How to Seal Drafts Around Windows Before Winter
To seal drafts around windows before winter, first locate the air leak, then match the repair to the part that moves: use caulk for fixed gaps around the frame and weatherstripping for joints around an opening sash. Window insulation film can cover a leaky window as a temporary seasonal measure when the gap itself is difficult to repair. Key Takeaways Test the sash, frame perimeter, and trim separately so the repair goes in the right place. Caulk seals stationary joints; weatherstripping seals parts that open and close. Use window film as a removable seasonal layer, and investigate rot or a distorted frame before covering it.
