There is no need to replace the entire set of blinds just because the ropes that raise and lower them are broken or frayed. Often, only ropes can be replaced with a fraction of the expense.
Steps
Step 1. See how the blinds work and identify the problem
- Where is the problem? Is the rope broken or frayed? Or did it wind its way to one side and get out of its lane?
- Follow an intact rope. From the gusset (the piece of plastic you pull), most of the ropes go up, through some sort of hook that pulls them, into an empty channel at the top of the curtain, and down along a series of holes in the slats. From there it is secured by tying it along the channel on the bottom that rises and falls when you open and close it.
- There is another set of ropes, formed like a ladder, which rotates the curtain slats.
- Take pictures of this step if you think you will need help remembering what goes where once you get the strings off. If you have a set of blinds that work just as well as the ones you are repairing, you can use that as a reference instead.
Step 2. Determine the size of the rope you will need
Wrap an intact section of the string 10 times around any cylindrical object, such as a pencil or screwdriver. Tighten the turns together, measure the width, divide by 10, and if necessary, convert inches to millimeters by dividing by 25, 4 (or using an online converter). The mini curtain cord is measured in millimeters (mm).
Step 3. Determine the length of the rope you will need
Measure the full height of the curtains. Measure along the top end, from the furthest string. Then measure down the part of the string that hangs down. Add these numbers, and then multiply the total by the number of cords that are on the curtains or by the number of cords you will replace. If your curtains are very old, the best idea might be to change them all at the same time. If you are unsure, order some extra. Rope doesn't cost much, and there's a good chance you'll need it for other curtains in the house sooner or later.
Step 4. Remove the curtains from the window
The exact procedure for this step will depend on the type of curtains you have. In general, they are mounted from the top.
If you can't understand how they fit by looking at them, consult the manual or installation instructions. If you don't have a hard copy, try searching for the make and model online
Step 5. Find access to the top and bottom
This also varies depending on the make and model of the blinds. Most Venetian blinds have access to the top once removed from the window. On the bottom, you have to remove a panel or cover, or slide a drawer.
Step 6. Remove the string at one end
It is best to replace one string at a time. Here we started from the bottom of the curtains, but you can safely start from the opposite side.
Step 7. Begin threading the new string through the base of the curtains and up along the row of holes
In this case, follow the route of the old rope around the paddles instead.

Image If the old string is worn but not broken, one way to insert the new one is to attach the end of the new string to the old one with duct tape. Then, the new rope will be on as soon as the old one comes out. Use masking tape, packing tape, or plain transparent tape. Either way, make the joint as thin as possible. You may need to guide it through some openings.
- If the old rope is broken, follow the path of an intact one as a reference and use a tapestry needle, small crochet hook, or a loop of cord or wire to guide the rope along the way.
- You may need to cut or untie the knots that held the old rope in the anchors and on the bottom rail. Save the old anchors for reuse, or replace them with new ones if they are damaged.
Step 8. Secure the rope to the bottom rail
Tie it securely through the holes, making sure the knot doesn't come off. This curtain has a couple of holes where you can tie the rope. Some curtains include a small seal or paddle to which the cords are tied. replace it if you have to. Otherwise, tie a knot large enough not to go through the hole.
Step 9. With the blinds closed, leave some excess length on the end to be pulled
Pass any other ropes and legal.
Step 10. Replace any covers or panels you removed to access the bottom rail
Step 11. Hang the curtains and check that they work properly
Step 12. Replace the dowels and secure a knot under each
With the curtains closed, shorten the pull cords so the ends don't show when you pull the dowels down.

Advice
- If you can't find replacement cords at your hardware store, or if you need a special size or color, order them online. Many sites also offer other replacement parts, such as plastic dowels at the end of the ropes.
- If the blinds are old, you may want to take the opportunity to clean them or have them cleaned while you have them down.
- Check the list of local repair shops if you'd prefer someone to do this job for you.
Warnings
- If your blinds include safety mechanisms on the ropes to prevent them from tangling, replace them on the new ropes.
- Venetian blind ropes are a strangulation hazard for small children. Keep them out of their reach.
