How to Repair Double Glazed Windows

Typically, double glazing comes with a warranty of either 10 or 20 years. So, if your double-glazed windows are showing signs of aging you could be eligible to have them repaired under warranty.

Double glazed window repair involves re-sealing your existing glass unit. The misting is a clear indication that the seal has failed and you have to repair it.

Glass damaged

A seal that is airtight is crucial for double pane windows to work correctly. The most common sign that a seal may be failing is condensation forming between the glass plates. While condensation between glass is not an issue that is serious and can be dealt with, it's typically a sign that the glazing unit is in need of replacement. If you have an older double glazed window, it could require replacing both the glass and the frame. If your frame is in good shape, you may be able to save money by just replacing the glass.

Glass is fragile and it's not unusual for double-pane windows to crack as time passes. If the cracks aren't caused by mechanical damage or a sudden impact on the window, they can be repaired with epoxy and some elbow grease. Begin by cleaning over the crack with a wet cotton rag. Then, apply epoxy to the crack following the manufacturer's instructions. Let the epoxy completely dry before sanding and painting the repaired area.

It's also possible to keep cracks from spreading by using an easy strip of masking tape. A single strip of masking tape applied to each side of the crack should suffice to stop superficial cracks from spreading, like stress-cracks caused by low temperatures. If you're dealing more serious cracks that have already developed in your glass, it might be better to contact an expert to ensure the safety of the repair.

It is dangerous and difficult to replace a single pane in double-paned windows. Double-paned windows are manufactured as a complete unit and sealed with inert gas in the factory. It is therefore impossible to take off just the glass without damaging the window. If you plan to replace the glass in your double-paned windows pick a manufacturer with a strong warranty.

It's also recommended to cover 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 that might fall during the process, and it'll also help to protect your home's trim or molding.

Condensation Build-Up

The good part is that condensation occurring between window panes is normal. It is caused by the difference in temperatures and humidity of the air. The water vapour in air condenses when it comes in contact with cold, inaccessible surfaces such as windows. Usually this is beneficial, especially in winter as it can help prevent heat loss.

If your windows appear like they are cloudy and have a thin layer of water on them, you must call a professional glazier. This is a sign that the seal between the two panes is beginning to break down, allowing moisture into the window.

You can stop this by making use of dehumidifiers, increasing ventilation, or using de-icing agents. There are also companies that will remove excess moisture from double-glazed windows through drilling into the unit and injecting desiccant. This requires removal of the sealed unit from the frame and then cleaning every glass pane before refilling the desiccant. This will usually be more expensive, however it's worth checking that any firm you choose to use is insured and is registered with FENSA.

It is important to keep in mind that altering your double-glazed windows is not recommended and could end any guarantees. If you have a guarantee on your windows it's always recommended to let the manufacturer know of any issues that arise since it is accountable for the replacement of units covered that are covered under warranty. Additionally, any damage that is caused by tampering is likely not be covered by your warranty either, therefore it's best to seek advice from a professional before making any DIY fixes. This is particularly the case for older units because they're more prone to fail. If this happens, it's best to replace the whole glazing panel. Then you'll have brand new windows that will last for years.

Scratches

Double-glazed windows are not impervious to scratches. This could be the result of environmental factors or could be caused by the way the window was originally installed.

Fortunately, the majority of these scratches are superficial and can be easily repaired by a few do-it-yourself remedies. If your windows are damaged to the point that you can feel the scratch with your finger, it is best to seek help from a professional to ensure that the glass surface is restored to its original form.

These scratches are caused by objects such as pet nails, tree branches and cleaning products which are abrasive rub against the glass of your windows. Usually, scratches can be eliminated using some non-abrasive solutions like iron oxide or cerium oxide polishes which you'll have to keep using until the scratch is gone.

Scratches can also be caused by sanding the wood trim around your windows. They can also occur during construction work. They can be difficult to repair, however the use of baking soda mixed with water can help smooth the buffed area and remove any scratches that remain.

Metal polish can be used to get rid of more severe scratches. Add a small amount to cotton balls or a clean microfibre towel and gently rub the area in a circular manner. Be careful not to apply too much pressure as this could exacerbate any further damage to the glass. Once the area is smooth, use a damp cloth to wash away any excess polish residue.

You may want to consider purchasing a non-abrasive glass polish if there is a an extremely deep scratch that you can't seem to remove. This is available at any DIY store and should be applied following the directions on the packaging. You can also use nail polish to smooth the area and cover any minor scratches that your window glass may have. Make sure that you only apply the nail polish to the area that has been scratched.

Haze

The presence of haze in your double glazing-paned window indicates that the seal between the two panes is broken. It is essential to get the issue fixed as soon as you can so that you don't end having dirt and moisture build-up between the panes. This could damage the glass and reduce its transparency.

There are a variety of options to remove the haze that has formed on your double paned windows. One option is to apply an anti-fogging spray. This is only a short-term solution. If you want a permanent solution, you must contact a professional glass business. They can fix the issue or replace gaskets if needed.

Another method to eliminate the problem of haze on double-glazed windows is to drill small holes into the frame of the window, using a carbide-tipped drill. You can then insert a desiccate packet into these holes and then wash the window with rubbing alcohol. The water will help clear the haze from the window and cleanse it.

To prevent fogging, it is essential to keep your windows clean and maintain them regularly. This will keep the double panes clean and allow you to take in the stunning view of your backyard or home. It is also important to ensure that your home has adequate ventilation.

In general, double-glazed windows that have insulation are designed to last around 20 years. They are designed to stand up to various weather conditions like extreme cold temperatures, heat and humidity as well as frequent openings and closings. But, it is crucial to keep in mind that the typical time-to-life of double-glazed windows may be reduced by poor installation or faulty materials.
