So Fido got his head caught in your horizontal blinds and broke a couple slats trying to get loose. It happens. Whether wood, faux wood, fabric, or aluminum, put enough stress on the slats and they’ll eventually break. Or bend. Or warp. Whatever the damage, the good news is you don’t necessarily need a whole new blind. If everything else is still in working order, it’s easy to replace and fix your blinds with just a new slat or two -- without even taking your blind out of the window! 

Here’s how to fix your horizontal blinds:

Lift and tilt cords on horizontal blinds
Bottom rail plugs on horizontal blinds

  1. First, remove the plugs located on the bottom side of the bottom rail to reveal the knotted lift cords that run through the route holes on both sides of the blind.
  2. Untie the knots, then, at the broken slat, start pulling the lift cords up through the route holes until you reach the one you’re removing. (If you’re replacing more than one horizontal slat, start pulling cords from the highest damaged slat.)
  3. Remove the broken slat(s) from between the ladder strings, and slide in your new replacement slat so they’re resting on the ladder rungs (the little horizontal strings between the ladders that hold the blind slats in place).
  4. With your new replacement slats in place, thread the lift cord back through the route holes in each slat in the blind. Alternate the lift cord from left to right on each ladder rung as you work your way down the blind.
  5. When you reach the bottom, insert the lift cord through the hole in the bottom rail and tie a knot. Make sure the lift cords are even and that the bottom rail hangs straight.
  6. Last but not least, replace the plugs back into the holes on the bottom of the bottom rail. Tap gently with a rubber mallet or hammer to ensure they’re firmly in place (and you don’t leave any marks on the plugs or rail).
