Weatherize Your Windows and Save Big This Winter

- Mount insulated curtains to prevent conditioned air from escaping and maintain a consistent indoor temperature.
- Check thoroughly for broken or cracked windows, and fix or replace any damaged windows.
- Scrape any dried or cracked putty from the edges of your windowpanes and re-apply using a putty knife.
- Check for leaks by holding a candle near the outside edges of window frames. If the flame goes out or flickers, then apply caulk to seal the leak.
- Apply weather stripping around your doors and windows, which will allow you to open them after you apply it (unlike rope caulk).
- If your primary windows are still in good condition, install low-e storm windows; they can save 12%–33% in heating and cooling costs.
- If your home has very old or inefficient windows, consider upgrading them to new, energy-efficient windows. They’ll pay for themselves through lower heating and cooling costs over time.
