This Most Common Repair Double Glazing Debate It's Not As Black And White As You Think
How to Repair Double Glazed Windows

Many properties with double glazing have issues like condensation, a drop in insulation and windows that are difficult to open. These issues are usually the result of a fault with the hinges, mechanisms or handles.

You can fix these windows in a couple of easy steps.

Cracked Panes

If a double-pane window is damaged, it's a major issue that needs to be dealt with promptly. Triple- and double-pane windows are insulated with gases that ensure warm air is kept in during winter and cold air out, so when one of these panes breaks the gas escapes and your home becomes less well-insulated. Cracks can get worse with time, so fixing them now prevents a potentially more serious issue in the future.

When a crack occurs, the most important thing is to identify what caused it. The most frequent reason is a structural problem that can lead to the breakage, but it's also possible that it was caused by an impact of some sort. In this situation it's imperative to inspect the rest of your windows for damage and determine the next steps to take.

It is also an excellent idea to look over the surrounding area of your home for any other problems that could be causing the crack. If your windows are located near walls or doors the stress caused by changes in temperature could be causing cracking.

Depending on the reason for the crack, there are various ways to fix it. If the crack was caused by a blow, you may be able to replace the damaged glass. You may need to replace the entire window frame. This is a more complicated solution and requires the assistance of a professional.

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

Covering the crack using clear tape is an alternative option. It's not the most appealing solution, but it prevents bugs and drafts from getting into your home. A step up from that is a glass repair film designed to be quickly applied and offers more durable protection. This is available from many double glazing companies and is well worth the investment to secure your windows.

Condensation Build-Up

Double glazing windows that need to be repaired are usually due to condensation between the panes. It is usually a sign that the 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 can reduce condensation better than single panes of glass since it has a space in 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 an insulation. This prevents loss of heat. In many cases the spacer bar has silica gel, which is efficient in preventing moisture from entering between the glass panes.

This is why it's essential to clean your windows frequently and keep them clean as this will minimise the amount of condensation that accumulates and allow it to evaporate. Utilizing extractor fans or opening the windows to create more airflow can also help to remove moisture.

Installing a dehumidifier is a different option to prevent condensation. These units are priced between PS60 and PS150. They are a fantastic investment that will not only stop mould growth but also reduces condensation.


Condensation between the glass panes of your double glazing could occur because the outer air is colder than that of the inner window pane, which causes the surface to cool down and form condensation. It could also happen when you change the temperature in your home, for instance by turning on or off the heating.

Condensation is also a sign of poor double glazing because older models were constructed with rubber strips instead of the modern silicone variety. They are susceptible to deterioration with time. In certain cases it's possible to have your seals repaired however it's important to note that this will only be a short term solution as the window will eventually break down in another area, meaning you'll need to replace it eventually.

Stained Glass

If you're having trouble with a double-glazed window handle or lock, it is often possible to repair it instead of having to replace the entire glass pane. This isn't an easy DIY project, since you'll need specialized tools to ensure that the repair is carried out properly.

The most common complaint of homeowners of double glazing is that their doors or windows are becoming difficult to open and close. This can be due to some slight warping of the frame or hinges but it could also be due to issues with the seal. In some cases the issue could be more serious than this and it is advisable to talk with a professional about the possibilities available.

Another issue that is frequently reported is the formation of condensation between glass panes. This could be a sign that the seal is failing and not able to hold the gas that insulates between the panes. This is an easy fix. The insulating gas can be restored by using special glue to fill the gap.

Place the damaged window on an even surface. Peel back the black sealant gently to reveal the silver spacer bars. Cut these into pieces with a sharp knife, staying below the base of both the glass and the spacer bars. Cut until you can separate the two pieces and after you've done this, place the top piece of glass onto your work surface (it is best to wear gloves here). Clean the glazed side that faces the frame and the spacer frame. Make sure to get rid of any smears or marks, because they can impact the seal of the window when it is rebuilt. Lastly, position the new bar onto the glass pane, and spread adhesive around its edge to help it bond to the glass and silver spacer frame. Allow the adhesive to dry before assembling. It is recommended to have two people do this job as it can be difficult to get everything aligned.

Gasket Seals

While double glazing is durable and is designed to last for a long time to come, there are still problems that can occur at times. It is essential to fix any faults immediately when they arise, whether it's draughts or problems with opening or closing.

Condensation between the two panes is one of the most common problems that double-glazed owners report. It is usually due to a failure of the desiccant that absorbs moisture from the air inside the insulated gap. Once the desiccant has failed, condensation can develop in minutes and cause an ugly line across the windows.

Another issue that could arise is when the gasket seal fails to keep water and other contaminants from the gap between the insulated gaps. This can cause leaks at the edges of the frame, and also damage the surface. If you notice any signs of leaks in your double glazed units it is crucial to notify your installer as quickly as you can.

A lot of companies offer a warranty for their products. These warranties typically include a guarantee of 10 or even 20 years. Some companies even provide lifetime guarantees. Examine the specifics of your warranty to determine what is covered and how long it will last.

You may want to try and resolve any hardware problems yourself before making contact with a double glazing company. For upvc window repairs near me , you can, try cooling or fluidizing the mechanism to see whether that solves the issue. You can also try cleaning the handle or window handle before reinstalling it.

It is also crucial to check whether your local council has any insulation grants available to aid in the replacement or repair of double-glazed windows. There are numerous methods to apply and certain areas will require a certain form of application or proof of eligibility, therefore it is always worth checking with your local authority prior to deciding on how to proceed.
