In the majority of instances replacement of the glass unit is required especially when one or both panes has been broken. If the frame is still in good shape, then fixing only one glass pane could be a viable option.
Masking tape or duct tape are quick and easy ways to seal the cracks. For cracks that are superficial like stress cracks due to differences in temperature one strip of tape over both sides of the window will be enough. For more severe cracks, like those caused from impact, it is recommended that the tape be extended to the length of the crack to ensure that it is able to keep the glass in place.
A solvent-based glass glue is another option for a permanent fix. It is typically applied to both the inner and outer surfaces and then spread with the help of a putty knife. This technique is more time-consuming than using masking tape, but it is more effective in preventing the cracks from spreading.
If the cracks are serious or have been present for a long period of time, it might be better to wait for a professional firm to fix the windows as this will likely result in a more durable finish.
