Steps to Replace Broken Glass Pane

  1. Gather Supplies, Protective Clothing: Gather together the necessary supplies for the job. With broken glass panes, it is important to make sure you keep safe while replacing the window pane. Wear protective clothing, including protective gloves, a long sleeve shirt, pants, closed-toe shoes, and protective eyewear.
  2. Remove Glass from the Window: Piece by piece take out the broken glass shards from the window pane. Be cautious and careful when removing the glass; make sure not to cut yourself or drop glass on the ground. A floor covering is a good safety precaution to prevent small glass particles from falling on the ground where you may step.
  3. Remove Old Putty or Caulking: This step is one of the most time-consuming steps of the whole process. With a utility knife, carefully lift the old putty or caulking from every side of the window pane. The putty in some windows may be easier to remove than others. Be sure all the putty is removed and make sure there are no bumps in the window pane. As you remove the old putty, be careful not to damage the paint or the window pane itself.
  4. Remove Triangular Nail Fasteners: In addition to removing the putty, use pliers to remove the old nail fasteners along the window pane as well. The window fasteners hold the window in place, so it is important the old ones are replaced with the new ones. Each window may have different amounts of nail fasteners, depending on who installed the window, but there are generally about two or three on each side of the window pane.
  5. Measure Window Opening & Order Glass: Once the window pane has been properly prepped, measure the size of the window opening to know the glass dimensions. Each piece of glass should be about an eighth of an inch less than the opening, to easily fit the glass to the window pane. Make sure the glass is also the right thickness to fit within the window frame.
  6. Dry Fit Glass to Frame: Once you have received the glass for the window, dry fit the piece of glass to the window pane to be sure it will fit properly. After checking the glass, put the new piece of glass aside for the moment.
  7. Add New Glazing & Place Glass: With the prepped window pane, free from bumps or other debris, add a thin new layer of glaze or putty around the entire window pane. The glazing helps to keep the window weather-tight. Place the glass in the window pane.
  8. Replace Nail Fasteners: Nail fasteners hold the window in place. Add the new nail fasteners to the window pane to replace the old ones. Gently bend the tip of the fasteners to hold the glass snug in place. If there is too much pressure or force, there is a chance you could break the new piece of glass; so be gentle. The glass shop will not replace the glass you accidentally broke for free.
  9. Add More Putty: Once the glass has been set in the new glaze and the nail fasteners have been replaced, add another layer of putty against the window pane. Put a little putty on your putty knife, and do a little section at a time. Don’t worry about making it aesthetically perfect in your first shot; you can smooth and clean it up in the next step.
  10. Straighten Up & Paint: Time for the finish work. Take the painter’s tool at an angle and smooth the outer caulking. Then align the top of the caulking or putty so it is the same width and height all the way around the window. Apply at least two layers of paint to the putty to finish. Do not worry about getting a little extra paint on the glass, because it can easily be scratched off.
