One of the advantages of bamboo blinds is that they are very durable and can last as a window feature for many years, with simple repairs. Occasionally, however, you may break or cut the string that raises and lowers the blinds. Armed with a replacement string from the blind manufacturer, you can implement a restringing method so that you can restore your bamboo blinds to their original state.
Contact the manufacturer of your bamboo blind and order a replacement string. If you do not know the manufacturer of your bamboo blind and don't remember where you bought it, go to a window and blinds shop where you may be able to buy a generic string that will work with your bamboo blinds.
Measure the amount of string that you will need for the project. Do this by adding together three measurements: the distance between the bottom cord ring to the head rail; the distance between the head rail to the middle of the shade; and the width of the cord track to the cord lock. Add those three measurements together and you will get the total length of the string that you need for the project.
Cut the string to the exact length of the measurement.
Push one end of the string through the cord lock mechanism. While bamboo blinds vary depending on the type and brand, this will most likely be located at the top-front of the blind. Snake the string over and under each pulley, starting at the innermost track on the right-hand pulley. Work all the way to the left-hand side repeating the over and under method.
Pull the string down once you have reached the last pulley on the left side. Pull the string to the very bottom of the blind.
Repeat the method with a second string if your bamboo blind has a cord lock mechanism with two chambers instead of one. If the mechanism has two chambers, insert a second string of the same length into the right-hand top of the blind. This time, snake the string over and under each pulley, starting at the outermost track on the right-hand pulley. Work all the way to the left-hand side repeating the over and under method. When you are at the left side, pull the string down to the very bottom of the blind.
Tie the ends of the two strings together in a simple knot. If your blinds come with a plastic or wooden piece for pulling the cord, attach it to the string and then make a knot.
Pull the string or strings to make sure that the pulley system is working properly.
If you have a specialised blind with additional features, such as middle guide rings, double shades or roman bamboo blinds, contact the manufacturer for specific instructions for how to restring the specialised system.
