Quietly, all the while I work on the NE corner or the stairhall niche, for example, there is almost a window sash in the basement workroom being restored.

And by this baby step method, about 80% of the windows in the house have now been restored. Which amazes me, as when I purchased the house in 2014 the idea of restoring sooooooooo many ancient sashes was overwhelming. For a brief period, early on, I actually wondered: would replacement windows really be so bad?

I know. Please don’t tell anybody.


The final third-floor windows are being done. This sash is from the east dormer. All the not-too-old glazing has been removed. The wood will then be stripped of paint, then disk-sanded. For glazing I use this, which a reader recommended, and I LOVE IT! The stuff dries in about a week! Which is way way way less than what I had been using for forty years. NOTE: Only buy a quart. The gallon will dry out about 1/2 way through.


Another sash newly primed. As you can see, no effort is made to create a straight edge on the glass. After the final coat is done, a 6-inch putty blade, and a sharp straight-edge razor blade, will be used to create a fabulously precise edge. And, oh baby, do I love a fabulously precise edge.

    How many sashes does a quart do? I have one to do soon.

    Wow! I had been wondering how you restore windows. I have many original 1923 windows. They are beautiful and I love them but they could use a little more love.

    Looking good Ross!

    Looking good, Ross! I have heard others say that Sarco Type M is good stuff, so it’s nice to hear some confirmation. I may give it a try when I do the windows on our current house. I used ordinary Dap33 on our last place, and just did them in batches in the basement and waited patiently for the putty to skin over. It was a good exercise in patience 😉

    I used just a little over a gallon on that moderate foursqure, so I imagine you will have used several gallons of putty by the time you are finished with your place! I bet the diamond sashes used a lot by themselves!

    Never ceases to amaze me the amazing craftsmanship!

    Sigh…. I love you and I hate you, as you have raised my aesthetic (is that the right word?) sensibilities and I will never again be satisfied with replacement windows. Have you ever thought about youtubing your restoration projects? I bet you’d get quite a following, and perhaps some income from doing so. I’d love to watch you work and hear more about why you choose the products and techniques you use, etc… Thanks for all you do!

    Replacement windows? Seriously?? I am shocked, appalled, and thoroughly disillusioned here. Next thing I know, you will confess to being a closeted republican…

    Seriously, thank you for sharing the advice and tips. I have been frustrating over my attempts to paint the new glazing in my old windows, the painters tape pulls some of the paint off with it. I’m glad you shared this now, instead of a few months from now after I have (hopefully) finished. You really should compile all of your techniques into a DIY-How To book, I’d stand in line for the first copy 🙂
