Seals that are damaged
The seals on windows can wear down over time and allow argon gas or krypton to escape from between the panes of double- or triple-paned windows. If you've got a damaged seal, outside air is entering and the argon that helps to insulate your home is escaping both of which are bad for energy efficiency.
The reason window seals break is that they are exposed to extremes of temperature and humidity as well as pressure. These changes cause your window glass to expand and contract, which puts a lot of pressure on the seals over time. This can happen if your pets or children accidentally hit your windows.
If the seal on your window breaks it's best to have the problem investigated by a professional as soon as you can. If you put off the repair for too long, the argon or krypton gas might escape completely, and this could significantly diminish your window's insulating properties.

Condensation
Condensation is a potential issue when double glazing is used. This is particularly true in older properties. It happens when the air in a home has more dewpoint and is warmer than the glass, causing condensation to occur. It is more likely to occur at late at night or in the early morning hours, when temperatures are at their lowest.
Condensation issues in double-glazed windows can be easily fixed and it is not necessary to replace the entire window or door. The spacer bar found between the two glass panes in the majority of double glazing is filled with desiccant, which is highly absorptive and absorbs any moisture that enters the 'air gap. If this spacer bar is saturated with moisture, it may leak into the window frame where condensation develops.
It is also important to remember that most double-glazed windows are still under warranty and must be reported to the company who installed the windows. They will investigate the issue and replace any units or seals that have become damaged. Do not try to alter the units as this may invalidate 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 functioning correctly keeping damp and moisture from your home. The presence of mist in your windows is a more serious issue and could indicate that one or more seals are damaged.
To make the double-glazed window waterproof and airtight, the gap between the two panes needs to be sealed with gas argon. If the glass appears to be misted, this suggests that the argon has been damaged or a seal has broken. This can be an indication of poor installation because the window might have been damaged during the process, or the sealant may have worn away over time.

Many companies claim to be able to repair misted double glazed windows by drilling holes in the glass and pumping chemicals through them to remove the water vapour and fog from the inside. This is a viable option for many but it's crucial to understand that there are limits to what can be fixed.
Sometimes, a replacement is the best choice. This is particularly true when there are major damage. Broken panes, rot or extensive damage could indicate that the window unit is no more functional and should be replaced with something newer, better and more energy efficient. A professional consultation is recommended in these situations to determine the most effective course of action.
