  • CommonCord caught and yanked hardA child, pet, or accidental snag can snap a stressed cord instantly.
  • PossibleSun-damaged cord materialUV exposure through the window can weaken cord fibers over time.

What to do

  1. Note your blind's exact width and whether it's a lift cord, tilt cord, or ladder tape that broke.
  2. Purchase a restringing kit sized to your blind, or matching replacement cord if you're comfortable measuring the original.
  3. Remove the headrail cover to access the internal spool or cord lock mechanism.
  4. Thread the new cord through the same path as the old one, following the kit's instructions or photographing the old setup before removing it.
  5. Reattach the cord to the bottom rail and tie it off securely, trimming excess length.
  6. Reinstall the headrail cover and test the blind's full range of motion.
  7. If cords break often on the same blind, consider upgrading to a cordless or motorized version for safety and durability.

When to call a pro

Call a blind repair service if restringing feels too fiddly or the blind's mechanism is unusually complex.

Safety

Use caution

Keep cords out of reach of young children and pets; corded blinds pose a strangulation risk, so consider cordless replacements in rooms where kids play.
