How to Repair Double Glazed Windows
Typically, double glazing comes with a guarantee of either 10 or 20 years. If your double-glazed windows are showing signs of ageing you could be eligible to have them repaired under warranty.
Double-glazed window repair requires replacing the seal on your existing glass. The seal isn’t working properly when you notice mist.
Damaged Glass
A seal that is airtight is crucial for double pane windows to function properly. The most frequent sign that a seal may be failing is the formation of condensation between the glass plates. Condensation between glass plates is not a major problem and can be corrected however it is an indication that your glass unit requires replacement. If you have an older double-glazed window, this may require replacing both the glass and the frame. If your frame is in good condition however, you could typically save money by replacing just the glazing.
Double-paned windows can develop cracks because of the fragility of glass. Unless the cracks are caused by mechanical damage or an unusual impact, it’s often possible to repair these cracks using epoxy and a small amount of elbow grease. Follow the manufacturer’s instructions and clean the cracked area using a wet cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to fully dry before applying paint and sanding to the repaired area.
A simple strip of masking tap can also be used to stop a crack from spreading. One strip of tape on both sides of the cracked area should be enough to keep superficial cracks, such as stress cracks caused by low temperatures, from escalating. If you notice more severe cracks in your glass that are already present, it’s best to contact an expert for repair.
It’s risky and difficult to replace a single pane in double-paned windows. Double-pane windows are constructed as a whole unit and sealed in the factory with inert gas, which means it’s impossible to remove the glass without damaging the entire window. If you’re planning to replace the glazing in your double-pane windows, be sure to choose a reputable brand with a long-lasting warranty.
It’s also a good idea to pad the window frame with newspaper before you attempt to remove the sash and replace any broken glass. This will shield your from any sharp shards that could fall on the way and also help to prevent any damage to your home’s trim or molding.
Condensation Build-Up
The good news is that condensation between window panes is totally normal. It’s caused by a disparity between the temperature of air and humidity levels that cause water vapour in the air to condense when it comes in contact with cold and impervious surfaces like windows. Usually this is an excellent thing, particularly during winter because it can help prevent heat loss.
However, if you’re noticing that your windows appear like they’re cloudy, with a film of moisture on them, it’s time to hire an expert Glazier. This is an indication that the air gap seal between two panes of glass is beginning to break down and allowing moisture into the window.
You can stop this by using a dehumidifier, improving ventilation or using a deicing agent. There are companies that will remove excess moisture from double-glazed windows through drilling into the frame and injecting desiccant. This requires removing the sealed unit from the frame and then cleaning each glass pane before refilling the desiccant. This will usually be an expensive option, but it’s worth checking that any company you use is fully insured and is registered with FENSA.
It is crucial to remember that tampering with your double-glazed windows isn’t advised and could end any guarantees. If you have windows that have a warranty It is recommended to inform the company of any problems as they will be responsible for the replacement of any defective units under warranty. Also, any damage incurred through tampering will likely not be covered under your warranty either, so it’s better to seek out expert advice prior to trying any DIY fixes. This is especially the case for older units because they’re more likely than modern ones to fail. It is recommended to replace the entire glazed panel in the event of this. Then you’ll have brand new windows that will last for many years.
Scratches
It’s not unusual for double glazed windows to be impacted by scratches to their surface. This can be a result of environmental conditions or even caused by the way in which the window was originally installed.
Fortunately, the majority of these scratches are superficial and can be easily fixed by a few do-it-yourself remedies. If you can feel the scratches on your windows using your fingernail, or if they are deep, it’s best to consult an expert to repair the glass to its original condition.
These scratches occur when objects like pet nails, tree branches and window repair cleaning products which are abrasive rub against the glass of your windows. These scratches are usually removed using non-abrasive materials such as iron oxide or polishes made from cerium dioxide. You will have to apply these products until the scratch disappears.
Scratches may also occur when you sand wood trim around your windows. They can also occur in the course of construction. These can be difficult to repair, but the use of baking soda and water should help smooth the surface and eliminate any scratches that remain.
For more severe scratches you can apply a polishing metal to smooth the area and remove scratches. Apply a small amount the product to a cotton ball or clean microfibre cloth and gently rub the affected area in a circular motion. Avoid applying too much pressure, because this could cause further damage to the window. Once the area is smooth, use a damp cloth to remove any remaining polish.
If you have a particularly deep scratch that you can’t get rid of, think about purchasing a non-abrasive glass polish. This can be bought at any DIY store and must be applied in accordance with the instructions on the product packaging. You can also use nail polish to cover up any superficial scratches on the window glass. Make sure you apply the nail polish only to the area that has been scratched.
Haze
The presence of haze in your double pane window is a sign that the airtight seal between the two glass panes has been damaged. It’s important to have the issue fixed as soon as you can to ensure that you don’t end up with moisture and dirt build-up between the panes. This can cause damage to the glass and cause a reduction in transparency.
There are many ways to fix the haze on double pane windows. One option is to apply a defogging spray. But, this is only an interim solution. If you’re looking for a long-lasting solution, you’ll need to get in touch with a professional glazing business who can fix the issue and replace the gaskets if necessary.
A carbide-tipped instrument can be used to make tiny holes into the window frame to remove the haze. Then, you can insert a desiccate bag into these holes, and then wash the window using rubbing alcohol. The water will help to remove the haze and cleanse the window.
To avoid fogging, it is essential to keep your windows clean and maintain them regularly. This will keep the double panes clean and allow you to enjoy a beautiful view of your garden or home. It is also important to ensure that your home is equipped with adequate ventilation. This will help to ensure that any condensation is swiftly eliminated, rather than being allowed to settle and then reseal the window.

This is because they are designed to stand up to various weather conditions, including very cold temperatures, high humidity, heat and frequent opening and closing. It is important to be aware that improper installation or faulty materials can decrease the life span of double-glazed windows.
