How to Repair Double Glazed Windows
Typically double glazing comes with a warranty of 10 or 20 years. If your double-glazed windows begin to show signs of aging, you may be entitled for them to be repaired under warranty.
Double-glazed window repairs require resealing the existing glass unit. Misting is a clear sign that the seal is broken and you will need to get it repaired.
Damaged Glass
Double pane windows require an airtight seal in order to work properly. The condensation between the glass plates is a typical sign of a faulty seal. While condensation between glass isn't a serious problem and can be fixed, it's typically an indication that the glazing unit needs to be replaced. If you have an older double glazed window, this may require replacing both the frame and the glass. If the frame is in good shape however, you could typically save money by replacing just the glass.
Double-paned windows can crack because of the fragility of glass. If the cracks were not caused by mechanical damage or a sudden impact on the window they can be fixed with epoxy and some elbow grease. Follow the directions of the manufacturer and clean the cracked area by using a damp cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to completely dry before sanding down and painting over the repaired area.
It's also possible to keep cracks from spreading with an easy strip of masking tape. One strip of tape on both sides of the damaged area is enough to keep superficial cracks, such as stress cracks that are caused by low temperatures, from worsening. If you notice more severe cracks in your glass that are already present, it's recommended to speak with an expert to repair the damage.
Attempting to replace just one pane of double-pane glass is a risky and difficult DIY task. Double-paned windows are constructed as a unit and sealed with inert gases in the factory. Therefore, it is impossible to remove just the glass without damaging the window. If you're planning to replace glass in your double-pane windows, make sure you use a quality brand that comes with a solid warranty.
You can also use newspaper to protect the window frame prior to deciding to remove the sash or replace any broken glass. This will shield you from any sharp glass shards which might fall during the process. It also protects against any damage to the molding or trim of your home.
Condensation Build-Up
The good fact is that condensation between window panes is normal. It's caused by a disparity between the temperature of air and humidity levels and causes water vapour in the air to condense when it comes in contact with cold and impervious surfaces like windows. This is usually a great thing during winter, since it stops heat loss.
If your windows appear cloudy and have a film of water on them, you must contact a professional glazier. This is a sign that the 'air gap' seal between the two panes of glass has begun to weaken and is letting moisture into the window.
You can stop this by using dehumidifiers, enhancing ventilation, or applying de-icing agents. Additionally, there are specialist companies who will repair condensation build-up in double glazed windows by drilling holes in the window and then injecting or pumping a special desiccant to remove the excess moisture. This involves taking the sealed unit out of the frame and then cleaning each glass pane before refilling the desiccant. This is typically an expensive option, but it's worth checking that any company you select is insured and is registered with FENSA.
It is crucial to remember that altering your double glazed windows is not advised and could end any guarantees. If you have a warranty on your windows, it's recommended to let the manufacturer know about any problems that arise, as they will be responsible for replacing units that are covered under warranty. Additionally, any damage that is caused by tampering will most likely not be covered by your warranty either, so it is recommended to seek expert advice before making any DIY repairs. This is particularly applicable to older units as they are often more prone to fail. It's best to replace the entire glazed panel in the event of this. This way, you'll have brand-new windows that will last for years.
Scratches
Double-glazed windows aren't immune to scratches. This can be a result of environmental conditions or even caused by the manner in which the window was installed.
Thankfully, many of these scratches are not too severe and can be easily fixed with some do-it-yourself home remedies. If you feel scratches on your windows using your finger or nail, or when they are very deep, you should consult an expert to restore the glass to its original condition.
Superficial scratches are caused by objects scraping against the glass surfaces of your windows such as pet claws, tree branches and abrasive materials utilized when cleaning. These scratches are usually removed with non-abrasive solutions such as iron oxide or polishes made of cerium dioxide. You will require these products until the scratch disappears.
Scratches can also happen when sanding wood trim near your windows. They can also occur during construction. They are difficult to repair, however the use of baking soda and water should help smooth the buffed area and remove any scratches that remain.
Metal polish can be used to eliminate deep scratches. Add a small amount of the product to a microfibre or cotton cloth and gently rub over 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 moist cloth to remove any excess polish residue.
You may want to consider purchasing a non-abrasive glass polish if you have a deep scratch you cannot seem to remove. It can be purchased at any DIY store and should be applied in accordance with the directions on the packaging. You can also use nail polish to smooth the area and cover any shallow scratches on your window glass. Make sure that you only apply the nail polish only to the area scuffed.
Haze
Haze in your double pane window is an indication that the airtight seal between the two glass panes has been damaged. It is essential to get this repaired as soon as you can so that you don't end having dirt and moisture build-up between the panes. This can cause damage to the glass and result in an increase in transparency.
There are several options to remove the haze on your double paned windows. Use a defogging solution. This is only a short-term solution. If you're looking for a long-lasting solution, you should consult an experienced glass company. They can repair the issue or replace the gaskets if required.
Another way to solve haze in double glazed windows is to make small holes in the frame of the window, using a carbide-tipped drill. Then, you can insert a desiccate pack into these holes and wash the window using rubbing alcohol. The water will help to remove the haze as well as clean the window.
To prevent fogging, you must keep your windows clean and maintain them frequently. This will let you see through the double-panes and enjoy the stunning view from 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 sucked away, rather than being allowed to settle and reseal the window.
In addition to the regular cleaning and maintenance, you should also make sure that your windows are correctly installed. The installation of your windows should be done by a glass company with expertise. This will ensure that the seals and gaskets are fitted correctly, and that they fit tightly. It's also recommended to get your windows repaired as soon as you can before they begin to exhibit signs of wear and tear.

In general, double-glazed windows with insulation are built to last for around 20 years. This is because they're designed to withstand all kinds of conditions like extremely cold temperatures, extreme humidity, heat and frequent opening and closing. It is essential to remember that an improper installation or defective materials can decrease the life span of double-glazed windows.
