How to Repair Double Glazed Windows
Double glazing is typically covered by a guarantee of 10 or 20 year. 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 re-sealing your existing glass unit. The seal is not working if you see misting.
Glass damaged
Double pane windows rely on an airtight seal to work correctly. The most typical indication that a seal is not working is when condensation forms between the glass plates. While condensation between glass is not an issue that is serious and can be dealt with, it's typically an indication that the glazing unit requires replacement. If you have an older double glazed window, this could mean replacing both the glass and the frame. If your frame is in good condition however, you could typically save money by replacing only the glazing.
Glass is fragile and it's not unusual for double-pane windows to develop cracks as time passes. Unless the cracks are caused by mechanical damage or a sudden impact, it's usually possible to repair these cracks using epoxy and tiny amount of elbow grease. Follow the manufacturer's instructions and scrub the area of the crack by using a damp cotton cloth. Then, apply epoxy to the crack. Allow the epoxy to fully dry before sanding and painting over the repaired area.
It's also possible to prevent a crack from spreading with an easy strip of masking tape. One strip of tape placed on both sides of the crack area is enough to stop superficial cracks, such as stress cracks that are caused by low temperatures, from getting worse. If you're dealing with deeper cracks that are already forming in your glass, it could be better to contact a professional to ensure the safety of the repair.
The process of replacing one pane of double-pane window glass is a dangerous and challenging DIY job. Double-paned windows are manufactured as a unit and sealed with inert gas in the factory. Therefore, it is impossible to remove just the glass without damaging the window. If you're planning to replace glazing in your double-pane windows, make sure you select a high-quality brand that is backed by a solid 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 your from any sharp shards that might fall during the process, and it'll also help to prevent any damage to the trim of your home or molding.
Condensation Build-Up
The good news is that condensation between window panes is normal. It's due to a gap between the temperature of the air and humidity levels that cause water vapour to condense upon contact with cold impenetrable surfaces such as windows. This is usually a great thing in winter, as it prevents loss of heat.
If you notice that your windows are appearing 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 glass panes is beginning to break down and allowing moisture into the window.
You can stop this by using dehumidifiers, improving ventilation, or by applying de-icing agents. There are also specialists who can fix condensation build-up in double glazed windows by drilling holes into the window and pumping or injecting a specific desiccant to eliminate the excess moisture. This is a more complex procedure that requires the sealed unit to be removed from the frame, allowing access to each glass pane to clean them thoroughly, then filling them with desiccant and sealing up again. This is usually an expensive option, but it is worth checking whether the company you select is insured and is registered with FENSA.
It is important to keep in mind that tampering with your double glazed windows is not advised and will invalidate any guarantees. If you have a guarantee on your windows, it's recommended to let the company be aware of any issues that arise, as it is accountable for the replacement of units covered under warranty. It is best to consult an expert prior to undertaking any DIY repairs. This is particularly relevant for older units since they are sometimes more prone to fail. It is recommended to replace the entire glass panel if this happens. This way, you'll have brand-new windows that will last for many years to come.
Scratches
It is not uncommon for double glazed windows to be impacted by scratches on their surfaces. This can be due to environmental factors, or even the manner in which the window was constructed.
Most scratches are superficial, and can be easily fixed with some home remedies. If your windows are damaged to the point where you can feel them with your fingernail, it is best to seek help from a professional to ensure that the glass is restored to its original form.
These scratches are caused by objects like pet nails, tree branches and cleaning products that are abrasive scrape against the glass of your windows. Usually, scratches can be removed with some non-abrasive solutions like iron oxide or cerium oxide polishes which you'll need to continue using until the scratch is gone.
Scratches can also be caused by sanding wood trim around your windows and may occur during construction work. These scratches can be difficult for you to fix. However, a mixture of baking soda and water will help smooth out the surface that has been buffed and remove any remaining scratches.
Metal polish can be used to get rid of more severe scratches. Apply a small amount the product to a microfibre or cotton cloth and gently rub the affected area in an upward motion. Be careful not to apply too much pressure as this could exacerbate any further damage to the glass. After the area has been smoothed using a damp cloth to clean any polish residue that remains.
Think about purchasing a non-abrasive glass polish if you've got a a deep scratch you cannot remove. This is available at any DIY store and must be applied according to the instructions on the product packaging. You can also use nail polish to cover any scratches on the glass of your window. Make sure that you only apply the nail polish only to the area scratched.
Haze
The presence of haze in the double-paned windows indicates that the seal between the two panes is damaged. This must be fixed as soon as possible so that dirt and moisture do not build up between the glass panes. This can damage the glass and reduce its transparency.
There are several ways to fix the haze on double pane windows. One option is to apply a defogging spray. This is only a short-term solution. If you're looking for a permanent solution, you'll need to get in touch with a professional glazing business that can fix the issue and replace the gaskets if necessary.
A carbide-tipped instrument can be used to drill small holes in the window frame to remove the haze. You can then tuck the desiccate packet inside these holes and wash the window with rubbing alcohol. The water will help to remove the haze from the window and cleanse it.
It is essential to ensure that your windows are maintained and regularly cleaned to prevent fogging. This will keep your double panes clear and allow you to take in the stunning view of your home or garden. Additionally, making sure that your home is ventilated is also beneficial. This will ensure that any condensation is swiftly removed, instead of being allowed to settle and reseal the window.
It is not enough to clean and maintain your windows regularly, but also ensure that they are properly installed. Installing your windows should only be completed by a glazing company with expertise. This will ensure that the gaskets and seals are installed properly, and fit tightly. It is also a good idea to have your windows repaired as soon as you can, before they begin to exhibit signs of wear and tear. This will save you from expensive double pane window repair s.

This is because they are designed to withstand all kinds of conditions like extremely cold temperatures, high heat, humidity as well as repeated opening and closing. It is important to remember that the time-to-life of double-glazed windows can be diminished by poor installation or faulty materials.
