While you probably could measure and hang window blinds on your own, it is not recommended. It can be a difficult job that requires both skill and patience. Furthermore, if you measure incorrectly for custom made window coverings it could be an expensive mistake.
The first thing you have to is be honest with yourself about how handy you are. If you cannot tell a wrench from a hammer, home improvement should be left to the professionals. This includes hanging window treatments. After all, you are trying to cover your windows, not make a new one by way of a new hole in the wall.
The next thing you need to take into consideration is the size and location of the windows you will be covering. They could be difficult to reach or have funky arches. The job may require scaffolding or a tall ladder in order to be able to reach the windows that need covering. Moreover, if you are covering a lot of windows, the job could become overwhelming. It can also end up taking a long time because you are not up on the most efficient ways to get the job done and have never done it before.
Another thing to remember is if you are not the handy type or are a construction worker, you may not be familiar with everything required for the job. You will need specific brackets, screws, clips, supports, anchors, pulleys and other equipment in order to install the custom blinds, including hammers, nails, and screwdrivers. You need to be sure that you have it all before you begin and that it is all the correct sizes and shapes, or you will spend a lot of your time traveling to and from the local hardware or home improvement store.
You need to take into consideration the material you will be working with. This includes both the window covering materials and what the walls are made of, as well. It is recommended that the lighter the fabric, the lighter the hardware is. That is, unless, you are working with concrete walls. If that is the case, you will need special machinery to get through the cement in your home. However, if your walls are made of plaster, then you will only need anchors to support whatever you choose to hang on the walls.1
Furthermore, with as expensive as window blinds are, professional installation is recommended. No one wants to spend a ton of money on expensive shades, shutters, or blinds, only to have them hung wrong, crooked, or lopsided. Therefore, by hiring a handyman or professional installer, you can ensure that your investment looks its best and stays in place. Additionally, by hiring a professional, you avoid injury and get the most out of your purchase.
