20 Fun Details About Repair Double Glazing
How to Repair Double Glazed Windows

Many properties with double glazing experience problems such as condensation, a drop in the quality of insulation and windows that are difficult to open. These problems are typically a result of a defect in the hinges, mechanisms or handles.

It is possible to repair these windows by following a few easy steps.

Cracked Panes

A double-paned window that has damaged is a major issue that must be addressed immediately. Double- and triple-pane windows are insulated using gases that ensure warm air is kept in during winter and cold air out. Therefore, when one of these panes cracks this gas escapes and your home is less well-insulated. Cracks also worsen over time, so fixing them early 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 cause is a structural issue which can cause the breakage, but it's also possible that the cause was an impact of a different kind. In this instance, it is important to check your other windows for damage and determine the next steps.

It's also an excellent idea to look over the area around your home for any other problems that could be causing the crack. For instance, if your windows are located near to other doors and walls The stress of contraction and expansion caused by temperature fluctuations could be the cause of cracking.

There are several ways to fix a crack depending on the source. If the crack was caused by an impact, you may be able to replace the damaged glass. In other cases, you may have to replace the entire frame of your window. This is a more difficult solution that requires expert assistance.

However, if you're dealing with a crack that did not cause the frame to move, it's generally easy to simply apply an adhesive between the fractured panes. This can repair the crack and protects your window from future problems and is definitely worth trying in this case.


Another option that's fairly simple is to cover the crack with clear tape. It's not the prettiest solution, but it will stop bugs and drafts from getting into your home. An alternative is the glass repair film which is made to be easily applied and provides more robust protection. Many double glazing companies offer this product, which is worth the investment to safeguard your windows.

Condensation Build-Up

Double glazing windows that need to be repaired are often due to condensation between the panes. This is because it indicates that the seal between the two window panes has been breached, allowing water vapour to pass through. This water vapour can cause condensation and other issues that could need the window replaced.

Double glazing can reduce condensation better than single panes of glass because it has a space between the two panes which is either filled up with non-toxic gases or air. The space between the glass and window frame is separated by a spacer, which acts as insulator. This helps prevent heat loss. In many instances the spacer bar is made up of silica gel which is effective in preventing moisture from entering between the glass panes.

It is therefore important to regularly wipe down and clean your windows. This will decrease the amount of moisture that accumulates and let it evaporate. Extraction fans and opening windows can help remove excess moisture.

Installing a dehumidifier can be another option to prevent condensation. They can be picked up for around PS60-PS150 and are a great investment that will not just reduce condensation, but also prevent the growth of mould in your home, too.

Condensation can happen between the glass panes of your double glazing due to the air outside may be warmer than the inside window pane. This causes the surface of the glass to cool and produce condensation. It could occur when you alter the temperature in your home, such as by turning off or on the heating.

Condensation is also an indication of poor double glazing, since older units were made with rubber strips instead of the modern silicone variety. They can become damaged over time. In some instances it is possible to have your seals repaired however it's worth noting that this will only offer a short term solution as the window will eventually fail in a different area, which means you'll have to replace it anyway.

Stained Glass

If you're having trouble with a double glazed window handle or lock it is often possible to repair it, rather than replace the entire glass pane. This is not a simple DIY task, as you will need special tools to ensure that the repair is carried out right.

The most common complaint from double glazing owners is that their windows or doors are becoming difficult to open and close. This could be due to some slight warping of the frame or hinges but it can also be a problem with the seal. In some instances, the issue may be more serious and it is worth speaking with a professional about the options available.

Condensation in the glass panes is another common complaint. This could be an indication of a faulty seal that isn't holding the insulating gases between the glass panes. This is a simple fix. The insulating gas can be repaired by using an adhesive that is specifically designed to close the gap.

Start by placing the broken window on a flat work surface. Remove the black sealant to reveal the silver spacer bar and cut into this with a sharp blade, making sure to stay beneath the glass's bottom and silver spacer bar. Cut until you can separate the two pieces and once you have done this place the top pane of glass on your work surface (it is best to wear gloves while working). Make sure to thoroughly clean both the glazed side that faces into the frame and the spacer frame, taking care to remove any marks or smears since they could affect the seal when the window is put back together. The last step is to position the new spacer on the glass pane. Spread the adhesive along the edge to allow it to adhere to the glass and silver spacer frame. Allow it to set before reassembling. It is best to have two people do this job because it is difficult to align everything.

Gasket Seals

Although double glazing is extremely durable and is designed to last for years to be, there are problems that may arise from time to time. From draughts to problems with closing or opening, it is important to fix any issues promptly to prevent them from becoming worse.

Condensation between the two panes is among the most common problems that double-glazed owners report. This is due to the failure of the desiccant which absorbs moisture from the air in the insulated gap. Once the desiccant fails, condensation can form in minutes and leave a dark mark on the window.

Another issue could arise if the gasket seal is not able to stop water and other contaminants from leaking into the insulated gap. This can cause leaks at the edges of the frame and also damage the frame's surface. Contact your installer immediately if you spot any indications that your double-glazed units are leaky.

Many companies offer a warranty for their products. These warranties often include a period of guarantee that is 10 or 20 years. Some companies offer lifetime guarantees. Review the terms of your warranty to find out what's covered and how long it will last.

It is possible to try to solve any hardware problems yourself before calling your double glazing provider for repairs. For example, you can try cooling the mechanism or oiling it to see if this fixes the issue. You can also try cleaning the handle or window handle before reinstalling it.

It is also important to check whether your local council has any insulation grants available to help pay for the replacement or repair of your double glazed windows. There are many ways to apply, and some areas may require proof of eligibility or a specific type of application. It is worth checking with your local authority to determine what they need to know.
