Most single pane window glass is held in place with glazier’s putty and, oftentimes, small metal clips called glazier’s push points. Perhaps the most challenging part of this job is removing the old putty which, can, at times, be quite hard. In this video I show you how to cut your own glass to size, however, you can also get many hardware stores and home improvement centers to cut it for you. Always order the glass cut slightly small than the opening.
Glazier’s window putty can be quite sticky stuff. Kneading it in your hand and rolling in into a coil before applying it can make it a bit more obedient. Smoothing the putty after putting it in place is really a matter of practice. If it’s not turning out as neatly as you’d like, scrape it out and try again. It’s really a matter of holding the putty knife at the right angle and applying even pressure.
