10 Factors To Know About Repair Double Glazing You Didn't Learn At School
How to Repair Double Glazed Windows

Many properties with double glazing are plagued by problems like condensation, a decline in insulation and windows that become difficult to open. These issues are usually a result of a problem with the hinges, mechanisms, or handles.

It is possible to fix these windows by following a few simple steps.

Cracked Panes

If a double-pane window has damaged, it's a major problem that needs to be addressed quickly. Triple- and double-pane windows are insulated using gases that keep warm air in the winter and cold air out. Therefore, when one of the panes cracks the gas escapes and your home is less protected. Cracks can also get worse over time. Repairing them now can prevent a more serious issue in the future.

When a crack occurs the most important step is to determine the cause of it. It's possible that a collision or structural issue caused the crack. In this case, it's important to check the rest of your windows for damage and to determine the best course of action to take.

It is also important to look at the area around your home to see if there are any other issues that could be causing. If your windows are near other doors or walls the stress caused by temperatures can cause cracking.

Depending on what caused the crack, there are a variety of ways to repair the issue. For instance, if it was caused by an impact, you may be able to do away with replacing just the broken pane of glass. Alternatively, you might need to replace the entire frame of your window. This is a more complicated solution, and it requires the assistance of an expert.

If you have cracks in the glass that did not cause the frame to move, then it's usually simple to apply adhesive between the broken panes. This will fix the fracture and prevent further damage to your window.

Another option that is fairly easy is to cover the crack with clear tape. This doesn't offer the best look, but it will prevent drafts and bugs from getting into your home. Glass repair film is an upgrade that can be applied quickly and provides a more solid degree of protection. This is available from many double glazing companies and is well worth the investment to protect your windows.

Condensation Build-Up

Condensation build-up in between the panes of double glazing is among the most frequent reasons homeowners need to repair their windows. It's usually a sign that the seal between two windows has failed, allowing water enter. This moisture can cause condensation and other problems that could require replacement of the window.

Double glazing reduces condensation better than single panes of glass due to the fact that it has a space in between the two panes that is filled with non-toxic gases or air. The space between the glass and the window frame is separated by a spacer, which acts as an insulator. This prevents loss of heat. In many cases, the bar is filled with a silica gel, which is very effective at taking in moisture and preventing it from getting between the panes of glass.

It is therefore crucial to clean and regularly clean your windows. This will decrease the amount of moisture that is accumulated and allow it to evaporate. Opening the windows to increase air flow can help to remove moisture.

Another way to stop condensation is to install a dehumidifier in your home. These units are available for between PS60 and PS150. They are a fantastic investment that not only prevents mould growth but also reduces condensation.

Condensation can occur between the glass panes in your double glazing as the outer air may be cooler than the interior pane. This causes the surface of the glass to cool and create condensation. It could also happen when you have an increase in temperature, such as turning on the heating or cooling of your home.

Unfortunately, condensation can also be an indication of a poor double glazing design because some older units are made with rubber strips instead of the more modern silicone version that can degrade over time. It is possible to fix your seals, but this is only a temporary solution since the window will eventually fail in a different location.

Stained Glass

It is possible to repair a double-glazed window handle locking mechanism rather than replace the entire glass pane. But, this isn't always a do-it-yourself project as specific tools are required to ensure the repair is done in a way that will not affect the seal or function of the window.

The most common complaint of homeowners of double glazing is that their windows or doors are becoming difficult to open and close. This can be caused by an occasional warping in the frame or hinges, but it can also be due to a problem with the seal. It is possible that the problem is more serious and you should speak to an expert to discuss your possibilities.

upvc window repairs near me is the development of condensation between glass panes. This could be a sign that the seal is failing and is not able to hold the gas that insulates between the panes. It is also an easy fix. The gas insulating the panes can be replaced by using an adhesive designed specifically to seal the gap between the panes.

Start by placing the faulty window on a flat work surface. Peel off the black sealant carefully to reveal the silver spacer bars. Cut into these with a sharp knife, staying at the lower end of both the glass and the spacer bars. Cut until you are able to cut the two pieces apart and when you've completed this, place the top piece of glass on your work surface (it is best to wear gloves when working with glass). Clean the glazed side that faces the frame and the spacer frame. Be sure to remove any smears or marks, as they could impact the seal of the window when it is put back together. Finally, place the new bar onto the glass pane and apply adhesive around its edge to aid in bonding it to the glass and silver spacer frame. Let it set before reassembling. This is typically a task for two people as it can be difficult to align everything.

Gasket Seals

While double glazing is durable and is designed to last for years to be, there are problems that can occur from time to time. It is essential to fix any problems immediately when they arise whether it's draughts, or problems with opening and closing.

Condensation between the two panes is one of the most frequent issues that double-glazed owners report. This is typically caused by an issue with the desiccant, which absorbs moisture from the air inside the gaps that are insulated. Once the desiccant has failed, condensation can develop in minutes and cause dark lines across the windows.

Another issue that could arise is when the gasket seal is not able to keep water and other contaminants out of 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 notice any signs that your double-glazed units are leaking.

Many companies will offer a guarantee on their products and these often come with a guarantee period of 10 or 20 years, and some even offering lifetime guarantees. It is important to check the details of your guarantee to find out what it covers and until when it expires.


You may want to try and solve any hardware issues yourself prior to contacting a double glazing supplier. For instance, you could try cooling the mechanism or oiling it to see if that resolves the problem. You can also try cleaning the handle or window handle before installing it.

Check with your local council to find out if they offer any grants to assist you in the replacement or repair of your double-glazed windows. There are many ways to apply, and some areas might require evidence of eligibility or a specific form of application. It is worth checking with your local authority to determine what they need to know.
