Pane in the sash
Repairing old window sashes can seem pretty low-tech, and it might be one example where old-fashioned materials make the job a little more forgiving. First, remove the old putty and clean up the rabbet for the glass. Before attempting to pull the pane, make sure that you have removed any hidden glazing points or brads. For removing old putty, a chisel or a stiff putty knife works well. Heat can help to soften the putty, but you need to be careful not to crack the glass.
Window dressing Add linseed-based glazing putty to the rabbet, then lay in place the glass. Secure it with glazing points. You will have to work the putty in your hands to soften it and keep it workable.
More putty Apply a generous amount of putty to the rabbet on top of the glass, then use a putty knife to shape it. Draw the knife along, at an angle, so that the remaining putty covers the rabbet on the other side of the glass.
High security Latex-based glazing caulk is available in a tube that simplifies application. Simply apply a bead into the rabbet to bed the glass, secure with glazing points and then apply another bead on top. You can shape the latex glazing with a putty knife, just like linseed putty, but it is very soft, at first getting a nice result can take some practice.
