Glass that is damaged

While condensation between glass is not an issue that is serious and can be dealt with, it's typically a sign that the glazing unit needs to be replaced. If you have a double-glazed window that is older, it may be necessary to replace both the glass as well as the frame. If your frame is in good shape however, you can typically save money by replacing just the glazing.
Double-paned windows can crack because of the fragility of glass. If the cracks weren't caused by mechanical damage or a jarring impact to the window it is possible to repair them with epoxy and some elbow grease. Follow the directions of the manufacturer and scrub the area of the crack using a wet cotton cloth. Then, apply epoxy to the crack. Let the epoxy completely dry before sanding and painting the repaired area.
It is also possible to stop a crack from spreading with a simple strip of masking tape. A single strip of tape on both sides of the cracked area should be enough to stop superficial cracks, such as stress cracks caused by low temperatures, from worsening. If you're dealing more serious cracks that have already formed in your glass, it may be advisable to consult an expert to ensure the security of the repair.

You can stop this by using dehumidifiers, enhancing ventilation, or using de-icing agents. There are also specialists who can fix condensation build-up in double-glazed windows by drilling holes in the window unit and then injecting or pumping a special desiccant in order to eliminate the excess moisture. This requires removal of the sealed unit from the frame and then cleaning each glass pane before refilling the desiccant. This is usually an expensive option, but it's important to check that the business you choose is insured and registered with FENSA.
