How to Repair Double Glazing Windows

If you have double glazing, you may sometimes experience issues with handles, hinges and gaskets. These can often be fixed without the need to replace your windows completely, saving you time and money.

One of the most common issues is condensation accumulating in the space between the two glass panes. This is a sign that the window needs to be repaired.

1. Broken Panes

A broken double pane window is a serious issue and could expose your home to the elements. However, it's not always necessary to replace the entire window sash to resolve this problem. Double pane windows can be fixed with an adhesive that is specifically designed to be placed inside the cracks.

This short-term option is used to prevent superficial fractures (such stress cracks) which can develop when temperature fluctuations cause the glass to expand and shrink. If your glass has broken it may be necessary to remove and replace the entire window.

The seals between two panes can break or break which can cause condensation and misting on windows. Most often, these issues result from moisture that is trapped between the two panes of glass or leaks through the window frame and into the wall. Moisture is bad for double-glazed windows, no matter its source. It can cause water damage and mold, which are costly to fix.

Double Glazing Door Repairs  can try to resolve the issue by cleaning your double-glazed windows with cold, lukewarm water. This can temporarily solve the issue, especially when it is hot and humid outside. You can also employ the help of a dehumidifier in cooling the room by using double-glazed windows. This is particularly helpful in summer.

If the problem persists a double glazing specialist is able to visit your home and clean the space between the panes of your glass. A tool can also be used to create an outline of a score line around the outside of the windows, allowing you to cut the glass with a glass cutter. Once this is done then you must remove all glazing points and putty from the frame of the window opening. This is best done while the sash is still in place, however it can be easier to work on a flat surface, such as a table.

2. Seals

The window seal is an integral component of double glazing. It plays a significant function in keeping your home efficient safe, draught-free and secure. The seal is located on the inner frame's uPVC frame and provides an air-tight seal over the gas-filled space between the two glass panes of the window. This is a key component of the insulation your double glazing delivers and any problems or failures in the seals could greatly diminish the benefits.

If your seals aren't doing their job, you will see condensation between the panes. This isn't just unsightly, but it can cause dampness and mould in the home. Damp and mould can cause damage to floors, walls, and furnishings and can also have serious health implications for those with respiratory conditions such as asthma.


The positive side is that a majority of double glazing manufacturers offer the option of repairing windows without replacing the entire unit. This is not only less expensive, but also quicker and more eco-friendly. There are other DIY alternatives, like caulking to stop leaks and moisture intrusion or self-adhesive seals which can be placed directly on the junction of the window sash and the frame.

Calling a professional is the easiest and most effective way to fix a broken window seal. They'll be able to repair the window seal to prevent the infiltration of air and moisture, which can cause expensive damage and help your home remain energy efficient.

Check the warranty period on your double glazing. It's usually between 10 and 20 years. This could save you money in the event that the seals have failed and the windows must be replaced. Some installers may even drill holes into misted double glazing and draw out the moisture in order to create an entirely new seal, and stop it from leaking again in the future. But, this could be a short-term fix and a plug will need to be put into the hole to keep it closed.

3. Locking Mechanisms

Double glazed windows utilize gaps of air between glass panes in order to insulate against varying outside temperatures and to help keep heat in the house. This kind of window could also be called an insulation unit (IGU). They can provide you with a lot of energy efficiency which saves on your heating costs. They aren't indestructible and may require repair to the double glazing.

Most of these problems are simple to fix and are less expensive than having to replace the entire window. It is best to contact a specialist firm that provides double glazing repair services to ensure that the repair is carried out correctly and with minimal fuss. Often these companies will provide an estimate for free to allow you to compare prices and the quality of their work.

It is important to check the warranty that came with your double glazed window, as this will usually pay for a repair. This is a common feature of double glazing installations and usually lasts from 10 to 20 years, although some companies offer lifetime guarantees.

If you cannot open your double-glazed windows or it appears as if there is mist between the panes then this could be due to the seal blowing. This could occur if the frame of the window moves in a slight manner, or when the packing that holds the glass sheets in place deteriorates with time.

You can repair double-glazed windows yourself, but it's usually simpler to employ a professional. You should always follow the directions of the manufacturer and employ the correct tools. It is important to keep in mind that if you attempt to remove the glass by yourself, you'll lose any warranty you may have and could end up paying a higher cost than if you simply made contact with the company from whom you bought your windows.

After you have removed the broken glass then you can replace it with plastic spacers. This will ensure that the replacement is a good fit for the frame. You can also add any uPVC beading that is required. Then, you can install an additional gasket and seal the window.

4. Weatherproofing

If your double glazing windows are difficult to open or are sagging there are methods of fixing them. For instance, you can try oiling the hinges, mechanisms or handles to see if this aids. You can also change the gaskets to improve your windows' performance and stop them from letting in cold air and draughts. These are available at a hardware shop or on the internet. They are easy to install. If you don't have the time to do it yourself, you could always hire a professional to complete the task for you.

Condensation in window panes is another problem that is easily fixed. 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 develop on the glass, which is both undesirable and ineffective.

One solution is to replace the gaskets, which can be done easily at home by anyone with a little DIY experience. Gasket sealer is crucial for a good seal, and can reduce energy bills. Alternatively, you can use a calk to fill any cracks in your windows and give them an extra boost in their weatherproofing.

Another issue that is common to double-glazed windows is that the seals break down. This can be caused by paint being applied 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 crucial to have them repaired in the earliest time possible.

Double glazed windows can be an excellent addition to your home, providing you with energy efficient and secure windows that keep the cold out and the heat in. However, there are times when it is better to replace your double glazed windows, rather than repair them. This could include completely broken panes, extensive rot and frames that are no longer suitable for the double glazing units.
