Cut down horizontal blinds that are too wide
Sometimes blinds are mis-measured or ordered the incorrect size. Below are instructions for cutting down the width of horizontal blinds.
Note: Some of these repairs will void the warranty!
In order to cut down the size of your blinds you may have to cut down the valance, headrail and slats. Directions for each are provided below.Blind HeadrailBlind SlatsBlind Valance
Cutting down the blind headrail
For the headrail you can use a hacksaw or a
pair of tin snips to cut it. Don't worry too much about the looks of the
headrail cuts because you wont see them once they are placed in the box type
- Measure in the distance you would like to cut and mark a line. You can cut an even amount off of each side of the headrail or if it is a small amount, just cut it off of the lift cord side of the headrail.
- Remove the end stiffener from the headrail.
- With the tin snips or hacksaw, carefully cut the headrail along the mark you made. As you cut the headrail you may want to bend the cut portion out of the way with pliers or a screw driver.
- Bend the ends of the headrail back out into position with pliers or a screw driver.
- Replace the end stiffener back into the headrail of the blinds.
Cutting down the blind slats
If the blind slats are too wide use a powered saw of some kind. We recommend changing the blade to one that
doesn't have much bite on it. Go slow with the saw. If you are using a
hand saw try using a hacksaw rather than a standard carpenters saw. Just
remember that in order to do a good job you must take your time and go slow.
- Align the slats on the blind so that they are even.
- Using a clamp or rubber bands, secure the slats together into position.
- Wrap the slats with masking tape to prevent chipping.
- Measure where you want to cut and mark a line with your pencil. Make sure that the masking tape covers the entire area you are cutting.
- Lay the blinds on the saw and line up the blade wheree you need to cut. Make sure that you take int to account the width of the blade
- Make sure that the headrail and the clamp is not interfering with the
saw. You can slide the headrail to the side out of the way.
- Slowly cut through the tape and slats
- Remove the tape and clamps or rubber bands.
Cutting down the blind valance
If the valance is too wide to fit within your window sill, follow these simple steps to cut it down.
- Mark with a pencil where you want to cut the valance. You can either measure your window and cut the valance at 1/8" under the width, or just simply put the valance up to the window and make a mark 1/8" shorter.
- Place the valance in the saw and line it up with your mark
- Cut the valance. Go slow to prevent chipping.
