How to Winterize Windows Before Cold Snaps in South Carolina

Most homeowners do not need a major project before the first hard freeze, just a careful check of the weak spots that let cold air and damp air move in and out.

If you stand near a window on a windy evening and feel a steady chill, the problem is often not the glass itself, but the perimeter around it. Look for cracked caulk, separated trim, loose sash components, and places where daylight shows through.
