Mounting plastic blinds is a task that we may need to do sometime or other. It is definitely a relatively straightforward task, which you should always try doing yourself, rather than paying an installer to do it. Let us outline the basic steps involved in mounting them on the outside of a window. It is best to have someone giving you a helping hand, so as to hold the blinds for you, since you will most likely be on a ladder most of the time to do the drilling and mounting.

Step 1 - Measure

First of all you have to acquire all the tools you'll need. Using a measuring tape record the dimensions, and while you are at it mark the place where the blinds rail will be mounted. Next, order your blinds according to the measurements taken. Make sure to specify that you will be mounting the blinds outside the window. In this case it is best to make the blinds slightly larger than if they were going to be installed inside. This is due to the fact that they will be exposed to a greater amount of light outside. Hence, if they are not made to be larger than the window's gap, the sun's rays will end up passing in from around the edges. So, measure the window's height and length, and then add a few inches on each side.

Step 2 - Marking and drilling

The points you marked will serve as a guide for you to install the brackets and the head rail. The headrail will need to be a few inches up from the upper edge of the window. Using the markings you made previously, drill holes on either side of the window. If the window is wide, you may need to make at least another hole in between so as to support the blinds better. Measure from both sides so as to make equal spacings. While doing this use a levelling tool so as to make sure that you will carry out a neat job.

Step 3 - Installing the brackets

Next, you have to install the brackets. They will need to be screwed in the holes you made. Make sure to fix them tightly and securely. Some people also prefer to press an anchor into each hole for added security. Then, connect the mounting clips.

Step 4 - Install the head rail

Once the brackets have been fixed, you can snap on the head rail onto the mounting brackets. Some models may simply require that you slide it through. The blinds should click into place if everything has been fixed appropriately.

Step 5 - Fix the valance

Then attach the valance over the head rail. This will make the blinds look neater.

Step 6 - Connect the pulley or cords

The pulley which will be used to regulate the blinds should be connected. Some blinds may simply work by means of cords. They could be readily installed, or else you may need to fasten them. When ready, check that once the cords are pulled, the blinds will open and close neatly and without problems. If you feel that when you pull the blinds tilt slightly, or block, you might need to make the necessary adjustments.
