The Leading Reasons Why People Are Successful With The Repair Double Glazing Industry
How to Repair Double Glazed Windows

Double-glazing in many homes can cause issues like condensation, reduction in the insulation quality and windows that are difficult to open. These issues are usually a result of a fault with the hinges, mechanisms, or handles.

You can repair these windows by following a few simple steps.

Cracked Panes

If a double-pane window is damaged, it's a major problem that needs to be addressed quickly. When a double or triple-pane window is damaged the gas that seals it to keep out cold air and warm air during winter is released. This means that your home is less insulated. Cracks also worsen over time, so repairing them now can prevent a more serious issue in the future.

The most important step to take when you notice a crack is to determine what caused it. The most frequent cause is a structural issue that could cause breakage, but it's also possible that it was caused by an impact of some kind. In this instance it's imperative to inspect your windows for damage and to determine the next steps to take.

It is also a good idea to inspect the surrounding area of your home for any other issues that could be contributing to the crack. For instance, if your windows are close to walls or doors, the stress of expansion and contraction caused by temperature fluctuations could cause cracking.

Depending on what caused the crack, there are a variety of ways to repair the issue. If the crack was caused by a blow, you may be able replace just the broken glass. You may need to replace the entire window frame. This is a more difficult solution that requires expert assistance.

If you have cracks in your glass that didn't cause the frame to move, then it is usually easy to apply adhesive between the damaged panes. This will fix the crack and stop further damage to your window.

Covering the crack using clear tape is an alternative option. This isn't the best appearance, but it does keep bugs and drafts from entering your home. Glass repair film is an upgrade that can be applied quickly and provides a solid level of protection. It's available from a variety of double glazing companies and is well worth the investment to safeguard your windows.

Condensation Build-Up

Double glazing windows that need to be fixed are often due to condensation between the panes. It is usually a sign that a seal between two window panes was not strong enough, allowing water to enter. This moisture can then create condensation and other issues that may need the window replaced.

Double glazing is more effective in lessening condensation than single pane windows as it has an area between the glass which is filled with air or gas that is not toxic. The space is separated from the frame by a spacer bar, which acts as an insulation to stop heat loss. In many cases, the spacer bar contains silica gel which is effective in preventing moisture from entering between the glass panes.

This is the reason it is important to wipe down your windows on a regular basis and keep them clean since this will reduce the amount of condensation that forms and allow it to evaporate. Utilizing window contractors or opening the windows to allow for more air flow can help remove excess moisture.

Installing a dehumidifier is another way to combat condensation. These units can be picked up for around PS60-PS150 and are a great investment that will not just reduce condensation, but also stop the growth of mould in your home as well.


Condensation between the glass panes of your double glazing can occur due to the fact that the outer air is colder than the inside window pane, causing the surface to cool down and cause condensation. It could occur when you alter the temperature in your home, for example by turning off or on the heating.

Condensation is also a sign of poor double-glazing, since older units were made with rubber strips instead of the latest silicone type. They are susceptible to deterioration with time. In some instances, it may be possible to have your seals replaced but it's worth noting that this will only be an immediate solution since the window will eventually fail in another location, which means you'll have to replace it in the future.

Stained Glass

It is possible to fix a double-glazed window handle locking mechanism instead of replacing the entire pane of glass. However, this is not always a DIY project since special tools are required to ensure that the repair is done in a way that does not compromise the seal or the function of the window.

The most frequent complaint from double glazing owners is that their doors or windows have become difficult to open and close. This can be due to a slight warping in the frame or hinges, but it can also be a problem with the seal. It could be that the issue is more serious and you should speak to a professional to discuss the possibilities.

Another frequent complaint is the formation of condensation between the glass panes. This could be a sign that the seal is failing and not able to hold the gas that is insulating between the panes. This is an easy fix. The insulating gases can be reinstated with a special adhesive to seal the gap between the panes.

Begin by placing the damaged window on a flat work surface. Peel back the black sealant with care to reveal the silver spacer bars. Cut into these with a sharp knife, keeping below the base of both the glass and the spacer bars. Cut until you can cut the two pieces apart and when you've completed this, put the top layer of glass onto your work surface (it is recommended to wear gloves when working with glass). Once again thoroughly clean both the glazed surface that is facing into the frame and the spacer frame taking particular care to remove any smears or marks as these can impact on the seal when the window is reassembled. Then, put the new spacer bar onto the glass pane and apply adhesive on its edges to help it bond to the glass and silver spacer frame. Allow to set before re-assembling. This is typically a task for two since it can be tricky to align everything.

Gasket Seals

Double glazing is designed to last for years However, there are some issues that may arise. It is important to fix any problems promptly when they happen, whether it's draughts or problems with opening and closing.

Condensation between the two panes is one the most common problems that owners of double-glazed windows report. This is caused by the failure of the desiccant which absorbs moisture in the air within the space that is insulated. Once the desiccant has failed it can cause condensation to form in minutes and form dark lines across the windows.

Another problem can occur when the gasket seal fails to stop water and other pollutants from entering the gap. This can lead to leaks at the edges of the frame and can also cause damage to the frame's surface. Contact your installer right away if you observe any indications that your double-glazed units are leaking.

Many companies offer a guarantee on their products, and they usually include a guarantee period of 10 or 20 years, and some even offer lifetime assurances. It is important to check the terms of your guarantee to determine what it covers and the date it expires.

It may be worth trying to solve any hardware problems yourself prior to contacting your double glazing supplier for repairs. For example, you can try cooling the mechanism or lubricating it to see if this fixes the problem. Alternatively, you can try taking the handle off or the window handle and cleaning it prior to putting it back in place.

It is also important to check whether your local council has any insulation grants available to aid in the repair or replacement of your double glazed windows. There are many different methods to apply and certain areas will require a certain form of application or proof of eligibility, so it is best to check with your local authority prior to deciding how to proceed.
