How to Repair a Double Glazed Window
Double glazing is a cost effective way to make your home more energy efficient and to increase its energy efficiency. It is susceptible to problems such as condensation and draughts.
While replacement is the most obvious solution to these issues, repairs are often a much more affordable alternative. Let's look at a few of the most common solutions for repairs to double-glazed windows:
Broken Panes
The first step is to remove the broken pane from the frame. Wear thick work gloves and set up an empty cardboard box in the vicinity to catch any glass fragments that fall during your work. Wear a protective eye mask and mask due to the possibility of lead being in the frame. Use a utility blade to cut the glazing surrounding the windowpane that has been broken. If upvc window repair or clips are holding the windowpane in, use pliers to pull them out. Scrape off any old putty or glazing points after the glass is removed. A heat gun can be used to in softering the putty if you need to.
After the old putty has been removed then re-grout the grooves and apply silicone caulk using a silicone caulking tool. Before applying the final caulk it's a good idea to test fit the new window into its frame. Make sure that the grooves are clean of any rust, gunk or paint and that they aren't too narrow for the windowpane to sit in.
Next you should replace the sash with a wood molding that matches the frame of the window. If the frame of the window is damaged, it may be easier and more cost effective to replace the entire window unit rather than a single pane.
In the past, double pane windows were made of two pieces of glass separated by the help of a spacer. They were then filled with air or an gas used to insulate. In recent years, companies have changed to insulated glass units (IGs) that are more energy efficient and resistant to seal failure. In a double-pane glass with a damaged IG the moisture from the environmental air seeps into the gap and condenses on the inside of the glass. This cycle eventually breaks down the properties of insulation, leaving an opaque film on the glass.
To fix a damaged IG glass, the glass repair expert can replace the entire unit or can replace only the damaged surface of the glass. This procedure can be costly and time-consuming, however it is the only way to fix the seal that is defective and allows water to leak into the home. Installing windows of high-quality by a technician who has the experience and purchasing windows from a reputable manufacturer will help prevent the possibility of future seal issues.
Misty Panes
The window's frame can hold three or two panes, separated by air-filled spaces. The air, which is often filled with argon to increase energy efficiency and to keep warm air in, helps keep cold air out. Unfortunately, windows can start to break down, and you will see a hazy cloud building up between the panes of the glass. You might think it's time to replace the entire window but it's not as easy as simply removing the broken pane and replacing it.

Condensation between the panes of your windows is a sign there's a lot of humidity in the home It's therefore essential to dehumidify and take other measures to increase ventilation in the areas where this happens frequently. If the condensation is only visible on the side of the window or between the panes, then you'll need to have the seal replaced.
It is not possible to seal a double-glazed windows in order to bring back the original energy efficiency. When the seal breaks the gap lets cold air in your home and warm air out. This will affect the insulation of your home and make it more costly to heat.

Double glazing isn't impervious to damage and even with the best of care defects can occur. Some are minor and can be repaired while others are more serious and require to be replaced completely.

If this is the case, you need to have your windows fixed as quickly as possible to prevent any further damage to your double glazing and to stop water from entering the insulated gap.
Over time, the protective layer that keeps the glass panes in their frames and keeps them from moving can wear out. This could cause one or both glass sheets to move slightly and break the seal, which can cause misting. Mist may also form in the space between the panes that is insulating and the glass, indicating that the seal has broken and it's time to repair double glazing.
Another common issue is that the windows have begun to sag over time, making it difficult to open and close them. This can usually be repaired by adjusting the hinges or mechanisms.

They occur when a gap opens between the two glass panes which causes moisture and air to seep into your home. This is typically a sign of deterioration, or a problem in the insulation material that separates the panes.
Condensation between the panes is another issue that double-glazed windows may cause. This happens when the warm air inside your home is warmer than the outside air. The warmer air expands due to the difference in temperature which can cause window seals to be damaged or break over time.
Double-glazed windows can cause foggy windows. This is a common problem that can be solved without replacing the IGU. This is usually a sign that the seals between your window's panes require resealing.
To accomplish this, you'll have to drill an opening between the panes of your window.
