This is a far cheaper option than replacing the windows. However, specific tools are required, so it is best to have a professional take care of this kind of repair.
Seals that have been damaged
Window seals are what keep the gas argon or krypton between the glass panes in double or triple-pane windows, and they may get worn out as time passes. A damaged seal allows air from outside to enter and the argon gas that insulates your home to escape. Both of these are bad for energy efficiency.
Window seals can be damaged by extremes in humidity, temperature, and pressure. These changes can cause your window glass expand and expand and contract. This can put pressure on the seals. This is also a possibility in the case of pets or children that accidentally smash into your windows.
If the seal on your window breaks it's best to have the issue examined by a professional as quickly as you can. If you delay too long, the argon gas or krypton could escape completely and reduce your window's insulation properties.
Another indication that the seal is failing is seeing fogginess between your window panes. You can remove the fog from your window however, it is recommended to get a professional out and seal the window.

Then, they will re-insert the argon (or krypton) into the void between the panes. They will also re-seal the IGU to ensure a watertight seal. You can purchase kits that claim to assist homeowners in this process. Reviews for these products are mixed however, and we would recommend leaving this job to professionals.
Condensation
Condensation is one of the most frequently encountered issues when it comes to double glazing, particularly in older buildings. It happens when the air in a home has higher dewpoints and is warmer than the glass, leading to 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 fixed easily, and it is not required to replace the entire window or door. The spacer bar, that is situated between the two panes in the majority of double glazing, gets filled with desiccant. This is highly absorbent and will capture any moisture that enters into the void that is the 'air gap.' If the spacer bar is saturated with moisture, it can leak into the window frame where condensation can form.
It is also important to remember that the majority of new double-glazed windows are still under warranty and must be reported to the company who installed the windows.

Condensation outside of your double-glazed windows isn't a cause for concern since it is a sign that they are working correctly and preventing moisture from your home. Mist inside your windows is a more serious issue that indicates one or more seals have been damaged.
The gap between the two glass panes in a double glazed window must be sealed with argon gas to make the whole unit airtight and water resistant. If the glass is misted it could be because the argon gas is damaged or the seal was broken. This could be an indication of a poor install, since the window may have been damaged in the process, or the sealant could have worn away over time.

While this is a feasible solution for the majority of people but it is important to recognize that there are limitations to the repair options available.
