What to do
- Note your blind's exact width and whether it's a lift cord, tilt cord, or ladder tape that broke.
- Purchase a restringing kit sized to your blind, or matching replacement cord if you're comfortable measuring the original.
- Remove the headrail cover to access the internal spool or cord lock mechanism.
- 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.
- Reattach the cord to the bottom rail and tie it off securely, trimming excess length.
- Reinstall the headrail cover and test the blind's full range of motion.
- 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.
