How to Repair Double Glazed Windows
Many properties with double glazing are plagued by problems like condensation, a decline in the quality of insulation and windows that are difficult to open. These issues are usually caused by an issue with the hinges or handles.
Repairing these windows is possible by following a few simple steps.
Cracked Panes
If a double-pane window has damaged, it's an urgent issue that must be addressed immediately. Triple- and double-pane windows are insulated by gases that ensure warm air is kept in during winter and cold air out. So, when one of these panes breaks the gas escapes and your home is less insulated. Cracks also worsen over time, so repairing them now prevents a potentially larger issue in the future.
When a crack is discovered the most important step is to determine what caused it. The most commonly cited cause is a structural issue that could cause break, but it's possible that it was caused by an impact of some kind. In this situation it is imperative to inspect your other windows for damage in order to determine the next steps.
It's also an excellent idea to look over the area around your home for any other problems which could be contributing to the crack. If your windows are near walls or doors the stress caused by temperatures can be causing cracks.
There are several ways to repair a crack depending on the cause. If the crack was caused by a blow, you may be able to replace only the broken glass. Or, upvc window repairs may need to replace the entire frame of your window. This is a more complex solution that requires the assistance of a professional.
However, if you're dealing with a fracture that didn't cause the frame to move, it's generally simple to apply an adhesive between the broken panes. This fixes the fracture and protects your window from future problems It's definitely worth trying in this situation.
Another option that is fairly easy is to cover the crack with clear tape. It's not the most attractive solution, but it does stop drafts and bugs getting into your home. A step up from that is the glass repair film which is designed to be applied quickly and offers greater protection. Many double glazing companies provide this service, which is worth the cost to safeguard your windows.
Condensation Build-Up
Condensation that builds up between the panes of double-glazing is one of the most frequent reasons people have to fix their windows. This is because it usually indicates that the seal between the two panes of windows has been breached which allows water vapour to get in. This moisture can then create condensation and other issues that may require the window to be replaced.
Double glazing is superior at lessening condensation than single pane windows because it has a space between the glass which is filled with air or gas that is non-toxic. The space is then separated from the window frame by a spacer bar, which acts as an insulator to help keep heat from escaping. In many cases the spacer bar is made up of silica gel that is effective in preventing moisture from getting between the glass panes.
It is therefore crucial to clean and regularly clean your windows. This will reduce the amount of moisture that builds up and allow it to evaporate. Opening the windows to allow for more air flow can help to remove moisture.
Another way to combat condensation is to install a dehumidifier inside your home. These units are available for purchase at between PS60-PS150. They are a good investment that will not only reduce condensation but prevent mould growth within your home, too.
Condensation between the glass panes of your double glazing could occur because the outer air is colder than that of the inner window pane, causing the surface to cool and form condensation. It could occur when you alter the temperature of your home, such as by turning on or off the heating.
In reality, condensation may be a sign of poor double glazing construction because some older models are constructed with rubber strips instead of the more modern silicone type that can degrade over time. In certain cases it's possible to have your seals replaced but it's important to remember that this will only offer an immediate solution since the window will eventually degrade in a different area, which means you'll have to replace it eventually.
Stained Glass
It is possible to repair the double-glazed window handle or locking mechanism rather than replace the entire pane of glass. However, this isn't always a DIY project since specific tools are required to ensure the repair is done correctly and does not compromise the seal or the function of the window.
The most frequent complaint from double glazing owners is that their windows or doors are becoming difficult to open and close. This can be due to some slight warping of the frame or hinges but it can also be a problem with the seal. In some cases the issue may be more serious than this and it is worth speaking to a professional about the options available.
Condensation between the glass panes is a common complaint. This could be a sign that the seal is failing and is no longer holding in the insulating gas between the panes. Again, this is an easy fix. The gas that insulates can be restored with a special adhesive to seal the gap between the panes.
Begin by placing the damaged window on a flat work surface. Carefully peel back the black sealant, revealing the silver spacer bar and cut into this with a sharp blade, making sure to stay below the base of the glass and silver spacer bar. Cut until you are able to separate the two pieces and when you've completed this place the top pane of glass onto your work surface (it is recommended to wear gloves while working). Clean the glazed surface that faces the frame and the spacer frame. Be sure to remove any marks and smears, as they could affect the seal of the window when it is put back together. Lastly, position the new bar onto the glass pane and apply adhesive around its edge to aid in bonding it to the glass and the silver spacer frame. Let the adhesive dry before reassembling. This is usually a job for two people as it can be difficult to arrange everything.
Gasket Seals
Double glazing is designed to last many years however, there are certain issues that could arise. It is essential to fix any problems as soon as they occur, whether it's draughts or problems with opening and closing.
Condensation between the two panes is one the most common problems that double-glazed owners report. This is caused by the failure of the desiccant which absorbs moisture from the air within the gaps that are insulated. If the desiccant is not working the condensation will 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 pollutants from entering the gap. This can cause leaks at the edges of the frame, and also damage the surface. If you spot any indications of leaks in your double-glazed units, it is important to contact your installer as soon as possible.
Many companies will provide a warranty for their products. These usually include a guarantee period of either 10 or 20 years, with some even offer lifetime assurances. It is essential to review the specifics of your guarantee to determine what it covers and until the date it expires.
It is possible to try to solve any hardware problems yourself prior to contacting your double glazing supplier to request repairs. For instance, you can, try cooling or lubricating the mechanism to see if that fixes the problem. Alternatively, you can try removing the handle or window handle and then cleaning it before returning it to its place.
It is also important to determine if your local council has insulation grants to aid in the replacement or repair of your double-glazed windows. There are a variety of ways to apply, and some areas may require evidence of eligibility or a specific form of application. It is worth checking with your local authority to find out what they require.
