How to replace the plastic beading for windows
The glazing that holds glass panes in wooden windows eventually needs replacing. (Jupiterimages/ Images)

Over time, window glazing compound can become brittle and unsightly. When pieces of the glazing fall out, the window may become loose in its frame. Replacing glazing compound is simple and inexpensive. No special tools are required and you can complete the job in a couple hours.

  1. 1

    Pick off any loose chunks of old glazing compound around the window with a putty knife. Soften any stubborn glazing compound fragments with a heat gun or hair dryer, then pry or scrape the putty from the window and frame. Remove any residual particles of putty or dirt with a stiff brush. If the window is not held securely in place, insert glazier's points to hold the window tightly to the frame. Hold the flat side of the point against the window and push it toward the frame. If the wooden frame is especially dry or hard, push the point with the end of the putty knife.

  2. 2

    Roll some glazing compound into a long "rope" that's about the same diameter as a number 2 pencil. Press the compound into the corners where the window meets the frame. Continue making putty ropes and pressing them to the window until the putty forms a complete border around the window.

  3. 3

    Dip your index finger in water and smooth the putty to form a tight seal between the window and the frame. As you work, wipe excess putty from your finger, window or frame. Allow the glazing compound to dry thoroughly, according to manufacturer's directions.
