14 Smart Ways To Spend Your Extra Money Repair Double Glazing Budget How to Repair Double Glazed Windows

Many properties with double-glazing experience issues like condensation, reduction in the insulation quality and windows that are difficult to open. These issues are usually a result of a defect in the hinges, mechanisms or handles.

Repairing these windows is possible by following a few simple steps.

Cracked Panes

If a double-pane window is damaged, it's an urgent issue that must be addressed immediately. When a double- or triple-pane window cracks, the gas that insulates it to keep out cold air and warm air during winter escapes. This means that your home is less insulated. Cracks can also become worse over time. Repairing them now will avoid a bigger problem in the future.

When a crack occurs the most important thing is to identify what caused it. The most commonly cited reason is a structural problem that can lead to the breakage, but it's also possible that the cause was an impact of a different kind. In this case it is crucial to check your other windows for damage to determine the next steps.

It is also an excellent idea to look over the area around your home for any other issues that 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.

Depending on what caused the crack, there are different solutions to fix the issue. For instance, if the crack was caused by an impact, you might be able to work by replacing only the damaged glass. Alternatively, you might need to replace the entire window frame. This is a more complex solution, and it requires the assistance of an expert.

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

Another option that's fairly simple is to cover the crack with clear tape. It's not the most appealing solution, but it does stop bugs and drafts from getting into your home. A step up from that is a glass repair film that's designed to be quickly applied and offers more durable protection. This is available from numerous double glazing companies and is worth the investment to safeguard your windows.

Condensation Build-Up

Condensation build-up in between the panes of double-glazing is one of the most common reasons why people need to repair their windows. It's usually a sign that the seal between two windows has failed, allowing water get in. This water vapour can cause condensation and other issues that may require the window to be replaced.

Double glazing is more effective at reducing condensation than single panes of glass due to the fact that it has a space between the two panes which is either filled up with air or non-toxic gases. The space between the glass and the window frame is separated by a spacer which acts as an insulation. This prevents loss of heat. In many instances the spacer 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 regularly wipe down and clean your windows. This will reduce the amount of moisture that is accumulated and allow it to evaporate. Opening windows and using extraction fans can help remove excess moisture.

Installing a dehumidifier is a different option to prevent condensation. They can be purchased for between PS60 and PS150. They are a good investment that will not only decrease condensation, but also prevent the growth of mould within your home, too.

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

Condensation can also be an indication of poor double-glazing, since older units were made with rubber strips, not the latest silicone type. These can deteriorate over time. In certain cases it is possible to have your seals replaced however it's worth noting that this is only the short-term solution as the window will eventually fail in a different area, which means you'll need to replace it anyway.

Stained Glass

It is possible to repair the double-glazed window handle or locking mechanism rather than replace the entire glass pane. This isn't an easy DIY task, as you will need special tools to ensure that the repair is completed right.

Most homeowners with double glazing complain that their doors or windows are difficult to open. upvc repair is typically caused by some slight warping of the frame or the hinges, but it could also be due to problems with the sealing. In some instances, the issue may be more serious and it is worth speaking to a professional regarding the possibilities available.

Another common complaint is the forming of condensation between glass panes. This could be an indication of a failing seal that isn't holding the insulating gases between the glass 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.

Place the window that has been damaged on an even surface. Peel off the black sealant carefully to reveal the silver spacer bars. Cut these into pieces with a sharp knife. Keep your cut just below the bottom of both the glass and the silver spacer bars. After you've separated the two pieces, place the top glass pane on the work surface. It is recommended to use gloves for this step. Once again thoroughly clean both the glazed side that is facing into the frame and the spacer frame taking care to remove any marks or smears since they can affect the seal when the window is put back together. Then, put the new spacer bar on the glass pane and apply adhesive on its edges to aid in bonding it to the glass and silver spacer frame. Allow it to set before reassembling. This is usually a job for two since it can be tricky to align everything.

Gasket Seals

While double glazing is highly durable and designed to last for years to come, there are still issues that can arise from time to time. From draughts, to problems in closing or opening, it is important to have any faults fixed quickly to prevent them from getting worse.

Condensation between the two panes is among the most common issues double-glazed owners have to deal with. This is caused by the failure of the desiccant which absorbs moisture from the air within the gaps that are insulated. Once the desiccant fails, condensation can form in minutes and leave a dark mark on the window.

Another problem that can occur is when the gasket seal fails to keep water and other pollutants out of the insulated gap. This can lead to leaks at the edges of the frame and also damage 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 warranty on their products and these often include a guarantee of either 10 or 20 years, with some even offer lifetime guarantees. It is important to check the details of your guarantee to determine what it covers and until when it expires.

You might want to try and resolve any hardware problems yourself before making contact with a double glazing company. For instance, you can try cooling or lubricating the mechanism to determine whether it solves the issue. Alternately, you could try taking the handle off or the window handle and cleaning it before placing it back in the correct position.

Check with your local council to determine whether they have grants available to aid in the replacement or repair of your double-glazed windows. There are a variety of ways to apply, and some areas will require a particular form of application or proof of eligibility, therefore it is best to check with your local authority before deciding on how to proceed.
