Once upon a time, before Old Home Rescue, we were Wood Window Rescue. We’ve spent the years, scraping every last piece of paint, reglazing each panes, and re-roping windows. I’ll be honest, even as a professional, sometimes it’s hard. It’s a common topic at our window restoration workshops as well as Facebook groups like Our Old House. What we’ve learned, and now stress, to our Neighbors is that there is a time and a place for window restoration. Sometimes it’s best for your time, your marriage (seriously), and your windows to just perform paint maintenance.
Below is the process that we have specifically developed for our painters to paint old wood windows WITHOUT removing the paint to bare wood or the window from the opening. Yes, it will have continue to have the character of an old home, but when viewed from the sidewalk, the paint will look amazing and be eligible for Sherwin Williams’s lifetime warranty. If you do want to remove it to bare wood and deglaze, we highly recommend using a Speedheater over a heat gun and check out this video.

The following process is intended to be the final step in a Lifetime Exterior Renovation. This is the difference between putting color on a house and prepping & painting a home where we can all stand behind the quality of work.

Notes on Painting Wood Windows
The above specifications are for painting wood windows for stabilization, protection and maintenance on a cyclical basis. Window painting’s cosmetic results should be viewed from the sidewalk as there will be inconsistencies in the paint surface.
If the Neighbor is interested in additional surface preparation or results, direct them to the Old Home Rescue Project Manager, who will discuss on-site restoration, off-site restoration, or reproduction windows.
