Safety
Potential burglars and other unwanted guests will have a difficult time entering your property with a high fence standing in their way. Some property owners even resort to using an electric fence. Depending on your area, you might also want to keep out unwanted animals. In either case, a fence will help prevent damages to your yard and home, as it will act as a barrier against intrusion.
If you have pets or young children, a fence can work in a reversed role; it will ensure they don’t run off into the street or get lost wandering.
Privacy
Without a fence around your yard, anyone can just walk up and see what you’re doing. Even if you contain your activity within your house, a passersby can easily see into your windows if you don’t draw the curtains or shut the blinds. A solid fence can remedy this issue because it will block the view, leaving you with more privacy. It gives you peace of mind to freely sit outside (or inside) and go about your business without disturbance.
Appearance
Beyond utility, a nice fence can make your home feel more complete and more beautiful. It will also increase your home’s value should you ever decide to put it up for sale. If this is important to you, opt for a style that complements your home’s exterior and yardwork. Research the different types of fences to make the best choice for you. As you look through the options, check to see if there are any community standards that you must adhere to—ignoring certain guidelines will likely create problems.
