The Ultimate Glossary Of Terms About Repair Double Glazing How to Repair Double Glazed Windows

Many properties with double-glazing experience issues with condensation, a reduction in the insulation quality and windows that are difficult to open. upvc window repairs are typically 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

A double-paned window that is damaged is a serious problem that needs to be addressed immediately. When a double- or triple-pane window is damaged the gas that seals it will keep out cold air and warm air during winter escapes. This means that your home is less insulated. Cracks can get worse as time passes. Repairing them now will prevent a larger problem in the future.

The most important step to take when you notice a crack is to determine what caused it. The most commonly cited reason is a structural problem that can lead to the break, but it's possible that there was an impact of a different kind. In this case it's crucial to examine the rest of your windows for damage and determine the next steps to take to fix the issue.

It's also a good idea to inspect the area around your home for any other issues which could be contributing to the crack. If your windows are located near other doors or walls the stress caused by temperature fluctuations may cause cracking.

There are many ways to repair a crack dependent on the reason. If the crack was caused by an injury, you might be able replace just the damaged glass. In other cases, you may have to replace the entire frame of your window. This is a more involved solution, and it requires the help of a professional.

If you're dealing with a fracture that did not cause the frame to move, it's generally easy to simply apply an adhesive between the broken panes. This will close the crack and prevent further damage to your window.

Covering the crack with clear tape is a different option. It's not the most attractive solution, but it will stop bugs and drafts from entering your home. Glass repair film is an upgrade that can be put in place quickly and offers a more solid level of protection. This is available from numerous double glazing companies and is well worth the investment to safeguard your windows.

Condensation Build-Up

Condensation build-up in between the two panes of double glazing is one of the most frequent reasons people have to fix their windows. It's usually a sign that the seal between two windows was not strong enough, allowing water to get in. This can lead to condensation and other issues that could require the window to be replaced.

Double glazing is much better at reducing condensation than single pane windows since it features a space between the glass which is filled with air or a non-toxic gas. The space between the glass and the window frame is separated by a spacer, which acts as an insulation. This helps prevent heat loss. In a lot of cases, the bar is filled with a silica gel, which is extremely effective at picking up moisture and preventing it from getting between the glass panes.

This is the reason it is important to clean your windows frequently and keep them clean since this will reduce the amount of condensation that accumulates and allows it to evaporate. Utilizing extractor fans or opening the windows to allow for more air flow can also help remove excess moisture.

Another method to fight condensation is by installing a dehumidifier inside your home. These units can be purchased for around PS60-PS150 and are a great investment that will not only reduce condensation, but also prevent the growth of mould in your home as well.

Condensation between the glass panes of your double-glazing could occur because the air outside is colder than the inside window pane, causing the surface to cool down and form condensation. It can also happen when you change the temperature of your home, for instance by switching off or turning on the heating.

In reality, condensation may be an indication of a poor double glazing design because some older models are constructed with rubber strips instead of the more modern silicone type which may degrade over time. It may be possible to repair your seals, however this is only a temporary fix because the window will eventually fail in a different area.

Stained Glass

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

The most common complaint of owners of double glazing is that their windows or doors are becoming difficult to open and close. This is usually due to some slight warping of the frame or the hinges, but it could also be due to issues with the sealing. It could be that the issue is more serious and you should speak to an expert to discuss your options.

Condensation between glass panes is a different complaint. This could indicate that the seal is failing and is not able to hold the insulating gas between the panes. Again, this is an easy fix and the gas that insulates can be restored by using an adhesive that is specifically designed to close the gap between the panes.

Start by placing the broken window on a flat work surface. Peel back the black sealant gently to reveal the silver spacer bars. Cut into these with a sharp knife, staying below the base of both the glass and the silver spacer bars. After you have separated the two pieces, place the top glass pane on your work surface. It is best to use gloves for this step. Clean both the glazed side that is facing into the frame and the spacer frame taking particular care to remove any marks or smears as they could affect the seal when the window is put back together. Then, put the new spacer bar onto the glass pane, and spread adhesive on its edges to ensure it bonds with the glass and the silver spacer frame. Let the adhesive dry before assembling. It is recommended that two people do this job because it is difficult to align everything.

Gasket Seals


Double glazing is designed to last many years however, there are certain issues that could arise. From draughts to issues with closing or opening, it is important to fix any issues promptly to avoid them becoming worse.

One of the most common problems reported by double glazed owners is condensation that forms between the two panes of glass. It is usually due to an issue with the desiccant, which absorbs moisture from the air within the gaps that are insulated. Once the desiccant fails it can cause condensation to form within minutes and leave a dark mark on the window.

Another issue can arise when the gasket seal fails to stop water and other contaminants from leaking into the insulated gap. This can cause leaks around the edges of the frame and could also cause damage to the surface of the double glazed unit itself. If you notice any signs of a leak in your double glazed units, it is important to contact your installer as quickly as you can.

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

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

Check with your local council to find out whether they have any grants to assist you in the replacement or repair of your double-glazed windows. There are a variety of ways to apply, and some areas may require the proof of eligibility or a particular type of application. It is worthwhile to check with your local authority to determine what they need to know.
