Before you start looking for one, you should pick what material you would like. The most popular materials to choose form are wood, aluminum, and vinyl. If you like the look of wood better, aluminum can be painted to look like wood.
For installation, you could pay somebody else to do it, or you could look for aluminum pergola kits to save money by installing it yourself. Aluminum pergola kits include all necessary materials cut to size.
One benefit that you may not realize is that getting the kit delivered to your door will save you a lot hassle. This is especially handy if you do not own a big truck to carry all the materials from a store. When you first start planning to build a pergola, you might not think about things like how much room you have in your car, but you will not have to worry about that if you order a kit and have it delivered.
The kits will come with plans and detailed step-by-step instructions. Yes, you will have to do some work, but just think of how much money you are saving by putting it together yourself. Just follow the instructions exactly and you will be relaxing under the shade of your pergola in no time. You can use the extra money you saved to purchase some hanging plants or climbing vines. The best part will be the sense of accomplishment you will feel after it is all put together and you are reaping the benefits.
