How to Repair Roller Blinds

By Amanda Morin

  • Overview

    When they work well, roller blinds can be a great way to block out light without tangled cords or expensive curtains. When they need repair, however, watch out. The problems can vary, anywhere from whipping up so fast that the blind launches off the window, to being so loose that all you need to do is give a little tug and the whole shade unrolls. Luckily, roller blind repair isn't all that complicated.
    • Step 1

      Confirm that the mounting brackets allow the shade to retract freely. Roller blinds will need frequent repair if they are touching the window frame or sides when they retract, as this contact can rip the edges of the shade, making them roll unevenly.
    • Step 2

      Make sure the mountings are aligned and level. Use your tape measure to confirm that the mountings are the same distance from the top and bottom of the window, so that the roller blind isn't sitting crooked. Double check this by placing your level on the mounted, rolled-up shade. The bubble should be completely centered.


    • Step 3

      Repair a roller shade that retracts too fast and doesn't pull down easily by loosening the spring tension. Roll up the shade and take it off the brackets. By hand, unroll it about midway and remount it. Test to see if this has loosened the spring. Try this two to three times before moving on to other troubleshooting methods.
    • Step 4

      Adjust a locked spring to loosen the tension. With the blind removed from the mount and partially unrolled, grasp the flat pin on the end of the blind with a pair of pliers. Turn clockwise and, once you feel the pawl click off the ratchet, quickly let go of the pin.
    • Step 5

      Repair a loose roller blind by tightening tension. Take down the blind and roll it up tightly by hand, making sure to keep it even. Return to the brackets and check to see if the tension has increased.
    • Step 6

      Attempt to tighten the tension in the spring if Step 5 hasn't worked. This may mean the spring has uncoiled and needs to be repaired to allow the ratchet mechanism to work correctly. Again, grasp the flat pin with your pliers and turn it. Once you feel tension, stop turning and the pawl should hook back to ratchet.
    • Skill: Moderately Easy
    • Ingredients:
    • Pliers
    • Screwdriver/hammer
    • Tape measure
    • Straight edge
    • Level
    • Duct tape
    • Stapler
    • Tip: The blind works using a pawl-and-ratchet mechanism. The pawl is a metal piece that hooks around the flat pin on the end of the blind, and the ratchet is the round cover piece around the pin. This latch system allows the shade only move in one direction.
    • Tip: You can fix slightly torn blinds using duct tape. Unroll the blind all the way and line the top edge of the blind up with the roller. If most of the top edge is attached, simply put the torn edge back in alignment and attach it with a small piece of tape. Alternatively, you can staple it into place.
    • Tip: You may need to replace the fabric if it's torn in multiple places. Simply mark a straight edge using a ruler and a pencil and tape or staple the new fabric in place.
