How to do it — step by step
Close each exterior door and check for light gaps around the edges. Feel for drafts on windy days. Test with a piece of paper — if you can pull it out easily while the door is closed, the seal is failing. Peel off old weather stripping and apply new self-adhesive foam or door sweep. Good weather stripping can reduce heating and cooling costs by 10–20%.
