Glass Selection

The Replacement Procedure

With preparations complete, let’s get down to the real action.

Removing Old Glass

Carefully pry away broken glass pieces. Use the chisel or putty knife, but remember: patience is a virtue.

Prepping the Window Frame

Once the old glass is out, it’s cleanup time. Remove all old putty and any lingering glazing points to create a welcoming space for your new pane.

Slide in the new glass piece gently. Secure it using glazier’s points.

Sealing and Finishing Touches

A well-sealed window stands the test of time. Apply fresh putty around the edges, smoothing it out for a clean finish.
