How to Repair Double Glazed Windows
Double glazing is usually covered by a warranty of 10 or 20 years. If your double-glazed windows are showing signs of ageing you may be eligible to have them repaired under warranty.
Double-glazed window repair s require replacing the glass unit that is in use. The seal isn't working properly when you notice mist.
Damaged Glass
A seal that is airtight is vital for double pane windows to function properly. The most typical sign that a seal is failing is the formation of condensation between the glass plates. While condensation between glass is not a serious problem and can be addressed, it's usually an indication that the glazing unit needs to be replaced. If you have an older double-glazed window, this may require replacing both the glass and the frame. If your frame is still in good shape it is possible to save money by only replacing the glass.
Double-paned windows can crack because of the fragility of glass. If the cracks aren't caused by mechanical damage or a sudden impact, it's often possible to repair these cracks with epoxy and a little bit of elbow grease. Follow the directions of the manufacturer and clean the cracked area with a moist cotton cloth. Then, apply epoxy to the crack. Allow the epoxy to completely dry before sanding and painting over the repaired area.
A simple strip of masking tape can be used to keep cracks from spreading. A single strip of masking tape on both sides of the crack ought to suffice to stop cracks that are superficial from spreading, for instance stress-cracks that are caused by low temperatures. If you notice more severe cracks in your glass that are already present, it's recommended to speak with an expert for repair.
It is risky and difficult to replace a single pane in a double-paned window. Double-pane windows are manufactured as a complete unit and sealed at the factory using inert gas, which means it is impossible to remove the glass without causing damage to the entire window. If you intend to replace the glass in your double-paned windows pick a manufacturer with an extensive warranty.
You can also apply newspaper to protect the window frame prior to deciding to remove the sash, or replace any broken glass. This will help protect yourself from sharp shards that could fall during the process as well as to protect the trim of your home or molding.
Condensation Build-Up
The good fact is that condensation between windows is completely normal. This is caused by the difference in temperature and humidity of the air. The water vapour in air is condensed when it comes into contact with cold, inaccessible surfaces like windows. It's usually a good thing, especially in winter as it can help prevent heat loss.
However, if you're noticing that your windows appear cloudy and have a layer of moisture on them, it's the time to contact an expert Glazier. This indicates that the seal between the two panes is beginning to degrade and allows moisture to enter the window.
You can stop this from happening by using dehumidifiers, enhancing ventilation, or by applying de-icing agents. There are also specialists who can solve condensation issues in double glazed windows by drilling holes into the window unit and pumping or injecting a specific desiccant to eliminate the excess moisture. This involves taking the sealed unit out of the frame and cleaning every glass pane before refilling the desiccant. This will usually be a more expensive option but it's worth checking that any company you select is insured and is registered with FENSA.
Be aware that any modification to your double-glazed windows can end any warranties. If you have a guarantee on your windows it's always recommended to let the company know about any problems that arise as it will be accountable for the replacement of units covered under warranty. Also, any damage incurred by tampering will most likely not be covered by your warranty, so it's better to seek expert advice before making any DIY repair. This is particularly relevant for older units since they are sometimes more susceptible to fail. It is recommended to replace the entire glazed panel in case this happens. Then you'll have brand new windows that will last for years to come.
Scratches
Double glazed windows are not impervious to scratches. This could be due to environmental factors, or the manner in which the window was constructed.
Many of these scratches are minor and can be repaired by using a few home remedies. If you can feel the scratches on your windows using your fingernail or if they are deep, you should seek out an expert to repair the glass to its original condition.
These scratches are caused when objects like tree branches, pet nails and cleaning products that are abrasive scratch the glass of your windows. Usually, scratches can be removed with some non-abrasive solutions such as iron oxide or cerium oxide polishes which you'll have to keep using until the scratch is no longer visible.
Scratches can also occur while sanding wood trim near your windows. They can also happen 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 remove deep scratches. Add a small amount of it to a cotton ball, or a clean microfibre cloth and gently rub the affected area in a circular manner. Be cautious not to apply too much pressure, as this could cause damage to the glass. Once the area is smoothed, apply a damp cloth to remove any polish residue.
If you have a particularly deep scratch that you cannot remove, you should consider buying a special non-abrasive glass polish. This is available at any DIY store and must be applied according to the instructions on the product packaging. Alternatively, you can 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 only to the area that is scuffed.
Haze
Haze in your double pane window is a sign that the airtight seal between the two panes of glass has deteriorated. This must be fixed as soon as you can so that moisture and dirt don't build up between the glass panes. This can cause damage to the glass and lead to a reduction in transparency.
There are several ways to fix the haze that has formed on double pane windows. One option is to use a spray to defog the windows. However, this is only an interim solution. If you are looking for a permanent fix, you should contact an experienced glass company. They can fix the issue or replace the gaskets as needed.
Another way to get rid of the problem of 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 desiccate packs into these holes and wash the window using rubbing alcohol. The water will help remove the haze from the window and clean it.
To prevent fogging, it's important to keep your windows clean and maintained by cleaning them on a regular basis. This will let you see through the double panes and enjoy the stunning view from your garden or home. Also, ensuring that your house is ventilated can also be beneficial. This will help to ensure that any condensation is quickly removed, instead of being allowed to settle and then reseal the window.

This will ensure that the gaskets are installed properly and have an exact fit. It's a good idea to repair your windows as quickly as possible before they start showing signs of wearing out.
