How to Fix a Drafty Window with Inexpensive Weatherstripping

Cold drafts around windows waste heating energy and make rooms uncomfortable. Self-adhesive foam or rubber weatherstripping from any hardware store seals the gap in minutes — no special tools needed.

Clean the surface with rubbing alcohol first so the adhesive sticks properly, and replace the strips every two to three years.
