A window that is damaged should be repaired by a professional to ensure you get the correct seal and the optimum energy efficiency.

This will reveal the glazier's facets and metal clips that keep the pane in the frame. If there's any indication of corrosion, the clips must be replaced with new ones. If the window is constructed of wood, the glazier points can be reused if they're still in good shape.

The next step is to prepare the surface of the frame for re-glazing. Apply a continuous strip compound to the recess with a caulking tool.
