    1. Lock every window. The lock pulls the sashes tight and closes small gaps.
    2. Close storm windows and check that weatherstripping isn't torn or flattened.
    3. Run your hand along the frame on a windy day. If you feel cold air, mark that window.
    4. Look for fog or moisture between the panes. That means a failed seal.
    5. Open curtains on sunny south-facing windows by day and close them at night.
