While you probably could measure and hang window treatments on your own, it is not recommended. It is a difficult job that requires a certain amount of skill and patience. Furthermore, if you measure incorrectly for custom made window coverings it could be an expensive mistake.
First, you have to be honest to yourself about how handy you are. If you do not know a screwdriver from a hammer, home improvement jobs should be left to the professionals. This is true of all home improvement projects, not just 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 to take into consideration is the size and location of the windows being covered. They could be difficult to reach or have complicated arches. You made need scaffolding or a tall ladder to reach the windows needing coverings. Moreover, if you are covering many windows, the job could become tedious and overwhelming. It can also become time consuming to those that are not up on the most efficient ways to get the job done and have never done it before.
Another thing to take into consideration is if you are not the handy type or are not in construction by trade, you may not be familiar with all of the hardware and machinery required for the job. You will need specific brackets, screws, clips, supports, anchors, pulleys and the equipment to install them such as hammers, nails, screwdrivers and the like. You need to ensure that you have it all before you begin, or you will spend most of your time traveling to and from the local hardware or home improvement store. You also need to ensure that you have the correct sizes and shapes, as well.
The material you are working with needs to be taken into consideration as well. This includes not only what the window coverings are made of, but also what the walls are made of as well. It is generally recommended that the lighter the fabric, the lighter the hardware, unless you are working with concrete walls. You will need special machinery to get through the cement if that is the case in your home. If your walls are plaster, then you need anchors to support whatever you hang on the walls.
Furthermore, with as expensive as window treatments are, professional installation is recommended. No one wants to spend a ton of money on expensive drapes or blinds only to have the hung wrong, crooked or lopsided. Hiring a handyman or professional installer, you ensure that your investment looks its best and stays in place. By hiring a professional, you can avoid injury and get the most out of your purchase.
Stores that sell Hunter Douglas blinds, shades and shutters often employ installers or can recommend a few to you. After all, why spend a lot of money on expensive window coverings and then skimp on installation.
