Weather Stripping: lifespan, maintenance and replacement

Typical lifespan: 3–7 years (about 5 years).

Maintenance schedule

• Inspect all exterior doors for gaps — Twice a year (spring & fall)
• Check windows for drafts — Annually (fall)
• Clean surfaces before reapplying adhesive strips — As needed
• Test with dollar bill test (close door on bill — if it slides freely, replace) — Annually

Signs it needs replacing

• Visible gaps when door is closed
• Drafts felt around doors or windows
• Weather stripping is cracked, flattened, or peeling
• Daylight visible around door frame
• Increased heating/cooling bills
• Insects or dust entering around sealed areas

Tips

V-strip (tension seal) lasts longest for doors. Foam tape is cheapest but wears out fastest.
