Step 3 · Install New Glass Pane

Measure the opening precisely after cleaning the rebate. Order or cut a new glass pane to fit. Carefully place the new glass pane into the cleaned rebate. Ensure it is centered and has even spacing all around. Insert glazing points every 6-8 inches around the perimeter to hold the glass securely in place. Next, apply glazing compound (putty) around the edge of the glass, pressing it firmly into the gap between the glass and the sash. Smooth the compound with a putty knife to create a neat, beveled edge, ensuring it extends slightly over the glass and onto the sash for a good seal.
