The document is a series of cautionary tales and warnings about what can happen when wood windows and sashes are not properly maintained. It warns that weathered wood and peeling paint are signs of neglect and that water, sloppy painting, unmaintained hardware, failed glazing putty, and dry rot are "not your friend" and can lead to deterioration and the need for replacement if the windows are not properly cared for and maintained. It stresses the importance of regular maintenance to prevent wood windows from "going bad."
