How to Tighten Blinds
Tightening blinds doesn't require a professional. (venetian blind. image by guiney from

Occasionally, the spring in roller blinds may need to be tightened by adjusting the spring inside. A spring roller blind has a hollow tube with a coiled spring inside. Sometimes the spring will uncoil, making it difficult to lift and raise the blinds. It is possible to tighten the spring yourself with a few basic materials, which will save you money without having to hire a professional.

Skill level:
Moderately Easy


  1. 1

    Grab the blinds at the bottom and pull them down halfway to tighten the spring tension.

  2. 2

    Remove the blinds from the brackets in the window. Lift the blinds out of the brackets and place them on a flat work surface.

  3. 3

    Roll the blinds all the way to the top of the roller with your hands. Make sure the length is even.

  4. 4

    Set the blinds back into the brackets.

  5. 5

    Test the blinds to make sure the tension in the spring is correct and repeat each step if necessary.

Tips and warnings

  • If the spring is uncoiled, adjust the tension another way. Lift the blinds out of the brackets in the window. Unroll it partially with your hands. Locate the pin in the end of the roller and use needle-nose pliers to twist it until you can feel the tension increase.
