How to Repair Double Glazed Windows
Typically double glazing comes with a warranty of either 10 or 20 years. If your double-glazed windows show signs of aging, you might be eligible for them to be replaced under warranty.
Double-glazed window repair requires the re-sealing of your glass unit. The seal is not working if you see misting.
Glass that is damaged
A seal that is airtight is vital for double pane windows to function properly. The most common sign that a seal is failing is condensation forming between the glass plates. While condensation between glass is not an issue that is serious and can be fixed, it's typically an indication that the glass unit needs to be replaced. If you have an older double-glazed window, this could require replacing both the glass and the frame. If the frame is in good shape, you may be able to save money by just replacing the glass.
Glass is brittle and it's not unusual for double-pane windows that develop cracks over time. If the cracks aren't caused by mechanical damage, or an unusual impact on the window, they can be repaired with epoxy and elbow grease. Follow the instructions of the manufacturer and scrub the area of the crack using a wet cotton cloth. Then, apply epoxy to the crack. Let the epoxy completely dry before sanding and painting the repaired area.
A simple strip of masking tap can also be used to stop cracks from spreading. One strip of masking tape applied to each side of the crack should be sufficient to prevent superficial cracks from spreading, like stress-cracks that are caused by low temperatures. If you're dealing with deeper cracks that are already forming in your glass, it might be best to call an expert to ensure the safety of the repair.
It is risky and difficult to replace a single pane within double-paned windows. Double-pane windows are made as a complete unit, and sealed in the factory using inert gas, which means it's impossible to remove the glass without damaging the entire window. If you intend to replace the glass in your double-paned windows pick a manufacturer with an extensive warranty.
It's also a good idea to pad the window frame with newspaper before you attempt to remove the sash, and then replace any broken glass. This will help protect you from any sharp shards of glass that may fall on the way, and it'll also help to protect your home's trim or molding.
Condensation Build-Up
The good fact is that condensation between window panes is totally normal. It is caused by an imbalance in temperature and humidity of the air. The water vapour in air condenses when it comes into contact with cold, impenetrable surfaces like windows. Usually this is beneficial, especially in winter, as it prevents loss of heat.
If your windows appear like they are cloudy and have a thin layer of water on them, you must contact an experienced professional glazier. This indicates that the seal between the two panes is beginning to weaken, allowing moisture into the window.
You can stop this by using dehumidifiers, improving ventilation, or applying de-icing agents. There are companies that can remove excess moisture from double-glazed windows through drilling into the frame and injecting desiccant. This is a more involved procedure that requires the unit to be removed from the frame, and then opening each glass pane and thoroughly cleaning them, then filling them with desiccant and sealing them back up. This is typically a more expensive solution however, it's essential to check that the company you choose to work with is insured and is registered with FENSA.
Be aware that altering your double-glazed windows will end any warranties. If you have a warranty on your windows it is recommended to notify the manufacturer of any issues since they will be responsible for replacement units under warranty. It's best to consult an expert prior to undertaking any DIY repairs. This is particularly true for older units as they are often more susceptible to fail. It is best to replace the entire glazed panel in the event of this. You'll then have brand-new windows that will last for many years.
Scratches
Double-glazed windows aren't immune to scratches. This could be the result of environmental factors or can even be caused by the manner in which the window was initially installed.
Thankfully, many of these scratches are minor and can be easily fixed by a few do-it-yourself remedies. If your windows are scratched to the extent where you can feel them with your fingernail it is best to seek help from a professional so that the glass surface is restored to its original state.
These scratches occur by objects such as tree branches, pet nails and cleaning products which are abrasive rub against the glass of your windows. These scratches are usually removed by using non-abrasive products like iron oxide or polishes made of cerium dioxide. You'll need to use these until the scratch disappears.
Scratches can also result from sanding the wood trim on your windows. They can also occur during construction work. These scratches can be difficult for you to repair. However, a mixture of baking soda and water will aid in smoothing the surface after buffing and eliminate any remaining scratches.
Metal polish can be used to eliminate more severe scratches. Add a small amount of it to a cotton ball, or a clean microfibre towel, and gently rub the affected area in a circular motion. Be careful not to apply too much pressure since this could cause damage to the window. Once the area is smoothed, use a damp cloth to wash away any remaining polish.
Consider purchasing a non-abrasive special glass polish if you have a deep scratch you cannot seem to remove. This can be bought at any DIY store and should be applied following the instructions on the product packaging. Alternately, you can apply nail polish to smooth the area and cover any minor scratches on the glass of your window. Make sure that the nail polish is clean and is only applied to the scratched area of your window.
Haze
The presence of haze in the double-paned windows indicates that the seal between the two panes is broken. It is essential to get this repaired as soon as you can to ensure that you don't end up with moisture and dirt build-up between the panes. This could damage the glass and reduce its transparency.
There are a variety of options to remove the haze on your double paned windows. Use a defogging solution. This is a temporary solution. If you're looking for a long-lasting solution, seek out a professional glazing company that can repair the problem and replace the gaskets, if necessary.
Another way to solve the problem of haze in double-glazed windows is to drill tiny holes into the window frame, using a carbide-tipped drill. You can then insert desiccate packs into these holes, and then wash the window using rubbing alcohol. The water will help remove the haze off the window and clean it.
To avoid fogging, it's important to keep your windows clean and maintained by cleaning them frequently. This will allow you to look through the double panes and enjoy a stunning view from your home or garden. In addition, ensuring that your house is ventilated can also be beneficial.

Typically, insulated double-glazed windows are designed to last around 20 years. This is because they are designed to stand up to various weather conditions, such as extremely cold temperatures, extreme heat, humidity, and repeated closing and opening. However, it's crucial to keep in mind that the time-to-life of double-glazed windows may be reduced by poor installation or faulty materials.
