Affordable and versatile, vertical window blinds are easy to install yourself. Read our installation guide to learn how. Vertical window blinds are easy to install and one of the more affordable and versatile home window treatments available today.

Since vertical blinds are large and unwieldy and awkward to handle, you’ll want an assistant to manage this project efficiently. It’s also more fun if you have a partner to help!

But hang on to your cordless drill and step ladder; this easy to use, step by step vertical window blinds installation guide will show you the way!

If you can climb a ladder and use a cordless drill  you can do this project.

Why Choose Vertical Blinds?

Vertical window blinds these days can have vanes made of wood, metal, polyvinyl or can even be covered with fabric, making it easier than ever to find blinds to match any home décor or color scheme! They are also quite affordable in most cases, when compared to cellular shades or wood blinds.

Vertical blinds are a great choice if you have kids or pets and work best for sliding glass doors and windows that open and close horizontally, since you can pull them open or shut as far as desired and angle the slats to control the amount of light that enters the room.

Be sure to measure correctly for inside versus outside mount installation when ordering your vertical blinds. You can buy vertical blinds at your local blinds retailer or home improvement center. Or, buy them online and save even more money; since you will be installing them yourself, you don’t need to pay the higher prices most retailers charge since their overhead includes paying employees who assist with fitting and installation.

Installing Your Vertical Blinds

As a precaution, always wear protective eyewear when using power tools! A pair of work gloves will also help protect your fingers and hands while installing your vertical window blinds.

  • You will need a few simple tools to install vertical window blinds:
  • A tape Measure, pencil and hole punch
  • Screw drivers (flat and Phillips head)
  • A hammer and finishing nails
  • Cordless drill, several sized drill bits, ranging from 1/16 inch to1/4 inch and a 1/4 inch hex head bit
  • A level
  • Scissors

Check the parts list included with your vertical blinds, which varies but generally should include:

  • Wall brackets and mounting clips
  • Nuts, bolts and mounting screws
  • Vertical blinds head rail
  • Vertical blind louvers or vanes
  • Chain and clip
  • A cord weight or clip

You will also need fasteners, which generally are not included with vertical blinds; the type of wall anchors to use depends on the wall and materials to which you are mounting the blinds:

  • Heavy duty, hollow wall anchors (good for heavy blinds)
  • Hollow wall toggle bolts (good for heavy blinds)
  • Plastic or lead anchor inserts
  • Plastic anchor inserts (lightweight blinds only)

How To Install Vertical Blinds

  1. Before you order your vertical blinds, be sure to measure your window according to whether you are ordering inside mount or outside mount vertical blinds; this is a crucial decision that affects your measurements and correct fitting! Inside mount blinds are mounted inside the door or window casing and look best in most cases.
  2. If you don’t have sufficient casing width or prefer the look of outside mounts, these will be installed on the outside of the casing or frame, which means the width will usually be greater than for inside mounts.
  3. Unpack your vertical blinds and carefully set aside all the mounting hardware, including clips, screws and other pieces. Be sure to read your manufacturer’s instructions thoroughly as the details can vary from one to another!
  4. Measure outward from the window approximately one inch and mark with your pencil, where the brackets will be installed; repeat on the other side of the window. Use the bracket to mark both holes for each bracket to be sure the holes line up properly.
  5. Use your hole punch to start the holes and then drill at these marks; if you are drilling into solid wood behind the sheetrock or you are drilling directly into the window casing, then you’ll simply use the mounting screws. If the wall space behind the holes is hollow, then you’ll need to use toggle bolts or wall anchors.
  6. Attach the blind to the brackets by sliding the holders into the grooves and install the rod for operating your vertical blinds. If your blind is over 62 inches wide and has additional clips in the middle, center and clip over the third groove and about four inches or less from each end.
  7. If your blind has a valance or dust cover, hold the valance up and line up the back of the valance up with the depth marks. Then drill holes through valance at the mounting hole marks. For mounting on a dry wall surface, use wall anchors and push them into drilled holes. Hold valance and clips up to the holes and drive screws through the clip and valance into the window sill or ceiling.
  8. Snap the head rail into place by inserting the front edge in the mounting clips and rotating back, with the pull cord on the right side for right draw or left side for left draw.

Vertical Window Blinds Installation Tips

  • CAUTION: To avoid danger of strangulation, a cord weight or tension pulley should be attached to the cord or chain and anchored securely to the wall, with two pull safety tassels attached!
  • To install the louvers, rotate the stems so that you can see through the slots and push each louver up into stem. Pull down gently on each louver to insure it catches on the stem hook.
  • For fabric covered louvers the hems should all face the same direction.
  • If the louvers do not rotate, check to be sure all louvers are overlapped the same; remove louvers and carefully reinstall them if needed.
  • For inside mount vertical blinds, the pulley should be positioned toward back of sill so it doesn’t interfere with louver rotation.
  • If the cord is too long, you can adjust it; adjust the louver holders to their fully stacked position and grasp the knot located along the inside of the track; pull out excess cord, retie the knot and cut away the excess cord.
  • If the cords are twisted after installation, open the blind completely, pull the knot that is farthest away from the end with the cords and chain. Use a pair of needle nose pliers to get at the knot and hold the cord near the knot and the cord near the drive end and twist both of them in the same direction. Twist one way and then the other until you find the right way to untwist the cord. Then pull the cords on the end of the blind to get the knot back inside the blind.
