Replace window weatherstripping

Why It Matters

Worn weatherstripping lets in drafts, raises heating and cooling bills, and admits moisture, dust, and insects.

Tools

• Utility knife or scissors
• Tape measure
• Rag

Materials

• Self-adhesive foam or rubber weatherstripping

How to Do It

1. Starting at one corner, peel off the old weatherstripping from the channel around the window frame.
2. Wipe the channel clean and let it dry completely so the adhesive bonds properly.
3. Measure each side of the window opening and cut weatherstripping to length.
4. Press the self-adhesive strip firmly into the channel, working around the frame without gaps or overlaps at corners.
5. Close the window fully and confirm it latches without binding.
