One thing I do to prepare my home for the winter months in Chicago is to make sure all the windows and doors are properly sealed. The cold winds can really drive up heating costs if there are any drafts, so I go around the house and check for gaps, then add weatherstripping or caulk where needed. I also make sure to clean out the gutters, as they can easily get clogged with leaves and cause ice dams, which can lead to water damage. My advice to others would be to focus on the basics: check your insulation, service your heating system, and clear the paths outside to prevent ice build-up. Preparing early in the fall can save you a lot of headaches and energy costs during those brutal Chicago winters!
