How to Repair Double Glazed Windows

Many homes with double glazing experience problems such as condensation, a decrease in the quality of insulation and windows that become difficult to open. These problems are typically a result of a defect in the hinges, mechanisms, or handles.

It is possible to fix these windows by following a few simple steps.

Cracked Panes

A double-paned windows that are cracked is a serious issue that must be addressed immediately. When a double- or triple-pane windows cracks the gas that seals it is unable to block 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 near future.

If a crack develops, the most important thing 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 it was caused by an impact of some sort. In this case it's crucial to examine the rest of your windows for damage and determine the best course of action to take.


You should also inspect the surrounding area to determine if there are any other issues that could be contributing. If your windows are located near other doors or walls, the stress caused by temperatures can cause cracking.

There are several ways to fix a crack dependent on the reason. If the crack was caused by an impact, you may be able to replace the damaged glass. It is possible to replace the whole window frame. This is a more complicated procedure, and requires the assistance of an expert.

However, if you're dealing with a crack that didn't cause the frame to move, it's usually easy to simply apply an adhesive between the fractured panes. This will repair the crack and preserves your window from any further issues and is certainly worth a try in this instance.

Another option that is fairly easy is to cover the crack with clear tape. This doesn't offer the best look, but it will prevent drafts and bugs from entering your home. The next step is the glass repair film which is made to be easily applied and provides more robust protection. Many double glazing companies provide this service, which is worth the investment in order to protect your windows.

Condensation Build-Up

Double glazing windows that need to be repaired are usually because of condensation between the panes. This is because it typically indicates that the seal between the window panes has failed which allows water vapour to get in. This moisture can then create condensation and other issues that could need the window replaced.

Double glazing reduces condensation better than single panes of glass since it has a space in between the two panes which is filled 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 helps to prevent heat loss. In many instances the spacer bar has silica gel which is effective in preventing moisture from entering between the glass panes.

It is therefore crucial to regularly wipe down and clean your windows. This will decrease the amount of moisture that builds up and let it evaporate. Opening windows and using extraction fans can help eliminate excess moisture.

Installing a dehumidifier can be another option to prevent condensation. They are available for between PS60 and PS150. They are an excellent investment that not only stops mould growth, but also helps to reduce condensation.

Condensation can happen between the glass panes of your double glazing as the air outside may be cooler than the interior pane. This causes the glass's surface to cool and create condensation. It could also occur when you alter the temperature of your home, for example by turning off or on the heating.

Condensation is also an indication of poor double glazing as older units were made with rubber strips, rather than the latest silicone type. They are susceptible to deterioration with time. It is possible to fix your seals, but this is only a temporary fix because the window will eventually fail in a different location.

Stained Glass

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

Most homeowners who have double glazing complain that their windows or doors are difficult to open. This is often caused by a slight warping of the frame or the hinges, but it could be caused by problems with the sealing. In certain cases, the issue could be more severe than this and it is worth speaking with a professional about the options available.

Another frequent complaint is the development of condensation between the glass panes. This could be an indication of a failing seal that isn't retaining the insulating gases between the glass panes. It is also an easy fix and the insulating gases can be reinstated with an adhesive that is specifically designed to close the gap between the panes.

Place the damaged window on an even surface. Peel back the black sealant, revealing the silver spacer bar and cut it with a sharp blade, being sure to stay under the base of the glass and silver spacer bar. Cut until you are able to split the two pieces, and after you've done this, place the top piece of glass on your work surface (it is best to wear gloves while working). Clean  Repair My Windows And Doors  glazed surface that faces the frame, as well as the spacer frame. Make sure to get rid of any marks or smears as they could impact the seal of the window when it is reassembled. Lastly, position the new spacer bar onto the glass pane, and spread adhesive on its edges to help it bond to the glass and silver spacer frame. Let it set before reassembling. This is typically a task for two as it can be tricky to align everything.

Gasket Seals

Although double glazing is extremely durable and is designed to last for years to be, there are issues that can arise occasionally. From draughts to problems in closing or opening it is essential to have any faults fixed as soon as possible to prevent them from becoming worse.

Condensation between the two panes is among the most common issues owners of double-glazed windows report. This is due to the failure of the desiccant that absorbs moisture in the air within the space that is insulated. Once the desiccant fails, condensation can form in minutes and leave a dark line on the window.

Another issue can arise when the gasket seal fails to prevent water and other contaminants from entering the gap. This could cause leaks around the edges of the frame and also damage the surface. If you observe any indications of a leak in your double glazed units, it is crucial to notify your installer as soon as possible.

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

It may be worth trying to solve any hardware issues yourself prior to contact your double glazing company for repairs. For instance, you could, try cooling or lubricating the mechanism to determine whether that solves the issue. You can also try cleaning the handle or window handle prior to reinstalling it.

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