We have a 1926 Craftsman house outside of Baltimore, MD. The inswing wood casement windows in the sunroom are original and we want to restore them. After removing the old caulk and paint that had sealed them shut and replacing the hardware, the windows now open and close and the next step will be to sand and repaint. However, we now have noticed that several of the windows leak water into the house during heavy rains. There is old metal weatherstripping that appears to be intact and we have no idea how the water is getting in. Any ideas for how to repair or replace the weatherstripping to make them watertight?
