Tools Needed

Phillips Screwdriver
Flat-head Screwdriver
Tape Measure
Needle-nose Pliers

Step 1 – Measure the length and width of the shade, and cut the strings you’ll need for this repair.

  • Use the formula to determine the total amount of string need for your repair:
    2x the length + the width multiplied by the number of lift strings.

Step 2 – Loosen the Phillips screws on the brackets behind the shades two full turns.

Step 3 – Remove the shade from your window, and lay it on a flat surface.

  • The shade will pull out towards you when removing.

Step 4 – Remove the condensers and tassels, and set them aside.

  • Your condensers and tassels may look different from those shown in the video.

Step 5 – Remove the cord lock and end cap from the top rail.

Step 6 – Slide the top rail off of the fabric.

Step 7 – Turn the shade over.

Step 8 – Use pliers to pull the string in the bottom rail pocket and ferrule out of the shade.

  • Remove the ferrule from the string, and set it to the side for reuse.

Step 9 – Pull the old strings out of the shade and discard them.

Step 10 – Thread the new string through the eye of the restring needle. Starting at the bottom rail, push the needle up through the fabric.

Step 11 – Thread the end of the string through the ferrule, leaving about an inch of string to tie it off.

Step 12 – Pull the string through to seat the ferrule into the pocket in the bottom rail.

  • Repeat these steps for all other lift strings.

Step 13 – Turn the shade over and install the cord guides.

  • Thread the string through the underside of the cord guide.
  • Place the cord guide into the hole punched in the fabric.
  • If the guides are damaged on one side, replace them or rotate them 180 degrees.
  • Direct all strings to the same side that the cord lock will be installed on.

Step 14 – Slide the top rail on to the shade fabric. Be careful not to snag the fabric.

Step 15 – Replace the headrail end cap.

Step 16 – Thread the string through the cord lock and latch.

  • Make sure the string is inserted in between the two metal bales on the cord lock.

Step 17 – Insert the cord lock into the top rail.

  • Make sure that the strings do not get snagged or pinched inside the headrail when installing the lock.

Step 18 – Rehang the shade.

  • Slide the top front part of the shade into the brackets first.
  • Make sure the bracket is seated into the slot at the front of the headrail.
  • Tighten the screws to secure the bracket.

Step 19 – Test your repair.

  • Raise the shade up and let it down. Make sure it locks in place correctly.

Step 20 – With the shade all the way up, cut the strings a few inches below where the shade should stop when lowered.

Step 21 – Install the condenser, tassel and pull cord.
