There a lot of good reasons to put up a fence around your house and your yard. There is so much crime in the world today that having a fence is almost necessary in a lot of parts of the world. Take Brazil, for example. People there don't even consider buying a house unless it has a big fence completely surrounding it, which is generally a big cement wall! And to add to this, they have bars in every window and have a big gate that allows the cars to enter and leave. This is every house!
So, with this in mind, we in North America should consider ourselves lucky that we don't have this kind of problem, generally speaking. However, there are still difficulties with robbery and theft that occur often with houses here, and believe it or not, they happen in your neighborhood too! So having a fence is a really good way to prevent this type of thing from happening to you.
So, now that you're convinced, and want to have a fence installed, what are your options? Well, there are a variety of privacy fences options and styles. Perhaps the best-known type of a fence is the chain link fence. This type of a fence is so well-known and popular because of its cost effectiveness and ability to do exactly what it claims to do: keep people out, or perhaps, keep animals or children in! Chain link fences are made of a thick steel cable which is interwoven to create a pattern that people cannot fit through. It is durable and tough, and very resistant to most ways to get inside. However, if you go for this option, you will need to improve it a little bit. What is mean to say is this: chain link is very easy to climb, unfortunately, so people will try to climb over this fence. However, if you place some razor wire or barbed wire along the top, they will not be able to do this.
Another option that you have is the wooden fence. This is made of durable boards that are placed in such a way as to prevent people from being able to see inside. These fences are often tall and very difficult to climb. They are also difficult to go through and make a lot of noise if they break. This means that your assailant is probably caught before he even begins. He would do better to attack some other, poor, unprepared schmuck that thought that a fence wasn't necessary! Unfortunately, this type of fence is often expensive, and the maintenance can be prohibitive as if you don't take care of the wood, it can rot within a few years, severely weakening it. Finally, there is the good old cow fence. As you've guessed, this kind of a fence isn't really for keeping people in or out, but rather it is good for keeping cattle inside a perimeter! This is most often used by farmers and is generally just a few strands of steel cable spanning a long distance. It is often also electrified, to make sure that the cattle know to keep away.
Ultimately, buying a fence for your yard is a great idea. It will help keep you and your family more secure and make you feel much safer.
