Broken Panes

The ball-shaped end of the tool can be used to break the fragments. They should come off quite quickly.

After the glass has been removed, scrape off any glazing compound that is old from the recess area of the frame. This will expose the glazier's point and the metal clips that hold the pane in the frame. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is made of wood, the glazier's points can be used again if they're in good condition.

The surface of the remaining frame will need to be prepared to allow re-glazing. Apply a continuous strip of compound to the recess using a caulking tool. Use a high-quality putty such as a glazier’s compound in a cartridge. Allow it to dry before re-inserting the glass. If the frame has metal clippings, they must be reinstalled too. Finally, install the dividers.

Condensation

If the seal is blown it allows water vapour to pass through your home through the gap, which will cause condensation between the panes which cannot be wiped off.

This is a straightforward issue to repair and windows can be quickly replaced by specialists with the right tools.
