Mind the Window Gaps

If you can feel a breeze around your closed windows, consider these quick-and-easy ways to block drafts. Such stopgap measures eliminate air leaks by sealing sash perimeters from indoors. Come spring, add or replace weatherstripping for a longer-lasting fix

Rope Caulk

This clay-like ribbon comes in gray or brown. Peel off as many of the 1⁄8-inch strips as you need to fill a gap, and press them in place.They leave no residue, but aren’t reusable. The unused portion has a four- to five-year shelf life.

Foam Backer Rods

These closed-cell polyethylene rods come in a range of diameters, starting at 3⁄8 inch. They aren’t sticky—you press them into place, out of sight—and they’re reusable, if not deformed from being jammed too tightly.
