A blind is a popular window covering. Pulling your blinds up and down adds to each blind's wear. Blind strings begin to wear down and fray. Fragile strings can be quickly fixed as long as the damage doesn't exceed past the bottom rail. The actual cord that you use to pull the blind can also stop functioning. You can purchase replacement cords and replace them yourself. Another common issue is water damage. This is obviously only an issue for wood blinds. The damage can be fixed. which will keep you from having to replace the blind.
Open the slats of the blind and extend the blind all the way down. Then remove the blind from the brackets and place it on a flat surface.
Remove the cap that is covering the string hole on the bottom rail. You can use a screwdriver to force the cap off.
Cut the knot off the string with scissors to untie it.
Light the end of the new string until it catches fire. Blow out the flame and immediately push the melted end and the old string together. Roll the two between your fingers to melt them together. Be careful. The string will be hot. Tug the string to make sure it is secure.
Pull it through the blind or bottom rail. Cut away any excess string. Then tie the string into a knot.
Push back on the bottom rail cap.
Draw up the slats on the blind. Then remove the blind and set it on a flat surface.
Pry away the side cover from the top rail with a screwdriver or your fingers.
Pull the old cord away from the sprocket or wheel on the side of the blind.
Guide the new cord on the sprocket or wheel of the blind's clutch mechanism.
Thread the string through the guides in front of the sprocket with your hand. Then replace the cover. You have now installed a new string.
Open the slats on the blind, and extend the blind all the way down. Remove it from the brackets and place it on a flat surface.
Fill any cracks or defects in the slat with wood filler. Put the tip of the applicator near the defect. Push the filler out. Then smooth with your hand.
Sand down the water damage on the wooden slat with light-grain sandpaper. Wipe away any dust and debris with a dry, lint-free cloth.
Repaint the sanded area of the blind with matching paint. You will need a paintbrush to apply the paint. You can use interior house paint. If your blind has a glossy finish, use a glossy paint. You can also secure the paint finish with a gloss. To find the correct paint colour, take your blind to the paint shop to have it matched.
