Window blinds can be a necessity, serving a basic function of preventing too much sunlight from seeping in. They come in various styles and materials and can add style to any home. After a while, blinds can begin to wear out just like anything else. Common problems are broken strings and blinds that won't tilt or raise or lower and sometimes don't hang evenly. Knowing how to repair the blinds yourself can be more economical than purchasing a new unit.

  1. 1

    Inspect the head rail of the blinds and check if the cord is caught in it if they will not hang straight. Remove the cord if it is stuck and raise and lower the blinds with the lift cord. This should fix the problem.

  2. 2

    Unhook the blinds from the brackets on the wall and undo the knot at the end of the cord or snip with scissors to replace a broken or worn-out string. Set the blinds on a flat surface and unwind the cord from the holes in the slats.

  3. 3

    Hold the old string next to the new one and use it as a template. Cut the new one accordingly. Shove the string through the hole in the cord lock in the head rail. Lace the strings through the openings in the slats.

  4. 4

    Push the cord in through the hole in the last rail. Make a knot just beneath the bottom rail to secure the cord. Hang the blinds back on the wall and check that the length is correct.

  5. 5

    Fix broken or damaged slats by removing the blinds from the wall and placing them on a flat surface. Slide the bottom rail off and undo the knots to replace the slats. Pull out all the slats up to the broken one. Set a new slat in the string ladders and put the old slats back. Replace the bottom rail and tie the cord beneath it. Hang the blinds back on the wall.

  6. 6

    Turn the blinds' tilt wand counterclockwise while they are closed and facing down if the blinds will not tilt. At the same time, tug on the back string on the ladders that are holding the slats.

  7. 7

    Twist the tilt wand clockwise while you are gently pulling on the rear string of ladders. The blinds should be closed and facing up.

  8. 8

    Replace the tilt wand if the blinds still will not tilt. Remove the metal piece out of the head rail and the same side the wand tilt is on. This is the end stiffener. Take out the C-clamp in the rod and slide the tilt rod from the wand tilter. Pry open the head rail with a screwdriver and remove the wand. Pull out the wand tilter with pliers. Push the wand tilter back into the opening. Put back the C-clamps, rod and end stiffeners. Hang the blinds back on the wall.

Tips and warnings

  • Check with a professional about the appropriate string width and strength for the blinds, because they come in an assortment of sizes.
