This is a more cost-effective solution than replacing windows. This type of repair requires very specific tools and equipment, so it's recommended to leave this work to professionals.
Seals that are damaged
The window seals can be worn down in time which allows argon gas and Krypton to escape between the panes of double or triple-paned windows. If you have a broken seal, air from outside is getting in and the argon which helps insulate your home is being emitted and both are detrimental to energy efficiency.
Window seals are susceptible to damage due to extremes in humidity, temperature and pressure. These changes can cause your window glass expand and expand and contract. This puts pressure on the seals. This is especially true if you have pets or children who can accidentally bang against your windows.
If your window seal is damaged it's best to have the issue investigated by a professional as quickly as possible. If you put off the repair for too long for too long, the argon and krypton gas may escape completely, and this will significantly reduce your window's insulating properties.

However, if the spacer bar becomes filled with moisture, it may begin to leak into the frame of the window. This is where the condensation forms.
