Vapor barriers & ventilation
An energy-tight home requires adequate ventilation and vapor control to maintain healthy air.
The primary areas to seal with caulk are:
If you find a large hole or crack, use expanding foam. A small squirt is usually enough to seal the opening - too much can damage the surrounding materials. Don't use expanding foam around any electrical equipment.
If you have storm windows, use them. If you don't, install plastic window film, especially on north-facing windows. Don't forget to cover basement windows too.

Spray foam insulation does a great job of sealing up cracks and crevices, if it's installed properly. Learn more about open-cell spray foam options.
