Glass damaged
A seal that is airtight is vital for double pane windows to work effectively. Condensation between the glass plates is a typical indication of a failing seal. Condensation that forms between glass plates is not a major problem and can be fixed, but it's an indication that your glazing unit needs replacing. If you have an older double-glazed window, this could mean replacing both the frame and the glass. If your frame is in good condition however, you could usually save money by replacing only the glass.
Double-paned windows can crack because of the fragility of glass. If the cracks aren't caused by mechanical damage or an unusual impact on the window, they can be repaired by using epoxy and elbow grease. Begin by cleaning over the cracked area with a damp cotton rag and then apply epoxy to the crack, following the manufacturer's instructions. Allow the epoxy to dry completely before sanding down and painting over the repaired area.
It's also possible to keep a crack from spreading with the use of a strip of masking tape. One strip of tape on both sides of the damaged area is enough to prevent superficial cracks, such as stress cracks that result from low temperatures, from worsening. If you're dealing with deeper cracks that have already formed in your glass, it may be best to call a professional to ensure the safety of the repair.
It is dangerous and difficult to replace a single pane within double-paned windows. Double-pane windows are constructed as a complete unit, and sealed in the factory using inert gas.

Condensation Build-Up
The good part is that condensation occurring between windows is completely normal.

This is generally a good thing in winter, as it helps prevent loss of heat.
If your windows look cloudy and have a film of water on them, you must contact a professional glazier. This is a sign that the 'air gap seal between two panes of glass has begun to weaken and is allowing moisture to enter the window.
You can stop this from happening by using dehumidifiers, improving ventilation, or applying de-icing agents. There are also companies that will remove excess moisture from double-glazed windows through drilling into the unit and injecting desiccant. This requires removing the sealed unit from the frame and cleaning each pane of the glass before refilling the desiccant. This is typically an expensive option, but it is worth checking whether the company you select is insured and is registered with FENSA.
