How to Repair Double Glazed Windows

Many homes with double-glazed windows have issues like condensation, a decrease in the quality of insulation and windows that become difficult to open. These problems are typically a result of a fault with 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 a major issue that must be dealt with promptly. If a double- or triple-pane window is damaged the gas that seals it is unable to block cold air and warm air during winter is released. This means that your home is less well-insulated. Cracks can also get worse over time. Making them repairable now can prevent a more serious issue in the future.

The most important step to take when a crack appears is to determine what caused it. It's possible that a structural or impact problem caused the crack. In this case it's crucial to examine the rest of your windows for damage and determine the best course of action to take.

It is also a good idea to inspect the surrounding area of your home for any other issues which could be contributing to the crack. For instance windows that are located near to walls and doors and walls, the strain of expansion and contraction caused by temperature fluctuations could be causing the cracking.

Depending on the cause of the crack, there are a variety of ways to fix it. For example, if it was caused by an impact, you may be able to get away by replacing only the damaged pane of glass. In other cases, you may have to replace the entire window frame. This is a more complicated solution and requires the assistance of a professional.

If you've noticed 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 close the crack and stop further damage to your window.

Covering the crack with clear tape is another option. It's not the prettiest solution, but it does stop bugs and drafts from getting into your home. Glass repair film is an upgrade that can be applied quickly and provides a more sturdy level of protection. This is available from many double glazing companies and is well worth the investment to safeguard your windows.

Condensation Build-Up

Double glazing windows needing to be fixed are often because of condensation between the panes. This is because it typically indicates that the seal between the panes of windows has been breached which allows water vapour to get in. This can lead to condensation and other issues that could need the window replaced.

Double glazing is more effective at lessening condensation than single pane windows since it features a space between the glass that is either filled with air or a non-toxic gas. The space is then separated from the window frame by a spacer bar which acts as an insulation to stop heat loss. In many cases, the bar is filled with a silica gel, which is extremely effective in 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 reduce the amount of moisture that accumulates and allow it to evaporate. Utilizing upvc door repairs near me or opening the windows to create more air flow can help to remove moisture.

Another way to combat condensation is by installing a dehumidifier in your home. They are available for purchase at between PS60-PS150. They are a great investment that will not only decrease condensation, but also stop the growth of mould in your home, too.

Condensation can occur between the glass panes in your double glazing due to the outer air may be colder than the interior window pane. This causes the glass's surface to cool and create condensation. It can also happen when you change the temperature of your home, for instance by turning on or off the heating.

Condensation could also be a sign of poor double glazing, as older units were made with rubber strips, rather than the latest silicone type. They can become damaged over time. It may be possible to fix your seals, however this is only a temporary solution because the window will eventually fail in a different area.

Stained Glass

If you are having issues with a double-glazed window handle or lock, it is usually possible to fix it, rather than replace the entire glass pane. However, this is not necessarily a DIY job since special tools are required to ensure the repair is done in a way that does not compromise the seal or the purpose of the window.

The most common complaint of owners of double glazing is that their doors or windows have become difficult to open and close. This is typically caused by small warping in the frame or the hinges, but it could also be due to problems with the sealing. It could be that the issue is more than that and you should talk to an expert to discuss the possibilities.

Another frequent complaint is the forming of condensation between glass panes. This can be a sign that the seal is failing and is not able to hold in the gas that is insulating between the panes. Again, this is an easy fix and the gas that insulates can be restored with 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 with care to reveal the silver spacer bars. Cut these into pieces with a sharp knife. Keep your cut below the base of both the glass and the spacer bars. After you've separated the two pieces, place the top glass pane on the work surface. It is recommended to wear gloves during this step. Clean the glazed surface that faces the frame and the spacer frame. Be sure to remove any marks and smears, since these can affect the sealing of the window when it is put back together. Then, put the new spacer bar onto the glass pane and spread some adhesive around its edge to help it bond to the glass and silver spacer frame. Allow it to set before reassembling. It is recommended to have two people help you because it is difficult to align everything.

Gasket Seals

Although double glazing is extremely durable and designed to last for years to be, there are problems that can occur at times. It is crucial to address any issues immediately when they arise, whether it's draughts or problems with opening or closing.

Condensation between the two panes is one of the most frequent issues that owners of double-glazed windows report. It is usually due to an issue with the desiccant that absorbs moisture from the air in the insulated gap. If the desiccant is not working it can cause condensation to form within minutes and create a dark line on the window.

Another issue can arise when the gasket seal fails to keep 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 spot any indications of a leak in your double-glazed units, it is important to contact your installer as soon as possible.

Many companies offer a guarantee for their products. These warranties typically include a guarantee that is 10 or 20 years. Some companies offer lifetime assurances. It is essential to review the terms of your guarantee to find out what it covers and until the date it expires.


It might be worthwhile trying to resolve any hardware issues yourself before calling your double glazing provider to request repairs. For instance, you can try cooling or lubricating the mechanism to see whether it solves the issue. Alternatively, you can try taking the handle off or the window handle and cleaning it before returning it to its the correct position.

It is also essential to determine if your local council has insulation grants to help pay for the repair or replacement of double-glazed windows. There are numerous ways to apply, and some areas require a specific form of application or proof of eligibility, so it is always advisable to check with your local authority before deciding how to proceed.
