This can be done without replacing the windows and will be much less expensive in the long term. However, specific tools are required and it is best to have a professional take care of this type 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 can be worn out over time. If you've broken a seal, outside air is entering your home and the argon that helps to insulate your home is being emitted both of which can be detrimental to energy efficiency.
The reason window seals break is because they are exposed to extremes of temperature and humidity, as well as pressure. These changes can make your window glass to expand and contract. This can put pressure on the seals. This is also a possibility when you have pets or children that accidentally hit your windows.
If the seal on your window breaks it's best to have the issue examined by a professional as quickly as possible. If you delay too long, the argon gas or krypton may escape completely and reduce the insulation properties of your window.

However, if this spacer bar becomes saturated with moisture it can start to leak into the frame of the window which is where the condensation develops.
