To begin repairing a broken glass window, put on protective gloves and eyewear. Using a cloth or Hoover, clean up any remaining glass shards. Apply a bead of clear silicone caulk along the window frame's edges. Press a new glass pane carefully into place and fasten it using the glazier's points. Finally, seal the glass by applying extra silicone caulk around the borders. For detailed information visit the blog post about how to replace a broken glass window.
