Venetian blinds come in a variety of materials, such as aluminum, wood, faux wood and vinyl. Depending on the material—wood, for instance—the blinds can be expensive. Over time, even expensive blinds can wear down and strings can break. You can save money in the long run if you replace the string yourself rather than purchasing new blinds. It just takes a few basic materials to restring your Venetian blinds. These instructions work for any horizontal blinds that use slats and a ladder system.
Take the blinds down from the metal brackets on the wall by lifting them out. Use a flat screwdriver to pry them from the brackets if they are not easy to get out.
Thread the new string through the hole in the cord lock located in the head rail and pull the string through the head rail. Feed the string through the openings in the slats.
