for 10 to 20 years, however some companies offer lifetime guarantees.
If you are unable to open your double glazed window or it appears that there is a cloud of mist between the panes, it is likely because the seal has failed. This could happen when the frame of the window shifts slightly, or if the container that keeps the glass sheets in place becomes damaged with time.
You can repair double-glazed windows yourself, but it's usually more cost-effective to hire a professional. You should always follow the instructions of the manufacturer and make use of the right tools. You also risk voiding any warranty if you try to take off the glass by yourself. You may end having to pay more than if the company you bought the windows had just called you.
After the broken pane has been removed, you can put it back with plastic spacers, making sure that it fits into the frame and add any necessary uPVC beading. Then you can fit the gasket of a new wedge and secure the window in its place.
4. Weatherproofing
There are ways to fix double glazing windows that are difficult to open, or that have become sagging. Oiling the hinges, handles, or mechanisms to see if it helps. Another thing you can try is to replace the gaskets, which will improve the performance of your windows, and also stop them from letting in draughts or cold air. They can be purchased at a hardware store or online and they are a breeze to install. If you aren't able to tackle this task yourself, you could always have a professional do it for you.
Condensation in window panes is another issue that can be fixed easily. This is usually caused by a broken seal that allows moisture to get in the gap between the glass panes. This can cause mist to form on the glass, which is ugly and ineffective.
Anyone with a little DIY expertise can easily change the gaskets. It is crucial to make sure that you make use of a gasket sealer which will give you a strong seal and will help lower energy costs. You can also apply an elastomer to fill any cracks. This will give your windows an additional boost of weatherproofing.
The seals can also fail on double-glazed windows. This could be due to paint being used near the windows, property renovations or general wear and wear and tear. If you notice that your double-glazed windows have become misted, it is important to get them fixed as soon as you can.
