Before attempting to remove Levolor blinds, closely examine the brackets that hold the head rail to the top of the window opening. Some brackets have a small, hinged flap that clamps down over the front of the head rail, holding the head rail and, consequently, the rest of the blind in place. If there is no small flap covering a small section of the front of the head rail, then the bracket is probably the type that holds the head rail in place with a barbed clip.
Identify Bracket Type
Determine the Tools Required
If you are dealing with a bracket that has a small, hinged flap, you will need a flathead screwdriver as well as a ladder. If the brackets have no flaps, then you will probably not need any specific tools other than a ladder. In either case, you should also have eye protectors. Pull the cord that brings the slats upwards and lock the slats in the high position by pulling the cord to the right, or in some cases, to the left.
Loosen Brackets With Flaps
Put on your eye protectors. Climb the ladder until your head is at least as high as the bracket. For brackets with flaps, place the flat tip of the screwdriver under the lower edge of the flap and pull it forward and up. When these flaps were snapped shut during installation of the blinds, they "locked." Therefore, it will take some strength to get the closure of the flap to unsnap. After one end flap is opened, open the other one in the same way. Grasp the head rail and slide it toward you and out of the brackets.
Loosen Brackets Without Flaps
If the bracket has no flaps, after securing your eye protection, simply place your hand firmly over the head rail near the bracket and twist the top of the bracket down and toward you. You will most likely hear a "snap" when the barb has released the head rail. After one bracket is unsnapped, repeat the procedure with the opposite bracket before attempting to slide the head rail forward and out of the brackets.
