How to Repair Double Glazed Windows
Typically, double glazing comes with a guarantee of 10 or 20 years. If your double glazed windows are showing signs of ageing you could be eligible to have them fixed under warranty.
Double-glazed window repairs involve resealing the existing glass unit. Misting is a clear indicator that the seal has failed and you need to have it fixed.
Glass damaged
A seal that is airtight is crucial for double pane windows to work effectively. The condensation between the glass plates is a common sign of a failing seal. Condensation between glass plates is not a major problem and can be corrected however it is a sign that your glazing unit needs replacing. 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 it is possible to save money by just replacing the glass.
Double-paned windows can develop cracks because of the fragility of glass. If the cracks were not caused by mechanical damage, or a jarring impact to the window it is possible to repair them with epoxy and some elbow grease. Begin by cleaning over the crack with a damp cotton rag and then apply epoxy to the crack according to the instructions of the manufacturer. Allow the epoxy to completely dry before applying paint and sanding to the repaired area.
It is also possible to stop a crack from spreading with the use of a strip of masking tape. One strip of tape on both sides of the crack area is enough to keep superficial cracks, such as stress cracks that result from low temperatures, from getting worse. If you notice deeper cracks in your glass that are already present, it's recommended to consult an expert for repair.
The process of replacing a single pane of double-pane window glass is a risky and difficult DIY job. Double-paned windows are made as a complete unit and sealed with inert gases in the factory. Therefore, it is impossible to take off just the glass without damaging the window. If you intend to replace the glass in your double-paned windows pick a manufacturer with a long-lasting warranty.
You can also use newspaper to protect the window frame prior to when you remove the sash or replace any broken glass. This will shield your from any glass shards that could fall in the process. It also helps prevent any damage to the molding or trim of your home.
Condensation Build-Up
It's good to know that condensation in the windows can be normal. It is caused by the difference in humidity and temperature of the air. The water vapour in air condenses when it comes in contact with cold, inaccessible surfaces like windows. This is usually a great thing during winter because it helps prevent the loss of heat.
If your windows appear like they are cloudy and have a thin layer of water on them, you must contact a professional glazier. This is a sign that the 'air gap seal between two panes of glass has started to degrade and is letting moisture into the window.
You can stop this from happening by using a dehumidifier or a fan, enhancing ventilation, or using a de-icing agent. There are also companies that can remove excess moisture from double-glazed windows through drilling into the frame and injecting desiccant. This requires taking the sealed unit out of the frame and cleaning every glass pane before refilling the desiccant. This is typically more expensive, however it's worth checking that any company you select is insured and registered with FENSA.
It is crucial to remember that tampering with double-glazed windows isn't advised and could end any guarantees. If you have a guarantee on your windows it's always best to let the company know about any problems that arise, as they will be responsible for replacing units that are covered under warranty. Also, any damage incurred by tampering is likely not be covered under your warranty either, therefore it's best to seek advice from a professional before making any DIY repair. This is especially relevant for older units since they are sometimes more susceptible to fail. If this happens, it's probably best to replace the whole glass panel. Then you'll have brand new windows that will last for years.
Scratches

These scratches are caused when objects like pet nails, tree branches, and cleaning materials that are abrasive scrape against the glass of your windows. Often, these scratches can be cleaned with some non-abrasive solutions like iron oxide or cerium oxide polishes, which you'll have to keep using until the scratch is not visible anymore.
Scratches may also occur when you sand wood trim around your windows. They can also occur in the course of construction. These scratches can be difficult for you to fix. However, a mix of baking soda and water can aid in smoothing out the buffed surface and remove any remaining scratch.
Metal polish can be used to eliminate deeper scratches. Add a small amount the product to a microfibre ball or cotton cloth and gently rub the affected area in a circular 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 remaining polish residue.
Think about purchasing a non-abrasive glass polish if there is a a deep scratch you cannot get rid of. It can be purchased at any DIY store and must be applied following the directions on the packaging. You can also use nail polish to smooth the area and cover any small scratches on the glass of your window. Make sure that the nail polish is clean and that it is only applied to the scuffed part of your window.
Haze

If you are looking for a permanent solution, you should consult a professional glass company. They can repair the issue or replace gaskets as needed.
Another way to solve the problem of haze on double-glazed windows is to make small holes in the window frame, using a carbide-tipped drill. You can then tuck in a desiccate bag into these holes and wash the window with ruby alcohol. The water will clear the haze as well as clean the window.
