Parts Needed

Step 1 – If your blind has a valance, remove it and set it aside.

  • Some blinds may not have valances attached.

Step 2 – Determine the string amount needed to complete your blind repair.

  • Use the following formula to determine the amount of string needed.
    [(2 x length) +width] x number of lift strings

Step 3 – Cut all of the strings you need for this repair.

  • We recommend replacing all of the strings in your blind to ensure proper operation.

Step 4 – If your strings are frayed but still intact, the blind can be restrung without removing it from the window.

Step 5 – If the strings are missing or broken, the blind will need to be removed from the window.

Step 6 – Cut off the tassels, and remove the safety washers.

  • Set aside these parts.
  • Some blinds may not have safety washers.

Step 7 – Pull the lift string from the bottom rail and cut the knot off.

Step 8 – Start here to restring a blind that has frayed but unbroken strings.

  • Fuse the ends of the strings together by melting the end of the old string to the new string.
  • Roll the strings together to join them.

Step 9 – Tie a knot at the end of the new string.

Step 10 – Pull the string through the blind until the knot on the new string is seated at the bottom of the blind.

Step 11 – Cut off the excess old string.

Step 12 – Start here to restring a blind that has broken or missing strings.

  • Remove the old string from the blind.

Step 13 – Blunt the end of the new string to prevent fraying.

Step 14 – Starting at the top of the blind, thread the string down through the slat holes.

  • Alternate sides of the ladder support pieces every three slats when threading the new string.
  • This ensures that the slats won’t shift during operation.

Step 15 – Thread the new string through the bottom rail.

Step 16 – Tie a double knot on the end string, and cut off any excess string.

Step 17 – Remove the blind from the window.

  • Lay the blind on a flat surface.

Step 18 – Thread the wire restring tool through the cord guide at the bottom of the headrail.

Step 19 – Thread the string through the eye of the tool, and pull it through.

Step 20 – Using the wire tool, thread the string through and around the cradle.

Step 21 – When rethreading the cord lock, thread the strings between the roller and the latch.

  • Threading the string may vary depending on your cord lock.

Step 22 – Remount the blind.

Step 23 – Test your repair.

  • Test your repair by raising and lowering the blind. Make sure that the blind locks in place properly.

Step 24 – With the blind down, attach the safety washers two inches from the top.

Step 25 – Cut the lift strings to the desired length, and reattach the tassels.

Step 26 – Attach the valance.
