How To: Reglaze Your Old Windows

By The Craftsman on Oct 22, 2012

Window Reglazing Learning to reglaze your old windows is something that scares the pants off of many homeowners. But fear not! It does require practice and a bit of an artist’s touch to get it just right, but like anything, practice makes perfect. You can learn to reglaze your old windows yourself with just a little practice and some good training.

However, describing how to reglaze your old windows in a blog post is a bit like trying to teach someone to dance via cell phone. So I’ve put together a short video to walk you through the steps of bedding and reglazing an old window. Along with a few tips and resources I’ve included in this post you should be able to reglaze your own windows with confidence.

 That’s right! The Craftsman now has its own YouTube channel! And we’ll be posting lots more videos to teach you all kinds of new skills. So, stop by YouTube and subscribe to our channel for updates whenever we post a new video. And don’t forget to like our video and share it with your friends if you find it helpful.



    1. Always prime a bare sash with an oil-based primer prior to glazing.
    2. Wear gloves when handling antique glass. It is very brittle and can easily break.
    3. Wait until the glazing putty has formed a skin (usually 1-2 weeks) before you attempt to paint.
    4. Do not prime the glazing putty after you have glazed your window. Just add 2 coats of a quality paint.


    • Sarco Glazing Putty – This is the only brand of glazing putty I recommend. It is linseed-oil based and as close to the old stuff they used to use. If you are glazing your windows in a garage or shop use Sarco Type-M putty. If your windows will be glazed outside and exposed to the elements prior to painting use Sarco Dual Glaze.
    • Diamond Glazing Points These points are the smallest and easiest to hide under the glazing putty which allows you to have the cleanest glazing lines.
    • Silent Paint Stripper – For removing old paint that may contain lead paint this is the method I prefer. It’s expensive, but most things that work well usually are.  *Always use proper protection and follow the EPA’s rules when dealing with lead paint.
    • Glazier’s Tool – For me this tool provides the best angle to get a nice smooth line and allows me to cut in to get perfect (most of the time!) corners.
