How to Restring a Mini Blind: A Simple DIY Fix

If your mini blinds are not functioning properly due to damaged or frayed strings, you don’t need to replace the entire unit. Restringing a mini blind is a simple and cost-effective fix that you can do yourself with a few basic tools and materials.

Determining the Needed String Length

To figure out how much replacement string you’ll need, measure the length of your mini blind and double it. Then, add the width of the blind. This will ensure you have enough string to properly restring the entire unit, not just the damaged section.

Preparing for the Restringing Process

Start by removing the tassels and any washers from the bottom of the blind. Then, pull the string from the bottom rail and cut the knot. Next, remove the old string from the blind and use a lighter to melt the end of the new string to prevent fraying.

Rethreading the Strings

From top to bottom, thread the new string down through the slat holes and into the bottom rail. Tie a knot at the bottom to secure the string. If necessary, remove the blind from its brackets or mounting to access the cord guide at the top of the headrail. Use a wire restringing tool to thread the string through the cord guide and around the cradle, making sure to thread it between the roller and latch of the cord lock.

Finalizing the Restringing

Reinstall the blind and test the operation. If it’s working properly, reattach any tassels or washers. If the cords are not broken, you can skip the full removal and simply replace the damaged cord by welding the new string to the old one using a lighter.
