Hanging Blinds 101

Blinds are a very popular window treatment, and justifiably so: they are durable and stylish, they allow you to control natural light levels inside your home, and they make maintaining your privacy an easy task.

But, blinds that are incorrectly measured or poorly installed do not work nearly as well. Think about it: how can you really control the light levels in your home if there is a huge gap on the outside edge of your blinds? How can your blinds protect your privacy if they don’t fully cover your windows?

Accurately Measuring Your Windows for Blinds

What’s so complicated about measuring windows for blinds, after all? Well, they might appear to be perfectly square or rectangular, but in reality, many are not. Some windows are wider at the bottom than the top, or vice-versa, while others are wider in the middle. The header or sill might be bowed, or out of level.

If you want to make sure you get the most out of your new blinds, accurate measurements and correct installation are a must. That’s why at 3 Day Blinds we offer and recommend professional installation for all of your window treatments.

However, we know that some of you take pride in being do-it-yourselfers around the home, and we want to make sure you get maximum satisfaction from our products, whether you have us install them, or you do it on your own.

Hanging Blinds 101: What You Will Need

In order to install your new blinds, you’ll need a steel tape measure, a level, flathead and Phillips screwdrivers, a pencil, a power drill, and the correct drill bits. You may also want to use an awl for starting screw holes, but you can start them with a small drill bit just as easily.

Your 3 Day Blinds order will ship with all of the hardware necessary for a standard installation, but if you’re attaching your blinds to stone, tile, or brick, you’ll need specialized drill bits and plugs. For plaster and wall board installations, you’ll want to pick up some expansion or toggle bolts, in order to ensure a secure hold. Last, if you’re mounting your blinds to a wood surface, then don’t forget to pre-drill the holes, or you’ll run the risk of splitting the wood.

Inside or Outside Mount?

Once you’ve gathered your tools and acquainted yourself with the hardware, you’ll need to decide whether to do an inside or an outside mount.

Mounting the blinds inside the window frame is generally preferable, as doing so offers a cleaner look, and protects the blinds from damage. However, an outside mount may be necessary if there is inadequate depth for an inside mount, or if there are obstructions (such as window cranks) that would interfere with the operation of the blinds.

Installing Brackets

The next step is to install the brackets that your new blinds will attach to. For inside mounts, a bracket must be mounted in each upper corner of the window, and care must be taken to ensure that the proper clearances are observed. The front of the bracket should extend slightly beyond the front of the window casing, and the back of the bracket must be no farther than 1 ¾” back from the window casing’s outside edge.

Installing Blinds

Once the brackets have been installed, the blinds can be mounted to them. First, hang the front lip of the headrail onto the mounting bracket hook, with the headrail positioned between the teeth on the front of the mounting bracket. Then, simply push and rotate the headrail back onto the rear of the mounting bracket. Next, gently pull the headrail toward you, until it settles into the bracket.
