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 problems are typically a result of a problem with the hinges, mechanisms or handles.
You can fix these windows in a couple of easy steps.
Cracked Panes
If a double-pane window has damaged, it's a major issue that needs to be addressed quickly. When a double- or triple-pane window is damaged, the gas that insulates it is unable to block cold air and warm air during winter months escapes. This means that your home is less insulated. Cracks also worsen over time, so repairing them now prevents a potentially bigger problem in the future.
When a crack is discovered the most important thing is to determine the cause of it. The most common reason is a structural issue which can cause the break, but it's possible that the cause was an impact of some kind. In this situation, it is important to check your other windows for damage in order to determine the next steps.
You should also inspect the area around your home to determine whether there are any other issues that could be contributing. If your windows are located near walls or doors the stress resulting from temperature fluctuations may cause cracking.
Depending on the cause of the crack, there are various ways to repair it. For example, if it was caused by an impact, you may be able to work with replacing just the broken pane of glass. You may need to replace the entire window frame. This is a more involved solution and requires the help of an expert.
If you're facing a crack that didn't cause the frame move, it's generally easy to simply apply an adhesive between the fractured panes. This will repair the crack and stop further damage to your window.
Another option that's fairly simple is to cover the crack with clear tape. This isn't the best look, but it will stop bugs and drafts from getting into your home. Glass repair film is an upgrade that can be put in place quickly and provides a more solid level of protection. This is available from numerous double glazing companies and is worth the investment to protect your windows.
Condensation Build-Up
Double glazing windows that need to be repaired are usually because of condensation between the panes. It's usually a sign that a seal between two windows failed, allowing water to enter. upvc repairs can cause condensation, as well as other issues that may require the replacement of the window.
Double glazing can reduce condensation better than single panes of glass since it has a space between the two panes which is filled with non-toxic gases or air. The space between the glass and the window frame is separated by a spacer which acts as insulator. This helps to prevent loss of heat. In many instances the spacer bar has silica gel, which is efficient in preventing moisture from getting 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. Extraction fans and opening windows can help remove excess moisture.
Another way to stop condensation is by installing a dehumidifier inside your home. These units are priced between PS60 and PS150. They are an excellent investment that not only stops mould growth but also reduces condensation.
Condensation can occur between the glass panes in your double glazing because the outside air is warmer than the inside window pane. This causes the glass's surface to cool and create condensation. It can also happen in the event of an increase in temperature, like turning on the heating or cooling in your home.
In reality, condensation may be an indication of poor double glazing construction as some of the older units are made with rubber strips instead of the more modern silicone version that can degrade over time. It is possible to repair your seals, however this is only a temporary fix since 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 glass pane. However, this isn't always a do-it-yourself project as special tools are required to ensure the repair is done properly and will not affect the seal or the purpose of the window.
The majority of double glazing owners complain that their windows or doors are difficult to open. This is often caused by some slight warping of the frame or the hinges but can be caused by problems with the sealing. In some cases the issue could be more serious and it is advisable to talk to a professional about the options available.
Another frequent complaint is the development of condensation between the glass panes. This can be a sign that the seal is failing and is no longer holding in the insulating gas between the panes. It is also an easy fix. The gas insulating the panes can be replaced with a special adhesive to seal the gap between the panes.
Place the window that has been damaged on a flat surface. Peel back 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 spacer bars. Cut until you are able to cut the two pieces apart and when you've completed this place the top pane of glass onto your work surface (it is best to wear gloves while working). Clean the glazed surface that faces the frame as well as the spacer frame. Make sure to get rid of any marks and smears, because they can affect the sealing of the window when it is put back together. Finally, place the new spacer bar on the glass pane, and spread adhesive along its edges to help it bond to the glass and silver spacer frame. Let the adhesive dry before assembling. This is usually a task for two people as it can be tricky to arrange everything.
Gasket Seals
While double glazing is durable and designed to last for many years to come, there are still problems that can occur occasionally. From draughts to problems with closing or opening it is essential to address any problems promptly to prevent them from becoming worse.
One of the most common issues reported by double-glazed owners is condensation forming between the two panes of glass. It is usually due to an issue with the desiccant, which absorbs moisture from the air inside the insulated gap. Once the desiccant fails, condensation can form in minutes and leave a dark line on the window.
Another issue could arise if the gasket seal is not able to keep water and other pollutants from entering the insulated gap. This could lead to leaks around the edges of the frame and can also damage the surface of the double-glazed unit itself. Contact your installer immediately if you spot any indications that your double-glazed units leak.
A lot of companies offer a warranty for their products. These warranties usually include a period of guarantee of 10 or even 20 years. Some companies even provide lifetime assurances. Check the details of your warranty to find out what is covered and how long it will last.
It may be worth trying to solve any hardware problems yourself before calling your double glazing provider for repairs. For instance, you can try cooling or lubricating the mechanism to see whether that solves the issue. Alternately, you could try taking the handle off or the window handle and cleaning it prior to putting it back in place.
Contact your local council to find out whether they have grants available to assist you in the replacement or repair of your double-glazed windows. There are several ways to apply, and some areas may require evidence of eligibility or a particular type of application. It is worthwhile to check with your local authority to see what they require.
