Double Glazed Windows Repairs
If your double glazed windows are hard to open or have a haze between the panes this could be an indication of damaged seals. If this is the case, it might be worth arranging for them to be repaired.
This can be accomplished without replacing the windows and is a lot less expensive in the long term. However, very specific tools are needed so it is recommended to let a professional handle this kind of repair.
Damaged Seals
Window seals are what keep the gas argon or Krypton between panes of glass in triple-pane or double-pane windows, and they may be worn out over time. A broken seal allows outside air to pass through and the argon gas that insulates your home to escape. Both of these are detrimental to energy efficiency.
Window seals can be damaged by extremes in humidity, temperature and pressure. These changes cause the glass to expand and contract, which places lots of pressure on the seals over time. This is also a possibility when you have pets or children who can accidentally smash into your windows.
When your window seal breaks it's best to have the issue examined by a professional as fast as you can. If you wait too much and the argon gas or krypton gas could escape completely and lower the insulation properties of your windows.
Fog that forms between the window panes is a common sign of a failing seal. While it's possible to solve this yourself by defogging the area, the most effective solution is to hire a professional to come out and reseal your window.
If you are having your windows resealed, a technician will remove the old seal, clean the panes and put in the new seal. The technician will remove the sash, if needed, then reassemble it and replace the IGU (insulated unit) if necessary. Then, they will re-insert the argon (or Krypton) into the void in between the panes. They will also re-seal the IGU to create watertight sealing. You can purchase kits that claim to help homeowners with this process. Reviews for these products are mixed however, and we generally recommend leaving this task to experts.
Condensation
Condensation is a concern when double glazing is used. This is particularly true in older properties. It occurs when the air in a home has a higher dewpoint and is warmer than the glass, leading to condensation to occur. This is likely to occur at late at night or early in the morning, since the temperatures are typically at their lowest.
repairing double glazing in double-glazed windows can be easily fixed, and it is not required to replace the entire window or door. The spacer bar located between the two glass panes in the majority of double glazing is filled with desiccant which is highly absorptive and absorbs any moisture that comes into the 'air gap. However, if the spacer bar is filled with moisture, it may start to leak into the frame of the window, which is where condensation forms.
It is also worth remembering that the majority of new double-glazed windows are still under guarantee, and should be reported to the company who installed the windows. They will investigate the problem and replace any seals or units that have become defective. Don't attempt to modify the units as this may affect your warranty.

Mist
Condensation on the exterior of your double-glazed windows is nothing to worry about, as it's a sign that your windows are operating correctly and are keeping damp and moisture out of your home.
