Necessary tools

STEP 1
Whether you’re working on a tilt or non-tilt window sash, you’ll need to remove it to safely and efficiently replace the glazing bead.

STEP 2
Lay the sash on a table against a wall or other stationary surface so that the sash will not move as you work on it. Coming in from the side, wedge the chisel in between the window frame and vinyl glazing bead to create leverage for removal.

STEP 3

CONTRACTOR TIPS

If the existing leg of your glazing is on the longer side, you may have trouble removing it as shown in our tutorial.

If that is the case, using a slotted screwdriver to pry the glazing straight up and out of the sash is the best way to prevent further damage.
