How to Install Window Blinds in Less Than 20 Minutes

Learn how to install window blinds in your home and eliminate the cost of hiring a window blinds installer. Window blinds are one of the easiest window treatments to install, and there are many design options beyond the usual white blinds that you see in many homes.

Window Frame

First you need to know the measurements of your window frame, which is usually measured from top to bottom and left to right. You can find this information on the manufacturer’s website or by contacting them directly. If you don’t have access to these numbers, measure the width and length of your existing windows with a tape measurer. Then add 1/2 inch for each side so it will fit snugly into the opening. This measurement should be used as a guide when choosing new blinds.

Next, take note of where the hardware goes. The most common type of hardware found on standard wood-frame windows is called “slat” style. Slats run horizontally across the window, while vertical bars hold up the slats. These horizontal bars are often referred to as “cords.” There may also be some decorative trim around the edge of the window frame. Measure all of these pieces carefully before buying any blinds.

Once you’ve determined what size blinds you want, look at the different styles available. Blinds come in three basic types: Roman shades, roller shades, and cellular shades. Each has its own advantages and disadvantages.

Window Casing

the window casing is made out of aluminum, vinyl, fiberglass, plastic, etc., depending upon the material of choice. It serves two purposes; first, it provides an attractive appearance to the window, second, it protects the interior surface of the glass itself. When selecting casings, make sure they’re strong enough to support the weight of the blind without breaking. Also consider whether or not the casing needs to be painted or stained. Some people prefer their casings to match the color scheme of their house, others like to paint them to coordinate with other colors in their decorating schemes.

The next step is to determine if you’d rather use a single piece of fabric or multiple panels. Single panel blinds offer more privacy than double or triple panel designs because only part of the room is visible through the blind. However, if you plan to open the blind frequently, then having several smaller panels might work better. Double and triple panel blinds allow you to control light entering the room even though parts of the room remain hidden behind the blind. They do require more space between the individual panels, however.

Once you decide on the number of panels needed, choose the appropriate shade. Most manufacturers provide sample sizes of various lengths and widths.

Pilot Holes

To install your own blinds you’re going to need to drill pilot holes in the wall. Pilot holes are small holes drilled into drywall walls prior to installing screws or nails. By drilling pilot holes, you’ll ensure that the screw heads won’t protrude above the finished surface once installed. To create the perfect hole, start by measuring the distance from the floor to the ceiling. Next, mark off the height of the desired blind using a pencil. Finally, place a straightedge over the marks and draw lines perpendicular to the edges of the straightedge. Use a power drill fitted with a 3/8″-diameter bit to bore holes along both sides of the line. Be careful not to hit the corner of the wall!

Now comes the fun part – hanging the blinds. First, remove the old blinds. Depending on the type of blind being replaced, you may just pull down the cords holding the blind together. For a roll-up blind, simply lift the entire unit away from the wall. Remove the mounting brackets attached to the headrail. Now, attach the new blind to the brackets. Slide the bracket onto the wall until it snaps into position. Attach the cord. Adjust the tension on the cords to suit your taste. And voila!

Faux Wood Blinds

If you want something different for your windows but don’t have the budget for real wood blinds, faux wood blinds can give you all the benefits of traditional wooden blinds at a fraction of the price. Faux wood blinds come in a variety of styles including: Venetian, roller, pleated, cellular, vertical slat, horizontal slats, Roman shades, and woven fabrics. You can also find custom designed faux wood blinds as well. If you want to add some style to your windows while saving money, faux wood blinds could be the answer.

You can now select faux wood window blinds, mini blinds with decorative tapes, or versions with built in valances.

They’re easy to maintain and incredibly cost-effective, particularly if you self-install.

Follow these simple tips to install window blinds in your home.

  • Remove your current window treatment. If there are any holes that will be exposed after you hang your new blinds, you’ll need to fill them with joint compound.
  • Check your walls. You may need special mounting hardware and tools if you’re working with a particularly hard surface like brick.
  • For an outside mount, in which the blinds are hung above the window casing and extend beyond the edges of the window:
  • Measure approximately 3 inches past each side of the window, above the window far enough to allow enough space for the mounting bracket, and slightly below the window. Screw the side brackets into the wall above the casing.
  • For an inside mount, in which the blinds are hung inside the casing, leaving it exposed:
  • Measure the window height at the top, middle, and bottom and use the narrowest of the three measurements. Repeat the same process for the width.
  • Screw the side brackets into the wall on the jambs above the casing.
  • For all windows:
  • Make sure that the brackets are straight with a level.
  • Untangle knots in the cords or tape.
  • Clip the headrail into the brackets and close the bracket covers.
  • If you have a valance, install the clips, and snap the valance into them.
